Wedge wire Mash

A wedge wire support grid provides a false bottom in a lauter tun in many breweries. 

The stainless steel wedge wire screen can be made in sections to fit through a man-way.  The outside of each section is banded with steel bar and lengths of steel strips are supplied to provide a seal between sections. Typically, the screen has .030" to .040" slot openings to hold back the solids and allow liquids to pass through. 

The lauter tun screen sits on a ledge that is positioned on the inside diameter of the tank.  It may also be necessary to have support beams depending on loading and tank diameter.

Example of Lauter Tun screen description
48 3/4" OD made in 3 sections
93V wedge wire on 1/8" x 7/8" support rods at 2" centers
.030" nominal slot openings
3/16" x 1" banding around each section
all 304 stainless steel 

he solids, not the false bottom wedge wire screen, form a filtration medium and hold back  small solids,  allowing  the otherwise cloudy mash to run out of the lauter tun as a clear liquid.
