Abstract: The present invention relates to a wort kettle for boiling wort for brewing, the wort kettle comprising a vapor escape pipe and a vapor compressor, wherein vapor can escape to the outside via the vapor escape pipe during heating of the wort kettle and can be diverted by means of a shut-off device via the vapor compressor during boiling. In accordance with the invention, the shut-off device is formed by a water tank which is arranged in the direction of flow of the vapor in the vapor escape pipe behind the branch towards the vapor compressor.

Abstract: The invention relates to a wort boiler apparatus comprising a wort boiler vessel and at least one separate heating circuit external of the boiler vessel and including a heat exchanger for heating or boiling the wort, the heat exchanger comprising an arrangement of heat exchanger pipes for passing the wort through the heat exchanger. The object of the invention is to provide a heat exchanger adapted to be adjusted to different evaporation values as required for making different types of beer. To attain this object, the invention provides that the arrangement of heat exchanger pipes includes pipe connections and valves in an arrangement permitting the wort to be passed through the heat exchanger along flowpaths of different lengths.

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.

Abstract: A wort cooking or boiling arrangement, which operates with vapor concentration, including a wort cauldron or kettle and with two separate heating circuits which are located externally of the wort cauldron and which are formed by heat exchangers. One of the heat exchangers (live steam heat exchanger) is supplied with live stem for the heating of the worts, and the other heat exchanger (vapor heat exchanger) is supplied with concentrated vapors for the subsequent cooking or boiling of the worts. The two heat exchangers are located in each other within a common external cooker.

Abstract: The invention relates to a method for macerating and wet-crushing brewing ingredients, wherein the brewing ingredients are continuously taken from a supply container. Subsequently substantially equal portions of the brewing ingredients are conveyed along a circular path, and an excess of macerating water is added thereto. The excessive macerating water is collected and discarded, whereupon the brewing ingredients are fed to a wet-crushing mill. A simplification of known methods, and of the structure of known apparatus for carrying out such method is achieved by the provision that the macerating process is carried out exclusively during transport of the brewing ingredients along the circular path, and that the macerated brewing ingredients are then immediately fed to the wet-crushing mill.

Abstract: The invention relates to a boiler for boiling a mash or wort, having an interior partition dividing the boiler into a heat exchanger section and a precipitation section. The boiler according to the invention is characterized in that the partition divides the boiler into an inner precipitation section and a surrounding heat exchanger section, i.e. in that the precipitation section and the heat exchanger section are disposed one within the other. This results in the particular advantage that the overall height of the boiler may be reduced. Since in addition the full height of the boiler is available for the accommodation of pipe conduits in the heat exchanger section, the flow resistance in the pipe conduits may be reduced. In summary, the boiler according to the invention is of simple construction to thereby facilitate the cleaning thereof.
