The German made Yeast Booster Pro from Quantor offers a labor saving, precise, repeatable method for rehydrating dry yeast. Designed to rehydrate up to 2,000 grams of yeast at a time (available Yeast Booster Max handles up to 10,000 grams) with built-in temperature control and automated pumping in of water and juice. The result is consistently healthy yeast, producing optimum flavors, with greatly reduced chances of stuck fermentation.
The Yeast-Booster is run by a processor. All the required parameters can be set in the menu: start temperature, target temperature, time, etc. From the menu change the language and adjust the display lighting contrast. In the start phase the water will be heated to 101.3°F/38.5°C. Upon reaching the target temperature the yeast is added to the mixture. During the first phase of the propagation, the yeast will be gently circulated through a membrane pump, which will break up lumps and add oxygen to the mixture. Fresh must from the target tank will be added to the mixture every 15 minutes to acclimate the yeast. At the end of the up-scaling process, the propagated yeast mixture will be pumped into the target tank. The Yeast-Booster can then start the rinsing and cleaning cycle. The cycle lasts 2-3 hours, allowing time for cells to become active and begin replication.
The Yeast Booster is equipped with robust motorized valves, a strong pump for faster emptying, and a perforated stainless screen at the bottom of the tank breaking-up remaining clumps of dry-yeast to reach a fine, homogenous mixture. The unit is jacketed for connection to water (or glycol) for cooling and also features a built-in electric heater for precise temperature control during rehydration. Tank, screen, control panel, and frame are made from stainless steel.
