PROCESS FOR PRODUCING HYDRO-MULCH COMPOSITION FROM MUCK

Abstract

A combination of mulch and sterilized organic fertilizer is provided for hydro seeding and hydro-mulching for seed establishment and erosion control. The composition includes hammer milled straw, horse manure and urine, sterilized with heat and processed to provide an optimal particle size. The incorporation of horse manure utilizes a dispersible natural fertilizer collected and processed within a certain time frame which provides an efficient method of recycling green horse manure and liquid waste having a higher acidity than decomposed animal waste. Tackifiers and flocculants such as ground paper aid pumpability and help tack the straw fibers to the ground. The equipment includes a gas heat source, a dryer vessel and a processing unit. The dryer vessel receives the bedding composed of straw and manure for contact with the heated gases to convert the same to a sterilized dry material.

[0052] Horse stall waste comprising a major amount of straw mixed with a minor amount of horse manure and liquid waste is utilized as a feed material to product a hydro-mulch for hydro-seeding and hydromulching to establish seed beds and control erosion. The product is mixed with water and sprayed over bare ground with seed and optionally a chemical fertilizer in a slurry to establish ground cover whereby the fracture straw fibers and provide shade to seedlings and retain moisture affording a transfer mechanism of the fertilizer to the soil at a slow rate as compared to conventional straw cover. A tackifier such as guar or other water soluble polymer is often used in addition to a flocculent such a polyacrylamide to enhance pumpability and aid in tacking the straw fibers to the ground and each other. The preparation process utilizes a tower dryer having series of shelves and rotating cylinders increasing retention and residence time of the feed mulch material in the dryer which subjects the feed material to dry air at a temperature of about 200 to 350 F. for up to 10 minutes and preferably from about 3 to 5 minutes to control humidity of the product. A novel feature of the process is the ability to utilized fresh or green horse manure waste having a high moisture content as an organic fertilizer in a hydro-mulch product which adds nutrients to the ground and provides a means to reduce the amount of chemical fertilizer used for ground cover operations.

Process:

[0053] Wheat straw or other cereal grain straw, such as a oat straw and/or a wheat straw and/or a rye straw and/or a barley straw comprise the majority of the fiber material; however, the bedding material may also contain a minor amount of or any other fibrous plant based material including a flax and/or a hemp and/or a sawdust and/or a paper is typically used for bedding material in the horse industry as well as for other domestic animals including cattle and sheep and for wild animals in zoos and animal habitats. The mixture of waste materials from the animals including manure and urine is collected after becoming saturated with waste and is delivered to the processing plant in walking floor trailers where it is stored in bulk for pneumatic conveyance into a feed system.

[0054] As shown in FIG. 1, the bulk feed is fed into the pneumatic conveying system via a live floor feed and break-up mechanism 12 wherein the muck feed 7 is picked up into conveyance air stream and rocks, debris, and other heavy unwanted material is removed via a belt for disposal. Counter rotating spiked beaters 14 break up the much for delivery into the hot air stream and a high speed belt 15 moves the material to a hot box 16 where the feed system conveys the material through a vacuum line which enters a heated air stream. At about 3500 to 4500 feet per second material is delivered to the next stage where the feed material is subject to a 4 million BTU gas fired burner 18. The burner 18 heats the air up to 450 F. and the feed material as it is pneumatically conveyed into the air stream. The burner develops consistent heat of 250 F. to 450 F. for proper decontamination and sterilization of the microorganisms and seeds in the feed material. These temperature ranges also ensure proper break down of the lignins of the material. As shown in the drawings in FIGS. 2 and 11, a plurality of variable speed rotary air locks 319 are used throughout the blower and vacuum conveying system to control the rate of feed.

