A continuous automatic drying device and method

Abstract

The invention provides a continuous type automatic drying device and method, and belongs to the technical field of heating and drying. The device comprises a burdening part, a collection part, a drying body part, a heating part and a control part. The burdening part comprises a feeding conveyor belt and an inlet flow regulation plate. The collection part comprises a discharging conveyor belt and afinished product collection bag. The drying body part comprises a drying rotary drum and a seal box. The heating part comprises a heating source, a conveying pipeline, a circulation system and a moisture discharge system. The control part comprises a detection unit, a drive unit and a control unit. To-be-dried raw materials are conveyed to the drying body part from the burdening part; by means ofreal-time control of the control part, the heating part conducts drying; and the dried materials are collected through the collection part. The continuous type automatic drying device and method caneffectively meet the requirement for conducting dynamic material turnover on the dried raw materials in the drying process through an existing drying device, the overall drying effect can be effectively improved, and the unit time output rate can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of heating and drying, in particular to a continuous automatic drying device and method. Background technique [0002] The drying device is widely used in the drying treatment of vegetables, fruits, traditional Chinese medicine, agricultural and sideline products, etc. The commonly used one is the mesh belt dryer, which passes the material to be processed through an appropriate spreading mechanism, such as a distributor, a swing belt, Grinders or granulators are distributed on the conveyor belt, and the conveyor belt passes through a channel composed of one or several heating units. The main heating methods can include electric heating, steam heating, and hot air heating. Each heating unit is equipped with air heating and Circulation system, each channel has one or several dehumidification systems, when the conveyor belt passes, hot air passes through the materials on the conveyor belt from top to bottom or ...

AI Technical Summary

Problems solved by technology

According to statistics, there are about 100 kinds of drying devices that have been actually developed and applied, but most of the drying devices are still unable to solve the demand for dynamic turning over of drying raw materials during the drying process, and the volume change before and after drying is relatively small. Large raw materials cannot be automatically stacked and merged with the drying process, which affects the drying effect and the output rate per unit time of the drying equipment to a certain extent, and is not conducive to the improvement of the overall efficiency.
