If the rear negative pressure dust removal and moisture removal device cannot control the air volume well, it is easy to cause the material temperature to drop rapidly and cause part of the tobacco aroma to be lost. For example, in the flavoring process, the characteristics of the design of some brands of products have a large flavoring ratio and the material is in the process of absorbing the essence. If the rear negative pressure dust removal and moisture removal device cannot control the air volume well, it is easy to cause part of the essence on the material to be lost, affecting the sensory quality of the product. Second, it is impossible to perform automatic adjustment according to the characteristics of the product brand and the process requirements to meet the needs of flexible process processing. Third, the integrated structural design makes it difficult to disassemble the cover, tube body, filter and other components, which is not conducive to internal cleaning and maintenance. Fourth, the pressure and load borne by a single device are large, and the process cannot be adjusted in time. If equipment failure or abnormality occurs, it is easy to affect the entire production process and the quality of the final product. Utility Model Content