[0055] As best depicted by the flow diagram in FIG. 2, the horse muck bedding and straw is delivered in walking floor trailers to a feed system having a live floor feed and break-up mechanism 12 including beaters 14 to break up the material which is moved via conveyors 15 to be fed into the pneumatic conveying system. A burner 18 provides the heated air as material is pneumatically conveyed through the drying system. A cyclone removes the moist air and conveys the material to a first cyclone 20 allows moisture and spent air to escape while material collects into a feed control box 22 which feeds material at a consistent feed rate into the hot air stream for processing at a selected residence time through a dryer 24 or dryer box such as a shelf dryer, collider dryer, fountain dryer, or WALKER dryer which includes a rotary cylinders and shelf drying arrangement. Selection of the dryer such as the WALKER dryer is considered an important and novel feature of the process, for the heated material is suspended in a hot air stream at 3500 to 4500 fps as it is conveyed to the dryer achieving a temperature in the dryer of 350 to 400 F. which heats the seeds to at least 200 F. for a selected period of time (usually 3-5 minutes per dryer), which kills any seeds to prevent germination and sterilized the organic product. Sufficient heat is supplied by the dryers wherein each one can be heated to a selected temperature for a selected residence time to provide an effective means to kill any seeds and sterilize the muck product. One to three dryers may be used, preferably at least two depending upon the feed rate and size of the dryer. It takes less time to heat and prepare a product for baling having straw lengths up to 10 inches than a hydro-mulch product having straw lengths averaging one inch or less, and more of an inch or less and most preferably averaging about inch or less in length. The final product is composed of straw fibers some of which are shredded, pulped, crushed, and frazzled producing the maximum surface area for absorption of water. The drying process includes drying of the material for a selected residence time of from 200 to 300 F. for three to five minutes in the tower dryer conveyed through a series of shelves while the material is subjected to a fibercation and expansion process utilizing fluffing cylinders 25 for enhanced drying, fragmenting, and pulping which expands, splits and creates more fibrous particles of straw increasing the surface area for adsorption of moisture in the subsequent hydro seeding process and absorption of moisture as a ground treatment component. The product forms a superior moisture absorbing material as opposed to straw and/or paper and/or hay and/or other filler material which is crushed, ground to small particles and molded, extruded or formed into pellets or granular material having about the same dimensions.

[0056] A feed control air lock system includes a HE-60 pull fan 26 providing a source of moving hot air and material through system. Material travels through the dryer at a selected rate and volume for further drying prior to being fed to a second cyclone 30 for removal of excess moisture and spent air prior to feeding the material into a hammer mill 32.

[0057] The material is ground in the hammer mill 32 at approximately 200 F. to a selected size, preferably inch or less. The hammer mills include hammer, screens, and breaker bars or hardened material to resist wear and the abrasiveness of the material. A screen size of inch is required to provide a product with inch of size and vertically fracture the straw producing fibrous material to increase the surface area of the particles, increase absorption of moisture and expansion of the particles for application as a hydro mulch material when mixed with water and optionally a chemical fertilizer and/or optionally seed. The air handling fans are special wear fans designed to have a high rpm in order to facilitate the sizing process. The horse muck and wheat straw feed stream is dried below 10% moisture at this stage and cooled to 100 F. or less. Material is vertically fractured from the milling process for optimum performance for its intended use. At this point material, the material is environmentally friendly with a very low moisture and having a physical structure of the cellulose fibers sized and exposed for optimum performance in its intended use.

[0058] The processed muck material cooled to ambient temperature and deposited into a live floor surge bin 34 for bulk storage and transfer to stationary mixers 40 such as reel mixers 733 at the mixing stations 36 and 38. The floor surge bin is designed to deposit material as needed for mixing.

[0059] The mixing station 38 includes at least one and preferably a plurality of mixers such as reel mixers. The stationary mixers 40 are reel or ribbon mixers which include special wipers for better lifting and mixing capabilities. The mixing station includes counter rotating augers in the bottom to continue the blending of said materials while distributing them to the compression bagger or other packaging station. The mixers mix a volume of 300 cubic feet per mixer of the fibrous materials.

[0060] Mixers break up and evenly distribute multiple additives with the horse muck with straw for a consistent engineered hydro mulch with organic fertilizer material. As material is deposited into mixer other ingredients of fibrous organic nature can be blended together for particular applications and transferred to a surge bin 42. The ingredients are mixed according to weight and bulk density. The dust prevention is controlled in order to mix the ingredient without lost of specific ingredients to maintain the integrity of the mix formula.

[0061] The base horse muck composition containing processed straw, urine, and manure is transferred to containers of a desired volume or weight. For instance, the product may be distributed to a compression bagger station 44 at approximately 7.5 cubic foot of volume where the product is compressed to 2.3 cubic feet of volume and bagged in 50 pound bags ready for transport. The containers are preferably moisture proof and air tight. Moisture and mix variations are adjusted to achieve said weight for specific blends of finished products.

[0062] In some applications, the material can be filled in bags, for instance in paper bags, which are then closed or sealed by means of a paper bag sewing machine. Paper bags are pervious to air and environmentally friendly. Material filled in paper bags does not go moldy and preserves the microorganisms due to the air permeability of the paper bags. Both granulated and not granulated material can be dried and mixed in the above-mentioned drying and mixing process.

