At present, the common practice of processing soybean hulls in edible oil mills is: crushing and peeling, then pulverizing and directly adding to the soybean meal, and finally packaging and selling. But throughout the process, the bean hulls is not sterilized by sufficient heat. Since the disease-causing species may be carried, the soybean hulls is added to the soybean meal without being ripened to raise the animal, which may cause unpredictable animal diseases and even spread to humans. Therefore, the use of hull sterilizer can kill the disease-causing species in soybean hull and ensure the safety of animal feed.
◎ Indirect/direct heating layer and hot/cold air layer for incorporating inactivation, drying and cooling.
◎ Multi-layer heating, automatically controlled layer height, adjustable residence time for evenly heating.
◎ Heating coil along the cylinder to heat the material as well as prevent condensation of water vapor.
◎ Continuous stirring device to ensure sufficient heat exchange between material and interlayers.
