Q: National standard food industry requirements for compressed air?
A: Oil-free compressed air.
The following are the compressed gas standards for the food industry:
indirect contact;
bottle blowing, packaging, etc. The quality of compressed air shall meet the following ISO8573.1-2010 standards:
grade of solid particles: Grade 2
water content level: 4
oil content grade: Grade 2
direct contact with dry food;
for example, grain, milk powder, compressed air is used for transportation and mixing, and usually also for food production.
It comes into direct contact with food. Because these are dry foods, there are more stringent requirements in terms of air humidity.
ISO 8573-1:2010 applies to compressed air in direct contact with dry foodstuffs-Quality requirements:
-Solid particles: Grade 1
-Water: Level 2
-Oil: Grade 1
non-dry food contact;
for example, beverages, meat, vegetables, compressed air is used for transportation and mixing, and usually also for food production.
It comes into direct contact with food.
ISO 8573-1:2010 Quality requirements for direct contact of non-dried foodstuffs with compressed air:
-Solid particles: Grade 1
-Water: Level 4
-Oil: Grade 1

Comparison of Scroll Air Compressor and Screw Air Compressor Scroll Air Compressor and Screw Air Compressor are commonly used air compression equipment in the industrial field, and they have their own advantages and applicable scenarios. Advantages of scroll air compressor: compact structure: scroll air compressor usually
In industrial production, the percentage of moisture content in the air is a crucial parameter, which directly affects the stability of the production process and the quality of the product. The water-lubricated screw air compressor produced by Shanghai Granklin Group is characterized by its excellent dehumidification capacity and pure
Oil-free air compressor needs to be tested. Testing is essential to ensure the performance, safety and operating status of oil-free air compressors. The following is a detailed explanation of the oil-free air compressor testing requirements: the necessity of testing performance guarantee: through regular testing, can be timely
The main basis for the national oil-free standard for compressed air is ISO 8573-1. According to this standard, the highest grade of oil-free compressed air, Class 0, requires an oil content of less than 0.01 mg/m & sup3;. This is the main indicator to measure whether compressed air is oil-free.
When the air inside the air compressor contains moisture, it can be removed by the following methods: 1. the physical drainage method, use the drain valve to install the drain valve at the bottom of the cooler or air storage tank of the air compressor. Regularly open the drain valve to drain the moisture accumulated at the bottom of the equipment
Whether the air compressor belongs to special equipment depends mainly on its specific purpose and parameters. Generally speaking, according to the definition of the Special Equipment Safety Law, special equipment refers to equipment that involves life safety and is more dangerous, such as boilers, pressure vessels, and pressure pipelines.
Granklin oil-free screw water-lubricated air compressor: the "environmental protection guard" of air purification In the pursuit of efficient and environmentally friendly industrial production, Granklin oil-free screw water-lubricated air compressor has become the first choice for many enterprises with its unique technical advantages. This is empty.
Hospital air compressor room is an important part of hospital facilities, mainly for the hospital to provide a variety of medical equipment required by the compressed air. The following are the main functions of the hospital air compressor room: to provide power for medical equipment: the air compressor is the main production of compressed air
The pressure requirements of a plant air compressor depend on a number of factors, including the production process, the type of equipment and the job requirements. The following is a summary of some common factory air compressor pressure requirements: General industrial use: In most industrial production fields
The main reason why semiconductors require oil-free compressed gas is that any grease can contaminate the chip, which in turn affects the performance and reliability of the product. In the semiconductor chip manufacturing process, oil-free compressed air is required to ensure the cleanliness of the production environment
