The invention provides methods for the production of dough and bread products made at least in part of spent brewer's grain. The spent grain is removed from a brewing or distilling process, dried, frozen, and then further processed into a spent grain dough product. More specifically, the invention relates to the systems and methods for making frozen pizza dough balls composed at least in part of grain products that have been used in the process of brewing beer or distilling sprits such as whiskey.

A compact beer brewing system (1) has vessels (2, 3) configured to perform mashing, lautering and boiling brewing stages applicable in small scale craft brewing operations. The compact and cost efficient brewing system easily, precisely and repeatably controls and improves critical brew processes involved in brewing and serving by including bottom vessel (2) having an inner tun (28) configured to perform mashing and boiling stages, a top vessel (3) positioned above the bottom vessel (2) in fluid communication with the tun (28) and configured to perform lautering stage, and a pump (51) for moving fluid from the tun (28) to the top vessel (3). Preferably at least the bottom tun (28) and/or the top vessel (3) is/are substantially cylindrical, the diameter of the top vessel (3) is smaller than the diameter of the bottom tun (28) and the top vessel (3) is placed eccentrically over the bottom tun (28).

A method for combined production of beer and a non-fermented beverage from grain material makes use of a by-product in the beer production to produce the non-fermented beverage and thereby improves resource-efficiency. The method comprises processing the grain material into a mash; separating the mash into a fermentable wort and a retentate; processing a retentate material into a slurry, wherein the retentate material comprises at least a portion of the retentate; separating the slurry into a liquid component and a solid component; processing the liquid component into the non-fermented beverage; processing the fermentable wort into the beer; outputting the non-fermented beverage; and outputting the beer.

One aspect of the present invention relates to a method of producing a mash extract, said method comprising: a. mashing particulate, starch-containing and optionally malted raw materials with a recirculated aqueous stream; b. heating the mash and enzymatically hydrolysing the starch; c. transferring the heat-treated mash into a first separator for separation into mash extract and spent grain; d. transferring the spent grain into a first mixing vessel and mixing it with sparging water; e. transferring the mixture of spent grain and sparging water into a second separator to remove spent grain; f. recirculating an aqueous stream from the second separator to the mashing step,
wherein the gravity of the fermentable mash extract obtained from the first separator is maintained at above 15 P. The present method offers the advantage that it is highly efficient in terms of energy consumption and extraction yields. Furthermore, the present method achieves extremely high productivity in the operation of the brewhouse. The invention also provides an apparatus for carrying out the aforementioned method.

A device, system and method are for treating a suspension, containing plant constituents, in particular separating a liquid or a solid therefrom, in the field of production of food, pharmaceutical and luxury products, and to corresponding uses. The device for continuously or discontinuously treating a suspension, in particular for separating a liquid or liquid phase or a solid or a residual phase from the suspension includes: a receiving unit for receiving the suspension and at least one separating device having a surface having openings. The surface can be brought into contact with the suspension, if the suspension is present in the receiving unit for separation into the liquid phase and the solid phase. During the operation of the device, the surface is arranged such that it is moved or can be moved or can be rotated relative to the suspension, the solid phase and/or the receiving unit.

The present invention is directed to a beer having reduced quantities of AcHFA. It has been found that beer with reduced AcHFA quantities has improved foam stability. The invention provides beer with reduced AcHFA quantities, as well as methods for removing AcHFA from beer during or after fermentation, or for removing a precursor for AcHFA from wort.
