DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.

[0030] The invention is susceptible to many variations, including scaling for capacity, in so long as process parameters are maintained. Accordingly, the drawings and following description of the preferred embodiment are to be regarded as illustrative in nature, and not as restrictive.

1. Terms

[0031] The term product means any machine, manufacture and/or composition of matter, unless expressly specified otherwise.

[0032] The term apparatus means the organic matter processing system in accordance with the present invention.

[0033] The term method or process means any process, method or the like, of using the apparatus of the invention, unless expressly specified otherwise.

[0034] Each process (whether called a method or otherwise) inherently includes one or more steps, and therefore all references to a step or steps of a process have an inherent antecedent basis in the mere recitation of the term process or a like term. Accordingly, any reference in a claim to a step or steps of a process has sufficient antecedent basis.

[0035] The term invention and the like mean the one or more inventions disclosed in this application, unless expressly specified otherwise.

[0036] The terms an aspect, an embodiment, embodiment, embodiments, the embodiment, the embodiments, one or more embodiments, some embodiments, certain embodiments, one embodiment, another embodiment and the like mean one or more (but not all) embodiments of the disclosed invention(s), unless expressly specified otherwise.

[0037] The term variation or variant of an invention means an embodiment of the invention, unless expressly specified otherwise.

[0038] A reference to another embodiment or another aspect in describing an embodiment does not imply that the referenced embodiment is mutually exclusive with another embodiment (e.g., an embodiment described before the referenced embodiment), unless expressly specified otherwise.

[0039] The terms including, comprising and variations thereof mean including but not limited to, unless expressly specified otherwise.

[0040] The terms a, an and the mean one or more, unless expressly specified otherwise.

[0041] The term plurality means two or more, unless expressly specified otherwise.

[0042] The term herein means in the present application, including anything which may be incorporated by reference, unless expressly specified otherwise.

[0043] The phrase at least one of, when such phrase modifies a plurality of things (such as an enumerated list of things) means any combination of one or more of those things, unless expressly specified otherwise. For example, the phrase at least one of a widget, a car and a wheel means either (i) a widget, (ii) a car, (iii) a wheel, (iv) a widget and a car, (v) a widget and a wheel, (vi) a car and a wheel, or (vii) a widget, a car and a wheel. The phrase at least one of, when such phrase modifies a plurality of things does not mean one of each of the plurality of things.

[0044] Numerical terms such as one, two, etc. when used as cardinal numbers to indicate quantity of something (e.g., one widget, two widgets), mean the quantity indicated by that numerical term, but do not mean at least the quantity indicated by that numerical term. For example, the phrase one widget does not mean at least one widget, and therefore the phrase one widget does not cover, e.g., two widgets.

[0045] The phrase based on does not mean based only on, unless expressly specified otherwise. In other words, the phrase based on describes both based only on and based at least on. The phrase based at least on is equivalent to the phrase based at least in part on.

[0046] The term represent and like terms are not exclusive, unless expressly specified otherwise. For example, the term represents do not mean represents only, unless expressly specified otherwise. In other words, the phrase the data represents a credit card number describes both the data represents only a credit card number and the data represents a credit card number and the data also represents something else.

[0047] The term whereby is used herein only to precede a clause or other set of words that express only the intended result, objective or consequence of something that is previously and explicitly recited. Thus, when the term whereby is used in a claim, the clause or other words that the term whereby modifies do not establish specific further limitations of the claim or otherwise restricts the meaning or scope of the claim.

[0048] The term e.g. and like terms mean for example, and thus does not limit the term or phrase it explains. For example, in a sentence the computer sends data (e.g., instructions, a data structure) over the Internet, the term e.g. explains that instructions are an example of data that the computer may send over the Internet, and also explains that a data structure is an example of data that the computer may send over the Internet. However, both instructions and a data structure are merely examples of data, and other things besides instructions and a data structure can be data.

[0049] The term respective and like terms mean taken individually. Thus if two or more things have respective characteristics, then each such thing has its own characteristic, and these characteristics can be different from each other but need not be. For example, the phrase each of two machines has a respective function means that the first such machine has a function and the second such machine has a function as well. The function of the first machine may or may not be the same as the function of the second machine.

