12. The fermenter according to claim 11, wherein the lid body is provided with a discharge structure, the discharge structure communicating the storage cavity with the outside, the discharge structure being capable of sealing the storage cavity or being in an unsealed state, the discharge structure being capable of discharging gas and/or liquid from the storage cavity when the storage cavity is in the unsealed state.
13. The fermentation tank of claim 12, wherein a liquid accumulation region is arranged at the bottom of the tank body, a filtering structure is arranged in the tank body, and the filtering structure is positioned above the liquid accumulation region; the fermented product is placed on a filtering structure and subjected to solid-liquid separation, and the separated liquid is gathered in the liquid accumulation area.
14. A fermenter according to claim 11, 12 or 13, wherein the inner wall of the body and/or the outer wall of the lid are provided with a sealing member at a position where they meet to provide a sealing relationship between the lid and the body.
15. A fermenter according to claim 12 or 13, wherein the drain structure is a drain structure and/or a vent structure; the cover body comprises a lining and an outer shell, and the lining and the outer shell are sealed with each other to form a storage cavity; the inner liner and the outer shell form an unsealed state, the opening of the liquid discharging structure and/or the opening of the air discharging structure, and gas and/or liquid in the storage cavity can be discharged.
16. A fermentation process in a fermenter, wherein the process is carried out using the fermenter according to any one of claims 11 to 15, comprising the steps of:
s01, placing the fermentation product on a filtering structure in the tank body;
s02, filtering liquid formed by the fermentation product into a liquid accumulation area through a filtering structure;
s03, enabling gas generated by the fermentation product to flow upwards and gather at the lower surface of the cover body, and enabling the gas to enter the storage cavity along the ventilation structure when the gas pressure generated by gas gathering is larger than the gas pressure in the storage cavity;
s04, when the temperature of the inner wall of the upper surface of the cover body is lower than the temperature of the gas in the storage cavity, condensing the gas in the storage cavity, forming a condensed liquid on the inner wall of the upper surface of the cover body, and dripping the condensed liquid into the storage cavity;
s05, when the gas in the storage cavity exceeds a threshold value, namely the space in the storage cavity is filled with the gas, the exhaust structure is opened, and the gas in the storage cavity is discharged;
