In embodiments, the pump 40 can be a 5 horsepower pump or other appropriate pump 40 known in the art. The pump 40 can be adapted to extract oil from the cooking oil reservoir 20 into filtering pan 30. In some configurations, the pump 40 is adapted to extract oil from the cooking oil reservoir 20 and/or the filtering pan 30 into the pump 40.
(19) The system 1 can include a pump inlet 48 connected to the pump 40. The pump inlet 48 can be adapted to facilitate fluid communication with the interior of the pump 40. The pump inlet 48 can, in some configurations, be accessed via an intake port 41 from outside of the housing 10. In some embodiments, the intake port 41 is connected to an intake hose 49 or other fluid conduit. The intake hose 49 can be removably connected to the filtering pan 30. In some embodiments, the intake hose 49 provides fluid communication between the pump inlet 48 and the filtering pan 30. In some embodiments, the intake hose 49 can be used to create fluid communication between the pump inlet 48 and the cooking oil reservoir 20. The cooking oil reservoir 20 can include a drain 22. The drain 22 can be used to transfer oil or other fluids from the cooking oil reservoir 20 into the filtering pan 30. In some embodiments, the intake hose 49 is adapted to mate with the drain 22 and provide fluid communication between the cooking oil reservoir 20 and the pump inlet 48.
(20) In some embodiments, the system 1 includes an pump outlet 42 connected to the pump 40. The pump outlet 42 can be adapted to facilitate fluid communication with the interior of the pump 40. In some embodiments, a valve 90 is connected to the pump outlet 42. The valve 90 can be adapted to facilitate selective communication between the pump outlet 42 and one or more outlet channels. In some embodiments, the valve 90 is a three-way valve (e.g., a three-way ball valve). The outlet channels of the system 1 can include a storing channel 46 and/or a reuse channel 44.
(21) The valve 90 can be adapted to transition between a reuse orientation and a storing orientation. When in the reuse orientation, the valve 90 can provide fluid communication between the pump outlet 42 and the reuse channel 44. In some embodiments, the system 1 includes an outlet port 47 that can be accessed from outside of the housing 10. The system 1 can include an outlet hose 45 adapted to connect to the outlet port 47.

(27)
(28) In some embodiments, the housing 10 can include one or more transport features on the bottom of the housing 10. For example, the housing 10 can have attached wheels that allow for easier transport of the housing 10 from one location to another. In some embodiments, the housing 10 includes one or more transport features adapted to engage with a hand truck, forklift, or other transport tool.
(29) A method of using the system 1 can include using the drain 22 to transfer cooking oil from the cooking oil reservoir 20 to the filtering pan 30. The method can further include using the filtering pan 30 to filter at least some particulates from the transferred cooking oil. The user of the system can then decide whether to return the filtered cooking oil to the cooking oil reservoir 20 or to the storage tank 70. Upon deciding to transfer the filtered cooking oil to the storage tank 70, the user of the system 1 can insert the spout 64 or other end feature of the intake hose 49 into the filtering pan 30. In some configurations, the user can then transition the valve 90 to the storing orientation. The user can also transition the pump actuator 12 to the activation position. Transition of the actuator 12 to the activation position can power the pump 40. In some embodiments, powering the pump 40 facilitates transfer of cooking oil from the filtering pan 30 to the storage tank 70 via the intake hose 49, the pump 40, the pump outlet 42, and the storing channel 46.
(30) In some embodiments, the user can transfer the used cooking oil from the filtering pan 30 to the storage tank 20 via the outlet hose 45. In some such embodiments, the valve 90 can be set to the reuse orientation and the spout 64 or other end feature of the outlet hose 45 can be inserted into the storage tank 70, as illustrated in
(31) On the other hand, the user can decide to transfer the filtered cooking oil back into the cooking oil reservoir 20. In some such scenarios, the user can insert the spout 64 or other end feature of the intake hose 49 into the filtering pan 30. Furthermore, the user can insert the spout 64 or other end feature of the outlet hose 45 into the cooking oil reservoir 20. The user can then transition the valve 90 to the reuse orientation. Upon transition of the actuator 12 to the activation position, the pump 40 can facilitate transfer of cooking oil from the filtering pan 30 to the cooking oil reservoir 20 via the intake hose 49, the pump 40, and the outlet hose 45.
(32) In some embodiments, the user can transfer used cooking oil from the storage tank 70 to a disposal location. For example, the spout 64 or other end feature of the intake hose 49 can be inserted into the storage tank 70 via the lid 72 or some other access point. The spout 64 or other end feature of the outlet hose 45 can be inserted into the desired disposal location. Upon transition of the actuator 12 to the activation position, the pump 40 can facilitate transfer of cooking oil from the storage tank 70 to the disposal location via the intake hose 49, the pump 40, and the outlet hose 45.

(35) More specifically, as shown in
(36) As is also shown, the main housing 202 may also include handles 280 to facilitate moving the receptacle from location to location in the kitchen. The first receptacle 206 may also include a large round access opening 250 that provides access to the reservoir 70 so as to permit the used grease or cooking oil to be pumped and for removal in the manner that was described above.
