In the pharmaceutical industry, the humidity control of compressed air is very important because it directly affects the quality and safety of pharmaceutical products. The humidity standard of compressed air for pharmaceutical use usually involves two aspects of relative humidity and moisture dew point, and the specific requirements are as follows:
the relative humidity of the compressed air in the pharmaceutical production workshop should be kept within a certain range to avoid affecting the production of drugs. In general, this range is in 40% to 60% between.
the moisture dew point is the temperature at which the water vapor content in the compressed air reaches saturation. In the pharmaceutical industry, the dew point temperature of compressed air has strict requirements to ensure the dryness of compressed air. Specific requirements are as follows:
In addition, the humidity and moisture dew point of compressed air are divided into different levels according to GB/T 13277.1-2023 Compressed Air Part 1: Pollutant Purification Levels. For example, the dew point temperature value of level 2 compressed air should be ≤-40 ℃, which is equivalent to the water vapor content ≤ 127.34ppmv.
in the pharmaceutical process, if the humidity of the compressed air is too high, it may cause the following problems:
Therefore, pharmaceutical companies must strictly control the humidity of compressed air to ensure that the dryness of compressed air meets the requirements of relevant standards.
in order to ensure that the humidity of the compressed air meets the standard, pharmaceutical companies can take the following measures:
In summary, the humidity standard of compressed air for pharmaceutical use involves two aspects of relative humidity and moisture dew point, and the specific requirements should be determined according to the production process and quality requirements of the drug. Pharmaceutical companies must take effective measures to strictly control the humidity of compressed air to ensure the quality and safety of drugs.
Technical recommendations on the setting of the discharge pressure of the air compressor The setting of the discharge pressure of the air compressor needs to be comprehensively considered in combination with the specific application scenario and equipment characteristics, and its core principle is to achieve optimal energy efficiency on the premise of meeting the process requirements. The following from the technical regulations
Description of the dew point of compressed air in the pharmaceutical industry The dew point is a key indicator to measure the moisture content in compressed air. It refers to the temperature at which the gas is cooled to the temperature at which water vapor begins to condense into liquid water. The lower the dew point, the lower the moisture content in the compressed air. Pharmaceutical Industry Pressure
There are still many processes for vegetable processing, and compressed gas is needed in many places. We can look at the process. According to the basic production process of dehydrated vegetables and the characteristics of vegetable varieties, it is generally divided into leaf vegetables pre-dehydration treatment production line.
The requirements of fermentation for sterile air mainly include the following aspects: Sterility: The air used in the fermentation process must be sterile, which means that the air cannot contain microorganisms, such as bacteria, molds, and yeasts. This is to avoid microbial contamination
There is a significant difference in volumetric efficiency between screw and scroll compressors. The following is a detailed comparison of the volumetric efficiency of the two compressors: Definition and scope of volumetric efficiency of 1. screw compressor: volumetric efficiency refers to the actual gas delivery and management of the compressor
In the process of using the screw air compressor, some factories will have insufficient gas supply. In fact, the selection of the machine, air leakage, gas production standards, machine wear and other aspects may produce insufficient gas supply, resulting in the production workshop equipment can not operate normally.
The compressed air quality standards generally used in factories mainly include the following aspects: Oil content: The oil content in compressed air is usually required to be low to avoid pollution to equipment and processes. In general, the oil content should be less than 5mg/m3. Moisture content
Air compressors are widely used in industry. The following is a summary of their main uses: Power source for pneumatic tools: Air compressors can provide power for various pneumatic tools, such as pneumatic wrenches, pneumatic drills, spray guns, etc. These tools are used in industrial production
The performance test standards for oil-free air compressors involve many aspects. These standards are designed to ensure the performance, quality, safety and reliability of air compressors. The following is a detailed analysis of the performance test standards for oil-free lubricating air compressors: 1. to the international standard ISO 8573-1:
Screw air compressor motor speed varies according to equipment type and application scenario, the following is a detailed answer: 1. speed range standard national standard According to GB/T standard, the motor speed of screw air compressor is divided into two gears: 2-pole motor: synchronous speed 3000rpm, actual air compressor
