What is the principle of plastic desiccant dryer?
Dehumidification drying: the hot and humid air from the drying barrel is cooled and blown into the honeycomb wheel. The moisture in the air to be runner adsorption, then re heating air desorption students. The role of the two streams at the wheel, and along with the rotation of the rotary wheel, the moisture in the air even continuous adsorption desorption regeneration air is discharged, the formation of stable low dew point air heated to plastic dry drying temperature, drying into the material barrel, to form a closed circulation the raw material, drying.Suction: suction is sucked from the storage tank or other storage container in dry material barrel when the magnetic reed switch to detect vacuum hopper feeder, material suction motor running, the vacuum vacuum hopper, material storage barrel of raw materials due to the air pressure difference is sucked into the vacuum hopper when, suction time after suction motor stops running, the raw material will fall into the dry material barrel due to weight. After drying the raw material from the drying material barrels pumped to the installation in the hopper plastic molding machine in the electric eye.
We first ordinary drying machine, dryer using electric heating hot air to the ordinary space material in high temperature drying, moisture evaporation materials. The purpose of electric heating of the air inlet is in air. In the dry weather and wet weather, the water in the air rate is not the same. So when wet weather conditions. There will be incomplete, material drying phenomenon. Because the first electric heating air intake air, but in the air contains high moisture material, how to dry thoroughly? (mainly reflected in the high moisture absorption rate of the material, such as nylon).To this end, dehumidificator came into being. In view of this situation above, the ambient air pumping in the removal of water in the air at the low dew point, and then the drying of the material dryer air heating input is relatively dry.Therefore, the difference between the two drying machines is that the moisture content in the air inlet is different from that used in the drying process. One has treated the incoming air moisture, and the other has no water treatment for the inlet air
A dehumidifier in circulation: gas discharge, high temperature and high pressure through the exhaust port of the compressor to run into condenser cooling, low temperature and high pressure gas into a liquid, and through capillary closure, into the low temperature and low pressure evaporator to compressor through endothermic back into low temperature and low pressure. So cycle.External circulation two, dehumidifier: in normal circumstances, through the operation to fan the moist air from the air inlet through the evaporator, the evaporator will be inhaled, moisture adsorption on the aluminium to become dry air through the condenser, cooling, blown out from the air outlet.
