In a method of operating a centrifugal separator for separating at least one liquid phase and a sludge phase from a liquid feed mixture, the centrifugal separator includes a frame, a drive member and a centrifuge bowl. The drive member is configured to rotate the centrifuge bowl in relation to the frame around an axis of rotation. The centrifuge bowl encloses a separation space and a sludge space. The separation space includes a stack of separation discs arranged coaxially around the axis of rotation and the sludge space is arranged radially outside the stack of separation discs. The centrifuge bowl includes an inlet for receiving the liquid feed mixture, at least one liquid outlet for a separated liquid phase, and sludge outlets for a separated sludge phase arranged at the periphery of the centrifuge bowl. The method comprises a step a) of supplying a liquid feed mixture to be separated to the inlet of the centrifuge bowl, a step b) of determining a particle flow rate of the liquid feed mixture being supplied in step a), a step c) of determining a volume filled with particles within the centrifuge bowl based on the measurements of step b), and a step d) of discharging a sludge phase including the particles via the sludge outlets based on the determination of step b), wherein the discharge is of a specific volume or at a specific time point.

This invention relates to a method for recovering beer during a beer brewing process. In the method, yeast entrained in beer 36 is recovered from a fermentation step 32. The yeast is separated from the beer to provide recovered beer 42. The recovered beer 42 is passed through an ultraviolet (UV) photo-sterilization unit 46, to provide sterilized recovered beer 48 which is recycled to the fermentation step 32. The invention uses ultraviolet light to achieve a microbially safe beer recovered from surplus yeast, and the recovered beer is recycled back to the brewing process, thereby saving financially as well as water loss.

The present disclosure provides methods of preparing a high color concentrate (HCC) wine. Aspects of the methods may include obtaining a grape fluid composition from one or more grapes, contacting the grape fluid composition with a reagent to modify the pH, adding an amount of distilled alcohol to the grape fluid composition to produce a fortified wine composition, and concentrating the fortified wine composition to produce an HCC wine. Aspects of the methods may further include obtaining a must from one or more grapes, fermenting the must to produce a grape fluid composition having a percent alcohol content, contacting the grape fluid composition with a reagent to modify the pH, and concentrating the grape fluid composition to produce an HCC wine. Also provided is a composition including the HCC wine produced according to the subject methods.

A beverage gasification system for concurrently extracting solid particulates from a solution of a liquid and a gas and increasing absorption of the gas into the liquid, in which a particle separator is located downstream of a gas supply assembly. A method of forming a clarified gasified beverage is also disclosed, in which gas is injected into the liquid at a location upstream of the point at which solids are removed from the liquid.
