摘要:
The present invention provides a continuous method of preparing a liquid extract of cereal grain by comminuting cereal grain at a rate of at least 100 kg of dry cereal grain per hour and extracting the comminuted cereal grain with a liquid, said method comprising: continuously combining cereal grain with a liquid; continuously disintegrating the grain particles contained within the liquid by colliding freely suspended grain particles with one or more rotating blades, thereby producing a milled suspension; continuously transferring at least a part of the milled suspension, optionally after further treatment, to a separation device for separation into spent grain and liquid extract; wherein the one or more rotating blades are rotating at a tip speed of at least 10 m/s; the total mechanical energy transferred into the milled suspension by the one or more rotating blades is in the range of 5-1000 kJ per kg of dry cereal grain; and the distance between a tip of said one or more rotating blades and the axis of rotation is in the range of 2-25 cm. The invention also provides a system for comprising a milling apparatus and a separation device suitable for use in the aforementioned method.The present method and system offer several advantages, including savings on capital expenditure and maintenance, short milling times and hygienic design.
摘要:
Stale flavor formation in beer is reduced by contracting malt, prior to extracting to produce wort, with a primary or secondary mono- or polyhydric alcohol or with acetic acid or with dimethylsulfoxide to reduce the amount of precursors of 2-trans-nonenal present in the malt.
摘要:
The invention relates to a process for whole-grain conditioning, in particular of native and malted brewing cereals. To improve the mashing process and to increase the number of brews and product quality, the brewing cereals are conditioned and subsequently fed to a hulling and/or mechanical comminution process.
摘要:
The conventional brewing process for producing a malt beverage which includes the preparation of a mash, the conversion of the mash to wort, the boiling of the wort, cooling of the wort and fermentation, is substantially abbreviated, e.g. by as much as 50% by subjecting malt flour to air classification to produce a fraction having a high starch content which is used in the mash, whereby the mash conversion and wort boiling steps can be combined in a one-kettle operation to yield a fermentable boiled wort. Moreover, the by-product of the air-classification is a high protein malt flour which can be used to make bread.
