Selection of drying equipment

Selection of drying equipment

In addition to analyzing the above factors, the selection of wood drying methods and kiln types should also consider the characteristics of the user, namely output factors, dried wood factors, energy conditions, equipment reliability and site conditions, etc. In short, the final selection of wood drying method is the result of analyzing and weighing various factors.

Drying equipment Solar drying method

It is also an energy-efficient method of drying wood. It uses solar collectors to convert solar energy into heat to heat wood. The main feature of this drying method is that it saves energy, but the drying cycle is long and affected by conditions such as region, season and climate. Therefore, the use of this drying method has certain limitations.

Advantages of drying equipment Dehumidification drying method

The advantage of the dehumidification drying method is that the latent heat of vaporization released by the condensation of humid air can be recovered, that is, the method has almost no or only a small amount of exhaust heat loss; and the process is simple, easy to operate, dry, and generally does not cause wood damage. The disadvantage is that the drying temperature is low and the drying cycle is long. For thick boards or difficult-to-dry materials, it is not easy to dry thoroughly, and the drying cost is high. The vacuum drying method places the wood in a closed drying container, on the one hand, the temperature of the wood is increased, and on the other hand, the pressure in the container is reduced, so that the moisture in the wood begins to vaporize and evaporate at a relatively low temperature, so as to achieve the drying effect of the wood. Purpose. The drying method is characterized by short drying cycle and good drying quality, but high energy consumption, small volume of the container, and complicated control of drying equipment and drying process. It is suitable for hard hardwood planks or shriveled woods with good air permeability. Microwave and high-frequency drying methods have a series of advantages such as simultaneous heating inside and outside, uniform heating, fast drying speed, short cycle, good drying quality, can maintain the natural color of wood, and are conducive to continuous automatic production. The disadvantage is that electricity is used as the energy source, the cost is high, and the equipment performance is not perfect. Preliminary practice has proved that it is suitable for precious tree species (redwood, etc.), wood and hard-to-dry wood.
