Abstract

A supplementary wort removal device in lauter tuns is provided, in order to avoid tight and solidly constructed discharge pipe assemblies with check valves for the wort, and the supplementary wort removal device preferably has a plurality of annularly segmented and vertically movable hollow members with screen walls, and the hollow members are open on the bottom. Preferably, the hollow members have a transverse section in the form of an inverted U or V. Before the pumping of the mash into the lauter tun, the hollow members are simply placed with their open bottoms on the screen and/or perforated floor of the lauter tun. The wort which is being discharged from the draff layer and flowing through the screen walls into the inside chambers of hollow members flows further through the open bottoms of hollow members directly through the screen and/or perforated floor of the lauter tun and into a collection chamber between the screen and/or perforated floor and the tun floor.
