Abstract
A whirlpool for discharging hot dregs from the wort in a beer brewing process. The whirlpool includes a circular receptacle having a diameter which is approximately 2.0 to 3.5 times as large as its liquid level and a base onto the central area of which nozzles are directed for leading the dregs deposited in the area off to the outer marginal area of the base. The whirlpool includes at least two nozzles (12: 36, 37) that are arranged above the base (3;25) such that they are adapted to be rotated about the central longitudinal axis (2; 23) of the receptacle. The plane including the central longitudinal axis (21) of the nozzle may extend at an oblique angle to a perpendicular to the base. In one embodiment, a steam supply tube (1) is secured to the base of the receptacle, the tube being coaxial with the central longitudinal axis of the receptacle. An annular passage (9) is formed on the outer side of the tube, the annular passage communicating with a source of fluid and the nozzles. In another embodiment, a stationary liquid supply tube (24) and a guide mandrel (29) are secured to the base of the receptacle, both being coaxial with the central longitudinal axis of the receptacle. A rotatable tube portion (26) provided with nozzles is mounted coaxially on the liquid supply tube. The liquid supply tube is closed by means of a cap (28) and the mandrel extends through and engages the cap. The nozzles may be secured in position at different height levels of the rotatable tube portion.
