2results about How to "Normal fermentation" patented technology

This utility model belongs to the technical field of fermentation culture devices, and particularly relates to a fermentation culture device for processing N-acetylneuraminic acid. It includes a shell, and further includes: a power chamber, which is located within the shell. Four first gears are rotatably mounted within the power chamber, and rotating columns are fixedly mounted at the bottom of each of the four first gears. Two storage tanks are located within the shell. The lower ends of the four rotating columns penetrate the power chamber and extend into the two storage tanks respectively. Several stirring blades are fixedly mounted on each of the four rotating columns, which are rotatably connected to the power chamber and the two storage tanks respectively. A drive assembly is located within the shell and is used to drive the four first gears to rotate. Four fixing plates are fixedly mounted in the two storage tanks respectively, and sliding plates are slidably mounted within each of the four fixing plates. This device can ferment four types of N-acetylneuraminic acid, and the storage space can be adjusted according to requirements. It is simple and convenient to operate.

This invention discloses a method for identifying and warning of abnormal temperatures during the fermentation process of baijiu (Chinese liquor). The method includes: collecting temperature data from several temperature measurement points at several time points during the fermentation process in a target fermentation pit; fitting the temperature data from the same temperature measurement point during a single fermentation process into a temperature curve; scoring the temperature curve based on the final fermentation result; selecting temperature curves with scores higher than a threshold; fitting the selected temperature curves from the same temperature measurement point to obtain the temperature range for each time point, and merging all temperature ranges into a standard temperature band for the measurement point; using the standard curve to identify the temperature data collected during the fermentation process in the target fermentation pit, and issuing an alarm if the temperature data is abnormal. This invention combines historical data from the fermentation pit temperature measurement points to obtain the optimal temperature range for that time point, providing a reference for the subsequent fermentation process, and enabling timely and appropriate abnormal temperature identification and warning, effectively ensuring the normal fermentation of baijiu.
