After more than a month's production, 12 sets of 100 cubic cubic aluminum alloy drying kilns have finally been shipped, thanks to the customer's trust

(1) The start of the drying room. Close the inlet and exhaust ducts; start the fans. For a reversible circulation drying room with multiple fans, start the fans one by one. Do not start several fans at the same time to avoid overloading the circuit; open the valve of the bypass pipe of the steam trap and open it slowly. Heater, to make the heating system heat up slowly and discharge the air, water and rust in the piping system at the same time, when a large amount of steam is ejected from the bypass pipe, then close the valve of the bypass pipe and open the steam trap valve to make the steam trap work normally .

1. Preheating treatment: First, the control system only opens the steam injection valve, and preheats by steam injection through the evaporation water tank in the kiln. The dry bulb temperature (Td) and the wet bulb temperature (Tw) in the kiln rise synchronously. The rapid 3-hour steam injection makes the drying medium in the kiln reach Td = Tw = 9 0 ℃ or more. Then, depending on the thickness of the dry sheet, keep it for different times to preheat the sheet.

Thermal modification of wood: heating the wood, resulting in a certain degree of degradation of the wood components, resulting in the desired improvement of the wood properties

The end of the wood is dried first due to the rapid evaporation of water. When the moisture of the end is lower than the fiber saturation point, the end cells begin to shrink. When the dry shrinkage stress reaches the strength limit of the wood, end cracking occurs.

Production units usually use the gravimetric method and the electrical measurement method

Convective drying of wood in gaseous medium.There are two cases: 1. When the moisture content is lower than the fiber saturation point. 2. When the moisture content is higher than the fiber saturation point.

Carbonized wood is a modified product of high temperature heat treatment of wood. Compared with ordinary wood, it has a series of characteristics:

The dimensional stabilization of wood is a treatment method to change its hygroscopic and hygroscopic properties without destroying the complete structure of the wood cell wall.