[0050] The term i.e. and like terms mean that is, and thus limits the term or phrase it explains. For example, in the sentence the computer sends data (i.e., instructions) over the Internet, the term i.e. explains that instructions are the data that the computer sends over the Internet.

[0051] This description of preferred embodiments is to be read in connection with the accompanying drawings, which are part of the entire written description of this invention. In the description, corresponding reference numbers are used throughout to identify the same or functionally similar elements. Relative terms such as horizontal, vertical, up, down, top and bottom as well as derivatives thereof (e.g., horizontally, downwardly, upwardly, etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion. These relative terms are for convenience of description and are not intended to require a particular orientation unless specifically stated as such. Terms including inwardly versus outwardly, longitudinal versus lateral and the like are to be interpreted relative to one another or relative to an axis of elongation, or an axis or center of rotation, as appropriate. Terms concerning attachments, coupling and the like, such as connected and interconnected, refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise. The term operatively connected is such an attachment, coupling or connection that allows the pertinent structures to operate as intended by virtue of that relationship.

[0052] Any given numerical range shall include whole and fractions of numbers within the range. For example, the range 1 to 10 shall be interpreted to specifically include whole numbers between 1 and 10 (e.g., 1, 2, 3, 4, . . . 9) and non-whole numbers (e.g. 1.1, 1.2, . . . 1.9).

[0053] Where two or more terms or phrases are synonymous (e.g., because of an explicit statement that the terms or phrases are synonymous), instances of one such term/phrase does not mean instances of another such term/phrase must have a different meaning. For example, where a statement renders the meaning of including to be synonymous with including but not limited to, the mere usage of the phrase including but not limited to does not mean that the term including means something other than including but not limited to.

[0054] Neither the Title (set forth at the beginning of the first page of the present application) nor the Abstract (set forth at the end of the present application) is to be taken as limiting in any way as the scope of the disclosed invention(s). An Abstract has been included in this application merely because an Abstract of not more than 150 words is required under 37 C.F.R. .sctn.1.72(b).

[0056] No embodiment of method steps or product elements described in the present application constitutes the invention claimed herein, or is essential to the invention claimed herein, or is coextensive with the invention claimed herein, except where it is either expressly stated to be so in this specification or expressly recited in a claim.

II Overview

[0057] The invention provides for an aerobic in-vessel digestion system particularly suited to the accelerated digestion of organic waste material from commercial operations such as, for example, restaurants, institutions (schools, hospitals) food stores and the like. This invention provides several advantages over prior solutions. The composting system is capable of operating efficiently and with minimal preventative maintenance and is designed to minimize potential malfunctions by reducing the number of moving parts (particularly enclosed moving parts, which are more costly to service).

[0058] The invention comprises an apparatus and process and system essentially used for the production of compost from organic waste material. Micro-organisms, such as bacteria, mold fungi, protozoa, nematodes or actinomycetes participate in the composting process, and the aerobic decomposition produces a highly usable compost material.

[0059] Decomposition or rotting depends essentially on the oxygen content, water content, C/N nutrient content, temperature and pH of the material to be converted. With a sufficient air supply, this process proceeds virtually without odors, in particular, at temperatures of 60 to 90 on average.

[0060] The present invention provides an apparatus in which optimal operation within the composting chamber is best at or near full. There is no turning or mixing or complex parts required to achieve such turning and mixing. No augers or mixers are necessary in the actual composting chamber. One key aspect of the invention is that a mass of organic material (shredded from pre-processing) is simply fed into the chamber via a plurality of spaced/interspersed top entry portals. Feeding at each portal is preferably alternating (at intervals) so the mass of shredded organic material is interspersed substantially equally across the chamber. By gravity and aerobic processing, along with the removal of fully processed material from the bottom of the chamber, mass moves from the top to bottom of the chamber naturally and in a vertically more consistent and uniform manner due to the multiple entry portals.

