ABSTRACT:
A method and apparatus for dehydrating waste food material. The food material is initially ground to a relatively small particle size and transferred to a porous container or basket in a cooking vessel. The vessel contains a quantity of oil, preferably waste cooking oil, and the oil is maintained at a level beneath the basket. The oil is heated and the heated oil is circulated from the lower end of the vessel and returned to the upper end of the vessel where it flows downwardly through the food material to vaporize the moisture and kill the bacteria in the food material. The circulation of the hot oil is continued for a period sufficient to fully dehydrate the food material and produce a dried product that can be used as an animal feed adjunct.
