box type desiccant dryer Equipment principle

box type plastic desiccant dryer
The air circulation system of the hot air circulation oven adopts a fan circulating air supply method, and the air circulation is uniform and efficient. The air source is driven by a circulating air motor (using a non-contact switch) to drive the wind wheel through the heater to send out the hot air, and then to the oven chamber through the air duct, and then suck the used air into the air duct to become the air source for recirculation. Heating use. Ensure the uniformity of indoor temperature. When the temperature value swings due to the opening and closing of the door, the air circulation system quickly restores the operating state until it reaches the temperature value set by the oven.
The hot air circulation oven is divided into five standard models: one-door bicycle oven, two-door two-car oven, two-door four-car oven, three-door six-car oven, four-door eight-car oven; in addition, Qibao drying can be provided according to customer requirements Non-standard customization.
Most of the hot air circulates in the box with high thermal efficiency and energy saving. The oven uses forced ventilation, and an adjustable air distribution board is installed in the oven to dry the materials evenly. The heat source of the oven can be steam, hot water, electricity, far infrared, and a wide range of options. The whole oven has low noise and stable operation.

Most engineering plastics are hygroscopic. When the plastic is taken out from the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere.
If it is a conventional hot-air barrel dryer, it is Humid external air can dry the plastic, so it cannot prevent the plastic from continuing to absorb moisture.
1. box type desiccant dryer The internal circulation of the dehumidifier: through the operation of the compressor → discharge high-temperature and high-pressure gas through the exhaust port → enter the condenser for cooling → become a low-temperature and high-pressure gas → pass through the capillary tube → become a low-temperature and low-pressure liquid → evaporate and suck through the evaporator Heat → until the compressor becomes a low-temperature and low-pressure gas. So it goes back and forth.
2. box type desiccant dryer The external circulation of the dehumidifier: under normal startup → through the operation of the fan → moist air is sucked in from the air inlet → passes through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → Pass through the condenser to dissipate heat → blow out from the air outlet.
