Veneer Drying For Plywood Sheets
Veneer drying
Veneer drying is very important for the production of plywood. After wood is produced into veneer through veneer lathe, the moisture content is 50-70%. Plywood production requires veneer moisture content of 8-%14. The moisture content of veneer is greater than %14, which brings negative The influences are: 1. It will increase the hot pressing time of the plywood blank in the hot press.
The heating of the hot press is heated by a steam boiler or a heat transfer oil boiler. If the hot pressing time is increased, it is equivalent to an increase in heat loss. 2. If the moisture content is higher than %14, the veneer after glue spreading will seep out of glue during the hot pressing process, causing the plywood to crack. 3. If the moisture content of the veneer is 14%, the plywood blank needs to be dehumidified several times during the hot pressing process to remove the moisture inside the plywood blank.
If the temperature is not properly controlled, there will be air bubbles in the semi-finished plywood, which will crack and cause the plywood to be scrapped.
MINGHUNG veneer drying effectively solves the problem of veneer drier, veneer drying, according to the density of different veneers, the customer's different veneer output, the factors of purchasing cost, MINGHUNG has developed a variety of veneer drying types MH-RD40L,MH-RD304HL / MH-2830L / MH-MD3618 : roller veneer dryer, wire veneer dryer, mesh veneer drier, press drying, square tube veneer drying, Hollow veneer drier, ect specialized in research on saving energy, energy consumption and improving production efficiency of veneer drying.
