Industrial Fermentation

industrial fermentation, high alcohol tolerance, moonshine still and distillery instruments
Distillation of industrial alcohol, which is normally not used for consumption, can be made in a two-step process. First, start an aereated fermentation and propagate up the yeast to 350,000,000 cells per ml. Then transfer this mash to a much larger batch of mash, where it is used as yeast. This gives a savings in yeast cost.

Temperature Tolerant Turbo yeast is excellent for this application, and provides the following benefits:

Ferments sugar, corn, molasses, barley, wheat, and similar

High osmo tolerance, stands 28% sugar or equivalent

High temperature tolerance, 39C for 14%

High alcohol tolerance, easily ferments to 16%

Faster fermentation, increased production

Purer fermentation, 1% less fusel replaced by pure alcohol

No wild yeast, no bacteria: always a good result

More information

The fermentation in the first tank is always made using 3.6 Kg Temperature Tolerant Turbo Yeast per 1000 liter mash. Then it is tranferred to the next fementer with much times more of the same mash.

The mash in Fermenter 2 is fed with nutrients as usual, and pH is regulated as usual.

The strain of yeast used is cultured especially for distillation application and not a bakers yeast. Furthermore, the strain is grown under sterile conditions to ensure absence of bacteria, which could otherwise influence quality of alcohol produced and the percentage yield from sugar. Pure, bacteria free yeast also keeps down the volatile production.

The difference between the two will increase as the volume you are fermenting increases. High temperatures will kill yeast. Where there is no alcohol, yeast dies at 42°C, but as the alcohol increases this "killing temperature" decreases. At 14% alcohol, the killing temperature for Temperature Tolerant Turbo drops to 36°C and at 20% alcohol with High Alcohol Turbo, down to 24°C.
