Papel Veneer Drying Lines for Veneer plant
Beech veneer is light yellow, with clear texture and uniform texture. The density of beech is generally about 790kg/m³, and the hardness is about 5800N. The rear beech veneer has a smoother surface. Because it is cooking, the moisture content reaches %50-%60, and the moisture content is relatively high. If the moisture content of the veneer after drying reaches %0-%14, it takes about 10 minutes, so if the output of beech veneer drying is If there are requirements, special optimization of the dryer is required. MINGHUNG MH-RD2830L; MH-RD304HL These two models are veneer drying equipment optimized for beech veneer. For details, please contact us.
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.
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.
Veneer drying parts:
FAN:
We have professionally designed according to different types of dryers, positive pressure fans and negative pressure fans, different fans for different veneer drying equipment, energy-saving, high-efficiency design concepts provide an effective guarantee for improving the quality of veneer drying products .
MESH AND ROLLER:
HEAT CONDUCTION HEAT SINK:
Heat conduction heat sink, used for MINGHUNG veneer drying, the warp is made of aluminum, the characteristics of aluminum material is good heat conduction effect, low heat loss, can better improve heat conduction efficiency, internal design forced circulation, heat conduction effect is better than traditional heat dissipation Warp increased by %70. Greatly improved energy utilization.
