An on-line sensoring system for ethanol and specific gravity in sake-mash using liquefied rice as a raw material (Kakemai) was developed. The specific gravity of sake-mash was measured with a pipe-line automatic density meter (Type 7830 : Solatron Co., Ltd.) by circulating sake-mash with a pump. The specific gravity in the filtrate was estimated from this sake-mash density. Alcohol concentration was estimated from the specific gravity in the filtrate on mass balance indirectly. The respective estimated data agreed well with the results of manual analysis during the whole fermentation period. Simultaneously, this sensoring system enabled sake-mash to be mixed, so taht the sake-mash temperature was controlled exactly with a PID controller.
