Description

Technical Field

[0001] This utility model relates to the technical field of drying and pulverizing devices, and in particular to a device for mixing, drying and pulverizing thick pastes. Background Technology

[0002] Thick pastes are a common material form in traditional Chinese medicine, food, and chemical industries. They are typically formed from raw materials through extraction, filtration, and concentration processes. They are viscous, have a high water content, and contain various active ingredients or effective substances. To meet the needs of subsequent processing, storage, transportation, and use, thick pastes require pulverization and drying. On the one hand, drying removes excess moisture, reducing the risk of mold and spoilage and extending shelf life. On the other hand, pulverization transforms the dried thick paste into a uniform fine powder, facilitating subsequent mixing, formulation, and dissolving processes, thereby improving product production efficiency and quality stability.

[0003] In existing technologies, the drying uniformity of thick paste mixing, drying, and pulverizing devices is generally insufficient. The hot air inlet and outlet layouts of some devices lack optimization, making it difficult for hot air to form a uniform circulating airflow within the device. This results in limited airflow coverage and uneven flow rates. Simultaneously, some areas of the thick paste remain in hot air dead zones for extended periods, while other areas are excessively swept. This leads to significant differences in the moisture evaporation rate across different parts of the thick paste, resulting in localized areas that are thoroughly dried while others still contain a large amount of moisture. This not only affects the consistency of product quality but also necessitates repeated re-drying, significantly reducing drying efficiency. It is impossible to simultaneously perform high-quality pulverization and uniform, high-quality drying operations, failing to meet the requirements of industrial continuous production for drying uniformity and efficiency. Therefore, we propose a thick paste mixing, drying, and pulverizing device to solve the above problems. Utility Model Content
