Part of the raw wine flows into the right distillation kettle and the left distillation kettle through the perfusion pipeline. Control the steam generator to generate steam to heat the right distillation kettle and the left distillation kettle through the fifth three-way valve, so that the raw wine in the right distillation kettle and the left distillation kettle is distilled into wine vapor.

[0025] S2. Control the fifth three-way valve to stop delivering steam to the left distillation kettle, so that the left distillation kettle stops heating while the right distillation kettle continues to heat. Control the wine vapor in the right distillation kettle to be transported into the left distillation kettle through the first series kettle pipeline, use the heat of the wine vapor to heat the left distillation kettle, and make the wine vapor in the right distillation kettle and the left distillation kettle converge and be transported into the second connection pipeline through the sixth connection pipeline and the sixth stop valve.

[0026] After the raw wine in the right distillation kettle is distilled, inject raw wine into the preheating kettle, the right distillation kettle and the left distillation kettle again, and control the right distillation kettle to stop heating while the left distillation kettle continues to heat, so that the wine vapor in the left distillation kettle is transported into the right distillation kettle through the second series kettle pipeline, and make the wine vapor in the right distillation kettle and the left distillation kettle converge and be transported into the second connection pipeline through the fifth connection pipeline and the fourth stop valve.

[0027] S3. The wine vapor in the second connection pipeline enters the heat medium pipeline. The raw wine in the preheating chamber exchanges heat with the wine vapor in the heat medium pipeline to preheat the raw wine in the preheating chamber and pre-cool the wine vapor in the heat medium pipeline. Then the wine vapor in the heat medium pipeline enters the refrigerant pipeline for condensation and the wine is discharged through the liquid outlet pipeline.

[0029] 1. The distillation equipment and distillation method for whisky brewing adopt the combination of a double distillation kettle and a preheating kettle. The two distillation kettles alternately distill and send the wine vapor into the preheating kettle to exchange heat with the raw wine in the preheating kettle, use the temperature of the raw wine in the preheating kettle for condensation, and at the same time use the raw wine to preheat the raw wine in the preheating kettle, which can directly produce wine in one distillation, improve the energy utilization efficiency, and increase the wine yield.

[0030] 2. The distillation equipment and distillation method for whisky brewing can make the heat of the residual liquid in the previous distillation kettle enter the next distillation kettle for full utilization when the two distillation kettles alternately distill. Further avoid heat loss and improve energy utilization efficiency.

[0031] 3. For the distillation equipment and distillation method for whisky brewing, the wine vapor does not directly enter the refrigerant pipeline after passing through the spiral heat medium pipeline only once. Instead, after the wine vapor accumulates to a certain air pressure value in the heat medium pipeline, the circulation mechanism is triggered, causing the wine vapor to continuously circulate in the heat medium pipeline and conduct heat exchange with the raw wine outside the pipeline. It is not until its temperature reaches the rated temperature that the temperature control valve is triggered to inject the wine vapor into the refrigerant pipeline. After the wine vapor is consumed to a certain extent in the heat medium pipeline, the gas injection channel is automatically opened to supplement gas into the heat medium pipeline.

The refrigerant pipe 940 is communicated with the heat medium pipe 230;

[0054] A steam mechanism 1200 is further arranged on the base 100. The steam mechanism 1200 includes a steam generator 1210. An eighth connecting pipe 1220 is arranged on the steam generator 1210. The steam generator 1210 is communicated with the right distillation kettle 300 and the left distillation kettle 400 through the eighth connecting pipe 1220.

[0055] In this embodiment: A liquid level gauge can be installed on the preheating kettle 200 to observe the change of the internal liquid level.

[0056] The right distillation kettle 300 is used for distilling the original liquor. An additional cavity or pipeline for storing substances other than the original liquor can be arranged in the right distillation kettle 300 to be connected to the eighth connecting pipe 1220. The steam generator 1210 generates water vapor, and the water vapor enters the right distillation kettle 300 through the eighth connecting pipe 1220.

