DingLi three-layer single-channel pasture rotary drum dryer (Patent No.: ZL200920089749.2), the equipment with large output, high efficiency and energy saving, small footprint, which is particularly suitable for high-moisture materials such as pasture grass drying with clean type hot blast stove. It can rapid drying moisture from 65-75% to 14-18% in one-time. Dry grass completely retained the nutrients of fresh pasture, bright color, smell fragrance, energy saving 30-50% than the ordinary dryer, can maximize energy conservation and drying costs. Suitable for drying elephant grass, alfalfa, wheat straw, barley straw, oat straw, rye straw, rice straw, sorghum stalks, corn stalks, potato vines, and 45-75% moisture of pasture straw. According to each material characteristics, production scale, quality requirements, application requirements, cost control, automatic level, on-site conditions, investment quota to optimized drying process technology and equipment configuration services.
Material Flow: the crushed pasture with about 45%-75% moisture is sent into the drum by conveyor to realize downstream drying. Under the effect of inner shoveling plate, materials are taken and scattered constantly and move in spiral forward method. Through the inner, middle and outer three layers, to realize heat exchange between material and hot air medium.
Compared with single drum dryer, it reduces floor space by 50%, decreases civil engineering investments by 50%.
Dryer internal structure using a variety of high-lift board combination mode, effectively regulate the drying process and heat distribution, high heat utilization, exhaust gas discharge temperature is low.
Rapid drying moisture reducing from 45-55% to 15% in one-time. Pasture temperature is always lower than 50 ℃, dried grass completely retained the nutrients of fresh pasture, bright color, smell fragrance.
Supporting a variety of new energy-saving clean hot air blast stove, fuel can be diesel, gas, coal, wood, wood chips, straw etc. And efficient energy, heating controllable, simple operation, energy consumption decreased by as much as 30%, power consumption reduced by 20%, the operating cost is lower.
