The construction materials themselves are carefully selected. Food grade compressors typically utilize stainless steel and other corrosion-resistant materials for components that come into contact with the compressed air. These materials are non-reactive, easy to clean, and resistant to the growth of bacteria and mold.
Effective air filtration and purification are vital to ensuring that the compressed air is free from contaminants. Food grade systems incorporate advanced filtration systems to remove particles, dust, moisture, and microorganisms. These systems typically include particulate filters to capture solid particles, coalescing filters to remove oil and water aerosols, and activated carbon filters to eliminate odors and organic vapors.
Air dryers play a crucial role in removing moisture from the compressed air, which can support the growth of microorganisms and negatively affect product quality. Desiccant air dryers and refrigerated air dryers are commonly used in food grade applications to achieve the required level of dryness. Desiccant dryers use a desiccant material, like silica gel, to absorb moisture, while refrigerated dryers cool the air to condense the water vapor.
Air receivers are often integrated into a food grade air compressor system. These tanks store compressed air, which helps stabilize the pressure and provide a buffer for fluctuations in demand. Properly sized air receivers ensure a consistent air supply, reducing wear and tear on the compressor and improving overall efficiency.
