Offer: microwave vacuum chamber aim-080-waDate: 2017.06.28
Lumber drying chamber for all types of wood, with high performance and without defect conventional convection and vacuum drying. With the drying cycle of 12-24 hours. Preferential use in the forest and wood industry for drying and building rounded logs in the manufacture of log houses. The drying chamber is composed of a frame fixed horizontally on the cylindrical body for waveguides with microwave energy from magnetrons-stage nozzles and to connect the compressor, and to the body at its ends sealingly attached to the rotating drive section located on the support rollers and having to load the outside lid timber. The use of this device will provide increased productivity, quality of timber drying and reduced drying time.

beech boards 50 mm - 30 hours
beech boards 100 mm - 40 hours
Pine, cedar, fir up to 200 mm - 24 hours
birch, linden and 200 mm - 20 hours
Description of work:
One of the promising trends in the intensification of the wood drying is the use of electromagnetic energy of ultrahigh frequency (UHF). The rapid increase in temperature inside the timber, which is characteristic of microwave heating, the water vapor pressure increases, that is, there is excess vapor pressure within timber relative to the pressure medium. This gradient overpressure sharply intensifies the drying process, since in this case the steam is transferred by a molecular diffusion and by filtration through the pores and capillaries of the wood.
Microwave Vacuum drying chamber works offline. For installation required a voltage of 380 V. In order to cool the magnetron used modular units are air-cooled. Heated air from the modular air cooling units is fed into the guide for removing moist air, thereby increasing the efficiency of the entire installation. The guide has a special shape. The heated feed air is not used as a drying agent for transportation and suspended in the steam chamber beyond. The air is heated to th
