Abstract
This invention relates to a process for the continuous preparation of wort, including the continuous enzymatic conversion of malt in one rotating disc contactor and separation of spent grain from mash in a separation unit. Further, a process for the continuous preparation of wort, including 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.
Claims19
A process for the continuous preparation of wort, comprising providing a mixture to a rotating disc contractor, said rotating disc contactor comprising a column provided with a central agitator shaft having discs attached thereto, said mixture comprising water and one or more materials in a first group consisting of unmalted grain, malt, and an enzyme source other than malt, continuously gelatinizing and enzymatically liquefying said mixture in said rotating disc contactor to yield a first product, adding one or more materials in a second group consisting of malt and an enzyme source other than malt to said first product to yield a second product, enzymatically converting said second product, and separating spent grain from mash in a separation unit to provide wort, said materials in said first group and said materials in said second group being capable of passing through screens with a mesh size of from 5 .mu.m to 5 mm.
