Unmatched Stability The thermal modification process removes all moisture from the wood cells, making it highly stable and resistant to warping, twisting, and bowing.

A building or metal container specially used for drying wood that can adjust and control temperature, humidity and air flow speed according to process requirements. There are two categories: continuous drying kiln and periodic drying kiln.

The carbonization process of carbonized wood is divided into the following three processes: Step 1: Heat up and dry at high temperature in the cellar Heating up, the kiln temperature rapidly rises to 100 ° C.

Thermal modification is currently the most successful and economically significant wood modification method in terms of industrial promotion and application.

Bamboo chips are one of the raw materials of bamboo products. They are narrow in width and long in length. In order to ensure the long-term durability of bamboo products made of bamboo chips, bamboo chips need to be dried after being cut into corresponding sizes to avoid The moisture inside remains, which makes the bamboo products last longer. But most of the bamboo strip dryers used for bamboo product processing now dry the bamboo strips in the transmission, and the bamboo strips will be deformed after being heated.

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 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.

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: 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.

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.
