Roller veneer dryers is designed to dry core dry press plywood , hardwood veneer plywood and other plywoods with the jet box and the pressing feed rolls. Roller dryer machine has the advantages of simple operation, safety and practicality, stable operation and easy maintenance ,hot pressing-leveling-drying are finished at the same time &and others.The use of hot air circulation has greatly reduced the operating costs of enterprises, improved the quality of sheet materials and increased the production volume. The roller plays a role in ironing the veneer. After the veneer is dried by veneer dryer, the veneer is flat and the moisture content is relatively uniform.The dryer machine can effectively use various resources and occupy a small area.The roller dryer machine can be divided into two parts: heating section and cooling section.The heat medium can be oil and heat steam. Our company developed and produced biomass combustion machine for boiler and thermal oil furnace, can burn all kinds of biomass fuel. which can reduce the combustion cost of heating equipment greatly.The biomass burner developed and produced by our company is suitable for boilers and hot oil furnaces, which can burn various biomass fuels.Can greatly reduce the heating equipment combustion cost.

Roller Veneer dryer is one of the main equipment in plate production. The quality of veneer drying directly affects the quality of veneer and glued products. The design of hot air continuous roller press is based on the most advanced continuous pressure contact veneer drying technology in the world. The working principle is that the veneer is clamped by the upper and lower seamless steel tube rollers, and the oven temperature reaches 140 ℃ by preheating, and then enters between the upper and lower rollers and lows high pressure hot air to the upper and lower sides of the veneer through the hot air pipe for rapid drying. So it can make the veneer smooth and moisture content even after drying, and it also has the characteristics of direct contact heat transfer between high temperature roller and wet veneer, high thermal efficiency, low heat loss and reducing heat energy consumption.
1. After drying, the veneer is smooth and the moisture content is uniform, and the high temperature drum has direct contact with the wet veneer for heat transfer, and the heat efficiency is high, the heat loss is small, and the heat loss is reduced.
2. The equipment adopts frequency conversion to adjust feed speed according to your veneer thickness and moisture content to achieve ideal drying effect.
3. The equipment covers a small area, less ancillary equipment, convenient transportation, quick installation, and can be put into use quickly.
4. Each section with heat exchanger, which can make full use of the heat and achieve the best drying effect.
5. All the fans are with converter motor, which can guarantee the service life of the dryer.
