What is the principle of wood dryer wood dryer

Wood can be made into furniture, paper, crafts, etc. for a wide range of uses. The trees that have just been cut down need to be dried before they can be used normally. This has the use of wood dryers. What is a wood dryer? Some people are also very curious about the operating principle of this machine, worrying that it will fail, what is the principle of the wood dryer?

1. What is a wood dryer?

The wood dryer is a large piece of equipment, and the smallest one is more than one meter high and three or four meters long. Large ones can reach four or five meters high and more than ten meters long. It appears for the drying of wood chips, wood boards, and veneers. And it has the characteristics of high speed, large drying capacity, water content standard and low drying cost. For the majority of wood processing enterprises.

The wood dryer is specially designed for the drying of sawdust, small wood chips and veneer. It has the characteristics of remarkable energy saving effect, large drying output and low maintenance. The main working principle is: the wood chips enter the wood chip dryer and the spray pipe and the rotary cylinder work together. The material is boiled and fluidized in the cylinder, and the hot air is in full contact with the material to complete the drying. The so-called airflow sawdust dryer refers to the powdered wet sawdust, which is continuously added to the drying pipe by a screw conveyor. In the transportation and dispersion of the high-speed hot gas stream, the water in the wet material is evaporated to obtain a powdery or granular dry product. Mainly composed of air heater, feeder, airflow drying pipe, cyclone separator, fan and so on.

Second, the principle of wood dryer

When the wood dryer is in normal operation, the fuel in the machine will burn in the combustion to produce heat. These heat energy is fully absorbed by the heat transfer medium, and then the medium will evenly absorb the absorbed temperature in the wood raw material box of the dryer to form a high temperature of about 180 degrees, and then the entire heat circulation fan in the equipment will be used. The air in the oven is circulated, and the high temperature and air circulation make the drying effect very good.

The steam generation system on the equipment can generate a large amount of hot steam. We transport these high-temperature steam to the drying box and steam the wood. This has the advantage that the wood will be quickly together from the inside out. Warming up, and some fine-grained wood will not cause cracks, deformation and other problems due to the principle of thermal expansion and contraction, and by heating at high temperature, the aphids and eggs in the wood can all be burned to death, and the safety of wood products will be higher.

The design of wood drying is very rational. It not only takes into account the cost of the equipment, the efficiency of the work, the workload of the work, but also retains some margin and additional components, so that when we dry the wood Even if the amount is a little higher than the budget, there is no problem.

What is a wood dryer? A wood dryer is a machine that can help wet and wet wood to dry quickly and thus make better use. The principle of wood dryer is easy to be as above. Generally, wood dryers can only be used in large factories or trees. The chances of ordinary people seeing wood dryers are not high.
