Working Principle of Veneer Dryer

1. Operating system:

The planed (rotary) veneer is fed from the feed port of the wind-jet roller type veneer dryer, and through the relative rotation of several pairs of upper and lower rollers inside the dryer, the planed and rotary-cut veneer is rotated in the predetermined direction. Front running, during the veneer traveling process, the hot air of 110-150 degrees Celsius is vertically sprayed to the upper and lower surfaces of the veneer at the wind speed of V=1.5M/S through the air nozzle installed between the two pairs of rollers. Under the control of the electronic control system, the most ideal speed is adjusted to achieve the best drying effect, and the uneven veneer can be ironed during the relative rotation of the upper and lower rollers. Effect.

2. The hot air of the jet roller veneer dryer obtains the form of heat medium:

External biomass combustion furnace, built-in combustion furnace, hot blast stove type: the air-jet roller veneer dryer produced by our factory is specially equipped with an energy-saving and high-efficiency hot blast stove considering that the user does not have the choice of a steam-type machine , the working principle of the hot blast stove is to burn the waste wood or raw coal from the veneer production plant through the hot blast stove to generate high temperature, and under the action of the high-speed rotating fan inside the machine, the hot air is sent to the air nozzle in the machine. After the powerful spraying of the air nozzle, the hot air is sprayed onto the upper and lower surfaces of the running veneer, so as to achieve the drying effect.

3. Electric control system: The frequency conversion control system of the wind-jet roller veneer dryer adjusts the speed according to the thickness and moisture content of the veneer to achieve the most ideal drying effect.

4. Moisture drainage system:

The dehumidification system of the jet roller type veneer dryer is through a number of dehumidification holes on the machine, and through the regulation of the dehumidification regulating valve, it adopts the automatic dehumidification system or the mechanical power dehumidification system in the machine. , in order to achieve the best dehumidification effect.

5. Sealed insulation system:

In order to exert the best drying performance of the wind spray roller veneer dryer, the shell of the machine adopts a shell with a thickness of 75MM-100MM for heat preservation, so as to achieve the heat inside the machine without losing the air volume. So as to achieve the best sealing and heat preservation effect.
