Wood drying machine

Abstract

The invention discloses a wood drying machine, and relates to the technical field of wood processing. The wood drying machine comprises a compressor, a circulation pipe, heat regenerators, an evaporator, a drying controller, an expansion valve, a condenser, evaporation pipes and a conduction pipe. The evaporator is connected with the condenser through the compressor and the expansion valve. The compressor is connected with the expansion valve through the drying controller. The evaporation pipes are of a multi-layer folding structure and are arranged inside the evaporator and the condenser. By means of a closed dehumidifying drying manner, waste gas and waste heat are not discharged, and noise pollution is avoided. The wood drying machine is a high-environment-friendly product and is not affected by the outside, and pollution of emitted smoke of a fire coal and fuel wood boiler is reduced. The wood drying period is shortened, the wood water content can be controlled, and all parts of wood can be evenly dried. The water content of the wood is accurate, stable and even. The shrinkage rate of the dried wood is greatly reduced, the wood surface quality is high, and the phenomenon of surface hardening is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood dryer. Background technique [0002] Wood drying is an important production process in the wood product production process. The quality of wood drying and the cost of drying directly affect the quality and production cost of the final product. Existing wood dryers, no matter what kind of structure they are, have some problems, some have uneven drying, wood close to the heat source is often overdried, and wood far away from the heat source is not yet dry; Because the wood cannot be stacked, it needs to be placed layer by layer, which is time-consuming and laborious; some have a long drying cycle, which lasts for nearly half a month, and the productivity is low; most of them consume high energy consumption and the production cost remains high; some are expensive , Increase the equipment investment burden of enterprises. The object of the present invention is to pr...
