Lauter Tun Screen


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

Product Details

The lauter tun, a traditional brewing vessel, has undergone significant evolution over time. While its primary function remains unchanged - to separate extracted wort from solids - modern advancements have elevated the design of lauter tuns to new heights, enabling quicker and more thorough sugar extraction from the grain.

The false bottom, located at the heart of a lauter tun, is a crucial component that helps hold back solids while allowing liquids to pass through. 

Unlike traditional designs, today's false bottoms are made from wedge wire technology. These false bottoms have thin slits that serve as a filtration medium, effectively clarifying the cloudy mash as it flows out of the tub, leaving behind a clear liquid rich in sugars.

Wedge wire technology offers a remarkable advantage, providing a free-flow surface area of up to 12% of the tun's bottom. This increased surface area enhances the efficiency of sugar extraction from the grain, minimizing loss.

In many breweries, a support grid called a wedge wire serves as the foundation for the false bottom in the lauter tun. This support grid is anchored to a ledge located along the tank's inner diameter, providing stability and structural integrity. Depending on the tank's load and diameter, additional support beams may be required to reinforce the false bottom and ensure smooth operation.

With these innovative features, modern lauter tuns equipped with wedge wire false bottoms offer unparalleled performance, facilitating quick and complete sugar extraction from the grain. Adopting this advanced technology leads to increased efficiency and productivity, leading to the creation of exceptional brews that delight connoisseurs worldwide.
