     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a system for handling edible oils and other fluids and, particularly, to a system for distributing, filtering, storing, recovering and disposing of edible oils or other fluids, often while in a hot condition, used in open-top vat type vessels such as fryers, cookers, and related equipment widely used in commercial or institutional food preparation establishments. 
     2. General Background 
     Today&#39;s high volume food preparation establishments commonly use commercial cooking vats, the majority of which are deep fat fryers using cooking oil or solid shortening. The cooking oil and/or shortening products are held in many individual containers, usually from 35 pound plastic jugs encased in cardboard cartons, to 50 pound blocks of solid shortening in plastic wrapping enclosed in a cardboard box. The cardboard cartons and cardboard boxes are stored indoors, taking valuable space and creating an extremely volatile situation in the case of fire. They also occupy storage space when empty until they can be put into a dumpster and hauledoff. 
     The cardboard cartons and/or cardboard boxes are manually carried into the storeroom, stacked and manually transferred to and from the vats where they are manually lifted to waist height or higher to fill the cooking vats. Personnel frequently suffer sprains and back injuries when handling the cardboard cartons and/or cardboard boxes. Additionally, food absorbs oil during the cooking process whereby oil or solid shortening must be continually added to the hot oil or liquified shortening. This is a dangerous process resulting in spattering and splashes, particularly when chunks of solid shortening are dropped in the hot liquid. When 50 pound blocks of solid shortening are used, the blocks must be melted very slowly at a low heat to prevent a grease fire when the vats are filled. However, if a grease fire occurs, automatic fire suppressors flood the vats with chemicals, thereby causing a loss of all the oil or shortening. The cooking station must be shut down and cleaned up causing a loss of revenue. 
     Adding oil frequently results in spillage loss and creates opportunities for slips and falls next to open vats having oil heated to 340 to 375 degrees. Burns are commonplace in high volume food preparation establishments some of which lead to permanent disfigurement and disability. 
     When food is cooked, the oil quickly becomes fouled with bits of food, batter, breading seasonings, etc. The particles continue to overcook, becoming burned and scorched, thereby degrading the taste and quality of the food and reducing the useful life of the oil. To avoid this situation, it is desirable to filter out as many of these particles as is practical. 
     Operations that do not filter must throw away large amounts of oil continuously. However, to filter safely, the hot oil should be allowed to cool down to a safe temperature. Cooling of the oil can take from one to several hours, requiring the fry vat to be off-line whereby no income is produced. Most operations try to get back on line quicker, risking the hazards of drawing off hot splashing oil into low, open containers sitting under foot in busy work areas. Although dangerous, it occurs as a normal part of the business. Furthermore, often late at night, near closing time, an employee picks up hot metal pots or buckets full of scalding oil and stumbles out back on multiple trips through dim lighting to a fat disposal tank to dispose of the hot spent oil. To say the least, this is a hazardous situation that needs improving even more than the oil filtering process which is another risky oil handling process that occurs in several ways. 
     One of the most commonly used filtering process uses mechanical filters receiving oil from the vat drain spout directly into a large open tub. Typically a filtering screen sits in the bottom of the tub, drawing oil through the screen, up a vertical pipe having a pump and motor mounted atop, and discharges the filtered oil via a short length hose and nozzle back into the vat. Dragging the assembly from vat to vat and the lengthy wait required for the unit to cool down so that the motor, pump, pickup tube, screen and other parts can be disassembled and removed for cleansing before the sediment and debris can be manually scooped from the tub are just some of the disadvantages. Furthermore, there are problems of sanitation and storage of a large, greasy, open tub and bulky mechanical components required for the filtering process. After cleaning the sludge, sediment and residual waste, the oil is manually disposed. The disposed of oil is picked up by scrap oil dealers, some of which charge for the removal service, others may pay a small amount for the disposed spent oil. Once removed, the waste oil is out of mind with little concern for what happens to it. There have been instances, as in one case, where the removal company simply dumped the oil over acres of ground, thereby contaminating ground water and threatening an adjacent aquifer system. It is apparent that a comprehensive overall system is needed to prevent such environmental catastrophes. 
     Several filtering devices and systems for handling of bulk edible oil have been patented. 
