Title:
METHOD OF PREPARING A LIQUID EXTRACT OF CEREAL GRAIN AND APPARATUS SUITABLE FOR USE IN SUCH METHOD
Document Type and Number:
WIPO Patent Application WO/2010/090522
Kind Code:
A3
Abstract:
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 5 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;10 -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 15 rotating blades is in the range of 5-1000 k J 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.20 The present method and system offer several advantages, including savings on capital expenditure and maintenance, short milling times and hygienic design.
