A belt dryer

Abstract

The present invention relates to the field of drying equipment, in particular to a belt dryer used for food, traditional Chinese medicine and dehydrated vegetables and other materials. The material transmission system located in the main machine, etc., is also equipped with a cleaning system in the main machine. The cleaning system includes a cleaning water pipeline and a compressed air pipeline; the cleaning water pipeline includes a water inlet pipe located on the upper part of the bottom mesh belt and a drain pipe located at the bottom of the main machine. The invention adds a cleaning system composed of a cleaning water pipeline and a compressed air pipeline to realize the thorough cleaning of the drying machine after the materials are dried, and fully guarantee the cleanliness of the drying machine, thereby avoiding the need for a variety of materials to be processed by a single drying machine. The phenomenon of cross-contamination caused by drying meets the diverse needs of a dryer that can dry a variety of different materials.

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
