Product Details

Wood chip dryer is for drying wood, wood chips, wood powder, sawdust, shavings, wood chaff and other biomass fuels. It can dehydrate the high moisture content wood chips quickly. It can meet the production demand of subsequent charcoal making. The dryer is internally set with spiral propulsion. It can increase the contact area of material and drying medium. Avoid the material sticking to the impurity cylinder wall. The whole set of wood chip dryer has good sealing performance, and the drying thermal efficiency is higher than the general drum dryer.

According to the characteristics of wood chip materials. The structure of the dryer is analysed to customize the design on the influence of the output and quality of the wood chips. Adopt advanced technology process, which can improve the filling rate of the material and the residence time of the material impurities in the cylinder body and other issues for upgrading. Adopt new type of lifting device and multi-layer sleeve structure. Make the material without wind tunnel phenomenon. So that the wood chips can be quickly heat exchange, dehydration, drying. In increased coarse and fine particle separation device. So as to greatly improve the efficiency of heat utilisation. At the same time, it also improves the production capacity. The environmental protection of the equipment has also been greatly improved. Make it more environmentally friendly and energy saving.

In addition. The wood chip dryer can make full use of the waste heat, which can reduce the heat loss. Increase the effective heat exchange area. The evaporation intensity per unit volume of the dryer is greatly improved. Thus, the heat energy utilisation rate is improved, the energy consumption is reduced, and the thermal efficiency of the dryer is greatly improved.

Technological Process

The main components of the wood chip dryer are: the main body of the multi-layer sleeve dryer, hot air furnace, fan, inlet and outlet equipment, storage bin, pulse dust collector, cyclone dust collector, induced draft pipe and so on.

In the process of wood chips drying, the wet wood chips are first sent to the raw material bin by forklift truck. The wood chips are evenly sent to the dryer by belt conveyor. The wood chips are evenly dispersed and fully contacted with hot air under the even turning in the drying drum. Thus accelerating the wood chips drying heat conduction, mass transfer, evaporation of moisture. The wood chip dryer adopts sealed structure. It can reduce the heat dissipation. After drying, the wood chips naturally fall into the belt conveyor through the unloading hopper. After the conveyor sends the dried wood chips to the designated place for storage. The dust generated at the top of the unloading hopper is processed by the negative pressure of the pulse dust collector, so as to achieve the purpose of environmental protection.
