How to chosse better four sifter for the coversion of the mesh size

Flour sifter is a hand-operated device that allows the baker to turn flour or spices found in the kitchen into fine dusts.

Most flour sifters have a specific mesh size listed on the box. The higher the number, the finer the mesh. A finer mesh means the flour will be finer after sifting, but it also means it will take a lot longer to sift.

The fineness of any sieve or screen depends upon the width of the wire used. The wire used in 10 mesh sieve will be thicker than the wire used in 60 mesh sieve. A thick wire can not make a fine sieve and a thin wire can't make a thick sieve. Fine sieves above 400 mesh, the particle size is describled in microns.

For a material having fine particles, a fine sieve having a very small opening is used. The fineness of any sieve or screen increases when its mesh size increases and its pore size decreases.

Following is the coversion table for the mesh to micron and inch.
