Compressed air in the food industry such as beer, monosodium glutamate, lactic acid, beverage, food fermentation and other industries in the equipment is the main power energy and process gas source, all pneumatic instruments, pneumatic components, cylinders, solenoid valves, process, fermentation need compressed air. So what are the requirements of the food industry for compressed air quality?
In the food and beverage industry, it is necessary to use compressed air to control the valves and braking devices in the automatic production line of filling, packaging and bottling. The conveying, blowing, ventilation, fermentation, cooling and spraying of powdery substances also need completely pure compressed air.
Once the compressed air contains oil or other impurities, it will cause pollution. In the food industry, any small pollution may bring hidden dangers to consumers. According to the requirements, the level of compressed air in the food industry must reach the level 2 standard, and the dew point of compressed air is below -40°C.
How to make the compressed air quality meet the requirements of the food industry?
First of all, the compressed air must be purified. The compressed air purification system includes air compressors, air storage tanks, filters, dryers and other equipment; compressed air that has not been purified contains water, oil, particles, dust and other pollutants. Direct use in food production will cause damage to pneumatic components, pollution of food, and decline in enterprise competitiveness; compressed air purification equipment mainly refers to dryers and filters, choosing the right dryer and filter is the key to purifying compressed air!
Freeze dryer
commonly used dryers on the market are () and (). As the pressure dew point theory of cold dryers can only reach +2 ℃-+10 ℃, it cannot meet the requirements of the food industry for compressed air quality. Common adsorption dryers include modular adsorption dryers and mold core adsorption dryers. The pressure dew point can generally reach -20 ℃ -70 ℃. Enterprises can choose the right adsorption dryer according to their own gas demand. The pressure dew point of Beiteng mold core dryer can reach below -40 ℃, which fully meets the gas requirements of the food industry.
Filters generally choose high-efficiency precision filters, the role is to filter compressed air in the oil, dust and solid particles and other impurities, filtration efficiency of up to 99.99, filtration accuracy: 0.01 μ.
The drainage operation of the screw air compressor can be carried out through the following steps: manual drainage method: close the air compressor and release the pressure: tighten the drainage valve. Shut down the oil pump. Turn the relief valve knob counterclockwise to release the inside of the reservoir
As an important equipment in the industrial field, the quality of the screw air compressor is directly related to the production efficiency and the service life of the equipment. Among many brands, the water-lubricated screw air compressor produced by Shanghai Granklin Group stands out for its excellent quality and performance.
The difference between power frequency air compressor and permanent magnet air compressor is mainly reflected in energy efficiency, noise, maintenance cost and functional characteristics. The following is a detailed comparative analysis: 1. energy efficiency: the energy efficiency of the power frequency air compressor is relatively low. due to its motor turn
The maintenance cycle of the air compressor and the parts that need to be replaced vary depending on the type of equipment, working environment, frequency of use, and manufacturer's recommendations. The following are some general maintenance intervals and parts replacement guidelines: 1. maintenance intervals Daily inspection: inspection
Whether the air compressor can run continuously for 20 hours a day depends on a number of factors, including the type of air compressor, the working environment, the load situation and maintenance. The following is a detailed analysis of this problem: Air compressor type: Different types of air compressors have
The frequency of screw air compressor refueling depends on a number of factors, including equipment model, conditions of use, type of lubricant, and manufacturer's recommendations. The following are some general guidelines for screw air compressor refueling cycles: 1. regular refueling cycles New
Oil-free air compressor mainly means that no lubricating oil is used in the compression chamber of the compressor for lubrication. Such compressors are commonly referred to as oil-free air compressors. Specifically: the meaning of oil-free: "oil-free" is used to describe the compressor
Screw machines and scroll machines each have their own advantages and applicable scenarios. It is impossible to simply say which is better to use, but needs to be selected according to specific application requirements and scenarios. The following is a detailed comparison of the two: In terms of efficiency, screw machines: usually have higher efficiency, especially in
The continuous operation of the air compressor may be caused by a variety of faults. The following are some common causes and corresponding solutions: common faults and causes of leakage in the gas circuit system: when there is leakage in the gas circuit system, such as loose gas pipe joints, lax valve sealing, etc., empty
Oil-free silent air compressor and oil-free air compressor have their own advantages, which is better depends on the specific application needs and preferences. The main advantage of an oil-free silent air compressor is that the compressed air it provides does not contain oil, which is necessary for those who need high-purity air.
