A belt dryer

Abstract

The invention relates to the technical field of drying equipment, in particular to a belt type drier. The belt type drier is characterized in that the drier comprises a drying box, a conveying net belt arranged in the drying box, heat exchangers arranged in the drying box, a plurality of partition plates, air flue assemblies and hopper assemblies, wherein a feed inlet and a discharge outlet are formed in the two ends of the drying box in the length direction; the multiple partition plates are uniformly arranged in the drying box in the length direction of the drying box, the inner space of the drying box is divided into a plurality of drying units through the partition plates, the multiple drying units comprises the multiple first drying units and the multiple second drying units, and the first drying units and the second drying units are sequentially arranged in the direction from the feed inlet to the discharge outlet; the air flue assemblies are arranged at the tops of inner spaces of all the drying units in a one-to-one correspondence mode; the hopper assemblies are arranged at the bottoms of the inner spaces of all the drying units in a one-to-one correspondence mode. The belt type drier has a good drying effect, raise dust is effectively prevented from being produced, the yield is increased, the material recovery rate is increased, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a belt dryer. Background technique [0002] The belt dryer is especially suitable for dehydrated vegetables, Chinese herbal medicines and other materials with high moisture content and heat sensitivity. It has the advantages of high drying rate, high evaporation intensity and good product quality. Belt dryers are widely used in industry and are mainly used for drying small pieces of materials and fibrous materials. In short, the material dried by the belt dryer must have a certain shape, and it must still maintain a certain shape after drying. [0003] Belt dryer is a continuous drying equipment widely used in chemical industry, food, medicine, building materials and other industries. It is especially suitable for materials with high water content and strict drying temperature requirements, such as dehydrated vegetables and Chinese herbal medicines. With the continuo...

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.

[0004] In addition, belt dryers on the market generally have problems such as poor sealing effect, small powder escaping and affecting the production environment; bottom hoppers are inconvenient to collect materials, etc.

[0005] Since the temperature of the dried material is basically 60~80°C, the material needs to be cooled for the convenience of packaging. The belt dryers on the market do not have a good cooling solution, and the cooling speed will be too slow or even the material will return to moisture.
