top in this region the strainer basket 5 a can be closed around the pressure worm 3 a for collecting the press water underneath the strainer basket 5 or underneath the strainer basket 5 a a drip channel 7 can be provided each having a slope the slope of the drip channel underneath the pressure worm 3 is for example 1 so that the remaining fluid can drain via the outlet 42 the drip channel 7 a can either be connected to the drip channel 7 or it can remove the remaining fluid separately as can be taken from fig1 as an alternative to a channel arranged underneath the strainer basket corresponding to the above embodiments see fig2 a closed housing can be arranged around the strainer basket 5 the pressure worm 3 is speed or frequency controlled so that the performance can be adapted to generate a pressing power for example a pressure worm can be used of which the diameter increases in the direction f or towards its end region such as a conical pressure worm as an alternative or in addition and as can be taken in particular from fig1 a resistance 41 here a press cone can be attached at the end of the pressure worm 3 3 a which determines the pressing power onto the spent grain the resistance can be pneumatically controlled so that the pressing power can be adjusted via the position of the resistance element here the cone 41 as well as depending on the speed of the pressure worm the further the resistance element closes the outlet region 43 and the higher the speed is the higher is the pressing power in the pressure worm 3 thus in the method according to the disclosure the spent.
