The strainer is used as a filter for impurities both in the form of solid, liquid or gas. This filter is used in pipelines to filter out impurities in the flow so that the flow to be processed or the process results are of better quality. A strainer is a wire-mesh silicone or metal kitchen sieve that chefs and home cooks use to separate liquids from fine solids in cooking, often in situations where small solids or pieces of sediment (like tea leaves or fruit seeds) require finer filtration.
