Characteristics of vacuum wood drying kiln
Compared with the conventional drying, vacuum wood drying kiln can be achieved under the condition of low temperature rapid drying of wood, and ensure the quality of wood drying, largely avoid the generation of wood shrinkage defects.Through expert analysis to explore the discovery, cypress, for example, above the fiber saturation point, vacuum drying rate for conventional dry 2.34 ~ 2.88 times;While in the FSP, is 2.90 ~ 4.14 times.

Precautions during the operation of steam drying kilns
Precautions during the operation of steam drying kiln: The steam pressure supplied to the drying kiln is generally controlled within 0.3~0.5MPa, and it is best to stabilize at around 0.4MPa. If the steam pressure is unstable, it will affect the stability of the temperature and humidity of the medium in the drying room, making it difficult to control the temperature and humidity of the drying medium.

Comparison of air drying, conventional kiln and solar drying
Broadly, there are two methods by which wood can be dried: natural drying or air drying, and artificial drying. Wood drying kiln provides a means of overcoming the limitations imposed by erratic weather conditions. In kiln drying as in air drying, unsaturated air is used as the drying medium. Almost all commercial woods of the world are dried in industrial kilns. A comparison of air drying, conventional kiln and solar drying is given below:

Drying process of wood heat pump dryer
Drying process of wood heat pump dryer: 1. Install the wood according to the decoration standards, close the drying room, and turn on the control system. 2. Preheating: Turn on the heat pump and fan, set the upper temperature limit to 45 ℃. In order to save preheating and heating time, turn on the electric auxiliary system, and control the ambient temperature from 20 ℃ to 45 ℃ for heating and insulation time within 14 hours; At this stage, the energy efficiency ratio of the heat pump is around 3.5, operating at full load and the fan at full load.

The importance of wood drying equipment service
Wood in certain circumstances, after a long enough time, its moisture content will tend to be a balance value, in order to ensure that the equilibrium moisture content of the environment, so the use of wood drying equipment, is indispensable. Once the lumber moisture content is higher than the environment balance moisture content, the wood will appear the platoon is wet contraction, on the other hand, hygroscopic and expansion of will. So, wood drying, not as dry as possible.

Wood drying equipment of energy conservation and consumption reduction method
Below for everyone to introduce wood drying equipment of energy conservation and consumption reduction method: 1. The application of inverter in the wood drying equipment, greatly save energy in drying equipment, using fan iscompared commonly big, and the fan are almost continuous operation, after using the inverter can save 30% energysaving. After the use of frequency converter, on the other hand, the overall equipment will drop a lot of noise, and prolongs the service life of wood drying equipment.

Convective drying process of wood in a gaseous medium - evaporation of moisture from the wood surface
Evaporation of moisture from the wood surface always takes place at a certain temperature, humidity and air velocity. Under normal circumstances, the humidity of the air in the drying kiln is always less than 100%, while the temperature of the air is much higher than normal temperature. Therefore, the equilibrium moisture content of the air is lower than that of the wood surface, and the moisture on the wood surface evaporates into the air. How quickly water evaporates from the wood surface depends on the temperature and humidity of the air. When the air temperature rises or the humidity decreases, the evaporation rate of water on the wood surface is accelerated; on the contrary, the lower the air temperature, the greater the humidity, and the slower the evaporation rate of surface water.
