PROBLEM TO BE SOLVED: To provide a fermentation apparatus that efficiently heats a liquid containing fermentation microorganisms.SOLUTION: In a fermentation apparatus 50, a vessel 2 for storing a liquid containing fermentation microorganisms is made of woods 2b. In a fermentation apparatus 50, the liquid containing fermentation microorganisms to be converted into soy sauce having a salinity of 12% or more is stored in the vessel 2 constituted by combining the woods 2b having a board thickness of 65-85 mm. The fermentation apparatus 50 is provided with an insulating part 8 arranged between the vessel 2 and a base 4, on which the vessel 2 is mounted, and preventing electric current flowing in the liquid from flowing from the vessel 2 to the base 4. The fermentation apparatus 50 includes electrodes therein, and an electric current is applied from the electrodes to the liquid containing the fermentation microorganisms to generate heat, Joule heat, by the electric resistance of the liquid. In a fermentation method, proper temperature control of the fermentation apparatus 50 to promote the growth and metabolism of the fermentation microorganisms is performed by heating the liquid containing the fermentation microorganisms using the Joule heat.SELECTED DRAWING: Figure 1 |
