Abstract
A method of propagating, concentrating and delivering yeast is disclosed. The method comprises the steps of producing and inoculating a bag, propagating yeast within the bag, and concentrating the yeast in a section of the bag that is the removed from the remainder of the bag while not exposing any portion of the yeast therein to an external environment. In order to remove the bag, which contains the most concentrated slurry of yeast, a smaller bag is heat-sealed off of the larger bag, thereby creating a separate bag for the living sediment, which is still the bag in which the sediment was propagated. In a preferred embodiment, the method is specific to the alcoholic beverage industry. The method is also applicable to other industries that grow and transport yeast, bacteria, molds and other microorganisms.
Claims12
A yeast preparation method comprising the steps of:
- a. providing at least one bag comprising at least one pathway for the introduction of air and for exhausting gases;
- b. installing said at least one bag into a skid unit with a means for separating and sealing the at least one bag;
- c. propagating yeast within said at least one bag;
- d. concentrating said yeast in a small section of said at least one bag;
- and
- e. separating and sealing, using the means of step b, said small section of said at least one bag from said at least one bag, while not exposing the yeast in said small section of said at least one sealed bag to contamination.
