PURPOSE:To provide a fermenting tank capable controlling the temperature of a product by efficiently carrying out temperature control of brewed rice wine (sake), by dividing a jacket into three or more stages unlikely a conventional fermentation tank with a jacket, sending a heating medium such as warm water or a refrigerant such as cooling water to the each stage independently and to prepare a system for carrying out temperature control without reducing efficiency of cooling and heating by using this fermenting tank, applying a control rule such as fuzzy control to regulate fermentation and further sending the heating medium or the refrigerant to the independent jackets to mix media having large difference in temperature such as warm water or cooling water. CONSTITUTION:This fermenting tank has the following elements and a method for controlling temperature of a product uses this tank. The fermenting tank has a jacket divided into three or more stages into which a heating medium such as warm water or a refrigerant such as cooling water can be individually sent through the jacket, the heating medium is preferentially made to flow from the lower stage and the refrigerant preferentially from the upper stage and a natural convection is generated to fix the temperature of product. Each jacket is given a weight to be a system carrying out control of temperature of product such as fussy control. |
