A cooking oil salvage and disposal system, including means for receiving and transferring hot, used cooking oil from a food processing building through a vertical exterior wall of said building to a receiving tank mounted externally of said building which comprises:
- A. a conduit extending horizontally through said exterior vertical wall and opening on the inner surface of said exterior vertical wall on the inside of said building;
- B. a receiving tank on the exterior of said building, in communication with said conduit, for receiving hot, used cooking oil from said building;
- C. an insulated tank storage compartment adjacent said exterior wall which contains said receiving tank;
- D. a means for heating the contents of the tank to bring the contents of said tank to the proper viscosity for pumping;
- E. an oil discharge tube for connection to a pump for removing the oil from the tank;
- F. a normally-latched service door on said compartment, to provide access to said oil discharge tube;
- and
- G. latch means operative from the interior of said building for opening said service door.
The process for the safe and sanitary transfer of spent, hot cooking oil, used in a commercial cooker of a food processing building to a storage tank located outside said building, inside a locked, insulated housing and connected to a conduit extending through the exterior wall of said building and opening inside on the inner surface of said wall inside said building, which comprises the steps of:
- A. removing the spent, hot cooking oil from said cooker;
- B. filtering said oil and removing all filterable particles therefrom;
- C. transferring said filtered oil through said conduit from within said building to the storage tank outside said building;
- D. applying the heat necessary to the contents of said tank to bring the spent oil to a pumpable viscosity;
- E. unlatching a service door of said locked insulated housing by manipulation of a latch means inside of said building;
- F. coupling an oil discharge tube from said tank through an opening opened by said service door to a receiver hose, leading to a pump;
- and
- G. pumping the spent oil from said tank for transport to an oil receiving receptacle.
