1.‌ The working principle of wood sawdust rotary dryer machine‌ is to realize the drying of wood chips through the full contact of high temperature hot air with wood chips and heat transfer. The air temperature entering the wood chip tumble dryer can reach about 450 degrees Celsius, the specific process is as follows:
wood sawdust rotary dryer machine‌: wood sawdust containing moisture are passed through the conveyor into the wood sawdust rotary dryer machine. In the roller, the sawdust begins to evaporate under the action of high temperature hot air.

‌Hot air contact with wood sawdust‌: wood sawdust are boiled and fluidized in wood sawdust rotary dryer machine, and the hot air is in full contact with wood chips until the water in the wood sawdust gradually evaporates. This process is accomplished by the combined action of the composite plate and the rotating cylinder.
‌Drying completed ‌: fully dried sawdust from the discharge port to complete the whole drying process.
2. Characteristics and application scenarios of wood sawdust rotary dryer machine has the following characteristics:
‌wood sawdust rotary dryer machine‌ stable operation : stable operation of the equipment, large output, high work efficiency.
wood sawdust rotary dryer machine‌ Energy saving and environmental protection‌ : in the drying process can reduce energy consumption, in line with the requirements of environmental protection.
‌wood sawdust rotary dryer machine‌ strong adaptability‌ : can be flexibly adjusted according to actual needs, it can run for a short time, but also for a long time continuous operation, up to 24 hours uninterrupted operation.
wood sawdust rotary dryer machine is widely used in the production process of biomass pellet such as wood pellet, which can adapt to different production scales and needs, improve the utilization rate and production efficiency of equipment.
