Description

Technical Field

[0001] The utility model relates to the technical field of wine distiller, in particular to a wine distiller with annular heat exchange. Background Art

[0002] A distiller is a device that uses distillation to make or purify alcohol. Its working principle is to use the fact that the boiling point of alcohol is lower than that of water, to generate alcohol vapor by heating the fermented mash, and then to convert the vapor into liquid alcohol by cooling, thereby separating and purifying alcohol from other components.

[0003] A general wine distiller includes a heat source, a distillation pot, a pot cover and a condenser. The heat source heats the distillation pot. The water in the distillation pot absorbs the heat and generates steam. The high-temperature steam then heats the mash at the top of the distillation pot to generate wine vapor. Finally, it is condensed and separated through the condenser, so that the water and wine are separated and converted into liquids respectively.

[0004] In the prior art, a distillation device for liquid wine mash is disclosed, including a distillation pot body, a heat exchange component, a side insulation and heating interlayer and a bottom insulation and heating interlayer. The distillation pot body is indirectly heated by the side insulation and heating interlayer, the bottom insulation and heating interlayer and the heat exchange component, so that steam does not need to enter the distillation chamber. However, this structure can easily cause part of the wine mash to overheat, causing it to evaporate and produce a temperature that burns other materials, thereby affecting the taste of the wine. Moreover, its heat exchange effect is not general, and the temperature of the steam outlet is still high, affecting its thermal efficiency. Utility Model Content

[0018] 1. The wine distiller of the utility model adopts a chamber combustion structure, and the combustion chamber and the main flue are arranged in the distillation pot. The heat and high-temperature flue gas generated by the combustion of the fuel are directly transferred to the water in the distillation pot to form high-temperature steam. Then, the flue composed of the circular main flue and the labyrinth waste heat recovery flue can greatly prolong the residence time of the flue gas in the distillation pot to improve its thermal efficiency.

[0019] 2.

A water replenishment port is provided on the side of the distillation pot 10 for replenishing water therewith. A sewage outlet 11 is provided at the bottom of the distillation pot 10 for discharging sewage or fermented grains residue or other impurities at the bottom of the pot. In one embodiment, the combustion chamber 20 and the main flue 30 are both placed in the distillation pot 10, and the waste heat recovery flue 40 is located below the distillation pot 10. The main flue 30 is arranged roughly in a circular shape, and the waste heat recovery flue 40 is arranged roughly in a maze structure.
