The industrial continous face core veneer dryer produced by Shandong Shine Machinery Co., Ltd. is widely used in flatting drying of high-grade plywood, multi layer board and architectural core face veneer. the face core veneer dryer is equipped with environmental protection type hot air stove. its characteristics: save fuel, twice use of hot air , increase heating speed.the veneer after drying is flat,moisture content is up to national standard. Equipped with integral type high efficiency energy saving hot air stove. No boiler and other auxiliary equipment, no use water,coal, electricity. Rind ,wood chips and wood craps are all can be as fuel. and can quickly achieve the heat required by the face core veneer dryer.the face core veneer dryer is mainly composed of the following sections:
1.Drying system:the face veneer dryer adopts the most scientific drying principle ,and the hot air in the hot air stove is injected directly into the upper and lower bellows of the machine by centrifugal blower. The hot air blows to the upper and lower sides of the running veneer through the nozzles of the upper and lower bellows , so that the veneer is heated evenly and thus plays the role of drying
2.Control system: adopt endless gearbox to adjust feed speed according to your veneer thickness and moisture content to achieve ideal drying effect.
3.Transmission system:the veneer is fed into the machine through the feed inlet vertically, and the chain drives the upper and lower rows of rollers, running relatively. The veneer moves forward by the self-weight pressure of the upper roll, and during the veneer passes through the two rollers and the upper and lower air nozzles, it achieves the effect of drying and ironing. So the veneer dried by this machine is flat, smooth and without marks.
4.Heating system: Steam heating, heat conduction oil heating, hot stove type heating，waste wood or other biomass materials. Users can choose one

Roller face 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 blows 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.
