What are the pressure and flow requirements of compressed air?

Pharmaceutical industry compressed air pressure and flow requirements and water lubrication single screw air compressor suitability description

compressed air pressure requirements for 1. pharmaceutical industry

the demand for compressed air pressure in pharmaceutical production varies with the process, and the adaptation range needs to be selected according to the actual scenario:

1. conventional pharmaceutical process compressed air pressure is usually set between 0.5 ~ 1.0MPa, which can meet the basic needs of equipment drive and pipeline purging.
2. High cleanliness process for example, in the production of sterile preparations, the pressure of the instrument air supply system shall be stabilized at 0.5~0.7MPa to ensure the accurate operation of pneumatic instruments; Some special processes may require the pressure to reach 0.8~0.95MPa.
3. biological fermentation process compressed air needs to be in direct contact with the fermentation liquid, and the pressure requirement is low, usually between 0.2~0.4MPa(2 ~ 4bar), but it needs to be continuously and stably supplied to avoid affecting the fermentation effect.

Compressed air flow requirements for 2. pharmaceutical industry

flow requirements are closely related to production scale, number of equipment and process complexity:

1. small pharmaceutical companies: For single equipment or small-scale production line, the flow demand is about 5~10m & sup3;/min.
2. Medium-sized pharmaceutical companies: Multiple production lines are running in parallel, and the flow demand may reach 20~50m & sup3;/min.
3. Large pharmaceutical companies: The whole process is automatically produced, and the flow demand may exceed 50m & sup3;/min, multiple air compressors need to be configured to operate in parallel.

Adaptability of 3. Water Lubricated Single Screw Air Compressor in Pharmaceutical Field

the water-lubricated single-screw air compressor of this enterprise realizes gas compression through the meshing of single screw and star wheel piece, and its technical characteristics are highly compatible with the needs of the pharmaceutical industry:

1. pressure and Flow Adaptability:
   • the rated exhaust pressure range of the equipment covers 0.7~1.0MPa, which can be flexibly adjusted to meet the needs of different processes.
   • Flow rates range from a few cubic meters per minute to tens of cubic meters per minute, supporting full-scale coverage from small to large pharmaceutical companies.
2. Zero Oil Pollution Risk:
   • the use of water lubrication technology to replace traditional lubricants, completely avoid the risk of cross-contamination of drugs caused by oil pollution, in line with GMP (Good Manufacturing Practice for Pharmaceuticals) requirements for the clean production environment.
3. Efficient drying performance:
   • during the compression process, the water is discharged in time through the drainage device, and the post-processing equipment (such as freeze dryer and adsorption dryer) can stably reach the pressure dew point below -40 ℃, meeting the strict requirements of the pharmaceutical industry on the air dryness.
4. Energy saving and stability:
   • intelligent frequency conversion control technology can automatically adjust the power according to the amount of gas used to reduce energy consumption; water lubrication design reduces component friction, prolongs equipment life, and ensures long-term stable operation.

4. application cases and effects

the water lubricated single screw air compressor has been successfully applied to many pharmaceutical enterprises, covering the whole process from the production of raw materials to the preparation processing:

1. sterile preparation workshop: The pressure of compressed air is stable at 0.7~0.8MPa, the flow rate meets the operation requirements of multiple filling equipment at the same time, and the microbial limit is ≤ 1 CFU/m & sup3; To ensure the sterility of drugs.
2. Solid preparation production line: The moisture content is controlled at a very low level through post-processing equipment, and the flow rate is adapted to the requirements of tablet presses, coating machines and other equipment to prevent moisture absorption and agglomeration of materials and improve product quality.
3. Biological fermentation workshop the compressed air pressure is stable at 0.3MPa, the flow rate meets the intake demand of the fermentation tank, and the zero oil pollution characteristic avoids the pollution of the fermentation liquid and improves the purity of the product.

5. Summary

the enterprise water lubrication single screw air compressor through innovative water lubrication technology, for the pharmaceutical industry to provide zero oil pollution, efficient dry compressed air solutions. Its pressure and flow range can be flexibly adapted to the needs of pharmaceutical enterprises of different sizes, and its technical characteristics are highly compatible with the requirements of pharmaceutical production, which can help enterprises to improve product quality and meet the requirements of industry standards.
