In the pharmaceutical industry, high-pressure compressed air plays a vital role in many production processes and equipment. The following are the main areas where high pressure compressed air is required:
1. Liquid preparation production
- filling machine in the production process of liquid preparations, the filling machine often uses high-pressure compressed air to complete the filling operation of the liquid medicine. High-pressure compressed air provides a stable power source for the filling machine to ensure that the liquid medicine can be filled into the container accurately and quickly.
2. Solid preparation production
- granulator, pulping machine, filling machine, packaging machine, printing machine in the production line of solid preparations, these equipment often use high-pressure compressed air to assist in the completion of their respective process operations. For example, a granulator may use compressed air to transport materials or control temperature; a filling machine may use compressed air to control the filling speed and accuracy of tablets.
3. Extraction process
- extraction tank in the extraction process of traditional Chinese medicine or natural medicine, the extraction tank often uses high-pressure compressed air to assist in the extraction and separation of medicinal materials. This helps to improve extraction efficiency and product quality.
4. Other uses
- test pilot gas in the process of drug development and quality control, high-pressure compressed air is often used as a trial gas in laboratory tests to meet the gas needs of various precision instruments and equipment.
- Material conveying, drying and purging: In the operation of material conveying, drying and purging in the pharmaceutical workshop, high-pressure compressed air also plays an important role. It helps to ensure the cleanliness of the production environment and the accurate delivery of materials.
- Pneumatic instrument and automatic control gas: In the automatic control system of the pharmaceutical workshop, high-pressure compressed air is often used as the power source of pneumatic instruments and automatic control equipment to ensure the stability and reliability of the production process.
5. Quality standards
- pressure range the compressed air pressure required by pharmaceutical companies is usually between 0.5-1.0MPa. This range is based on the actual needs of pharmaceutical equipment and processes, and is designed to ensure the stability and efficiency of the production process.
- Other quality standards in addition to pressure, compressed air must meet other quality criteria such as low oil content and suitable humidity. The Chinese Pharmacopoeia and GMP require that the oil content of compressed air be less than or equal to 0.1 mg/m & sup3;, and even some require that the oil content should be less than 0.01 mg/m & sup3;; Humidity is usually required to be lower than 50% to avoid adverse effects on drug production.
In summary, high-pressure compressed air is widely used in many aspects of the pharmaceutical industry. In order to ensure the quality of compressed air and the stability of the production process, pharmaceutical companies need to pay close attention to the pressure changes and quality standards of compressed air, and take necessary measures to control and adjust.
