Closed-type normal temperature drying equipment

Abstract

The invention discloses closed-type normal temperature drying equipment. The closed-type normal temperature drying equipment comprises a drying box and a generation box, a partition plate is arrangedin the generation box, and partitions the generation box into a first cavity and a second cavity, the first cavity is connected with the drying box through a pipeline, and the first cavity is connected with the second cavity by forming air inlet holes in the partition plate; air in the generation box and the drying box can be circulated through a pipeline, a mechanism capable of lowering the relative humidity of air in the drying box is arranged in the first cavity, and the second cavity is internally provided with a second condenser capable of heating and cooling the air. Through the second condenser, the air can be kept at normal temperature. Through the arrangement, the closed-type normal temperature drying equipment can have low energy consumption, to-be-dried articles can be dried atnormal temperature, the quality of the dried articles is guaranteed, and articles which are sensitive to the temperature can be dried. Besides, by means of the drying mode, no harmful gas is producedin the drying process.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a closed normal temperature drying equipment. Background technique [0002] Drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. [0003] For example, the invention patent of Chinese Patent Publication No. CN107883735A discloses a powder material quick-drying dryer, which includes a drying bin, and is characterized in that the drying bin is a vertical cylindrical structure, and the lower end of the drying bin is provided The feed port, the opening of the feed port is set at an angle of 45° upward, the other end of the feed port is connected to the material delivery pipeline, the bottom of the drying bin is provided with a large fan, and the upper...

Problems solved by technology

[0004] The above technical solution mainly uses the thermal effect of infrared rays to heat and dry the dry items, but this technical solution will cause the local temperature of the pipeline to be too high, and the heat in the high-temperature gas will be dissipated to other low-temperature gases, resulting in part of the waste of energy. If the temperature is too high, it will easily lead to changes in the structure of the dried items, which will affect the quality of the dried items
