Abstract: This invention relates to a process for the continuous boiling of wort, comprising feeding the unboiled wort to a wort heater, wherein it is heated to a temperature between 75 and 125.degree. C., introducing the heated wort in a plug flow reactor, preferably a rotating disc holding column, followed by treating the wort obtained from said reactor in countercurrent with steam in a stripping column.

Abstract: This invention relates to a process for the continuous preparation of wort, comprising the continuous enzymatic conversion of malt in at least one rotating disc contactor and separation of spent grain from mash in a separation unit, as well as a process for the continuous preparation of wort, comprising the continuous gelatinization and enzymatic liquefaction of a mixture based on unmalted grain, malt and/or an enzyme source and water in a rotating disc contactor, addition of malt and/or enzyme source to the product obtained, enzymatic conversion of the product obtained and separation of the spent grain from the mash in a separation unit.

Abstract: This invention relates to a process for the preparation of wort starting from mash, comprising the separation of spent grain from the mash to form a clear wort in at least one membrane filtration unit having a pore size of the filter not exceeding 2.0 .mu.m, if desired addition of hops to the wort and boiling of the wort.

Abstract: A method of separating trub from hot wort, in which unpurified hot wort is supplied to a settling device and after the settling process purified wort is withdrawn at a level above the bottom of the settling device, and trub is withdrawn at a level at or near the bottom of the settling device. According to the invention, a gravity-induced circulation is created in the settling device by withdrawing heat from one part of the surface of the wort liquid and screening off the other part of the surface against heat loss. A column of liquid topped by said one part is kept separate from a column of liquid topped by the other part throughout its entire height, except for a narrow upper gap and a bottom gap.
