Description

Technical Field

[0001] This utility model belongs to the field of pelleting machine ingredient technology, and in particular relates to an anti-sticking device for pelleting machines. Background Technology

[0002] In the pharmaceutical, food, and chemical industries, pelleting machines are essential equipment used to form spherical pellets (pills) from powdered or granular materials. Their operation typically involves multiple stages, including ingredient preparation, mixing, pelleting, and drying. The uniformity and stability of the ingredient preparation stage directly affect the quality of the final product. Traditional pelleting machines generally use simple stirring devices to mix the materials, but this approach presents numerous technical challenges in practical applications.

[0003] First, during the mixing process, some highly viscous or hygroscopic materials are prone to sticking together due to temperature changes or uneven mixing. This residue adheres to the inner wall of the mixing tank or the agitator components, affecting the proportioning accuracy of subsequent batches and even causing fluctuations in product quality. Second, after prolonged operation, the adhered material may clump together, further exacerbating the problem of uneven mixing and increasing the difficulty of cleaning and maintenance, as well as downtime. Furthermore, blockages often occur at the discharge port due to poor material flowability, affecting production efficiency. In severe cases, manual intervention is required to clear blockages, increasing labor intensity and posing operational safety hazards.

[0004] To address this issue, we provide an anti-sticking device for pelletizing machines to solve the problems mentioned above. Utility Model Content