[0064] FIG. 11 is a schematic showing an alternate embodiment process flow diagram including the following major components: 310 module feeder, 311 conveyor, 312 heater, 314 hot air fan, 316 rotary air lock to control feed rate, 318 blower, 319 variable speed rotary air lock, 320 cyclone, 322 hammer mill, 324 hot air shelf dryer, 326 blower, 328 cyclone, 330 hammer mill, 332 hot air shelf dryer, 334 blower, 336 cyclone, and 338 bagger. The module feeder holds the muck and provides it to the conveyor belt. A fan pulls hot air form the hot box which is mixed with the muck and blown through an air lock which controls the feed rate to the blower which blows the material to a cyclone or cyclone/hammer mill unit to reduce the size of the straw fragments. The material is then blown to a vertical shelf dryer for a selected residence time in the dryer at a selected temperature. The material is sucked into a blower and transferred to a second cyclone and/or cyclone/hammer mill then conveyed to a second shelf dryer for a selected residence time at a selected temperature. A fan conveys the dried material to a third cyclone whereby the material is conveyed to a packaging station for bulk container storage or bagging.

Composition:

[0065] The base composition of the horse muck of the present includes wheat straw, manure and urine; however, it is contemplated that the horse could also contain some hay, sawdust or other contaminants in small amounts. The straw is typically from grain crops, such as barley, oats, or wheat. Any hay straw or wood chips in the muck would be considered a contaminant rendering the composition less effective.

[0066] The wheat straw typically contains 13% nitrogen, 3.3% phosphorous, and 23% potassium. The horse muck typically contains 14.9% nitrogen, 45% phosphorus, and 13.2% potassium. One ton of straw horse muck contains: 1600 pounds of H2O, 10 pounds of nitrogen, 5 pounds of phosphorus, 101 lbs of potassium. Horse urine contains 3 pounds of nitrogen, and 3 pounds of potassium. According to an assay sample from Ohio State University, the horse muck sample contained 70.8% water, 0.51% nitrogen, 0.21% phosphorus, and 0.68 to 0.90% potassium. A 1000 pound horse makes 50 pounds of manure a day and 10 pounds of urine a day which equates to 20 pounds of soiled bedding (muck) a day. The density of the wheat straw is 2.5 pounds per cubic foot which has a capacity to absorb 2.2 pounds per 20 pounds of straw.

[0067] Usually about 100-150 pounds of straw is used to absorb about 60 pounds of animal waste a day. Thus, the content of the waste products in the straw will vary, but typically muck will contain from 0.1 up to 20% by wt. organic manure waste, more preferably from 0.2 to 15% by weight organic manure waste, more preferable from about 0.3 to 10% by weight organic manure waste, and more preferably from 0.1 to 5% by weight organic manure waste, and 80 to 95 percent straw. Upon drying the final hydro-mulch product typically contains about 95 to 99 wt. % straw but depending upon the application, the muck product may contain 0.1 to 5 wt. % dried waste material and 95 to 99.9 wt. % straw or other natural fibrous material.

[0068] Treatment of the horse muck according to the process described herein pulverizes and fragments the straw increasing the surface area and adsorption area of the straw particles allowing longer straw particles up to inch long to be used which forms a bridge between the straw and paper particles upon deposition on the ground surface to be treated as compared to the conventional hydro mulch using straw particles of a smaller size of about inch because the straw is processed with using conventional equipment which mixes but does not fragment or pulp the straw segments.

[0069] Pre-ground additives of shredded or pulped paper, and/or wood shavings, and/or cotton may optionally be added to the horse muck composition, but is not necessary.

[0070] Paper can be added to the processed horse muck in the mixing stage as shown in FIG. 3 in an effective amount to retain water in the composition to form a slurry for spreading the hydro-mulch composition by pumping the composition onto the surface to be treated. The paper is usually ground into small particles of less than inch and preferably even smaller and mixed with the horse muck composition. The paper holds the water to hold the horse muck straw mixture into a slurry solution better than a horse muck solution using straw alone because the water does not remain in solution with the straw to form as stable a solution for pumping as when the mixture contains from 0 up to 30% by weight paper, and typically from 20-30% paper.

[0071] Wood fibers or shavings which have been subjected to defragmentation to pulverize the wood forming expanded fibrous fragments may also be added to the horse muck composition in an amount of from 0 up to 30% by weight and preferably from 10-20% instead of or in addition to the paper. The material once processed by physical reduction and/or steam resembles fuzz or a stringy material.