     U.S. Pat. No. 4,462,915 is directed to an edible oil handling system wherein the unit sits down in the fry vat only as deep as the heat tubes passing at mid-height through the fry vat oil. Since many vats have narrow “deep wells” and/or slanting bottoms, removal and filtering of the oil becomes a major problem. After immersion, the unit must be manually transferred to and from fouled and unfouled oil in each vat and catchment container, potentially a very messy, spill-prone process. 
     U.S. Pat. No. 4,646,793 is directed to a system for supplying and disposing of oil. The system does not perform flushing or use a pressure dispensing wand for cleaning. The filtering and recirculation capability stores the oil overhead indoors and requires several pumps. 
     U.S. Pat. No. 5,249,511 is directed to a system with supply, disposal, and filtering capability but does not provide a sanitary draining system to flush away larger pieces of food or clumps of heavy bottom sediment. The system relies on a vacuum to extract chunks of debris from under the vat heating tubes and transfers the debris, unstrained and unfiltered, through an extensive piping and valve network to a large remote processing unit. Cross-contamination remains a possibility from a piping network flooded with fouled oil and food bits. Furthermore, the oil storage unit indoors is a fire hazard. 
     U.S. Pat. No. 3,369,602 is directed to a edible oil handling system which requires multiple pumps and separating devices and the pump motor to be continuously running. There is no provision for disposing of the spent oil. 
     U.S. Pat. Nos. 3,707,907, 4,945,893 and 5,179,891 are directed to edible oil handling systems requiring proprietary “built-in” mating components in order to function properly with the vat system. 
     While each of these efforts addresses various segments of edible oil handling, filtering and disposal, none present a safe and effective comprehensive system for distributing, storing, filtering, disposing and recycling of edible oils or other fluids, while in a hot condition. 
     SUMMARY OF THE PRESENT INVENTION 
     The preferred embodiment of the apparatus of the present invention solves the aforementioned problems in a straight forward and simple manner. What is provided is a process of and system for distributing, filtering, storing, recovering, and disposing of bulk edible oil or other fluids, often while in a hot condition, for use in open-top vat type vessels such as fryers, cookers, and related equipment widely used in commercial or institutional food preparation establishments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawing, and in particular FIG. 7, the system of the present invention is designated generally by the numeral  200 . System  200  is generally comprised of a interior worksite system  148 , exterior worksite system  149  and mobile distribution and recovery system  150 . 
     FIG. 1 illustrates the filter box assembly  18  of the interior worksite system  148  of the present invention. Filter box assembly  18  is comprised of filter box  8 , sump  5 , lid  15 , filter element  20 , septum  24  and holddowns  25 . In the exemplary embodiment, filter box  8  is made of stainless steel. Filter box  8  is comprised of two handles  9  (only one shown), sides  10 , lip  11  having an upward outward turn, bottom ledge  12 , four casters  13  with wheels, preferably cushion rubber wheels, and four caster mounting pads  14  for affixing the casters  13  to the bottom of filter box  8 . Lid  15  has on its top side  17  a lid handle  19 . Side  16  of lid  15  is so constructed to provide a mating fit with lip  11  thereby securing lid  15  to filter box  8 . Sump  5 , the bottom floor of filter box  8 , allows the use of flat sheet septum stock by dispersal of vacuum under weight comprises a drain strainer  7  having holes and sides  6 . Drain strainer  7  couples to tee fitting  3 . Sides  6  vertically diverge upward to form a tapered fit with matching filter element  20 . Filter element  20  comprises filter element frame  21 , filter grill  23  and vertically diverging upward corners  22 . The vertically diverging upward corners  22  provide a small amount of elevation from the floor of sump  5 , thereby dispersing a partial vacuum drawn through the drain strainer  7  and forming a collecting place for the filtered fluid. Filter grill  23  supports septum  24 . Preferably, septum  24  is made of paper or any suitable porous material having a porosity of a micro-pore level to achieve the desired filtration level. Four filter holddowns  25  (only one shown) are positioned on top of the septum  24  thereby holding the septum  24  down. Filter holddowns  25  comprise bar  27  for providing a weight to hold down the septum  24  and handle  26  for picking up the bar  27  when removing the septum  24 . Filter aides (not shown) of fine powder such as diatomaceous earth are often sprinkled over septum  24  to form a porous, spongelike filter cake for enhancing the filtering process and preventing clogging. 
