The jacketed conical fermenter is defined as a standard in the whole micro brewery area. Conical bottom is convenient for recycling the yeast after finishing the fermenting. Glycol jacket is used for cooling down the temperature of fermentation vessel. The temperature of fermenting can be evenly decreased while glycol water is running inside the jackets wrapped around the fermenter. Usually there are 2 or 3 section jacket on the cylinder of fermentation tank and 1 section on bottom. The jacketed conical fermenter can combine the fermentation and maturation processes into one vessel mounted with a carbonation stone.
