Pneumatic conveying of clean powder is a frequently used weight operation process in the production of raw materials and preparations in pharmaceutical industry. Because the solid powder and preparation particles of API often have drug activity, and many flammable, explosive and volatile substances are used in the process of drug production. At the same time, as the pharmaceutical industry has higher and higher requirements for the production environment, people pay more and more attention to the application of pneumatic conveying technology of clean powder.
Manual handling and mechanical transportation will cause problems such as direct contact between operators and materials, materials exposed to the environment, dust flying and so on, which pose a great threat to the requirements of clean production environment and the safety of workers. In addition, it is easy to generate static electricity in the transportation process, which can easily lead to pipeline blockage and wear of transportation equipment.
In recent years, in order to ensure the health and safety of workers and the clean requirements of the workshop environment, a new type of material transportation system transportation method has emerged. Under the premise of not reducing the original performance of the process equipment, this method can fully realize the closed link and prevent dust leakage and flying. The system transportation method mainly includes container docking system (CDS) and powder transportation system (PTS). It is especially suitable for the high aseptic production and sensitization process.
CDS can realize loading, unloading, batching, crushing and sampling under closed conditions, especially suitable for the production process of API or high active API. It can effectively protect the staff and production environment, avoid cross infection, and finally optimize the material transportation process. PTS is suitable for the transportation of clean powder under the condition of 100000 grade. The suction and discharge time can be controlled flexibly. One machine can be used for multiple sets of equipment in turn. It is easy to install and operate, and can be used in an explosion-proof environment with solvent and dust. It can provide a fully clean and dry conveying environment for the powder materials which are easy to oxidize, hygroscopic and heat sensitive, and can effectively solve the particle stratification and electrostatic phenomenon.
Domestic pharmaceutical companies for conveying materials to the tank and flammable, explosive, volatile solvent reaction method is to directly fill the tank with protective gas, so as to reduce the oxygen content in the tank and reduce the risk of explosion. Because the material will carry a certain amount of oxygen when entering the tank, and the friction between the materials will produce static electricity, so in a strict sense, this method can not completely eliminate the potential explosion hazards. The PTS vacuum conveying equipment adopts inert gas protection device, which can effectively ensure that the protective gas in the vacuum silo is at a positive pressure relative to the gas in the original tank, and can block the combustion risk from the root, so as to prevent the leakage and explosion of volatile solvent.
