Application of Compressed Air Dryer in Food and Beverage Industry
High requirements for compressed air quality
In the food and beverage industry, the quality of compressed air directly affects the safety and quality of the product. Since compressed air may come into direct or indirect contact with food, there are strict requirements for its purity. Compressed air must undergo multiple stages of filtration to remove particles, moisture, oil and bacteria to ensure that the final gas meets food grade standards. These measures not only protect the purity of the food, but also prevent potential contamination risks, making the production process safer and more reliable.
Precision control of instrument air
In the production process of food and beverages, instrument air is a key link. Compressed air is used to drive various precision instruments and control systems to ensure the automation and stable operation of the production line. Since food production has extremely high requirements for accuracy and consistency, instrument air must have stable pressure and flow to avoid fluctuations that cause production errors. In addition, the cleanliness of compressed air is also crucial for the long-term stable operation of instruments, reducing equipment wear and maintenance requirements.
Application in pneumatic conveying of materials
In the process of pneumatic conveying of materials, compressed air is used to transport powdered or granular food raw materials through pipelines to different processing points. In order to prevent the material from being contaminated during the conveying process, the compressed air used must be strictly filtered and dried to ensure that there are no harmful substances or moisture in the airflow. This link has very high requirements for the quality of compressed air, because any impurities will directly affect the quality and safety of the final product.
High pressure requirements in the bottle blowing process
The PET bottle blowing process is an important application area in the food and beverage industry, especially when producing plastic bottled products. This process usually requires the use of 35-45bar high-pressure compressed air to blow the bottle. Since the compressed air is in direct contact with the internal surface of the bottle during this process, the purity of the compressed air must meet food grade standards to prevent contamination of the inside of the bottle. High-quality compressed air not only ensures the sanitary conditions of the bottle, but also improves production efficiency and product consistency.
Gas application in bottling/canning process
In the bottling and canning process, compressed air is widely used to clean the inside of bottles and cans, drive bottling equipment, and keep the production line clean. Any air entering the container needs to be strictly filtered and sterilized to ensure that the product is not contaminated. This link has particularly strict requirements on the cleanliness of compressed air. The use of unqualified gas may cause food or beverages to be contaminated, affecting product quality and safety.
High standards for packaging inflation and liquid mixing
During the food packaging process, compressed air is used to fill gases such as nitrogen into the package to extend the shelf life of the food and maintain freshness. At the same time, compressed air is also used in the liquid mixing process to ensure uniform mixing and product quality. For these applications, the purity of the compressed air must meet food grade standards to ensure that no contamination sources are introduced. Especially in the packaging inflation process, the use of pure compressed air or nitrogen is crucial to the preservation of food.
successful cases
PD Series Refrigeration Air Dryer
The precooler evaporator and liquid distributor of the PD series refrigerated dryer all adopt an integrated modular structure design.
The PD series dryer adopts a thickened aluminum alloy heat exchanger, and its corrosion resistance is more than twice that of similar products.
SSD Series Refrigeration Air Dryer
Different from carbon steel products, the heat exchanger, water separator and air connection parts are made of 304S stainless steel to avoid secondary pollution to air quality. Therefore, the SSD series dryers can be directly used in food, medicine, semiconductor, advanced spraying and other fields.
