The purpose of animal feed drying is to remove the excess water from the feed stock for easy to pack, transport, store, process and use. In view of the animal feed is high humid and viscous, we designed Rotary Harrow Rolling Triple Stage & Multiple-loop Drying Equipment. It uses unique design concept and truly energy saving technology. With the 1 + 3 = 6 three cylinders technology, 3 * 6 = 36 S Type material moving processes, 6 - 3 = 1 fast air exhausting way and Moving forward 3 steps and backward 2 Reciprocating drying method, the dryer operating like a Smart Robot. In the operation of moving forward, backward, directing, conversing, raising, turning, the material contacts with the hot air efficiently, thereby being dried quickly and evenly. Dry material will be discharged into star type unloader, then unload on conveyor for next operation (mixing, cooling and package). The whole process is automatically and controlled by PLC. Equipment operation only need 1-2 people per shift. This drying equipment can also be used for drying forage, distillers grain, cassave residues/pulp, corn pulp, potato dregs, soy sauce residue, soybean wastes, fruit pomace, zymophyte dregs etc. The finished production is very good raw material of organic feed for animals.