[0061] The present invention provides a sealed composting chamber which is aerated. Aeration accelerates drying. Bacteria used in composting process create heat which further accelerates drying under these closed, controlled conditions. One key operational aspect, which the design of the present apparatus achieves well, is the maintenance of aerobic conditions (balance of oxygen, heat and bacteria viability). Processed organic material, within the enclosed composting chamber, sinks from the spaced-apart top entry portals. Newly in-fed organic material sits at the top, above the more advanced processed material. The apparatus reduces volume of organic material under aerobic conditions (hence, no smell, a reduction in pests and animals, etc. . . . ).

[0062] The present invention provides, in one aspect, a system for converting organic waste into compost comprising:

a) a hopper for receiving raw organic waste comprising a lid, openable during raw organic waste tipping and closable;
b) an organic waste conveyance means for delivery of the raw organic waste from the hopper to a shredder;
c) a shredder for resizing the raw organic waste to a selected, desired reduced particle size, to form shredded organic waste;
d) an intermediary delivery container for collecting the shredded organic waste;
e) a composting unit comprising an enclosable composting chamber comprising a top, a bottom, a first end, a second end and two opposing sides, wherein the composting chamber comprises, on its top surface, a plurality of spaced, closable, organic matter waste entry portals and also comprises, at the bottom of the composting chamber, at least one compost exit portal;
f) a delivery means to align the intermediary delivery container with each of the entry portals on the top surface of the compositing unit;
g) a sealable collection chamber disposed under the composting chamber, aligning with the compost exit portal, said collection chamber comprising at, at least one end thereof, a door for access therein;
h) a collection bin of a size and dimension to fit entirely within the collection chamber and removable therefrom when full of compost;
i) an air supply means for introducing controlled air into the composting chamber to aid in the decomposition of the organic material, comprising blowers and appropriate piping/ducting;
j) a rotating gate between the compost exit portal and the collection chamber providing intermittent closing the of the composting chamber and opening of the compositing chamber for transference of compost from the composting chamber to the collection bin there below; and
k) a biofilter to mitigate odours and emissions from the processing chamber by the air supply system.

[0063] More specifically, the enclosable composting chamber comprises a top, a bottom, a first end, a second end and two opposing sides. The composting chamber comprises, on its top surface, a plurality of spaced closable, organic matter waste entry portals and also comprises, at the bottom of the composting chamber, at least one compost exit portal. The spaced closable, organic matter waste entry portals are removably matable with a delivery vehicle or delivery container for the transfer of shredded organic waste therethrough and into said chamber. The compost exit portal is aligned with a sealable collection chamber disposed under the composting chamber, and the compost exit portal comprises a rotating gate enabling intermittent closing of the composting chamber and opening of the compositing chamber for transference of compost from the composting chamber to the collection chamber there below.

[0064] Preferably, the hopper for receiving raw organic waste comprises an opening at or near ground level for receiving raw organic matter from a transport means, such as a truck. In another aspect, a ramp is aligned with an opening of the hopper such that a truck or transport means carrying the raw organize waste simply drives up the ramp to more easily deposit the load into the open hopper. In one aspect, a hopper pit is below ground level.

[0065] Preferably, an organic waste conveyance means delivers the raw organic waste from the hopper to a shredder or chipper, adjacent to the hopper. All new organic material is fed through this shredder or chipper prior to feeding into the composting chamber so that surface area of particulates is increased for drying. Most preferably, the raw organic waste is shredded into a particle size no larger than one cubic inch. Preferably, the shredder is a material shredder/particle size reducer powered by a electric motor that provides low speed, high torque counter-rotating cutters that intensively shear and shred. The tooth size, blade size, and spacing of the shredder are calculated to tear and shred the supplied raw organic matter into particles not larger than 1 cubic inch. The shredder is capable of handling the all food scraps, including bones, as well as supplemental bulk materials. Preferred conveyance means to the shredder, from the hopper, include augers and conveyer belts.

