Abstract
A food waste mixing and heat treating vehicle used in feeding hogs has a wheeled chassis. A mixing drum is rotatably mounted on the chassis having an inner wall forming a mixing and heating cavity and having an opening into the cavity. Means are provided for rotating the mixing drum. Two opposing helical mixing blades are each affixed along the inner wall from the opening into the cavity for drawing the food waste into the cavity from the opening, mixing the food waste in the cavity and evacuating the food waste out of the cavity through the opening. Steam injecting means are along the inner wall within the cavity for injecting steam through the food waste for heat treating the food waste for later feeding hogs after the food waste has cooled. The method involves the collecting, heat treating and feeding of the food waste to hogs with the vehicle. The hog lot for raising and feeding hogs the heat treated food waste comprises a plurality of adjacent elongate pens with a juxtaposed feed pen there along. The feed pen is easily accessible by the vehicle.
