WORKING PRINCIPLE

Brief introduction about the operation principle of air energy mesh belt dryer

The mesh belt drying equipment uses hot air as the drying medium. The hot air generated by the air energy heat pump is sent to the drying box through a centrifugal fan to dry the material, the processed material is conveyed by multi-layer stainless steel mesh belt. After several times of loop flip through the layers in the drying box, the hot air is introduced into the dryer by the fan. The wind speed and wind pressure generated by the induced draft fan make the hot air fully and evenly released at the bottom of the dryer. As the lower pressure is greater than the upper pressure, the hot air moves upward and passes through the mesh belt and material layer from bottom to top, which makes the material fully contact with the hot air and could be dried layer by layer.

Machine components:

1.Integrated machine:itcontrols the start and stop bottom of the drying room, and controls the temperature, humidity and dehumidification time of the drying room. It also provides heat energy for drying material.

2.The warehouse with polyurethane sandwich board:itprovides heat preservation for materials in the drying room.

3.Centrifugal ventilators: it provides wind energy for the materials to bring out the moisture in the materials. It also brings out the heat energy in the main engine to make the drying room heat up or cool down.

4.Material conveyor belt: After the material has been put on the conveyor devices evenly, it will be transmitted to the mesh belt of the dryer.

1.Test condition: the temperature of outdoor dry bulb is 25°C, the temperature of air inlet dry bulb is 25°C, while the air outlet dry bulb is 60°C.

2.The dehumidification amount is calibrated under standard test conditions and will be different due to the temperature changes between indoor and outdoor wet bulb.

3.Models, parameters, and performance will be changed due to the product improvements. The specific parameters are subject to the product nameplate.
