1/2 LINE STRAINER SCREEN

A screen is physical divider intended to block an area from view or to block access.  Screens often provide protection or even filtration and may have holes or perforations allowing air or liquid flow.  A screen may also refer to a "touch screen" which provides a graphical user interface (a display device) which allows the user to interact with a computer or control by touching areas on the screen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.

A mesh strainer, also known as sift, commonly known as sieve, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal. The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate solids from liquid.
