SS 304 Wedge Wire False Bottom Screen For Brewery Lauter Tuns

In the brewing industry, especially during beer production, False bottom Johnson screen are used to filter and separate solid particles and suspended matter to improve the clarity and quality of beer.

The fermented liquid needs to go through a sieve filtration step to remove yeast, protein, malt residue and other solid particles, making the beer become clear and transparent.

At present, most of the filter grooves used in the brewery adopt cylindrical structure, including cylindrical groove, circular bottom plate, sieve and circular shaped wort confluence tube. Among them, the sieve is made of multiple fan blocks, and each fan block is milled by milling machine to make it the carrier of the filter layer.

But in the use of the process found that the above fan plate processing is very expensive material, and inconvenient to make, and the installation performance is poor.

At the same time, influenced by the fan structure, the surrounding sieve holes on the fan block cannot fully extend enough, resulting in the total area of the sieve hole is small.

That is to say, under the same conditions, in order to ensure the strength of the screen, and does not affect the filtration effect, developed a wedge screen (fine grille), composed of stainless steel wedge wire and support welding. The sieve has the advantages of smooth surface, high opening rate, high welding strength, uniform gap, high precision, easy backwashing, long service life, etc., which is a good filtration alternative product on the market at present.
