Influence of three factors microwave drying of wood
Wood microwave drying equipment in the drying process by the timber itself is also a great influence factors , these factors are mainly in the following three aspects:
1 , species : For rigid hardwood and hard dry wood , can be used all the various drying methods . Long with a good control system , the control quality is better, and it was confirmed less. In general cases, the preferred selection of steam or hot water, dried and dried by heating in order to ensure the quality and reduce the investment and cost ; dried hardwood thick hard or squares , the drying method with the general difficult to ensure the quality , and the cycle is very long, with most suitable wood microwave vacuum dryer .
2, Specification: Thickness main factors . Timber having a large thickness is difficult to dry. Fast drying , the drying quality does not meet the requirements. Ensure the quality of drying and drying speed. Wood microwave drying machine is suitable for breathable hardwood timber wood slab or easily wrinkled . As for the drop in conventional drying , etc., scrap large hard dry wood , may also consider the microwave or high frequency drying .
3 , Moisture: dry and low-temperature drying high initial moisture content of wood , the best economic results . Dehumidification drying especially in the case of high moisture content , the wood microwave drying equipment thermal efficiency . If other drying methods , heat efficiency is low. Especially in the beginning stages of drying , need to exclude a large amount of water , it may consume a large amount of heat.
