Abstract: A transfer apparatus with which it is possible to transfer a mash in a storage tank to a mash tub without leaving any mash in the tank and with the addition of only a small-scale mechanism. In a viscous fluid transfer apparatus of related art made up of a storage tank (20) for storing a viscous fluid; a transfer pipe (31) for taking out the viscous fluid, extending from the bottom of the storage tank; and a pump mechanism (32) disposed in the transfer pipe (31), on the intake port (41) side of the pump mechanism the invention additionally provides a branch pipe (42) branching upward from the transfer pipe (31), an extension pipe (43), an evacuating mechanism (44) and an evacuation control part (46). For a while after the start of a transfer, the transfer is carried out with the pump mechanism (32) only.

Abstract: A soy sauce is produced by mixing a salt solution having a hard component concentration of not more than 20 ppm as calcium with a soy sauce koji, and subjecting the mixture to fermentation and ageing and then compressing it to obtain a crude soy sauce, and heat-treating the crude soy sauce in a plate-type exchanger, thereby the hard component decomposition on the plate surface being lowered and the frequency of washing the plate surface resulting in considerable decrease.
