after one fermentation stage is completed, the fermentation liquid in the fermentation outer cylinder 2 is discharged through the water outlet 22;
The rotary driving mechanism 6 drives each containing cage 5 and the filtering inner cylinder 4 to rotate in the fermentation inner cylinder 2, and the pressing driving mechanism 7 drives each containing cage 5 to shrink along the vertical direction, so that fermentation liquor in each containing cage 5 is fully discharged;
then, the clear water is injected into the fermentation outer cylinder 2 through the liquid pump 33, and the next fermentation stage is continued;
And after the last fermentation stage is completed, fully discharging the fermentation liquid in each containing cage 5, and starting the fermentation outer cylinder 2 to take out the fermented prefabricated vegetable raw materials.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
