Product DescriptionHIGH FREQUENCY VACUUM DRYING MACHINEThis product is mainly aimed at drying relatively thick materials and large volume wood, which can effectively accelerate the drying speed of such materials. Compared with ordinary drying products, it is more efficient and has better drying effects.Wood vacuum drying is a method of drying wood by stacking it in a closed container and drying it under conditions below atmospheric pressure. Under vacuum conditions, the boiling point of water decreases and the evaporation rate increases, thereby accelerating the drying rate of wood at lower temperatures. During the drying process of wood, on the one hand, surface moisture evaporates into the surrounding air; On the other hand, the internal moisture continuously moves towards the surface. So to accelerate the drying speed, it is necessary to find ways to accelerate the movement speed of moisture inside the wood. In addition, under vacuum conditions, the boiling point of water decreases, causing the evaporation rate of water inside the wood to accelerate, and the moisture content gradient on the wood surface to increase, preventing severe evaporation of water on the wood surface and cracking of the wood surface. While the moisture on the surface of wood evaporates violently, it also absorbs a large amount of vaporization heat, causing the wood surface to cool. These factors all accelerate the movement of moisture inside the wood towards the surface.SpecificationMain featureEfficient, safe, and durable: heating and vacuum simultaneously, use rail cars and related technologies, process high-strength sealing box cover.Temperature uniformity: low energy consumption, uniform heating, and good quality.Fast drying speed: it can achieve a higher drying rate at a lower temperature, fully utilize heat, and the control system is manually set to fully automatic control.Good drying effect: this dryer belongs to a static vacuum dryer, so the shape of the dried material will not be damaged.Under vacuum conditions, the air inside the drying device is sparse, and the usual heating method cannot be used. To solve the heating problem of wood during vacuum drying, a continuous heating method is adopted for vacuum drying. Vacuum drying can eliminate the surface hardening and cracking phenomenon that is prone to occur under atmospheric pressure drying. The pressure difference between the interior and surface of vacuum-dried wood is large, and under the pressure gradient, water quickly moves to the surface. At the same time, it can improve the drying rate, shorten the drying time, and reduce equipment operating costs. In addition, under low-pressure conditions, the oxygen in the drying medium is scarce, and the material discoloration caused by thermal and oxidation reactions is minimal, which can maintain the natural color of the material. Therefore, vacuum drying equipment is a fast drying method. It is also an environmentally friendly drying equipment.Key Configurations1. Vacuum dryers generally use electric heating methods. If the customer has a steam boiler or a thermal oil boiler, it can also be used as a heating source.2. Net cubic volume of wood: 2 cubic meters -3 cubic meters -5 cubic meters -8 cubic meters -10 cubic meters -20 cubic meters.3. Equipment packing size: A 20 size cabinet can hold 2 cubic meters to 3 cubic meters, to 5 cubic meters of drying machine equipment.
