Belt drier

Abstract

The invention relates to the field of drying equipment, in particular to a belt drier used for materials such as foods, traditional Chinese medicine, dehydrated vegetables and the like. The belt drier comprises a feeding system, a distributing system, an inlet air filtering system, a heating system, a main machine, a material drive system located in the main machine and the like, wherein a cleaning system is further arranged in the main machine and comprises a cleaning water pipeline and a compressed air pipeline; the cleaning water pipeline comprises water inlet pipes located at the upper part of a bottom net belt and drain pipes located at the bottom of the main machine. According to the belt drier, the cleaning system comprising the cleaning water pipeline and the compressed air pipeline is added, thorough cleaning after materials are dried by the drier is realized, and the cleanness of the drier is sufficiently guaranteed, so that the phenomenon of cross contamination due to the fact that various materials are dried by one drier is avoided, and the diversified requirement for drying various materials by one drier is met.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a belt dryer used for materials such as food, traditional Chinese medicine and dehydrated vegetables. Background technique [0002] Belt dryer is a continuous drying equipment widely used in chemical industry, food, medicine, building materials and other industries. It is used for drying flake, strip, granular or block materials with good air permeability, especially for dehydration. It is especially suitable for materials with high water content and strict drying temperature requirements such as vegetables and Chinese herbal medicines. With the continuous improvement of the technical level, the belt dryer has gradually become diversified. However, none of the belt dryers currently on the market have a cleaning system, so one dryer can only dry one material. If one material is dried and then other materials are dried, if the cleaning is not clean, there will be problems. Cross-c...

Problems solved by technology

However, none of the belt dryers currently on the market have a cleaning system, so one dryer can only dry one material. If one material is dried and then other materials are dried, if the cleaning is not clean, there will be problems. Cross-contamination, especially for the drying of traditional Chinese medicine and food, requires high environmental cleanliness, and a little carelessness will cause life-threatening; while manual cleaning has defects such as high labor intensity, poor cleaning effect, and low efficiency.

[0003] With the needs of the market, the requirements of traditional Chinese medicine companies for drying equipment for Chinese medicinal materials have shifted to equipment with higher production capacity and automation requirements. Belt dryers have become the first choice for enterprises. The shape varies greatly and is extremely irregular, and many Chinese medicine companies have encountered thorny feeding problems, that is, feeder blockage, uneven cloth distribution, etc., which seriously affect production efficiency and increase production costs.

In addition, the existing Chinese herbal medicine drying equipment is directly supplied to the material distribution system through the conveyor belt feeding system for material distribution. There is no buffer storage device for wet material, and uniform feeding cannot be achieved, resulting in uneven distribution of traditional Chinese medicine wet material on the internal mesh belt of the dryer. Uniformity, resulting in poor uniformity during drying, resulting in differences in the moisture content of Chinese herbal medicines, affecting product quality
