The working capacity of the heat pump dryer is related to the environment in which it is used. After one year of continuous use, the interior of the heat pump dryer unit may become dirty and the working capacity will decrease. Therefore, special equipment inspection and equipment maintenance must be carried out. For this kind of inspection and maintenance work, it is recommended that you contact the heat pump dryer manufacturer or its maintenance department. Users should pay attention when using and maintaining this unit: all safety protection devices in the unit are set before leaving the factory, and do not adjust it by yourself. .

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.

After several months of unremitting efforts, the African Cameroon company signed a cooperation agreement with our company.

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

Wood drying is the process with the largest energy consumption in the processing of wood products. In my country, wood drying accounts for 40%-70% of the total energy consumption. Therefore, the energy saving of the drying process becomes particularly important. The current drying methods (using moist air as the medium) include: atmospheric drying, conventional room drying, dehumidification drying, solar drying, vacuum drying, etc.

The wood dryer equipment is a large-scale equipment with various operations, and the safety issues in the production process of the wood dryer should be taken seriously. Production must be safe, and safety can lead to normal production. In the general environment, when safety and production conflict (such as personal and mechanical), the first thing to obey is safety

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

Carbonized wood is a wood that is subjected to short-term pyrolysis modification treatment at a temperature of 180°C to 250°C in order to improve the dimensional stability and durability of wood in an environment that blocks oxidation and hydrolysis reactions.

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:
