Description

Technical Field

[0001] This utility model relates to the technical field of fruit wine processing equipment, and in particular to a fermentation tank for papaya fruit wine. Background Technology

[0002] The fruit of the common papaya can be used not only as a fruit and vegetable, but also for various medicinal purposes. Papaya contains abundant papain and papain protease, which can help lower blood pressure and fight tumors. Unripe papayas are often harvested to make wine for consumption.

[0003] In the prior art, patent application number 201820151102.7 discloses a fermentation tank for papaya winemaking, including a tank body, a cutting blade, a main water supply pipe, and a linkage shaft. From left to right, an inlet, a handle, and a vent pipe are sequentially installed on the top of the tank body, with a material conveying pipe located below the inlet. A fixed shaft is installed below the handle, and the cutting blade is located outside the fixed shaft. The main water supply pipe is located inside the tank body, and a secondary water supply pipe is connected to the left side of the main water supply pipe. The linkage shaft passes through the center of an isolation filter, and a motor is installed below the linkage shaft. A stirring shaft is fixed to the outside of the linkage shaft and is located above the isolation filter. In this papaya winemaking fermentation tank, the cutting blade can cut the papaya, reducing its volume and thus improving the efficiency of subsequent fermentation. The isolation filter installed inside the tank body isolates the fermenting material, allowing the fermentation liquid to flow out directly and preventing residue from mixing with the fermentation liquid.

[0004] The current method for fermenting papaya is to place the papaya directly into a fermentation tank. However, the pectin and cellulose in papaya are not easily hydrolyzed, which affects the fermentation efficiency of papaya wine. Utility Model Content
