Description

Technical Field

[0001] The utility model relates to the technical field of wine distiller, in particular to a wine distiller with roundabout 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 wine distilling device is disclosed, which consists of a pot body and a stove body. The stove body is mainly composed of a stove body interlayer, a grate, a water inlet pipe, and a combustion chamber. The pot body is mainly composed of a fire pipe, a water channel, and a flue. The flue is designed as a planar two-way rotary flue, which is provided with a preheated interlayer water channel around the stove body, and then the water channel and the flue are arranged at intervals in the pot body. The high-temperature flue gas generated by the combustion in the combustion chamber passes through the flue, transfers heat to the surrounding water, and is then discharged through the chimney. However, in the above structure, since the combustion chamber is placed at the center bottom of the pot body, the high-temperature flue gas transfers heat to the surroundings through the rotary flue. The smoke resistance of this structure is small and the smoke residence time is short, resulting in a higher temperature of the outlet smoke and a lower 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.

[0020] 3. In the wine distiller of the utility model, the high-temperature flue gas is centered on the combustion chamber, and gradually diffuses to both sides through the action of each rotating flue, and uses a circuitous heat exchange structure to extend the residence time of the flue gas in the pot body. Then, through the action of the waste heat recovery flue, the flue gas is made to flow toward the center as much as possible through the action of each smoke baffle plate, and to flow in a circuitous manner through the action of each smoke baffle circle, so as to cooperate with the action of the upper combustion chamber and the main flue, so that the water temperature in the middle of the bottom of the distillation pot is maintained at a higher temperature, which is convenient for heating the water in the middle to form high-temperature steam. In addition, the flow direction of the flue gas in the waste heat recovery flue forms a counterflow to the flow direction of the flue gas in the main flue, which is convenient for enhancing the heat transfer effect between the flue gas and water.
