Compressed air requirements for the food industry

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.
