Eliminate the problem of plywood opening caused by veneer drying
Veneer drying is an important part of plywood production. Veneer drying is used for plywood sheets. The quality and drying efficiency of veneer after drying directly determine the quality and output of plywood.
How to know the quality of the veneer after drying by the veneer dryer?
Low veneer shrinkage the temperature in the drying room of the dryer is too high, which will cause the veneer to form a dew point in an instant.the shrinkage of the veneer will increase. If the shrinkage is too large, it will cause uneven glue coating during the veneer coating process, and breakage will occur during the tissue culture process, resulting in defects in the production quality of the plywood.
2. The moisture content of the veneer is uniform, and the heat conduction of the veneer dryer is uniform, which can make the surface of the veneer generate dew point at the same time.moisture inside the veneer dissociates to the surface of the veneer at the same time.after the veneer is dried, the tax rate will be uniform.
3. The veneer has no cracking and no fracture，for the drum veneer dryer, if the drum pressure is too large, the shrinkage of the veneer due to water evaporation during the drying process is too large, and if the veneer is too large due to the drum pressure at the same time, the veneer will break.
MINGHUNG veneer dryer solves the problems that arise during the veneer drying process of the dryer
Veneer drying is a very important link in the production process of plywood. The moisture content of veneer is too high, or the moisture content of veneer is uneven, which directly affects the production quality of plywood. Usually, the moisture content of veneer is required to be %8-%14 , the moisture content of the veneer in this interval is the most reasonable for the quality of the plywood veneer, so a veneer dryer is required to complete the veneer drying. The selection of the veneer dryer needs to provide us with several data to ensure that we provide the best solution:
1. What is the thickness of the veneer?
2. What is the throughput for 10 hours?
3. What is the moisture content of the veneer?
4. The name of the tree for the veneer?
5. Is the heating boiler heat transfer oil or steam? Etc., MINGHUNG MH-304HL model dryer, providing energy-saving and efficient veneer drying solutions.
What is a veneer dryer?MINGHUNG Roller veneer dryer for drying original wood veneer, remove abundant humidity, in the end, the wood veneer humidity will be 5%-10%, so it is suitable for making plywood.Veneer roller dryer are suitable for big drying capacity per day, it can be different length, width
