Lauter Tun Screens
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

2*4mm wedge wire on 3*5mm support bars(The wedge wire and support bars according to the application and the size of the screen)
0.76mm slot, usually the slot according to clients' request
Bandings bar arround each section, and some bearing bar help to improve the strength.
All Stainless Steel 316L material, 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.