     Oil or other fluid is suctioned down through the filter aides and septum  24  to drain strainer  7  and into tee fitting  3  by pump  38  (FIG.  2 ). The filter aides and septum filters the oil or fluid thereby separating the particulate matter from the oil or fluid. One end of tee fitting  3  is connected to a cleanout plug  4 . The other end of tee fitting  3  is connected to one end of drain pipe  2 . Drain pipe  2  is preferably connected to a female quick disconnect fitting  1  for connection to fluid intake line  49  (FIG.  2 ). 
     Filter box assembly  8  is of a simple construction for ease of use and cleaning. The filter box assembly  8  can be picked up by one man via handles  9  and drain pipe  2  can be easily rodded out by removing cleanout plug  4 . However, simple hose flushing with hot water will suffice when cleaning drain pipe  2 . 
     FIG. 2 illustrates the filtering system  51  of the interior worksite system  148  of present invention  200 . Filtering system  51  comprises filter box assembly  18  (FIG.  1 ), supporting superstructure  28  and fluid transfer unit  50 . Filter box assembly  18  is used as a vehicle or portable caddy to transport the fluid transfer unit  50  and supporting superstructure  28 . Supporting superstructure  28  comprises four standoff structures  29  (only two shown) secured to filter box  8  and extended outward therefrom to distance two channel rails  30  far enough from the filter box such that lid  15  has sufficient side-to-side clearance for access. Further provided are movable sockets  31  mated with channel rails  30  thereby facilitating a sliding movement of sockets  31  to various locations along channel rails  30 . Removable support frame  32  has four legs  33  which sit in and may be secured to movable sockets  31 . Motor pump mounting base  34  is secured to removable support frame  32  and supports pump motor  35  and switch junction box  37 . 
     The fluid transfer unit  50  comprises pump  38  coupled to switch junction box  37  and receives electrical power via power plug and cord  36 . Power plug and cord  36  connects to a conventional 110 V.A.C. wall outlet. Pump  38  is provided with a pressure relief valve. Pump  38  has fluid intake manifold  39  on its inlet side and a fluid discharge manifold  40  on its outlet side. The fluid intake manifold  39  and fluid discharge manifold  40  couples to its own three-way valve  41 . Each three-way valve  41  selectively directs fluid through elbows  43  via three-way valve switch handles  42 . 
     On the inlet side of the fluid transfer unit  50 , filtered fluid intake line  49  couples to three-way valve  41  via elbow  43  on one side of three-way valve  41 . The other side of three-way valve  41  is coupled fresh fluid line male quick disconnect fitting  48  via another elbow  43 . During the normal filtering mode, filtered oil or fluid is suctioned from drain pipe  2  through filtered fluid intake line  49  and aforementioned connections and discharged out through vat/wand dispensing line  47  and into a vat or catchment vessel. The normal filtering mode is performed by manipulating the two three-way valve switch handles  42  having corresponding positions  166  (FIG.  8 B). For a fresh (new) fluid intake mode, the two three-way valve switch handles  42  are manipulated in accordance with positions  167  (FIG. 8B) whereby fresh oil or fluid is coupled to fresh fluid line male quick disconnect fitting  48  when fresh fluid supply line  86  (FIG. 5) is connected thereto for supplying fresh fluid from supply and disposal storage tank  115  (FIG. 6) to the vat/wand dispensing line  47 . 
     On the outlet side, vat/wand dispensing line  47  connects to a swivel nut female connector  45 . Swivel nut female connector  45  connects to elbow  43  via adaptor fitting  44 . Adaptor fitting  44  connects to elbow  43  which connects to one side of three-way valve  41 . The other side of three-way valve  41  connects to elbow  43  which connects to disposal line female quick disconnect fitting  46 . During a waste (old) fluid disposal mode, the two three-way valve switch handles  42  are manipulated to positions  168  whereby waste oil or fluid passes through disposal line female quick disconnect fitting  46  when spent (old) fluid disposal line  87  (FIG. 5) is connected thereto for directing waste (old) fluid out into the supply and disposal storage tank  115  (FIG.  6 ). In the exemplary embodiment, vat/wand dispensing line  47  is a high temperature food grade pressure rated flexible hose. 
