A method of controlling undesirable microorganism concentration in an aqueous fluid solution employed in a fermentation process is disclosed. An example of the method includes introducing a fermentable carbohydrate to the aqueous fluid solution. The example method also includes introducing at least one desirable microorganism that is capable of fermenting carbohydrate to the aqueous fluid solution. The example method also includes introducing at least one lauric arginate (LAE) compound as a preservative into the aqueous fluid solution at a rate of between about two (2) pounds and about fifty (50) pounds LAE per ton of distillers grain. The example method also includes adding a surfactant (e.g., Polysorbate 80) to the LAE to improve solubility and efficacy of LAE during the fermentation process.

Device (V) for obtaining a wort (WO) from a mash (MA) in the beer brewing or beverage industry, at least comprising a receiving unit (AG) for receiving the mash (MA); at least one separating device (T; T1, T2) each having a surface (FA; FA1, FA2); wherein the surface (FA) has a multiplicity of openings (OP); wherein the device (V) is preferably suitable for separating the mash (MA) into the wort (WO) and a residual mash (RM) by means of the surface (FA) of the separating device (T); wherein the surface (FA; FA1, FA2) or a part thereof can be brought into contact with the mash (MA), if the mash (MA) is present in the receiving unit (AG) for separation into the wort (WO) and the residual mash (RM); and wherein, during the operation of the device (V), the surface (FA) is arranged such that it is moved or can be moved or can be rotated relative to the mash (MA), the residual mash (RM) and/or the receiving unit (AG).

A process of making a fuel product from spent grain from a beer brewing process. In the brewing process, the grain is pulverized to a particle size whose mean particle size is approximately 0.25 mm to 0.6 mm with less than 1% greater than 2 mm. After the brewing sugars are extracted from the grain, the spent grain is pressed against a filter to reduce moisture below sixty-five percent (65%), and then the grain is dried to further reduce its moisture to less than ten percent (10%). The dried spent grain, after the aforementioned processing, is fed into a combustion chamber for a steam boiler that is used for beer brewing, and the spent grain is separated during combustion by agitation such as spraying of the grain in the combustion chamber.

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.
