During the working process of spiral blades and indirect spiral lifting boards, raw materials in rotary dryer are dried. Sleeve structure of wood chip dryer makes the length shortened for times while the thermal efficiently greatly improved. Smaller area for heat dissipation, lower the chance for energy consumption. Therefore, the short length causes the high thermal efficiency.

Wood shavings dryer has two drying ways. One is direct drying and the other is indirect drying. Their functions are both to dry the raw materials with water content that customers are satisfied with. For direct drying, heat conduction and water evaporation work at the same time.

Flowing hot air as heat carrier directly contacts with wet materials and conducts heat to them, then brings away the evaporated water. While, the indirect drying mainly relies on the heating carrier. The heating carrier can dry wet materials. 

If you select the stainless steel to make the diabetic and electric devices, ways to count the areas of heat transfer will be based on the heat conduction and transfer of stainless steel. Compared with the heat-transfer coefficient of steel carbon, it is much higher than that of stainless steel.

When selecting the materials, we should take many factors into account. Meanwhile, when using the wood shavings dryer, you should notice every performance of material and make the reasonable plan. The purpose of above efforts is to make wood pellet mill work more high-efficiently and energy-conserving.
