Abstract: A mobile cooking oil caddie which includes in combination features of heating, filtering and transporting oil for disposal into a disposal tank. The caddie is rolled under a hot oil fry cooker and hot fats can be drained into the caddie from the cooker. A filter screen is provided in the caddie for filtering the hot fats. If the grease is to be disposed, the caddie is moved to a facility in which the oil is pumped from the caddie by a motorized pump to a disposal tank. If the grease has been stored for a time and is not in a fluid state, the heater can be activated to heat transfer mixture which in turn heats the grease to a fluid state. The filter can then be cleaned of food particles and the caddie stored until it is desired to drain the fry cooker again for receipt of hot fats from the cooker when desired.
