The solid particle grade of compressed air in the food industry usually follows the relevant international or national standards. Among them, ISO 8573-1 is an international standard on the purity level of compressed air, which specifies the maximum allowable content of solid particles, water and oil. For food plants, a purity grade of ISO 8573-1:2010 Class 1.2.1 or higher is usually required, which means that the maximum size of solid particles should be less than or equal to 0.1 microns (μm).
In addition, there are other standards and guidelines related to compressed air in the food industry, such as the food processing guidelines issued by the US FDA (Food and Drug Administration), emphasizing that compressed air must be free of harmful substances and will not contaminate food. The European Hygienic Engineering Group (EHEDG) also provides guidelines for the hygienic design and operation of food processing equipment, including compressed air systems. In China, there are also corresponding food safety regulations and standards, such as the national standard (GB) on food contact materials and equipment hygiene requirements, these standards may indirectly affect the design and operation of compressed air systems.
In summary, the solid particle level of compressed air in the food industry should reach a certain purity standard to ensure that the compressed air does not contain harmful substances and meets the food use standards. Specific solid particle grade requirements may vary from region to region and from business to business and will therefore need to be implemented in accordance with local or business specific regulations.
The replacement cycle of the air compressor filter element needs to be comprehensively determined according to the three elements of operating conditions, environmental cleanliness, and filter element quality. The following are specific guidelines: 1. routine replacement cycle Use scenarios Air filter element Oil filter Oil separator
The air compressor is not always pumping. The work of the air compressor is cyclical. It will stop pumping when the set pressure limit is reached, and start pumping again when the pressure drops to the set lower limit. This mode of operation is to maintain the pressure in the gas tank.
The oil-free screw air compressor compresses air through a two-stage screw rotor, and removes water in the compressed air through a water-gas separator. At the same time, because there is no fuel injection cooling, a pre-cooler, an intercooler, and an after-cooler are generally configured to cool the compressed air to meet the requirements.
Requirements for Cleanliness of Compressed Air in Pharmaceutical Industry and Adaptability of Water Lubricated Single Screw Air Compressor 1. Core Requirements for Cleanliness of Compressed Air in Pharmaceutical Industry Pharmaceutical production requires extremely strict cleanliness of compressed air. It is necessary to ensure that the air quality conforms to the drug production specifications and avoid
The main difference between oil-free piston air compressors and oil-injected air compressors is reflected in their working principle, lubrication method and the quality of the compressed air produced. Oil-free piston air compressor: working principle: oil-free piston air compressor through the piston in the cylinder
The atmospheric pressure in the industrial field is usually based on standard atmospheric pressure (Standard Atmospheric Pressure), and its value is 101325 Pa sascals (Pa). The following is a detailed description based on physical principles and industrial practice: 1. core values and unit conversion standards
The maintenance of oil-free air compressors mainly includes the following aspects: Regular replacement of the filter element: The filter element is an important component of the air compressor and is used to filter impurities and pollutants in the air. In order to maintain the quality of the compressed gas and protect the internal parts of the compressor, it is necessary
The air compressed by the air compressor usually contains moisture, which may cause damage to the equipment using the air. Therefore, gas water removal is a very important part of the air compressor system. The following are some air compressor gas water removal methods: cooling method:
Trouble phenomenon: When the engine is running and the air compressor is inflating the air tank, the air pressure indicator indicates that the air pressure cannot reach the starting pressure value. Causes of failure: 1. The barometer fails. 2. The transmission belt between the air compressor and the engine is too loose and slips, or
As an important equipment in industrial production, the danger of air compressor is mainly reflected in the following aspects: 1. explosion danger internal failure or unreasonable design: heat will be generated in the process of air compression. If the compressor fails or the design is unreasonable, the heat cannot
