Which link in dairy production uses compressed air

In dairy production, compressed air is widely used in many key links, as follows:

1. raw material handling and transportation

• milk pump drive: During the milk collection phase, compressed air is used to drive the milk pump to quickly and safely draw fresh milk from the cow to the milk storage tank. This process not only improves the collection efficiency, but also reduces the contact between milk and air, reducing the risk of contamination.
• Pipeline transportation: Compressed air is also used for pipeline transportation of liquids, such as milk, soy sauce, purified water, etc., to ensure the smooth flow of raw materials on the production line.

2. production and processing process

• equipment cleaning sterilization equipment, filling machines, pipes, containers, bottles and other tools and machines in the dairy factory need to be cleaned and discharged with high-pressure compressed air to remove dirt and bacteria and ensure the hygiene and safety of the equipment.
• Stirring and mixing: Compressed air is used to stir the milk to distribute its ingredients evenly, thereby improving product quality. Compressed air is also commonly used to mix and stir ingredients in the batching process to ensure uniformity and consistency.
• Injection gas in the production of milk products, compressed air can also be used to inject gas into milk to make drinks such as milk foam. By compressing the air into high-pressure gas and injecting it into the milk, the bubbles in the milk can be made smaller and more uniform, thereby improving the taste and quality of the milk.

3. packaging and storage

• drive packaging machinery: Compressed air provides power for packaging machinery to ensure that food is properly sealed and stored. In the aseptic packaging process, sterile air is used to prepare pressure to prevent external air and bacteria from entering the interior of the package.
• Maintain positive pressure in milk tank: In the storage process, compressed air is used to maintain the positive pressure in the milk storage tank, prevent external air and bacteria from entering, and ensure the freshness and safety of milk.

4. other auxiliary applications

• pneumatic tools and equipment compressed air is also used to drive pneumatic tools and equipment in dairy plants, such as pneumatic agitators, pneumatic handling systems, etc., to improve production efficiency.
• Cooling and freezing in some cases, compressed air is also used in refrigeration systems to maintain the temperature required for food storage.