     FIG. 3 illustrates a profile view of filtering system  51  with pump motor housing  56  and dispensing wand system  66 . Filtering system  51  is further comprised of an access opening  54  for supporting quick disconnect male adaptor  55  thereby accessing the interior of filter box  8 . Access opening  54  is custom fitted on site. Further provided are quick disconnect male fitting  52  coupled to filtered fluid intake line  49  via swivel fitting  53 . Quick disconnect male connector  52  couples to the female quick disconnect fitting  1  thereby completing the connection for suctioning the filtered fluid from drain pipe  2  through filtered fluid intake line  49 . Pump motor housing  56  is depicted by the dotted line enclosure around pump motor  35 , pump  38  and switch junction box  37 . Pump motor housing  56  protects the enclosed equipment and is further equipped with toe rail  57 . 
     Oil or fluid exits the filtering system  51  via dispensing wand system  66 . Oil or fluid flows through vat/wand dispensing line  47  into wand swivel male fitting  58  connected to an optional ball valve wand shutoff  59 . Fluid or oil then enters wand nozzle  60 . Rear handle shank  61  serves as a mounting post for rear insulated wand handle  63 . Front handle shank  62  serves as a mounting post for a top insulated wand handle  64 . An optional trigger  65  may be required for an electrically controlled module using electrical solenoid valves (not shown) in place of the two three-way valves  41  and manual three-way valve switch handles  42 . An electrical wire line (not shown) for optional trigger  65  originates at the switch junction box  37 . The electrical wire line is paired and routed with vat/wand dispensing line  47  to control the power to the pump motor when the optional trigger  65  is actuated. An electric solenoid valve  202  is provided on each of the discharge and intake lines (thus, there are four such valves  202  in the preferred embodiment). Lead wires  203  (two per side for a total of four (4)) connect valves  203  with toggle switches  158 ,  159 ,  161  and  162 , best seen in FIG. 8-A. Control panel  153  is mounted on the front face of housing  56 . 
     FIGS.  4  and  4 -A illustrate a position location which may be used in a portable “roll around” mode of operation which is desirable when there is no space available for a filter box at the end of a line of fryers, or if cooking vats supported by cabinet legs  74  are placed in several locations instead of being cascaded. 
     The filtering system is provided with a utility shelf area  78 . The toe rail  57  (FIG. 3) is provided with toe rail stanchions with threaded ends  79 . The pump motor housing  56  (FIG. 3) has a flange  80  and provides an open end  81  for access to the two three-way valve switch handles  42 . The pump motor housing  56  is further provided with hinge  77  and latch  76 . 
     Quick disconnect male fitting  55  passes through the filter box  8  (FIG. 3) at access opening  54 , a hole pierced through filter box  9  on site to match exactly the altitude and location of the low terminal end of the common manifold line. Quick disconnect male fitting  55  connects to quick female disconnect fitting  67  which connects to vat jumper line  69 . Vat jumper line  69  is secured via worm drive band clamps  96 . Vat drain ball valve  70  is coupled to vat jumper line via connection or drain spout  71  of vat  73 . Workstation  75  is provided with a cabinet housing  73 . 
     This arrangement illustrates a vat jumper hose manifold passing through an open cabinet access. 
     FIG. 5 illustrates the interior worksite system of the present invention. The interior worksite system of the present invention comprises filtering system  51  for connection to a docketing station  90  and to a plurality of cascaded catchment vessels. 
     Docketing station  90  comprises fresh (new) fluid supply line  86  and spent (old) fluid disposal line  87 . Fresh (new) fluid supply line  86  is provided with female quick disconnect single shutoff connector  88  for connection to fresh fluid line male quick disconnect fitting  48  (FIG. 2) when the system operates to intake fresh fluid from the supply and disposal tank  115  (FIG.  5 ). Retaining clips  91  and line support means  92  support fresh (new) fluid supply line  86  and spent (old) fluid disposal line on the wall of the worksite, until needed. Spend (old) fluid disposal line  87  is provided with male quick disconnect fitting  89  for coupling the spent (old) fluid disposal line  87  to the disposal line female quick disconnect fitting  46  (FIG. 2) when the fluid in the system is discarded and stored in supply and disposal storage tank for later transport away from the worksite. 
