From farming and food processing to food packaging, automation is ubiquitous in modern food factories. In the food area and splash area, pneumatic technology is mainly used in devices such as dispensing, bottling, forming, filling, dispensing, and sealing. For the food area and washing area, the factory must follow national and international standards and must be cleaned and disinfected frequently. The complete pneumatic device provides a cost-effective option. Applications in food production require specific certifications for air motors, pneumatic air cylinders and other related equipment, as well as special cleaning design features to minimize bacterial retention points.
Pneumatic components are components that perform work through the pressure or expansion of gas, including compressed air cylinders, pneumatic motors, and steam engines.
Pneumatic cylinder actuators are mainly used to complete the actions of selecting, gathering, loading, clamping and unloading, and design and manufacture complex packaging systems. The use of pneumatic technology can greatly simplify the entire mechanism. The working medium is air, and the pneumatic device is a clean power source. For occasions with strict restrictions on pollution, pneumatic cylinder control system is preferred. In the packaging process, multiple actions are often required to coordinate, and the pneumatic components are easy to adjust. Because the pneumatic system has the characteristics of fireproof, explosion-proof, and moisture-resistant, a large number of pneumatic technology is used in the packaging process of some inflammable and explosive products. Practical pneumatic technology is low-cost and easy to adopt.
Compressed air is the main power source and process gas source widely used in equipment in the food industry such as beer, monosodium glutamate, lactic acid, beverages, food fermentation, etc. and other industries. All pneumatic instruments, pneumatic components, cylinders, air solenoid valve, process, and fermentation require compressed air.
However, a large amount of oil-water mixture in compressed air causes great harm to equipment and process gas. There are mainly solid particles—the atmosphere contains a large number of dust and microorganisms, which are sucked into the pipeline by the air compressor and suction filter. The relative humidity in the atmosphere, generally as high as 75% or more, becomes humid saturated air after compression. As the temperature decreases, the water and vapor are transformed into liquid water droplets. In addition, the oil from the connecting rod and piston of the air compressor to the system has undergone many high-temperature oxidation and condensation and emulsification, and the performance of the oil has been greatly reduced, and it is acidic. This will not only fail to lubricate subsequent equipment such as air piston cylinder and pneumatic hydraulic cylinder, but will destroy normal lubrication and cause corrosion.
Therefore, a large amount of compressed and condensed wet saturated air entrains a large amount of liquid oil-water mixture. This is the root cause of the corrosion of equipment, pipes, pneumatic components, cylinders, and valves. It also makes the process and fermentation gas often contaminated by bacteria, which leads to the occurrence of fermentation tanks and other phenomena, causing great losses. Therefore, the study of air source purification has also attracted the attention of experts at home and abroad.
Frequent rotation in an environment with water and dust, 3 port solenoid valve and 4 way solenoid valve are prone to wear. It is easy to rust after shutdown, causing jamming, air leakage, and air leakage.
The valve core of solenoid valve actuator and aira solenoid valve is cast steel. Working in a watery and dusty environment, the valve core and spring are prone to rust or jam, which can easily cause coil ablation and valve failure. .
