Description

Technical Field

[0001] The utility model relates to the technical field of spray drying, in particular to a spray drying device for traditional Chinese medicine extracts. Background Art

[0002] Spray drying is a drying method that uses an atomizer to disperse the raw material liquid into droplets and uses hot gas (air, nitrogen or superheated steam) to dry the droplets to obtain the product. The droplet group has a large surface area, so the drying time required for the material is relatively short.

[0003] At present, during the use of spray drying equipment for Chinese herbal medicine extracts, it is unable to automatically adjust the drying temperature of the Chinese herbal medicine extracts during spray drying according to the spray amount of the Chinese herbal medicine extracts, the material temperature of the Chinese herbal medicine extracts, the air volume of the drying hot air and the air temperature of the drying hot air. If the drying temperature is too low, the Chinese herbal medicine extracts cannot be completely dried, while if the drying temperature is too high, the extracts are easily damaged. Therefore, we propose a spray drying equipment for Chinese herbal medicine extracts. Utility Model Content

[0004] The purpose of the utility model is to provide a spray drying device for Chinese herbal medicine extracts, which has the advantage of automatically adjusting the drying temperature of the Chinese herbal medicine extracts during spray drying according to the spray amount of the Chinese herbal medicine extracts, the material temperature of the Chinese herbal medicine extracts, the air volume of the drying hot air and the air temperature of the drying hot air during the spray drying process of the Chinese herbal medicine extracts, thereby ensuring that the Chinese herbal medicine extracts achieve the drying effect while avoiding damage to the Chinese herbal medicine extracts. It solves the problem that the current spray drying device for Chinese herbal medicine extracts cannot automatically adjust the drying temperature of the Chinese herbal medicine extracts during spray drying according to the spray amount of the Chinese herbal medicine extracts, the material temperature of the Chinese herbal medicine extracts, the air volume of the drying hot air and the air temperature of the drying hot air during use, that is, when the drying temperature is too low, the Chinese herbal medicine extracts cannot be completely dried, and when the drying temperature is too high, the Chinese herbal medicine extracts are easily damaged.
