Fermentation cylinder special for brewing litchi wine

Abstract

The invention discloses a fermentation cylinder special for brewing lychee wine, comprising a cylinder body, a feeding port and a discharging port which are arranged on the cylinder body, and a cooling belt which is arranged on the outside surface of the cylinder body, wherein, the design of the wall of the cylinder body is of a three-layer structure which has an inner layer and an outer layer made of metal or alloy materials and an intermediate layer made of 18 to 23mm of polyurethane materials. The fermentation cylinder, having insulation function, can control the temperature of fermentation so that lychee can be fermented at a best temperature (between 12 and 15 DEG C), thereby maintaining the fruit flavor of the lychee wine. Meanwhile, the fermentation cylinder also can be used for storing the lychee wine at a lower temperature, and creatively realizes the combination of fermentation cylinder and wine storage cylinder.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a fermenter specially used for brewing lychee wine. Background technique [0002] As we all know, the most important fruit wine variety in the world is wine. After more than 100 years of research and industrial production, its related technical theory and equipment have reached a fairly modern level. Especially in western countries, it occupies a considerable share of life and the entire industry. Other fruit wines such as cider, perry, etc. account for a very small share. Fruits such as grapes, apples and pears are all temperate fruits. The fruit wine produced by tropical and subtropical fruits in the world has not yet formed a large-scale production, and its related research and equipment are still in the initial stage of development. Litchi, a subtropical fruit, is the original and main fruit of my country. Its unique aroma and taste fascinate the world. There are a certain ...

AI Technical Summary

Problems solved by technology

However, the existing fermentation tanks are only suitable for the fermentation of temperate fruits. If wine fermentation tanks are used to ferment lychee wine, the process temperature will be uncontrollable, the cooling consumption will be too large, and there will be temperature stratification in the tank, causing the fermentation liquid to flow. Slow or stop, or even freeze in the cooling zone, the temperature of the top and bottom of the tank is out of control and too high, causing bacterial contamination
