一种葡萄酒发酵设备
By using a lifting piston structure to force the fruit skins in the wine fermentation equipment to sink, the problem of insufficient contact between the fruit skins and the liquid in traditional fermentation tanks is solved, resulting in a higher anthocyanin release rate and wine quality, while reducing mechanical energy consumption.

AI Technical Summary
In traditional fermentation tanks, grape skins float on the surface of the liquid due to their low density, resulting in insufficient contact between anthocyanins, tannins, and other substances and the liquid, which affects fermentation efficiency and quality. Existing technologies promote mixing by stirring, but this can easily lead to skin breakage, affecting the taste of the wine.
Design a wine fermentation device that uses a lifting piston structure to press down the plate, forcing the fruit skin floating on the liquid surface to sink, increasing the contact area between the fruit skin and the liquid, and ensuring flow through the liquid permeation holes to prevent the fruit skin from breaking. A gas generator is used to drive the plate to press down to reduce mechanical energy consumption.
It significantly increases the contact area between the fruit skin and the liquid, improves the release rate of anthocyanins, ensures the integrity of the fruit skin, enhances fermentation efficiency and wine quality, and reduces mechanical energy consumption.
