Power supply for pneumatic equipment: In the food production process, many devices such as pneumatic conveyors, pneumatic filling machines, and pneumatic packaging machines rely on compressed air as their power source. Air tanks store compressed air to ensure a stable supply of power, enabling these devices to operate smoothly and improving production efficiency. For example, in a biscuit production line, pneumatic conveyors transport biscuit blanks, and air tanks provide the necessary compressed air to ensure the continuous operation of the conveyors.
Ingredient transportation: Air tanks can be used in combination with pneumatic conveying systems to transport powdery, granular, or small piece ingredients. Compressed air in the air tanks creates pressure to push ingredients through pipelines from one processing station to another, achieving efficient and hygienic transportation. In a flour mill, for instance, air tanks are used to convey flour from the storage area to the mixing area for further processing.
Packaging and filling: During the packaging process of food products, air tanks play a crucial role. They supply compressed air for filling machines to precisely control the filling volume and speed. In the case of bottled beverages, air pressure from the air tanks is used to push the beverage into the bottles at a constant rate, ensuring accurate filling and consistent product quality.
Cleaning and sterilization: Compressed air from air tanks can be used for cleaning food processing equipment and production lines. High-pressure air can blow away dust, debris, and residual food particles, maintaining a clean production environment. Moreover, in some cases, sterilized compressed air can be used for sterilization purposes, helping to eliminate harmful microorganisms and ensure food safety.
Controlling the atmosphere in food storage: In the storage of some fresh foods, air tanks can supply different gases to adjust the gas composition in the storage environment. For example, by filling nitrogen from air tanks into food storage rooms or packaging, the oxygen content can be reduced, slowing down the oxidation and spoilage process of food and extending its shelf life.
Driving air-operated valves and actuators: In food processing plants, air-operated valves and actuators are widely used to control the flow of materials and the operation of equipment. Air tanks supply compressed air to drive these components, enabling precise control of the production process. For example, in a dairy processing plant, air-operated valves control the flow of milk in the pipeline, and the air pressure required for the operation of these valves is provided by air tanks.
