wood drying equipment technology
What is the reliability of wood drying equipment?
The more complex the wood drying equipment is, the more complex the technology is, and the more prone to failure. The reliability of the equipment mainly depends on the manufacturer's technology, equipment configuration and after-sales technical service, and the primary concern is the performance and quality of the equipment.
Generally speaking, the material of circulating fan in drying room should be made of aluminum alloy, and its blade should be symmetrical twisted wing type, with high strength, corrosion resistance and rate. The matched direct connected motor shall be class H insulated high temperature and moisture-proof motor. The air flow velocity of the circulating fan should be 1.5 ~ 2.0m/s. If the air velocity is too low, the uniformity and drying speed of wood drying will be affected; if the air velocity is too high, the power consumption and drying cost will be increased unnecessarily.
Generally, the heater in drying room should adopt steel aluminum composite finned tube, and the heat dissipation area should reach 2 ~ 5m2 / m3 dried wood. It should be noted that when drying oak and other tree species, the wood will release corrosive acid substances. Therefore, special attention should be paid to the maintenance of drying equipment. No matter which kind of drying equipment is used, its service life is related to the maintenance level.
The loading capacity of wood drying equipment is also a problem that can not be ignored. The clearance size of the drying chamber shall be the actual volume capacity specified. The ratio of the volume of wood loaded into the drying chamber and the volume of the drying chamber is called the loading factor or loading factor. It depends on the stacking factor of the pile. The stacking coefficient is the ratio of the actual volume of wood to the volume of the stack.
Process display of wood drying equipment:
Wood drying equipment technology laminated wood, to ensure the uniformity of materials;
Preheating wood; wood drying; moisture and heat treatment; air conditioning; cooling. Violation of any stage of the demand process, or even the loss of a whole batch of materials. Due to the use of wood drying equipment, the potential loss of inferior kiln quality is due to non drying process conditions. There is also a more important factor - wood drying equipment process of drying equipment. In general, more than 10% of the waste after use is produced. Qualitative drying equipment quality of wood drying, even if all the technical requirements of wood drying equipment is impossible without good drying equipment. We offer two types of wood drying kilns: convection wood drying equipment. Drying is due to direct exposure to hot air, blowing wood out of all moisture. Hot working - drying and steaming of wood by heating
