Abstract

A system for pumping cooking oil from a filtration device or cooking oil reservoir to a storage tank or back into the cooking oil reservoir. The system can also be used to pump oil from the storage tank to a disposal location. The system can include a pump used to pump oil from one location to another. The system can include a housing for containing the pump and/or the storage tank. The system can include a fresh oil storage tank.

Claims

1. A cooking oil storage and filtration system for use in a kitchen with a cooking oil reservoir and a filtering pan, the filtration system comprising:

a used oil storage tank for storing used oil;

a new oil storage tank for storing new oil;

an oil dispensing and removing system for dispensing oil to and removing oil from an external location;

a filtration system for filtering used oil;

a pump and valve system that removes oil via an oil inlet/outlet system from an external source and provides the oil to the filtration system, wherein the pump and valve system further either provides the oil to the used oil storage tank or returns the oil via the oil inlet/outlet system to the external source;

a first plurality of sensors installed on the new oil storage tank, the first plurality of sensors determining a first level and a first temperature of oil in the new oil storage tank;

a second plurality of sensors installed on the used oil storage tank, the second plurality of sensors determining a second level and a second temperature of oil in the used oil storage tank; and

a control system with a user interface that permits an operator to control the operation of the system, the control system configured to monitor a first volume in the new oil storage tank via the first plurality of sensors and configured to monitor a second volume in the used oil storage tank via the second plurality of sensors, the control system configured to determine a filtration frequency based on at least one of;

the first volume, the first temperature, the second volume, or the second temperature, the filtration frequency associated with volume of oil pumped through the filtration system,

wherein;

the control system includes a communications component that signals to a remote location the first volume and the second volume to signal to the remote location when to replenish the new oil storage tank and when to collect the used oil;

the control system monitors and calculates the volume of oil dispensed from the used oil storage tank and the new oil storage tank per unit of time based at least on the first volume and the second volume;

the control system provides alerts when the first volume is below a first predetermined value or the second volume exceeds a second predetermined value;

the control system actuates the pump and valve system to filter the used oil when the filtration frequency is below a predetermined threshold frequency; and

the control system actuates the pump and valve system to filter the used oil when the first temperature and the second temperature are out of range.

2. The system of claim 1, wherein the used oil storage tank, the filtration system, and the pump and valve system are mounted within a housing.

3. The system of claim 2, wherein the used oil storage tank, the new oil storage tank, and the pump and valve system are mounted within an interior storage volume of the housing.

4. The system of claim 3, wherein the filtration system further comprises a filtration pan, and wherein the filtration pan is mounted within the interior storage volume of the housing.

5. The system of claim 1, wherein the oil dispensing and removal system comprises a wand that can either suck up oil or deposit oil into the external location using the pump and valve system.

6. The system of claim 1, wherein the user interface is a touch screen.

7. The system of claim 1, wherein the oil is transferred from the new oil storage tank to the old oil storage tank via the pump and valve system.

8. A cooking oil storage system comprising:

a filtration system that filters cooking oil;

a used oil storage tank;

a new oil storage tank;

an oil dispensing and removing system that dispenses oil to and removes oil from an external source;

a pump and valve system that is coupled with the used oil tank, the new oil tank, and the oil dispensing and removing system to permit oil to be dispensed and removed, filtered and stored;

a first plurality of sensors that determine a first level and a first temperature of oil in the new oil storage tank;

a second plurality of sensors that determine a second level and a second temperature of oil in the used oil storage tank;

a control system that has a user interface that permits control of the pump and valve system, the control system configured to monitor a first volume in the new oil storage tank via the first plurality of sensors and configured to monitor a second volume in the used oil storage tank via the second plurality of sensors; and

a housing that houses the used oil storage tank, the new oil storage tank, the oil dispensing and removing system, the filtration system, the pump and valve system, and the control system,

wherein;

the control system determines a filtration frequency based at least on the first volume, the second volume, the first temperature, and the second temperature, the filtration frequency associated with volume of oil pumped through the filtration system;

the control system includes a communications component that signals a remote location the first volume and the second volume to signal to the remote location when to replenish the new oil tank and when to collect the used oil;

the control system monitors and calculates the volume of oil dispensed from the used oil storage tank and the new oil storage tank per unit of time based at least on the first volume and the second volume;

the control system provides alerts that the oil should be added when the first volume is below a first predetermined volume or that the oil should be removed when the second volume exceeds a second predetermined volume;

the control system actuates the pump and valve system to filer the used oil when the filtering frequency is below a predetermined threshold frequency; and

the control system actuates the pump and valve system to filer the used oil when the first temperature and the second temperature are out of range.

9. The system of claim 8, wherein the used oil storage tank, the filtration system, and the pump and valve system are mounted within the housing.

10. The system of claim 9, wherein the used oil storage tank, the new oil storage tank, and the pump and valve system are mounted within an interior storage volume of the housing.

11. The system of claim 10, wherein the filtration system further comprises a filtration pan, and wherein the filtration pan is mounted within the interior storage volume of the housing.

12. The system of claim 8, wherein the oil dispensing and removal system comprises a wand that can either suck up oil or deposit oil into the external location using the pump and valve system.

13. The system of claim 8, wherein the user interface is a touch screen.

14. The system of claim 8, wherein the oil is transferred from the new oil storage tank to the old oil storage tank via the pump and valve system.
