Three channels drum rotary dryer as know as three cylinder dryer. It is used in food, feed, fertilizer, chemical, pharmaceutical, mining industries. According to the different requirements about the dryer. We have a different heat source. For example, direct heating model hot blast stove, indirect hot blast stove, heat conduction oil, electric heating, steam, etc. This dryer is suitable for drying the material with the moisture of less than 65%.
The rotary dryer is suitable for drying wood chips, sawdust, bamboo chips, wood powder, EFB,RDF,solid waste,wood pieces, wood shavings, rice straw, Household waste,wheat straw, corn straw, sorghum straw, maize silage, and potato vines, beanstalks, and so on. The equipment has the advantages of large output, high efficiency and energy saving, small occupation area, energy-saving, and cost-saving.
Working Principle
The crushed materials of which the moisture is about 35%-65% are sent into the roller by conveyor to realize downstream drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle and outer layer), heat exchange is realized between material and hot air medium.
We also provide complete production lines, including crushing-drying-pellet machine-cooler-screening and packaging, etc.
Advantages of Biomass Dryer
1. The three-layer rotary drum dryer has large output, high efficiency and energy saving, and a small footprint. Compared with ordinary dryers, it can save energy by 30-50%, which can maximize energy saving and drying costs.
2. The heat exchange of the three-layer rotary drum dryer is sufficient: the material and the hot air are reciprocating and crossing to achieve heat exchange in the downstream, countercurrent, and downstream. The heat exchange time is long, and the moisture discharged from the evaporation of the material in the inner drum is directly pumped by the fan. Go, heat energy utilization efficiency is high.
