This machine is widely used for fish meal, blood meal, soybean meal, brewer's grains, corn germ meal, animal manure and high humidity drying, sterilization of material, has reasonable process, compact structure, convenient installation, simple operation, wide adaptation range, strong generality, is an ideal drying equipment in feed industry. Two, 1, the characteristics of thermal capacity coefficient is big, because the rotating effect of drum rotation and the stirring wing, so that the material can be fully and air contact, make the dry strength increased by 2-3 times than the ordinary roller, the coefficient of heat capacity can reach 2 300-500kcal/m h C. 2, due to the use of high temperature (250 DEG -700 DEG) concurrent flow drying and the use of waste heat recovery, the thermal efficiency is increased by 30%, high thermal efficiency. 3, multi function, crushing, granulating, and drying can be completed in one machine. 4, the use of a machine, change the drying parameters can be adapted to a variety of different material drying.
