Infrared air exhaust and pressure reduction material-drying device

Abstract

The invention discloses an infrared air exhaust and pressure reduction material-drying device comprising a tank body than can be enclosed inside. An infrared lighting source emits infrared to the inside of the device. The tank body that can be enclosed is connected with an air exhaust and pressure reduction assembly. Material requiring drying is disposed in the tank body that can be enclosed. Under the irradiation of the infrared, the internal water molecules of the irradiated substance can generate resonance energy because of absorption of the infrared and the temperature of the irradiated substance rises. The heating management of the irradiated substance is controlled through intensity of illumination of the infrared and interval of on-off irradiation time. The material requiring drying is heated to a predetermined temperature and achieves specific vacuum pressure through air exhaust and pressure reduction via communication of a vacuum pump pipeline together with the tank body that can be enclosed, so that the boiling temperature of the water can be reduced to be below the specific temperature according to physical characteristics and the internal water molecules of the substances can vaporize through boiling. Vaporized moisture can be exhausted during the air exhaust and pressure reduction. The infrared air exhaust and pressure reduction material-drying device is formed by the tank body, which can be enclosed and can employ the vacuum pump for the air exhaust and pressure reduction, and the infrared lighting source.

Description

technical field [0001] The invention relates to a drying method for materials in the shape of particles, powders, flakes, etc., especially refers to a sealable tank that can be pumped and decompressed and equipped with a light source that can emit infrared rays, so that the wet The undried material is decompressed and heated to produce a drying effect. Background technique [0002] At present, most of the drying devices for plastic granules on the market use electric heaters to heat the air to generate hot air, and then use hot air to bake the undried plastic granules to dry them. The effect of using it to dry undried plastic particles is limited; after that, a dehumidification device is added to the hot air flow air. The filter body provides a high-temperature heater to evaporate the inhaled water, but the disadvantage is that the structure of the device is complicated and the cost is high, and the sieve-type water-air filter body is gradually decomposed into powder and po...