[0066] After shredding of the raw organic material or feedstock to the optimal size, it is required to convey it to at least one entry port within the compost chamber for subsequent aerobic digestion within the chamber, then off-loading through the bottom exit portal. The high internal temperatures inside of the chamber generally vaporize water in the organic matter that is exhausted via a combination of enforced aeration and an exhaust vent. The system of the invention enables continuous input of feedstock, at alternating entry ports at the top of the chamber. Preferably, there is provided in alignment with the shredder, a tote dock, into which the tote is engaged during filling of the shredded organic matter from the shredder.

[0067] Another key aspect of the invention is the provision of a delivery means to align the intermediary delivery container with each of the entry portals on the top surface of the compositing unit. In one aspect, this may be achieved by use of a container or tote for collecting the shredded organic waste and then transferring the organic waste to one of the selected entry portals. It is to be understood that the tote collection and transfer to the selected portal may be fully automated as long as after filling of the tote, alternating portals are used for entry and conveyance of material into the chamber. However, within the present invention, the delivery means to align the intermediary delivery container with the docking stations at the entry portals on the top surface of the compositing unit may be achieved by other means including conveyer belts/assemblies and chutes (with conveyance by gravity or by mechanical means). If totes or containers are used, they may be moved by hydraulic lifts, forklifts or other appropriate material transfer devices, apparatus and machines.

[0068] In one aspect of the invention, the rotating gate comprises a sensor for tallying the number of open-shut gate rotations and there is a means to feedback the tally to a controller, said controller controlling organic matter feed intake at the organic matter entry port. The controller may additionally and preferably provide automatic feedback to the delivery means, such that a reaction-conditions optimal amount of organic waste is delivered to a desired entry portal, at a desired time in order to maintain optimal biochemical processing conditions.

[0069] Preferably, the composting unit comprising an enclosable composting chamber with a top, a bottom, a first end, a second end and two opposing sides, wherein the composting chamber comprises, on its top surface, a plurality of spaced, closable, organic matter waste entry portals and also comprises, at the bottom of the composting chamber, at least one compost exit portal. Within the context of the invention, multiple or plurality of entry portals preferably means greater than two. There may be three entry portals. There may be four entry portals. The specific number of portals depends of on the size the of entire chamber. In a preferred aspect, each portal is equally dispersed from all others. In one aspect of the invention, the portals are staggered i.e. not in alignment across the top of the chamber. The composting chamber is preferably fabricated of stainless steel although it could be made of any suitable material which does not adversely affect the composting process.

[0070] In a preferred aspect, there is provided a tote docking station above each entry port on the chamber, such station being engagable with the tote and to secure tote in position during emptying of contents into the chamber, via the entry port. In a preferred aspect the tote is filled through an open top while in position in the tote dock, under the shredder. The tote is then conveyed into a position of removable engagement with a tote docking station at which time either a bottom door of the tote opens or an aperture within the bottom surface of the tote opens to release contents into the chamber. It is optional that the top of the tote comprises a lid.

[0071] Particle size is an important aspect of the composting process. If the waste particles are too large, the relatively small ratio of surface area to mass inhibits the start of the process. Shredding the material prior to input in the composting chamber offers a large advantage in this respect. On the other hand, if the input material is shred too small, porosity and the ability of the material to be aerated is greatly diminished. As a result, bacteria is less able to act. An optimal particle size may be considered to be about 3 cubic inches. A shredder in the infeed stage provides for this requirement.

[0072] Preferably, the shredder reduces the material into particles of not more than one by one by three inches, the maximum size calculated to facilitate efficient and complete composting in accordance with the process and apparatus of the invention. Particles larger than about four cubic inches (while workable) begin to reduce the speed and effectiveness of the bacterial action. Smaller is generally better.

There is provided FIG. 1 a side view of a intake system 10 showing the entire intake unit for raw organic matter, comprising a hopper 20 for receiving raw organic waste comprising a lid 22, openable during raw organic waste tipping and closable; an organic waste conveyance means 26 for delivery of the raw organic waste from the hopper 20 to a shredder 28; and shredder 28 for resizing the raw organic waste to a selected, desired reduced particle size, to form shredded organic waste.

