wedge wire False Bottom Lauter Tun filter for brewery

Product Details

Lautering is the process of separating sweet wort from the mashed grain.

The false bottom is standard in commercial breweries and very common in homebrew systems as well.

False bottoms are available from most homebrew supply stores. But you can get the false bottom which a lower price and higher quality from the export factory.

How is false bottom constructed?

The wedge wire screen lauter tun false bottom filter is installed in the Lauter tun to provide support for the grain bed during the mashing process and to retain the spent grain after runoff is complete. During the runoff, however, most of the separation of wort from grains occurs in the grain bed itself. Ideally, the grain bed floats several inches above the false bottom(30-40cm). In larger vessels, the false bottom is constructed as a series of interlocking plates that fit together to cover the entire area of the vessel bottom. Smaller vessels may have only two such plates. The design of the slots in the false bottom is important. They must be narrow enough to prevent large particles from passing through yet wide enough not to become blocked and prevent flow altogether. It is a good idea for the slots or holes to be wider on the under-side than on the top side to prevent particles that pass through the screen from plugging the gaps.

Our factory choose to construct the screens with V-shaped ( wedge wire) laid out in strips separated by an appropriate distance.

Each intersecting point in the V-shape section plane can avoid blockage, and make sure of the unimpeded water.
