The pharmaceutical industry
1. Air curtains:
In the pharmaceutical manufacturing process, compressed air is used to create air curtains, creating a safe and clean area. Air curtains can be used to isolate different areas, prevent cross-contamination, and control air flow and temperature.
2. Material handling:
In the pharmaceutical industry, compressed air systems can be used for material handling. By using appropriate pneumatic conveying devices, such as pneumatic conveying pipelines and pneumatic conveyors, raw materials, powders, granules, and other materials can be transported from one location to another, achieving efficient, quick, and dust-free handling process.
3. Nitrogen Production:
In the pharmaceutical process, pure nitrogen is often required. By subjecting compressed air to membrane separation technology, oxygen and other impurities can be removed, resulting in high-purity nitrogen used for inert atmospheres, protective atmospheres, and other applications in pharmaceutical processes.
4. Product Drying:
During the pharmaceutical process, some products need to undergo drying to remove moisture or other solvents. Compressed air can be mixed with the product to accelerate the drying process. By providing hot or cold air and coming into contact with the product, compressed air facilitates evaporation and dehumidification, achieving efficient product drying.
5. Process Air:
In the pharmaceutical industry, process air refers to the direct contact between compressed air and products. Process air can be used for cleaning and blowing equipment, inflating containers, driving pneumatic actuators, and various other applications to meet the operational and process needs in pharmaceutical production.
6. Thin Layer Evaporation:
In the pharmaceutical field, thin layer evaporation technology is commonly used to separate substances with low boiling points. This technique utilizes specialized equipment to evaporate and condense the mixture under certain vacuum conditions, achieving the separation and purification of different components.
7. Solvent Recovery:
In the pharmaceutical process, for the purpose of environmental protection and resource conservation, it is necessary to treat and recover solvents from wastewater. Vacuum distillation is one of the commonly used methods for solvent recovery, where low-boiling-point solvent fractions are evaporated and then condensed for recovery. The treated wastewater can be reused in subsequent processes or safely discharged.