[0072] Cotton may also be used together with wood or paper or instead of same in an amount up to 30% by weight, but less than 10% and more preferably at about 5% in combination with the horse muck and or paper.

[0073] A Tackifiers such as a guar and/or polyacrylic compound may be used to hold the particles together upon application to the ground to prevent washing. The tackifier is usually an organic tackifier such as guar, or starch based tackifier or other water soluble polymers. The tackifier acts as a glue to hold the material together. The amount used is dependent upon the slope of the ground to be covered and may vary from 0 up to 10% by weight and more preferably from 2.5 to 7.5%, and most preferably from 5 to 7 percent.

[0074] Surfactant up to 1% by weight may also be used to enhance wettability of the paper.

[0075] One preferred embodiment contains 100% processed muck and more preferably from 25 to 85 percent processed muck, and more preferably from 50 to 75% processed muck; up to 30 percent paper; and from about 0.5 to 10% tackifiers.

[0076] A selected amount of seed, alfalfa meal or peat compost may be added to the horse muck composition or base composition with other selected ingredients to provide a soil replacement composition for treatment of ground which lacks a soil component to grow plants such as clay.

Example 1

[0077] A slightly acidic hydro-mulch composition is formed comprising or consisting of or consisting essentially of a major amount of a straw selected from the group consisting of barley straw, oat straw, wheat straw, and combinations thereof mixed with organic waste material comprising at least a minor amount manure and a horse muck consisting of 80 to 99.9 wt % and more preferably 90 to 99 wt. % straw and fibrous material and from 0.1 to 20 wt. % and more preferably from about 1 to 10 Wt. % of urine and animal manure, primarily horse manure having a higher acid content than decomposed horse manure.

[0078] The process for producing a hydro-mulch composition from muck comprising at least a major amount of straw and at least a minor amount of organic manure waste, comprising the following steps.

[0079] Muck feed material is placed onto a live floor conveyor and screening the muck feed material to remove debris. The muck feed material is fed into an apparatus having rotating beaters for breaking up the muck feed material into smaller particles capable of transfer via a air conveyance system and heated to with hot air to about 450 F. with hot air created by a burner comprising a 4,000,000 BTU gas furnace. The hot air is blown into a hot box and the mechanically conveying a selected volume of smaller particles of muck material is fed through the hot box on a conveyor at a selected rate of speed for a selected amount of time. The material is pneumatically conveyed at about 35400 to 4500 feet per second with a hot air stream of 250 to 450 F. to a first dryer to remove moist air. The material exiting the dryer is conveyed in a hot air stream with a first cyclone which allows moisture and spent air to escape while material collects into a feed control box there below. The temperature and residence time of the muck feed material is exposed to a hot air stream is controlled with a control apparatus controlling temperature, air flow, and feed flow via an air lock control system. A pull fan provides air flow movement of the heated air with the muck feed material and conveyance to a dryer box for drying the muck feed material at a selected conveyance rate for a selected time for a selected temperature. The dryer box comprises a shelf dryer, a collider, a fountain dryer, or a Walker dryer. The preferred Walker dryer incorporates fluffing cylinders whereby heated material suspended in a hot air stream at 3500 to 4500 fps arrives at the dryer at about 350 to 400 F. and is fluffing cylinders rotate to break up the material within the dryer to improve surface area and dryer efficiency. The remaining moisture and spent air from the muck feed material is removed with a second cyclone whereby material collects into a feed control box there below and fed to a size reducing apparatus such as a hammer mill having a screen size of inch in order to produce fibers averaging a length of inch or less and vertically fractured fragments producing a hydro-mulch product of a selected size and product of between 8 to 15% moisture and more preferably about 10% moisture.

[0080] The process optionally further comprises the steps of mixing the hydro-mulch product with a selected amount of natural fiber containing material to obtain a hydro-mulch product including a selected amount of organic manure waste, a selected amount of straw, and a selected amount of natural filler fiber material comprising a straw, a paper, a wood sawdust, a cotton, a peat, a compost material, an alfalfa meal, a hemp, and combinations thereof.

[0081] The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modification will become obvious to those skilled in the art upon reading this disclosure and may be made upon departing from the spirit of the invention and scope of the appended claims. Accordingly, this invention is not intended to be limited by the specific exemplification presented herein above. Rather, what is intended to be covered is within the spirit and scope of the appended claims.
