Description

Technical Field

[0001] The invention relates to the technical field of winemaking equipment, in particular to a wine fermentation device and a fermentation process thereof. Background Art

[0002] Wine is the most widely consumed fruit wine, and is widely loved by people all over the world because of its diverse and unique taste. Wine not only has a popular flavor, but also has many health benefits such as regulating metabolism, promoting blood circulation, diuresis, and preventing aging. It is a very healthy drink.

[0003] Winemaking usually uses the method of fermentation with skins. During the fermentation process, carbon dioxide gas is produced, and a large amount of carbon dioxide gas pushes the grape skins near the liquid surface upward. The grape skins will float on the upper surface of the fermentation liquid to form a skin and dregs cap. In order to fully contact the grape skins with the fermentation liquid, the skin and dregs cap needs to be pressed back into the fermentation liquid, which is the "cap pressing" operation in winemaking. Spraying operation is also required to spray the lower fermentation liquid on the upper floating skin layer of the fermentation liquid surface to allow it to fully contact. Small-scale production generally uses manual cap pressing and manual spraying. Large-scale production generally uses spraying to absorb the fermentation liquid from the bottom of the fermentation tank and send it to the top of the tank through a water pump. In the early stage of fermentation, due to the small amount of juice, the juice suction pump often runs idle, and the spraying effect is not good. The manual cap pressing and spraying operations need to be performed regularly and uninterruptedly, and the spraying effect is not good. When the pump extracts the fermentation liquid, it is easy to suck it together with the peels and dregs, clogging the pump.

[0004] Based on this, the present invention designs a wine fermentation device and a fermentation process thereof to solve the above problems. Summary of the invention

[0039] During operation, the driving motor 10 drives the pressure cap spray structure to move downward, and the movement makes the pressure plate 3 farther and farther away from the upper wall of the structural shell 1. The fixed rack 11 and the gear shaft 26 on the pressure plate 3 move relative to each other. The gear shaft 26 starts to rotate under the power, and the No. 1 bevel gear shaft 24 and the No. 2 bevel gear shaft 25 meshing with the gear shaft 26 rotate. The No. 1 bevel gear shaft 24 meshes and drives the bevel gear screw 20 to rotate. The bevel gear screw 20 rotates to filter the fermentation liquid from the fermentation tank through the filter screen to remove the skin residue to prevent the bevel gear screw 20 from being blocked. The fermentation liquid will then enter the sealed liquid tank 21, and the screw shell 27 rises to the sealed liquid tank 21.

When it touches the skin residue, the motor built into the flip plate structure 30 is started to enable the flip plate 32 to flip. The flip plate 32 starts to flip and flips the skin residue floating on the fermentation liquid surface up and down, so that the upper and lower surfaces of the skin residue are fully in contact with the fermentation liquid. The pressing plate is pressed downward to make the skin residue completely immersed in the fermentation liquid, and the skin residue can be evenly and fully fermented.

[0045] During operation, the driving motor 10 above the mobile driving structure 4 is responsible for driving the pressing plate to move up and down. The fixed block 41 is fixedly connected to the pressing plate to reinforce the driving structure. The transmission structure 42 rotates under the drive of the driving motor 10, and the connecting slider slides up and down along the screw rod, driving the fixed block 41 and the pressing plate to move up and down, so that the pressing plate contacts the skin residue cap, completing the cap pressing operation during the fermentation process, so that the skin residue cap floating on the liquid surface can fully contact the fermentation liquid, and the fermentation liquid can be fermented more fully.
