Abstract
A process for the comminution and dehydration of animal waste and/or parts by feeding the animal waste and/or parts into a cyclonic, dehydrating comminuter facilitates the further processing of the comminuted and dehydrated animal waste discharged from the comminuter. Both the comminuted and dehydrated material and the air flow discharged from the cyclonic comminuter are sterilized to remove pathogens therefrom. The rate at which the animal waste and/or parts material is fed into the cyclonic comminuter. is directly related to the moisture content of the comminuted and dehydrated material discharged from the material discharge opening of the comminuter. Preferably, the moisture content of the discharged material is in the range of 25% to 35% to facilitate the pelletizing of the discharged material after being sterilized. Other precesses, however, can require the drying of the discharged material to about 10%. An air flow control mechanism is provided for the cyclonic comminuter to enhance the ability to control the discharge of air from the comminuter. The control is provided with adjustable vanes actuated from a actuator projecting outwardly from the comminuter to permit an easy adaptation to automated controls to restrict the size of the air discharge opening from the comminuter.
