Product features: It is made of high quality stainless steel. All the corners on the inner and outer surfaces are in arc transition without dead angle and residue. The inner surface is highly polished, the roughness reaches RA ≤ 0.2 μ m, and the outer surface is Matt treated, the roughness reaches RA ≤ 0.4 μ M. The cover is equipped with silicone rubber sealing device to ensure the sealing of the turnover hopper; a special butterfly valve with anti misoperation device is designed to ensure the production safety. It is equipped with special wheels to protect the floor from damage and trace. It fully meets the GMP requirements of drug production. Product application: Mobile silo is the main turnover container in the production process of food and pharmaceutical industry. Materials can be used in the same container for different purposes, so as to achieve frequent processes such as no material transfer and no feeding, and effectively prevent dust and cross contamination. It fully meets the requirements of GMP for drug production. At the same time, through the compact, efficient powder valve design to maximize the protection of operators and products. Economical design, easy installation and manual operation are allowed. It is very suitable for sealing improvement of existing and previous unclosed powder conveying system. At the same time, the investment cost is optimized, and the clean room and PPE (personal protective equipment) are not needed. The products with higher OEL value can be processed to ensure a safe operating environment.
