Single board drying equipment, single board drying equipment, core board dryer, core board dryer

Purpose:
Jet roller dryer is the main production equipment in veneer planing production plants, veneer rotary cutting production plants, and plywood production plants of wood deep processing enterprises. It is suitable for the production process of first cutting and then drying, especially for veneer drying with a thickness between 0.3MM-3.6mm.
Features:
This machine adopts multiple production processes and advanced electronic control frequency conversion technology, therefore it has the characteristics of energy saving and good drying quality.
Working principle of spray roller veneer dryer:
1. Operation system: Planing (rotary) cutting veneers are fed into the feeding port of the air jet roller veneer dryer, and through the relative rotation of several pairs of upper and lower rollers set inside the dryer, the planing rotary cutting veneers move forward in the predetermined direction. During the progress of the veneer, hot air at 110-150 degrees Celsius is vertically sprayed onto the upper and lower surfaces of the veneer with a wind speed of V=1.5m/S through the air jet nozzle set between the two pairs of rollers. Under the control of the electronic control system, the ideal travel speed is adjusted to achieve the drying effect, and the uneven veneer is flattened by the relative rotation of the upper and lower rollers during the movement of the veneer.
2. There are generally three forms of heat media for the air supply of the spray roller veneer dryer:
1) Steam type: High pressure steam with a pressure of 0.1MPA-0.6MPA is directly sent into the SRL type radiator with high thermal conductivity, large heat dissipation area, and stable air jet through the steam pipeline outside the spray roller veneer dryer. The heat energy with a temperature of 110-150 degrees Celsius is exchanged through the heat dissipation aluminum fins on the radiator. Under the action of the high-speed rotating fan, it is sent to the nozzle of the spray roller veneer dryer through the air supply pipeline set inside the machine. Through the spray nozzle, the hot air is sprayed onto the upper and lower surfaces of the running veneer, thus achieving the drying effect.
2) Hot air stove type: The spray roller veneer dryer produced by our factory is specially equipped with an energy-saving hot air stove, considering that users do not have the option to use steam type machines. The working principle of the hot air stove is to burn the waste wood or raw coal produced by the veneer production plant through the hot air stove to generate high temperature. Through the heat exchange plate installed on the hot air stove, the hot air is sent to the spray nozzle installed inside the machine under the action of the high-speed rotating fan. After the spray nozzle is sprayed, the hot air is sprayed onto the upper and lower surfaces of the running veneer, thus achieving the drying effect.
3) Electric heating type: This medium-sized system machine is not energy-saving and is generally not used. 3. Electric control system: The spray roller veneer dryer has a manual control system, stepless variable speed control system, and fully automatic computer control system. It is selected according to customer requirements and adjusts the travel speed based on the thickness and moisture content of the veneer to achieve the drying effect.
4. Moisture removal system: The moisture removal system of the spray roller veneer dryer is achieved through several moisture removal holes set on the machine, controlled by a moisture removal regulating valve, and using the automatic or mechanical moisture removal system inside the machine to achieve the desired moisture removal effect.
5. Sealed insulation system: In order to maximize the drying efficiency of the spray roller veneer dryer, the outer shell of the machine adopts a shell insulation with a thickness of 80MM-100mm to achieve heat inside the machine without losing air volume. Thus achieving a sealing and insulation effect.

The main technical parameters of the spray roller veneer dryer are:
