Title:
PRODUCTION OF EDIBLE VINEGAR
Document Type and Number:
Japanese Patent JP3493036
Kind Code:
B2
Abstract:
PURPOSE: To control the fermentation of edible vinegar without timelag by deaerating an acetic acid fermentation liquid sampled at preset time interval, determining the acetic acid concentration and alcohol concentration with densitometers and controlling the adding rate and quantity of acetic acid.
CONSTITUTION: An acetic acid fermentation liquid is sampled from a fermentation tank A with a fixed delivery pump at preset time intervals and introduced into an ultrasonic apparatus D for the determination of the concentrations of multiple components to determine the acetic acid concentration and the alcohol concentration of the sampled liquid. The production rate of acetic acid and the consumption rate of alcohol are calculated from the acetic acid concentration and the alcohol concentration by a CPU to obtain the adding rate and quantity of alcohol necessary for getting the target concentrations. The preset values of an alcohol addition apparatus is automatically changed to the calculated values to control the acetic acid fermentation.
