Important Configuration of Lauter Tank


1. The lauter screen (also called false bottom, lauter filter etc.) is mounted 20mm away above the lauter tank bottom. The gap ratio is normally 10%-30%. Each gap looks like a upset ‘V’ shape, and the width is 0.7mm at lowest point, and 0.1 at top point.


2. For the industrial brewery, here are multi wort outlets at the bottom of the lauter tun. And all the branch wort outlets gather to a master wort outlet in the central place. We call it wort collecting rings. And the wort outlet tube should be a ‘cone’ or ‘arching’ shape.


This deign mostly avoid the over-pumping/vacuum condition and efficiently maintain a reasonable lauter speed. Now some brewmasters prefer to have it in their micro beer equipment, as this make the operation easier and decrease the observing intensity. Our suggestion is: you could consider to have it in your brewery that is over 1000L. And the wort collecting rings usually cooperates with a wort grant tank.


3. Rake: Rake is very important to speed up the lauter process and ensure the wort quality.

  • In most time, the grain bed is already very tight after the first lauter recirculating. So the rake is necessary to help to loosen the grain bed thus speed up the wort flow.

  • Besides, during sparging, rake can improve the contact of water and wort and add new wort flow routes, so the lauter process is quicker and the sparge is much more thoroughgoing.

Solutions to relieve a lauter blocking


While wort is filtered (lauter process), sometimes the filter speed is very slow that even stops, thus the lauter time is extended much, and the wort quality and normal brewing process is effected. The main reasons of this situation include: bad grain quality or non-good mashing result that caused poor sugar composition with a high viscosity, or the lauter operation error etc. So here are some urgent solutions:


1.Stop the lauter and start the lauter rake to loose the grain bed.

2.The bigger volume lauter tank is normally configured with anti-rinser rings. So we can spray into hot water (75-78℃) from the bottom to help with loosen. If the lauter speed is still not improved, then we can anti-rinse water and meanwhile start the rake for agitating 2-4 minutes. If necessary, increase the raking speed to damage the original grain bed, and then let the wort till for 5-10 minutes to form into a new grain bed, then restart the lauter. Besides. we should also pay attention to the lauter insulation. And the sparge water temperature can not be too low.

3.Slow down the pump/lauter speed to avoid ‘vacuum’ situation.
