Process Steam Process steam is used in areas where there is no direct contact with the manufactured product, such as indirect heating. Porvair Filtration Group has a full range of filter grades and materials to achieve the level of filtration required for any process requirement. Culinary Steam Culinary steam is defined by 3A Standard 609-01 as “Steam that is free of entrained contaminants, relatively free of water in liquid form and is suitable for use in direct contact with milk or milk products or product contact surfaces.” In practice this means that the steam filter should be capable of removing 95% of particles 2 microns in size and be manufactured from 300 series stainless steel or higher. Suitable grades are available in sintered metal fibre, mesh and powder for this application. Steam filtration increases system efficiency and protects sterile equipment, removes pipe-scale to prevent fouling of valves or injectors and inhibits contamination of product.