[0057] The original liquor in the right distillation kettle 300 is heated by steam. The reflux cone 320 and the gooseneck pipe 330 are used to improve the distillation effect, so that the purity of the steam coming out of the gooseneck pipe 330 is improved. The exhaust pipe 340 and the sewage pipe 350 are used for exhausting and discharging sewage during and after the distillation process. The installation angle of the gooseneck pipe 330 can be switched among right angles, acute angles, and obtuse angles. Defoaming devices such as toothed, spiral, and stirring blades can also be installed in the right distillation kettle 300 to assist in distillation. A condensing water circulation device can also be added between the right distillation kettle 300 and the steam generator 1210 and the evaporator. Part of the steam and condensed water after the distillation and cooling of the hot steam can be recovered, and its heat can be regularly transmitted back to the steam generator 1210 to achieve heat recovery. Moreover, the steam condensed water is pure water, and the recovery of the condensed water can increase the service life of the steam generator 1210 and reduce scale formation.

[0058] The right rectifying column 500 can be a plate column or a packed column, which can improve the purity of the steam flowing out of the right rectifying column 500. The right flavoring column 700 is used to put in flavoring substances such as petals to enrich the taste of whisky.

[0059] First, the original liquor can be injected into the preheating chamber 220 through the original liquor pipe 240 by a liquid pump, and then part of the original liquor is diverted through the perfusion pipe 1010 into the right distillation kettle 300 and the left distillation kettle 400. The steam generator 1210 generates steam to heat the right distillation kettle 300 and the left distillation kettle 400, so that the original liquor in both is distilled.

[0060] After distilling for a certain period of time, the fifth three-way valve 1230 is controlled to stop delivering steam to the left distillation kettle 400, so that the left distillation kettle 400 stops heating, and the right distillation kettle 300 is heated intensively. At this time, the first three-way valve 1030 is controlled to make the steam in the right distillation kettle 300 enter the first series kettle pipe 1020 through the gooseneck pipe 330 and the first three-way valve 1030, and then enter the left distillation kettle 400. After the two parts of steam converge, the second three-way valve 1050 is controlled to make the steam enter the left rectifying column 600 through the fourth connecting pipe 1070 for rectification and preliminary condensation. After passing through the fourth three-way valve 1160 and the sixth connecting pipe 1150 and completing flavoring in the left flavoring column 800, it enters the gas transmission mechanism 260 through the fifth stop valve 1170 and the sixth stop valve 1180, and then enters the heat medium pipe 230 through the gas transmission mechanism 260.

[0061] The wine vapor entering the heat medium pipeline 230 exchanges heat with the cold raw wine in the preheating chamber 220, preheating the raw wine and precooling the wine vapor. Then the wine vapor in the heat medium pipeline 230 enters the refrigerant pipeline 940. Condensed water such as tap water can be poured into the cooling chamber 930 through the condensed water pipeline 920, causing the wine vapor in the refrigerant pipeline 940 to condense into wine, and finally the wine exits through the liquid outlet pipeline 265 and the second stop valve 950. This improves the utilization rate of thermal energy.

[0062] After a certain period of time, the second distillation is carried out, and the two distillations are continuous. During the second distillation, the heating of the right distillation kettle 300 is stopped, and the left distillation kettle 400 is heated. At this time, the second three-way valve 1050 is controlled so that the wine vapor in the left distillation kettle 400 passes through the second three-way valve 1050 and enters the second series kettle pipeline 1040, and then enters the right distillation kettle 300. After the two parts of wine vapor converge, the first three-way valve 1030 is controlled so that the wine vapor enters the right rectifying tower 500 through the third connecting pipeline 1060 for rectification and preliminary condensation. After that, it passes through the third three-way valve 1120 and the fifth connecting pipeline 1110 to complete flavoring in the right flavoring tower 700, and then enters the gas transmission mechanism 260 through the third stop valve 1130 and the fourth stop valve 1140. Finally, the two parts of wine vapor converge and are sent into the heat medium pipeline 230 through the right distillation kettle 300. This process enables the heat of the distillation residue in the right distillation kettle 300 to enter the left distillation kettle 400, avoiding heat loss.

