In the rotary dryer in the direction of the material and the hot gas flow is different, there are two kinds of co-current and counter-current. Material downstream dryer hot air flow direction is consistent with rotary dryer, dryer why most have adopted Downstream it? Downstream of the main features are: 1, in the dryer hot end, materials and hot gas temperature difference, the heat exchange process is quick rotary dryer Price, easily evaporate large amounts of water for a higher initial moisture materials. 2, viscous material into the dryer rotary dryer offer, due to evaporation of surface moisture easily, reducing bond conducive material movement. When used for drying wet coal, to avoid direct contact with dry coal gas temperature caused by fire. 3, the hot end of the downstream operations of negative pressure, can reduce the amount of air leakage into the drying, help stabilize the dryer heat gas temperature and flow rate. 4, feed and coal supply provided with the hot end of the dryer, plant layout more convenient. 5, dryer outlet temperature downstream operations is low, generally available belt conveyor transport. Taking full account of the material properties, particle size, material requirements and final moisture shop layout and other specific circumstances, most manufacturers have used downstream type rotary dryer! Potato slag (slag cassava, sweet potato residue, potato pulp, etc.) is a starch factory, a byproduct of ethanol plants and other manufacturers of rotary dryer models, including an internal moisture, viscosity, in the traditional drying process is easy to stick wall, agglomeration, congestion, drying equipment can not be normal production, damaged the interests of users. Gongyi City Station Street Yu Xin Machinery Factory production of "potato residue special drying machine" can be all kinds of high moisture content of dried potato residue to 12% less time. Cassava residue dryer equipment is national patent technology, equipment preparation of a special thermostat, lifting, guide materials, broken up and other devices, effectively avoiding the sticky wall, plug and so on. Drying out of the material, good color, good quality, energy saving and environmental protection, new and old customers.
