What is the preheating process of hf timber dryer
The hf timber dryer manufacturer tells you the advantages of timber drying equipment. The main accessories are imported and specially designed blowers and axial fans. It has the advantages of high temperature resistance, corrosion resistance, moisture resistance and energy saving. The equipped steam generator can produce a large amount of atmospheric steam. The manufacturer of hf timber dryer tells you that the various systems of wood drying can be flexibly adjusted according to the drying process of the wood, which solves the defects of internal cracks, end cracks, surface cracks, deformation, discoloration and so on. During the wood drying process.
At the same time, it can completely kill all the moths and eggs that are parasitic in the wood, and solve the bad effects caused by the moths. The manufacturer of hf timber dryer tells you that the heat recovery device equipped with wood drying realizes the full use of the drying medium, greatly reduces the drying cost, and improves the economic benefits of the enterprise.
Pre-heat treatment of hf timber dryer: The pre-heat treatment time should be determined according to the type, thickness and moisture content of the wood. For example, a material with a thickness of 5 mm should first be sprayed for 12-15 hours. In order to obtain a reasonable temperature gradient, the cooked material needs to be processed for 6 to 8 hours.
These two higher-density materials (such as parenchyma cells and ray parenchyma cells), mahogany, patty, and dry eight buckets, are generally sprayed for 24 hours to soften the wood, dredge the cell cavity, and partially dissolve the cell cavity. Filling, to prepare for the subsequent drying process. The manufacturer of hf timber dryer tells you that the initial spray temperature should not be too low, otherwise the steam flowing into the furnace is too small, making the relative humidity in the furnace not up to the benchmark requirement, and the pre-heating effect is not good. Generally, the initial treatment temperature is 95-10oC.
The manufacturer of hf timber dryer tells you whether the fan starts continuously during the initial treatment of wood drying depends on the airtightness of the furnace body. If the furnace body is well sealed, it can be started continuously after the first spray for 3-4 hours; the manufacturer of hf timber dryer tells you if the furnace body The sealing performance is poor, and the furnace body is continuously started for a long time, the temperature in the furnace will increase, and the humidity will decrease, resulting in drying defects during the initial treatment. In this case, it is generally turned on once every 2 to 3 hours, so that the steam is evenly dispersed on the surface of the material, and a good treatment effect can be obtained.
