This process is continued until the yeast achieves the capacity of these 40,000 gallon fermenting tanks. The yeast is then harvested. The harvesting is nothing more than concentrating the yeast cells by passing the fermented liquid through large centrifugal pumps called separators. This process is similar to spinning clothes dry in a washing machine. The result is off-white liquid called cream yeast.
Further processing is dependent on the type of yeast desired.
In all the yeast processes, utmost care is taken to produce a product of the highest possible quality and purity. Samples are routinely checked by the laboratory and frequent cleaning and sterilization of the equipment are conducted to assure the proper standards are met. In one cup, add 1 teaspoon granulated sugar. Set timer for 10 minutes. What other examples can you think of where sugar is important to the growth of yeast.
