Many food companies use compressed air, but most are unaware of the damage compressed air quality can do to food safety and quality. Many companies do not include their compressed air systems in their HACCP plans and therefore do not analyze compressed air hazards and establish appropriate control measures. So what are the dangers of compressed air? Let's take a look at the contaminants in compressed air.
Compressed air precision filters are devices that use physical barrier technology to separate other components within a medium. Compressed air filters are the primary equipment used to clean the air by filtering out solid particles, water droplets, oil mist, other aerosol contaminants, and possible microorganisms in the air.
Compressed air supply lines and accessories contaminate air filtered by precision air filters. Measurements show that when you open and close stainless steel valves, there are numbers, dozens, or even more. Therefore, in order to avoid the impact of the compressed air line, in addition to paying attention to the material and maintenance of the line, it is necessary to select the filter with appropriate accuracy according to the length of the line and the pollution situation. Finally, we follow Gaspoint's quality requirements to ensure temperament.
For direct contact with dry food (grains, milk powder, etc.), it is recommended to install a precision filter to ensure control of fine dust, water droplets, oil mist and micro-organisms. If deodorization is required, we recommend adding an activated carbon filter. Others can install the main filter. At the same time, the pressure regulator should be raised to adjust the required air pressure to ensure necessity and safety. For gas connections such as cylinders and solenoid valves, a lubricator should be added to ensure lubrication of gas components.
For non-condensed water, that is, if the dew point criteria are met, it mainly depends on the choice of refrigeration dryer or dryer, normal food contact or non-direct contact uses the refrigeration dryer. For compressed air in direct contact with dry food (cereals, milk powder, etc.) and with strict requirements for micro-organisms, use a refrigeration dryer or a dryer with an exit dew point below 100 °C. -40°C can be selected.
Finally, although different manufacturers call it different, according to the latest technology, each filter has a certain efficiency, but the price varies depending on the origin, but you want to install it once instead of checking it regularly and replacing it. If you use it for a lifetime, it will damage the filter core due to clogging, breakage, deformation, etc. Even if the brand you use is useless (pretending to be safe)... used? How long ago was the exchange?