[0063] During the continuous production process, the above steps are repeated, causing the right distillation kettle 300 and the left distillation kettle 400 to alternate in distillation. The seventh connecting pipeline 1190 can be selectively installed and is connected to the fourth stop valve 1140 and the sixth stop valve 1180. By connecting to the refrigerant pipeline 940 through the seventh connecting pipeline 1190, the wine vapor can be directly sent into the refrigerant pipeline 940 without passing through the heat medium pipeline 230.

[0064] It should be noted that the above-mentioned preheating kettle 200, right distillation kettle 300, right rectifying tower 500, right flavoring tower 700 and cooling tower 900, as well as each valve component, are conventional technical means, and their specific structures and working principles will not be elaborated.

[0065] Embodiment 2 is an improved description based on Embodiment 1. Specifically, please refer to Figures 1 - 8 , the preheating kettle 200 further includes a gas transmission mechanism 260. The gas transmission mechanism 260 includes a first connecting pipeline 261 and a buffer tank 263. The first connecting pipeline 261 is communicated with the outlet of the heat medium pipeline 230;

[0066] The fourth stop valve 1140 and the sixth stop valve 1180 are connected to the buffer tank 263 through the second connecting pipe 262. The second connecting pipe 262 is provided with a circulation pump 264, and the circulation pump 264 is connected to the inlet of the heat medium pipe 230. The first connecting pipe 261 is provided with a liquid outlet pipe 265, and a temperature control valve 266 is provided between the first connecting pipe 261 and the liquid outlet pipe 265.

[0067] The preheating kettle 200 further includes a circulation mechanism 270, which includes a first reflux pipe 271 disposed on the first connecting pipe 261 and a second reflux pipe 272 disposed on the buffer tank 263, and the first reflux pipe 271 and the second reflux pipe 272 are both connected to the second connecting pipe 262;

[0068] The circulation mechanism 270 also includes a valve member 273, which is slidably connected to the first connecting pipe 261, the first return pipe 271 and the second return pipe 272. The valve member 273 is elastically connected to the first connecting pipe 261 through a spring 274. A first liquid channel 275 and a second liquid channel 276 are opened in the valve member 273. The first connecting pipe 261 is connected to the second connecting pipe 262 through the first liquid channel 275, and the second return pipe 272 is connected to the second connecting pipe 262 through the second liquid channel 276.

[0069] In this embodiment, in order to further improve the utilization efficiency of the heat of the wine vapor in the heat medium pipe 230, a gas delivery mechanism 260 and a circulation mechanism 270 are added to allow the wine vapor to continuously circulate in the heat medium pipe 230 to release heat, and then release it into the refrigerant pipe 940 when it reaches a certain level.

[0070] Specifically, refer to Figures 6 - 8 , Figure 8 In the figure, the second connecting pipe 262 is divided into two parts, the left half is located at the right end of the circulation pump 264, and the right half is located above the buffer tank 263.

[0071] A first return pipe 271 extends from the first connecting pipe 261 connected to the tail end of the heat medium pipe 230 and is connected to the second connecting pipe 262. A second return pipe 272 is extended from the second connecting pipe 262 and is connected to the interior of the buffer tank 263. The left part of the valve member 273 is slidably installed in the first connecting pipe 261, the middle part of the valve member 273 is slidably installed in the first return pipe 271, and the right part of the valve member 273 is slidably installed in the second return pipe 272.