     Filtering system  51  connects to workstation  75  via a common manifold line connecting a plurality of cascaded vats or catchment vessels. Quick disconnect male adaptor  55  (FIG. 3) connects filter box  8  (FIG. 3) to collector manifold  82 . Vat drain ball valve  70  couples to a drain spout  71  of the catchment vessel which connects to tee fitting  84 . Tee fitting  84  couples on one branch to toe nipple  95  and on the other branch to terminating clean-out plug  85 . Toe nipple  95  then connects to an input side of flexible sleeve  83 . The output side of flexible sleeve  83  is coupled to another toe nipple  95 . The series connection of tee fitting  84 , connected to toe nipple  95  and to flexible sleeve  83  and to another toe nipple  9 S is repeated for each and every catehment vessel of the cascade. The output side of the last catchment vessel connects to collector manifold  82  whereby fouled fluid flows through the common manifold and into the filtering system  51 . 
     With a number of cascaded catchment vessels or vats together on a common manifold, fouled fluid flows from the drain spout  71  when vat drain ball valve  70 , is opened. FIG. 5-A illustrates an alternative embodiment of the common manifold line. The fouled fluid flows from vat drain ball valve  70  into connector nipple  93  which couples to tee fitting  94 . Tee fitting  94  couples to toe nipple  93 . Flexible sleeve  83  is secured by worm drive band clamps  96 . The final tee fitting  84  couples to toe nipple  93  and to quick disconnect fitting  97 . 
     FIG. 5-B illustrates another alternate embodiment for the common manifold line. Manifold pipe  99  does not incorporate flexible sleeve  83 . Vat jumper hose  69  is held in place at its ends by worm drive band clamps  96 . The starting high end of the manifold line uses pivot point pipe nipple  98  for controlling the pitch downward of the manifold line. At the low end of the manifold line, quick disconnect fitting  97  couples to the filter box  8  (FIG.  3 ). The flexible sleeves held by worm drive band clamps  96  permit rapid field installation on relatively level surfaces with vat drains of similar heights. The manifold line must be preassembled before installation and once connected at the pivot point it is pitched downward to a vertically adjusted support bracket (low side)  100  mounted to the vat cabinet at attachment points  101  with bolts or self-tapping screws. The collector manifold pipe  99  is mounted firmly to support bracket  100  with a “U” bolt  102 . The lower ends of all manifold types terminate with a quick coupler socket fitting  97 . Optionally a short length of high temperature food grade flexible hose secured with said worm drive band clamps  96  can be used for added flexibility between quick disconnect fitting  97  and the manifold line. The quick disconnect fitting  97  connects to a quick disconnect male adaptor fitting  55  which passes through filter box  8  (FIG. 3) at access opening  54 , a hole pierced through filter box  8  on site to match exactly the altitude and location of the low terminal end of the common manifold line. 
     FIG. 6 illustrates mobile distribution and recovery system  150  and exterior worksite system  149  of the present invention  200 . In the recycling process, the mobile transport truck  125  links the production source (a refinery) to the end user (fast food restaurants, etc.) and thence back to a final destination (the same refinery or recycling plant). 
     The mobile transport truck  125  comprises multiple separate fresh (new) fluid compartments  126  and a large waste fluid compartment  127 . All compartments are provided with heat strips  128  coupled to electrical resistant units in contact with or adjacent to the tank near the bottom, as best seen in FIG.  6 . The electrical resistant units are equipped for battery or generator operation when the mobile transport truck is mobile, and conventional wall outlet power when parked at the distribution point. On delivery, fresh oil normally flows out by force of gravity. Additionally, a fresh fluid pump  130  is provided to pump the fresh (new) fluid out. The fresh fluid passes through a ticket printing flowmeter  131  to a hose reel  132  and through a truck supply hose  119 . A supply shutoff valve  133  coupled to truck supply hose  119  controls the flow of fluid to truck dispensing nozzle  134 . 
