Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to a fermentation device for preparing mandarin fish sauce. Background Art

[0002] Fish sauce, also known as fish soy sauce, mainly includes umami and salty flavors. When preparing mandarin fish sauce, the mandarin fish needs to be mixed with additives first, and after the mixing is completed, the mandarin fish and additives are put into a fermentation tank for fermentation;

[0003] Traditional fermentation tanks for preparing fish sauce are mostly tanks with an open top. During the preparation of fish sauce, personnel are required to manually stir the mandarin fish and additives in the fermentation tank regularly to improve the quality of the fish sauce. However, manual stirring by personnel is inefficient and the mixing effect is poor. For this reason, fermentation devices with mechanical stirring mechanisms have appeared on the market. When it is necessary to stir the mandarin fish and additives in the fermentation tank, the mandarin fish and additives are stirred by a machine to improve the stirring efficiency and mixing effect. In addition, in order to facilitate the preparation of refined liquid from the fermented fish sauce stock solution, the fermentation device is equipped with a mechanical stirring mechanism. A drain pipe is usually provided at the bottom of the device, a drain valve is provided on the drain pipe, and a filtering mechanism for blocking the drain pipe is provided in the fermentation device. When the fish sauce stock solution is discharged, the drain valve is pressed, and the mandarin fish stock solution in the fermentation device can be discharged through the drain pipe, and the suspended particles generated during the fermentation of the mandarin fish are filtered through the filtering mechanism, so as to facilitate the preparation of refined fish sauce liquid in the later stage. Although this prior art fish sauce fermentation device can improve the stirring efficiency and mixing effect, and is convenient for the preparation of refined fish sauce liquid in the later stage, it still has the following defects in actual use:

[0004] After the fish sauce fermentation is completed, the fermentation device needs to be cleaned to avoid the presence of fish sauce fermentation liquid and suspended particles in the fermentation device, thereby affecting the quality of the next fish sauce preparation. The fish sauce fermentation device of the prior art is provided with a drain pipe and a drain valve, and a stirring mechanism and a filtering mechanism are placed in the fermentation device, which makes it very inconvenient to clean the inside of the fish sauce fermentation device and the drain pipe and the drain valve, thereby making it inconvenient for the staff to clean the inside of the fermentation device, thereby reducing the cleaning efficiency.

[0005] Therefore, the present application proposes a fermenter for preparing mandarin fish sauce. Utility Model Content