(37) The main housing 202 is preferably rectangular and is sized so as to receive, in one non-limiting embodiment 78 gallons of used cooking oil or grease, however, it will be appreciated that the main housing and system 200 can be scaled depending upon need. The main housing 202 defines a shelf 212 that extends outward from the first receptacle 206 that is sized to receive a course filter 214 and a fine filter 216.
(38) More specifically, the course filter 214 includes a housing 215 that is attached to a first side 217 of the first receptacle 206 so as to be somewhat elevated above the shelf 212. The bottom surface 219 of the course filter housing 215 has a drain hole 221 that is coupled to the pump system 70. The course filter 214 includes a course filter screen 222 that filters large particulate matter from used cooking grease and a support member 226. The course filter housing also includes a top surface 224 that defines an opening 230 which, in this embodiment, comprises a square 44 inch opening. The opening 230 preferably has raised lips 232. A user who is recycling or cleaning grease or cooking oil can insert a hose from a fryer 20 into the opening 230 and the cooking grease and oil are then filtered by the course filter screen 222.
(39) The course filtered cooking oil or grease then falls or is sucked by the pump system 40 to the bottom of the course filter housing 215 where it is then pumped into a fine filter housing 216 that is positioned adjacent the course filter housing 215 on the shelf 212. The fine filter housing 216 is generally the same shape as the course filter housing 215 but is, however, larger as the filtration member positioned therein comprises a microfilter 240 that filters the cooking oil or grease more slowly and, thus, requires more volume.
(40) In this embodiment, the pump 70 is attached to hoses and/or pipes such that cooking oil or grease from the bottom of the course filter housing 215 is then pumped into the top of the fine filter housing 216 so as to percolate through the fine filter 240 into the bottom of the fine filter housing 216. The finely filtered grease can then either be pumped back to the frying via a hose out 45 (See,
(41)
(42) The first receptacle 206 may include two openings at the upper surface 266, one for permitting access to the reservoir 70 for removing stored grease and one, possibly, for accessing a secondary reservoir for storing cleaned or unused grease or cooking oil. It will be appreciated that he configuration of the housing 206 and the reservoirs contained therein can vary without departing from the spirit if the present invention. In one implementation, the housing can house a 58 gallon or cubic inch reservoir. The grease can also be pumped into a holding tank in one implementation.
(43) Referring now to
(44) As shown in
(45) In this implementation, the housing 302 can also house a pump and valve assembly 320 that is similar to the pump and valve assembly described above. In this implementation, the pump and valve assembly includes a 5.8 gallon per minute roller pump with a house power 120 volt motor and the valve assembly comprises 4 ball valves with electrical activation. The combination of the pump and valves in the assembly 320 permits the smart control of the flow of cooking oil via user activation of a touch screen/display 330 through the use of a computerized control system 350. The various tanks of the system 300 can also include recessed sight glass windows so that visual verification of the levels of the tanks can also be done.
(46) As shown in
(47) Referring now to
(48) In this embodiment, the user via the user inputs can control the pump and valve system 320 to perform the following operations. Oil can be taken from the cooling location via the want 317 into the filtering system 314/340 and this oil can then be returned via the wand 317 to the cooking location. This allows for oil to be easily filtered and then provided back to the cooking equipment.
(49) Alternatively, oil from the cooking location can be extracted by the wand 317 and then provided to the storage tank 304 for subsequent disposal. Disposal of used oil in the storage tank 304 can be done either by pumping the oil out via the wand 317 or a separate discharge nozzle 352 can be used to remove the oil from the storage tank 304 in a container for transport to off-site storage 354. The pump system 320 can also take oil out of the storage tank 304 and run it through the filtering system 314/340 although it is contemplated that oil that is stored in the storage tank 304 is generally used oil that is sufficient used that it is being stored for disposal and replacement. As is also shown in
(50) As is also shown in
(51) Further, as shown, the control system 320 can also include a known communications system such as an internet or intranet based wireless system that allows for the storage volume, oil dispensed volume, temperature, filtration time and frequency to be transmitted remotely. This information can be transmitted to a remote location 366 which can include an office or headquarters for the restaurant. Further, the control system 350 or a functionality of the remote location 366 can also be implemented whereby the oil collection company is notified when there is sufficient oil in the storage tank 304 to warrant collection of the oil.
(52)
(53) The system therefore provides for a more controllable oil storage and filtration system. The system is smart in that it can monitor parameters that the cook staff may be too busy to monitor or insufficiently knowledgeable to monitor. The system also allows for either manual operation of the pumping or, in some instances, the operation could be automated at pre-planned intervals or when the sensed parameters suggesting filtering or pumping of oil is needed.
(54) While the aforementioned description has shown, illustrated and described various systems and methods of implementing the present invention, it will be apparent that various substitutions, modifications, and changes to the implementation of these systems and methods can be made by a person of ordinary skill in the art without departing from the teachings of the present invention. Hence, the present invention should not be limited in scope to the foregoing description but should be afforded the full scope of the equivalents and changes understood by a person of ordinary skill in the art.
