Abstract:
1. A continuous method of preparing a liquid extract of cereal grain, comprising: (a) continuously combining cereal grain particles with a liquid; (b) continuously disintegrating the grain particles within the liquid by colliding freely suspended grain particles with one or more rotating blades, thereby producing a milled suspension; and (c) continuously transferring at least a part of the milled suspension to a separation device for separation of the suspension into spent grain and liquid extract; wherein the one or more rotating blades rotate at a tip speed of at least 10 m/s; wherein 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 wherein the distance between a tip of the one or more rotating blades and the axis of rotation is in the range of 2-25 cm.
