Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of granulation equipment. Specifically, it relates to a granulation equipment and process for hepatoprotective and liver-nourishing medicated and edible homologous drugs for treating alcoholic liver disease. Background Art

[0002] Alcoholic liver disease, as a liver lesion caused by long-term excessive drinking, has seen a sharp rise in the prevalence rate globally in recent years. With the acceleration of the modern life rhythm and the frequency of social activities, the consumption of alcohol continues to grow, and alcoholic liver disease has become a public health problem that cannot be ignored. Among the treatment plans for alcoholic liver disease, hepatoprotective drugs play a core role. Among them, medicated and edible homologous drugs are highly favored in clinical applications and research due to their natural, low-toxic, and few side effects advantages. In the preparation process of medicated and edible homologous drugs, granulation is a crucial step. Extruders are widely used in the drug granulation process due to their strong plasticity and high-efficient material handling ability. With the cooperation of an extruder and a pelletizing device, various drug raw materials can be precisely processed into pellets with specific shapes and particle size distributions. Then, the pellets are transported to a dryer through a conveying device for drying and collection. However, since the water content of the pellets is relatively high after cutting, the pellets are prone to sticking to each other and aggregating into larger lumps during the transfer to the dryer, thus affecting the drying effect of the pellets and easily affecting the pellet quality due to uneven drying.
