Title: Postopek magnetnega izločanja kvasne biomase iz penečega vina [SL], Process of Magnetic Precipitation of Yeast Biomass from Sparkling Wine [EN]
Description: The subject of invention is a process of magnetic precipitation of yeast biomass from sparkling wine using magnetic particles, to replace time consuming and expensive classical process. The classical process is based on a manual turningand lifting of bottles in vertical position with neck down. Using classical procedure takes about 60 days of manual labor for spent yeast biomass to accumulate in the bottle neck as sediment. After the sediment is in the bottle neck, it is removed by freezing and removing of the neck. By using magnetic particles that are absorbed by the yeast required in secondary fermentation, or their absorption on the spent yeast biomass after the secondary fermentation, the response of biomass to a magnetic field is achieved, and can thus be magnetically precipitated. Biomass, which has absorbed magnetic particles on the yeast surface, can be in approx. 15 minutes with the help of an external magnetic field settled in the bottle neck while further proceedings remains the same as in the classical champagne process, that is, by freezing the sediment and its removal.
