Compressed air needs to meet a series of strict standards in terms of food grade requirements to ensure food safety and hygiene. The following is a detailed summary of the food grade requirements for compressed air:
1. purity requirements
compressed air must be free of oil, water, dust and other contaminants. Specifically:
the oil content should be less than 0.1 mg/m & sup3;, to ensure that the compressed air does not contain oil, to avoid food pollution.
The water content should be lower than a certain standard, such as 7ppm or pressure dew point to -40 ℃, to prevent the adverse effects of moisture on food.
The particle size should be less than 0.01 μm (microns) to ensure that the compressed air is free of dust and other solid particles.
2. Odor and Taste Requirements
compressed air should have no peculiar smell and no bad taste to avoid adverse effects on the flavor of food. This usually means that the odor level in the compressed air should be below a certain standard, such as 0.5.
3. microbiological control requirements
the microbial content in compressed air should be controlled within a safe range to prevent microbial contamination of food. Specifically, the number of bacteria should be less than 100 CFU/m & sup3; to ensure food hygiene and safety.
4. other requirements
in addition to the above requirements, food-grade compressed air also needs to meet the following standards:
the pH value should be between 6.5 and 8.5 to ensure that the pH of the compressed air is moderate and will not cause corrosion to the food or affect the quality of the food.
It should have constant pressure and flow to ensure the stability and consistency of the food processing process.
In summary, the requirements for food-grade compressed air include high purity, no odor, low microbial content, and other specific physical and chemical indicators. Together, these standards ensure the safety and hygiene of compressed air during food processing. Please note that different regions and enterprises may have their own standards and testing methods, so they need to be implemented according to local regulations.
Answer: The twin-screw air compressor performs well in many aspects, with high mechanical reliability, excellent dynamic balance, smooth operation and strong adaptability. In addition, the twin-screw air compressor overcomes the single-screw air compressor.
According to international standards and industry norms, the oil content of compressed air in contact with food shall be strictly controlled by grading. The specific standards are as follows: 1. direct contact with food scenes (such as ingredients, fermentation and stirring) International standard: ISO 8573-1:2010 Class 1: Oil content ≤ 0.0
There are many hidden dangers in the air compressor, which are not only related to the safety performance of the equipment itself, but also related to the safety and health of the operators. The following are some of the main safety hazards: 1. the safety hazards of the equipment itself Explosion risk: Lubricating oil mixing: Atomized
There is a close correlation between different gas demand and gas supply pipe diameter. In the design and configuration of the gas supply system, we must fully consider the specific needs of gas, in order to select the appropriate gas supply pipe diameter, to ensure the efficient and stable operation of the system. Generally speaking, gas
The requirements for atmospheric pressure in precision plants are mainly based on the need for precision and stability in the production process. The following is a detailed summary of the atmospheric pressure requirements for precision factories: 1. stability requirements: precision factories need a constant atmospheric pressure environment to ensure
The air compressor room is like a gas "kitchen", its main function is to "cook" the compressed air or gas we need. In this special room, multiple air compressors are neatly arranged, just like opening
The use of large oil-free air compressor is quite extensive, mainly due to the characteristics of its compressed air does not contain oil. The following are some specific application areas: Electronics industry: oil-free air compressors can continuously provide clean compressed gas to meet the requirements of the electronics industry for zero
In PCB (printed circuit board) factories, the type of air compressor depends on the specific needs and configuration of the factory. Generally speaking, PCB factories will choose to use oil-free air compressors, mainly because of the high requirements for the purity of compressed air. In the PCB production process,
Whether the air compressor can be turned on all the time is really a somewhat complicated question! Just like us, although we can work continuously, we will definitely feel tired without rest for a long time. For the air compressor, although technically it can run continuously, but for a long time
Air compressor belongs to the compressor manufacturing industry in the machinery industry. In addition, since the air compressor is also a kind of general machinery, it can also be classified as an electromechanical equipment pneumatic control industry. In various industries, automotive, construction, power and chemical industry is the main air compressor industry.
