METHOD FOR MANUFACTURING FERMENTATION PRODUCTS WITH A SENSOR DEVICE

The present invention is a manufacturing method for producing fermentation products using a fermentation vessel, including steps of: preparing a fermentation vessel and a sensor, introducing liquid into the fermentation vessel, and operating the fermentation vessel in which properties of liquid in the fermentation vessel are measured to adjust operating conditions; wherein the sensor device has a sensor for measuring liquid properties and a sensor cover body; a bottom permeable portion for passing liquid and crystals in the liquid is disposed on the bottom surface of the cover body, and a top permeable portion for passing liquid and crystals in the liquid is disposed on the top surface of the cover body; micropores are respectively formed in the bottom permeable portion and the top permeable portion; and micropores disposed in the top permeable portion are the same or larger than micropores disposed in the top permeable portion.
