Problems solved by technology

[0003] Due to the limitation of its own structure, the existing hot air drying equipment has the heat source circulation mode as upper circulation, lower circulation or other ways. During the drying process, the heat generated by the heat source in the device is transferred, and the material is either from the top to the bottom. Gradually dry or gradually dry from the bottom to the top, not the overall dehydration and drying, the heat energy cannot be fully utilized, resulting in waste
If the amount of dried materials increases, it is easy to cause the materials to not be dehydrated evenly, or even mildewed.

Abstract

The invention provides hot air adjustable double-circulating drying equipment which includes a heating chamber, a material drying chamber and a controller. The heating chamber is internally provided with heating equipment, and the material drying chamber is internally provided with a material rack and a temperature and humidity sensor; the top part and the bottom part of the heating chamber communicate with the material drying chamber correspondingly, and an upper air intake window and a lower air intake window which can be opened and closed are correspondingly arranged on the upper part and the lower part of the heating chamber; an upper moisture discharge window and a lower moisture discharge window which can be opened and closed are arranged on the upper part and the lower part of the material drying chamber correspondingly; the heating chamber is internally provided with a wind guide mechanism that can change the circulation direction of air flow; and the controller is electricallyconnected with a wind guide mechanism, the temperature and humidity sensor and heating equipment correspondingly. The drying time of a material is effectively shortened, the drying uniformity and quality of the material are improved, during the drying process of the material, upper circulation and lower circulation switching operation can be carried out at any time, the degree of automation is high, convenience and fastness are achieved, and time and effort are saved.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a hot air adjustable double-circulation drying equipment. Background technique [0002] Hot air drying equipment is one of the necessary equipment in the field of material drying. It mainly transfers heat from high-temperature heat sources to wet materials in various ways, so that the moisture on the surface of the materials evaporates and escapes to the external space, so that moisture appears on the surface and inside of the materials. Due to the difference in content, the internal moisture diffuses to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed. [0003] Due to the limitation of its own structure, the existing hot air drying equipment has the heat source circulation mode as upper circulation, lower circulation or other ways. During the drying ...
