Wedgewire Mash / Lauter Tun Screens

A wedgewire 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
59 3/4" OD made in 5 sections
93V wedgewire on .074" x 3/4" support rods at 1 1/2" centers
.030" nominal slot openings
1/8" x 1" banding around each section
four -.074" x 1 1/2" seal strips (shipped loose)
all Type 304 stainless steel 

The solids, not the false bottom wedgewire 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.
