Important Configuration For Lauter Tun

The rath strainer (also known as false bottom, rath strainer, etc.) is installed 20 mm above the bottom of the rath canister. The slit rate is usually 10-30%. Each slit looks like an uneasy “V” shape with a width of 0.7 mm at the lowest point and 0.1 mm at the highest point.
For industrial breweries, here there are multiple wort outlets at the bottom of the fermenter. All branch wort outlets are concentrated to the main wort outlet in the center. We call this the wort collection ring. The wort outlet tube should be a “tapered” or “arched” shape.
This design is primarily intended to avoid an over pumped/vacuum condition and to effectively maintain a reasonable sintering rate. Some brewers now prefer to use this design in their microbrewing equipment because it makes handling easier and reduces the intensity of observation. Our advice: you might consider installing it in your 1000+ liter brewery. The wort collection ring is usually used in conjunction with a wort granting tank.
Rake.
Rakes are important to speed up the boiling process and ensure wort quality.
a. In most cases, the grain bed is already very tight after the first cycle.
Therefore, a rake is necessary to help loosen the grain bed and thus speed up the flow of wort.
b. In addition, the rake improves the contact between water and wort during the refilling process and adds new wort flow routes, so the rath process is faster and the refilling is more thorough.
