Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of evaporation stills, especially a kind of evaporation still for separating ethanol in fruit wine from fruit wine stock solution. BACKGROUND

[0002] Non-alcoholic fruit wine retains the original nutrient ingredients, color, aroma, taste and flavor of ordinary fruit wine, and does not contain alcohol, which is a new type of non-alcoholic beverage. In the production process of non-alcoholic fruit wine, an evaporator is used to separate ethanol from fruit wine stock solution, thereby obtaining an alcohol-free beverage. CN 118995358 A discloses a production method of non-alcoholic fruit wine, which realizes the production of non-alcoholic fruit wine through an evaporation device, specifically comprising the following steps: step one: extend the telescopic rod to block the hollow cone from the evaporator, then extract the air in the evaporator and the secondary evaporation tank through the steam outlet. The present application sets a conical ring, so that the fruit wine will contact the inner wall of the evaporator under the shielding effect of the conical ring during the process of entering the evaporator. During the process of falling along the inner wall of the evaporator, the fruit wine can fully contact the inner wall of the evaporator, thereby enabling the fruit wine to directly receive the heat from the inner wall of the evaporator, and rapidly warming up the fruit wine to ensure the efficiency of heat conduction, and thus effectively volatilizing the alcohol. The patent application also discloses an evaporator for producing non-alcoholic fruit wine. However, the inside of the evaporator is a hollow cylinder, and multiple arc-shaped scrapers are arranged in the cylinder. The fruit wine is distributed to the inner wall of the evaporator by rotating the arc-shaped scrapers, which makes the fruit wine not flow along the specified route in the evaporator. In order to completely separate the alcohol in the fruit wine, the evaporator can only adopt an intermittent batch operation mode, i.e. allowing the fruit wine to stay in the evaporator for heating and alcohol separation, and then discharging the remaining liquid material from the evaporator. It cannot realize continuous evaporation operation of continuous input of alcohol-containing liquid and continuous output of alcohol and non-alcoholic liquid. SUMMARY