[0072] Under normal conditions, the valve member 273 is located at the lower side, and its right and middle parts respectively block the joints of the first return pipeline 271 and the second connection pipeline 262, as well as the joints of the second return pipeline 272 and the second connection pipeline 262. At this time, the air flow direction is from the second connection pipeline 262 to the heat medium pipeline 230 and the first connection pipeline 261 and then stops. The joint of the first connection pipeline 261 and the liquid outlet pipeline 265 is also blocked by the temperature control valve 266. The temperature control valve 266 is opened and closed by temperature. At this time, the temperature has not dropped below the threshold value, and the temperature control valve 266 is in the closed state.

[0073] After a certain amount of wine vapor is injected into the heat medium pipeline 230, the internal air pressure therein resists the elastic force of the spring 274 and pushes the valve member 273 to move upward, so that the upper ends of the middle and right parts of the valve member 273 block the inner diameter of the second connection pipeline 262.

[0074] At this time, two new air paths are formed. One is that the wine vapor in the heat medium pipeline 230 is pumped by the circulation pump 264, enters the first connection pipeline 261 from the heat medium pipeline 230, then enters the first liquid channel 275, and returns to the circulation pump 264 through the leftward opening on the upper side of the first liquid channel 275 for circulation.

[0075] Until the temperature of the gas circulating in the heat medium pipeline 230 drops to the threshold value of the temperature control valve 266, the liquid outlet pipeline 265 opens, and the wine vapor is injected into the refrigerant pipeline 940.

[0076] The other air path is that the wine vapor in the second connection pipeline 262 is first temporarily stored in the buffer tank 263. After the pressure in the heat medium pipeline 230 decreases and the valve member 273 drops and resets after the temperature control valve 266 is opened, the wine vapor temporarily stored in the buffer tank 263 is then injected into the heat medium pipeline 230 together.

[0077] Example 3. Specifically, please refer to Figures 1 - 8 A distillation method for a distillation device used in whiskey brewing, including the following steps:

[0078] S1. Pour the original wine into the preheating chamber 220 through the original wine pipeline 240. Part of the original wine flows into the right distillation kettle 300 and the left distillation kettle 400 through the perfusion pipeline 1010. Control the water vapor generated by the steam generator 1210 to heat the right distillation kettle 300 and the left distillation kettle 400 through the fifth three-way valve 1230, so that the original wine in the right distillation kettle 300 and the left distillation kettle 400 is distilled into wine vapor;

[0079] S2. Control the fifth three-way valve 1230 to stop delivering steam to the left distillation kettle 400, so that the left distillation kettle 400 stops heating while the right distillation kettle 300 continues to heat. Control the wine vapor in the right distillation kettle 300 to be delivered into the left distillation kettle 400 through the first series kettle pipeline 1020, heat the left distillation kettle 400 by using the heat of the wine vapor, and make the wine vapor in the right distillation kettle 300 and the left distillation kettle 400 converge and be delivered into the second connecting pipeline 262 through the sixth connecting pipeline 1150 and the sixth stop valve 1180;

[0080] After the original wine in the right distillation kettle 300 is distilled, inject the original wine into the preheating kettle 200, the right distillation kettle 300 and the left distillation kettle 400, and control the right distillation kettle 300 to stop heating while the left distillation kettle 400 continues to heat, so that the wine vapor in the left distillation kettle 400 is delivered into the right distillation kettle 300 through the second series kettle pipeline 1040, and make the wine vapor in the right distillation kettle 300 and the left distillation kettle 400 converge and be delivered into the second connecting pipeline 262 through the fifth connecting pipeline 1110 and the fourth stop valve 1140;

[0081] S3. The wine vapor in the second connecting pipeline 262 enters the heat medium pipeline 230. The original wine in the preheating chamber 220 exchanges heat with the wine vapor in the heat medium pipeline 230 to preheat the original wine in the preheating chamber 220 and precool the wine vapor in the heat medium pipeline 230. Then, the wine vapor in the heat medium pipeline 230 enters the refrigerant pipeline 940 for condensation and the wine is discharged through the liquid outlet pipeline 265.