The apparatus is operated (preferably and optimally) at a level which is at least 90% full. In one aspect, a light sensor across the width of the composting unit/chamber near the freshly chipped green (organic) waste detects when the composting chamber is full. [0109] 6. In a preferred aspect, two blowers continuously inject air up through the bed of the composting unit/chamber. Air is vented out of the top of the composting unit/chamber. The maximum rate of air flow is limited by the availability of single phase electricity to power the blower, nominally 5 hp. [0110] 7. Activated by a light sensor, a rotary 4 paddle gate at the bottom of the chamber rotates in 90 increments (to minimize intrusion of rats into the composting chamber) until the light sensor at the top of the composting chamber detects that there is again room for more green waste adjacent to the chipper. [0111] 8. A counter on the rotary gate indicates the number of gate rotations and hence the amount of composted and dried green waste that should have dropped into the underlying 2064 (18 m3 or 640 ft3) height roll-off collection bin, within the collection chamber. The counter may be calibrated to read % Full so a user knows when to replace the collection bin. In one aspect, a maximum weight of material in the collection bin is 6 tones. This is of course variable depending on the size of the collection bin. [0112] 9. When the collection bin is full of dried and composted green waste (the compost), the collection chamber door or doors are opened and the bin is removed from the length of apparatus and is hauled away. A new collection bin is pushed under the apparatus, within the collection chamber to again collect dried and composted waste, enabling a continually operating process.

[0113] The collection bin is housed in a sealed collection chamber, in part, so rats and other pests cannot feed at the collection bin. When the collection bin is to be changed out, end doors are opened. When the collection bin is replaced, the end doors are closed.

Process:

[0114] The present invention provides a process for composting organic material comprising the steps of:

(a) shredding raw organic material a selected, desired reduced particle size, to form shredded organic waste;
(b) delivering shredded raw organic waste to a first entry portal at the top of a composting unit, wherein said composting unit comprises a composting chamber with a plurality of spaced, closable, organic matter waste entry portals on its top surface and also comprises, at the bottom of the composting chamber, at least one compost exit portal;
(c) incubating the shredded raw organic waste within the composting chamber until shredded raw organic waste is composted and by gravity falls to the bottom of the composting chamber;
(d) as needed to maintain composting chamber at or near full for optimal composting, delivering further shredded raw organic waste to a second entry portal on the top of the composting chamber;
(e) as needed to maintain composting chamber at or near full for optimal composting, delivering further shredded raw organic waste to a second entry portal on the top of the composting chamber;
(f) collecting gravity moved processed compost from compost exit portal.

[0115] In a preferred aspect, the process additionally provides the step of sensoring monitoring fill level of composting chamber to ensure operation at or near full and to trigger further fill at one or more of one entry portal at the top of a composting chamber.

[0116] In a preferred aspect, the process additionally provides the step of sensoring order of fill of each entry portal at the top of a composting chamber to ensure that composting chamber is uniformly filled across top.

[0117] In a preferred aspect, as needed to maintain composting chamber at or near full for optimal composting, the process provides for delivering further shredded raw organic waste to a third entry portal on the top of the composting chamber.

[0118] In a preferred aspect, as needed to maintain composting chamber at or near full for optimal composting, the process provides for delivering further shredded raw organic waste to a fourth entry portal on the top of the composting chamber.

[0119] In a preferred aspect, as needed to maintain composting chamber at or near full for optimal composting, the process provides for delivering further shredded raw organic waste to a additional entry portals on the top of the composting chamber.

[0120] In one aspect, no two adjacent entry portals on the top of the composting chamber are sequentially filled in order to ensure a uniform fill level of shredded raw organic waste across the top interior of the composting chamber.

[0121] In one aspect, a sensor directs and operates the opening of rotary exit gate at the bottom of the composting chamber.

[0122] In one aspect, shredded raw organic waste is delivered to each entry portal at the top of a composting unit by a conveyancing means, which is positionable and alignable with each entry portal. In one embodiment, this may be achieved by a delivery means aligning an intermediary delivery container or tote with an entry portal on the top surface of the compositing unit. This alignment is generally with one entry portal at a time although in some circumstances, for optimal fill efficiency, such alignment may be with two or more entry portals at a time.
