A sanitary stainless steel strainer-in-line filter is a piece of equipment that removes unwanted particles from process lines. They are used in many industries, including food and beverage, dairy, meat and poultry, cosmetic, and pharmaceutical.The principle of stainless-steel sanitary working of a  filter involves separating solids from liquids or gases by passing them through a porous medium. Sanitary strainers are made with perforated plate screen mesh that removes larger particles, while filters use disposable media to capture fine particles. The mesh is designed in many sizes and shapes, and is either woven or welded together. Stainless steel is a good choice for straining because it is more corrosion and abrasion resistant than brass, and can hold up to daily cleaning. Sanitary strainers can be placed inline or as a side-inlet. They help protect downstream critical equipment from tear and wear, ensure safe operation, and meet sanitary requirements.