     In the exemplary embodiment, supply and disposal storage tank  115 , made of stainless steal, is shaped cylindrically and positioned horizontally. Supply and disposal storage tank  115  comprises an interior tank partition  118  dividing a larger fresh (new) fluid compartment  116  from a smaller waste fluid compartment  117 . The fresh (new) fluid is introduced into the fresh (new) fluid compartment  116  via the tank locking vent/fill fitting  113  when truck dispensing nozzle  134  is coupled thereto. In proximity is a fresh fluid vent  111  with provision for a dipstick. Fresh (new) fluid exits the fresh (new) fluid compartment  116  through a fresh fluid tank shutoff gate valve  109  and into fresh (new) fluid supply line  86 . Adjacent to it is a capacity gauge  110  for indicating the fresh (new) fluid level. The capacity gauge  110  should be monitored to prevent an overflow of the fluid when flowing into the fresh (new) fluid compartment  116 . Additionally, personnel should monitor the capacity gauge  110  to determine when the fresh (new) fluid supply is low and an order for fresh (new) fluid is required. Heat pipe  107  extends from outside of one tank end through both compartments  116  and  117  and projects outside the other tank end. The waste side of said heat pipe  107  is fitted with a heat pipe elbow  104  connected to expansion riser  105  and riser cap  106  connected thereto. They provide expansion room for a heat transfer fluid that distributes fluid the length of heat pipe  107 , thereby transferring heat through the heat pipe wall to the supply and disposal storage tank contents, in both compartments  116  and  117 , using a thermostatically controlled heat source  108 , to provide viscosity maintenance when outside temperatures are below the solidification point of the edible oil or other fluid. Heating the fresh (new) fluid and the waste (old) fluid induces a slow circulation of the fluids, thereby preventing stale pockets of non-movement which can give rise to undesirable bacterial growth in some fluids. Fresh fluid flows into the worksite building via fresh fluid supply line  86  (FIG.  7 ). Waste (old) fluid flows out through spent fluid disposal line  87  and into the supply and disposal storage tank  115 . 
     Waste (old) fluid ready for disposal enters supply and disposal storage tank  115  via waste fill fitting  114  adjacent to a waste vent/dipstick fitting  112  serving to relieve air and monitor the contents as compartment  117  when filled. Disposal discharge ball valve  103  serves as an exit. Disposal discharge ball valve  103  is fitted with a disposal quick disconnect male fitting  136  for coupling truck collection hose  120  via quick disconnect fitting  121 . The waste fluid is retrieved from the waste fluid compartment  117  and communicated to the mobile transport truck  125  for disposing of the waste fluid. 
     Vacuum modulator  135  comprises air cleaner/muffler  124  and vacuum modulator valve  123 . Vacuum modulator  135  is attached to truck collection hose pipe handle  122 . The vacuum modulator  135  when coupled to quick disconnect fitting  121  introduces air to regulate suction of the waste fluid from waste fluid compartment  117  thereby preventing supply and disposal storage tank  115  from collapsing and providing for stronger suction force (when closed) for heavier fluids. waste fluids can be pumped, but vacuum withdrawal via pump  129  located on the mobile transport truck  125  is preferred. 
     FIG. 6-A illustrates a frontal view of a insulated tank enclosure  201 . A hinged top cover  137  provides access to inspect the supply and disposal tank  115  and/or to fill the supply and disposal tank  115 . Enclosure  201  has a protruded shape to off-shoot snow or other precipitation and provide space for logos or the sort. A top cover lock  139  prevents unauthorized access into enclosure  201 . A top cover hinge  140  allows top cover  137  to rotate in an upward rearward motion. Corner boards  141  join siding panels  142  to form a rectangular enclosure. Foam insulation board  143  insulates the enclosure to retain heat. Supply side fittings  144  and opposite waste side fittings are both provided a housing access door  147  for inspection and service. The supply and disposal storage tank  115  sits on a vertically deposed tank cradle  145  at each end, preferably of flat cast concrete with an insulated cradle liner of rubber composition or the like. Between both cradle ends is positioned a cradle spine  146  made of an appropriate length of pipe approximately 4″ in diameter with a threaded rod passing from end to end of the supply and disposal storage tank  115 . Further provided are associated washers and nuts on each end (not shown). When tightened, the nuts compress the cradle ends against the pipe thereby forming a rigid compression structure which is difficult to capsize. 
     FIG. 7 illustrates a profile and perspective view of system  200  of the present invention. The interior worksite system  148  is shown inside the building. The worksite wall  151  is pierced to form a hole thereby allowing fresh (new) fluid supply line  86  and the spent fluid disposal line  87  to access the exterior worksite storage system  149  thereby connecting the two systems together. Mobile distribution and recovery system  150  operates to deliver the edible oil or other fluids and collect the waste (old) oil or other fluid for future recycling. In the exemplary embodiment, the worksite interior system  148  in stationed in the kitchen for a food service establishment.
