The steam mechanism 1200 includes a steam generator 1210 . An eighth connecting pipe 1220 is provided on the steam generator 1210 . The steam generator 1210 is connected to the right distillation kettle 300 and the left distillation kettle 400 through the eighth connecting pipe 1220 .

[0030] In this embodiment, a liquid level meter may be installed on the preheating kettle 200 to observe the change of the liquid level inside the preheating kettle 200.

[0031] The right still 300 is used to distill the original wine. An additional cavity or pipeline other than the original wine can be provided in the right still 300 to be connected to the eighth connecting pipeline 1220. The steam generator 1210 is used to generate water vapor, and the water vapor enters the right still 300 through the eighth connecting pipeline 1220.

[0032] The original wine in the right still 300 is heated by water vapor. The reflux cone 320 and the gooseneck 330 are used to improve the distillation effect, so that the purity of the wine vapor coming out of the gooseneck 330 is improved. The exhaust pipe 340 and the sewage pipe 350 are used for exhaust and sewage discharge during and after the distillation process. The installation angle of the gooseneck 330 can be switched between right angles, acute angles, and obtuse angles. Defoaming equipment such as tooth-type, spiral-type, and stirring blades can also be installed in the right still 300 to assist distillation. The right still 300 can also be equipped with a condensed water circulation device between the evaporator and the steam generator 1210. Part of the steam and condensed water after the hot steam is distilled and cooled can be recycled, and its heat can be regularly transferred back to the steam generator 1210 to achieve heat recovery. The steam condensed water is pure water. Recycling condensed water can increase the service life of the steam generator 1210 and reduce scaling.

[0033] The right distillation tower 500 can be a plate tower or a packed tower, which can improve the purity of the wine vapor flowing out of the right distillation tower 500. The right aroma tower 700 is used to add flavor substances such as flower petals to enrich the taste of whiskey.

[0034] First, the original wine can be injected into the preheating chamber 220 through the original wine pipeline 240 by a liquid pump, and then part of the original wine is diverted to the right still 300 and the left still 400 through the injection pipeline 1010. The steam generator 1210 generates steam to heat the right still 300 and the left still 400, so that the original wine in the two is distilled.

[0035] After distillation for a certain period of time, the fifth three-way valve 1230 is controlled to stop supplying water vapor to the left distillation kettle 400, so that the left distillation kettle 400 stops heating and concentrates on heating the right distillation kettle 300. At this time, the first three-way valve 1030 is controlled to allow the wine vapor in the right distillation kettle 300 to pass through the gooseneck pipe 330 and the first three-way valve 1030 to enter the first series kettle pipeline 1020, and then enter the left distillation kettle 400. After the two parts of wine vapor converge, the second three-way valve 1050 is controlled to allow the wine vapor to pass through the fourth connecting pipeline 1070 to enter the left distillation tower 600 for distillation and preliminary condensation, and then pass through the fourth three-way valve 1160 and the sixth connecting pipeline 1150 to complete the fragrance in the left fragrance tower 800, and then pass through the fifth stop valve 1170 and the sixth stop valve 1180 to enter the gas transmission mechanism 260, and then enter the heat medium pipeline 230 through the gas transmission mechanism 260.

[0036] The wine vapor entering the heat medium pipe 230 exchanges heat with the cold original wine in the preheating chamber 220, preheating the original wine and precooling the wine vapor. Then the wine vapor in the heat medium pipe 230 enters the refrigerant pipe 940, and condensed water such as tap water can be poured into the cooling chamber 930 through the condensed water pipe 920, so that the wine vapor in the refrigerant pipe 940 is condensed into wine, and finally the wine is discharged through the liquid outlet pipe 265 and the second stop valve 950. The utilization rate of heat energy is improved.

[0037] After a certain period of time, the second distillation is carried out, and the two distillations are uninterrupted. During the second distillation, the heating of the right still 300 is stopped, and the left still 400 is heated. At this time, the second three-way valve 1050 is controlled to allow the wine vapor in the left still 400 to enter the second still pipe 1040 through the second three-way valve 1050, and then enter the right still 300. After the two parts of the wine vapor converge, the first three-way valve 1030 is controlled to allow the wine vapor to enter the right distillation tower 500 through the third connecting pipe 1060 for distillation and preliminary condensation, and then pass through the third three-way valve 1120 and the fifth connecting pipe 1110 to complete the aroma in the right aroma tower 700, and then enter the gas transmission mechanism 260 through the third stop valve 1130 and the fourth stop valve 1140. Finally, the two parts of the wine vapor converge and are sent to the heat medium pipe 230 through the right still 300. This process allows the heat of the distillation residue in the right still 300 to enter the left still 400, avoiding heat loss.

[0038] In the continuous production process, the above steps are repeated so that the right still 300 and the left still 400 are distilled alternately. The seventh connecting pipeline 1190 can be installed optionally, and the fourth stop valve 1140 and the sixth stop valve 1180 of the seventh connecting pipeline 1190 are connected. By connecting the seventh connecting pipeline 1190 with the refrigerant pipeline 940, the wine vapor can be directly sent to the refrigerant pipeline 940 without passing through the heat medium pipeline 230.

[0039] It should be supplemented that the above-mentioned preheating kettle 200, right distillation kettle 300, right distillation tower 500, right fragrance tower 700 and cooling tower 900 as well as various valve components are conventional technical means, and their specific structures and working principles are not described in detail.

[0040] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 8 The preheating kettle 200 further includes a gas delivery mechanism 260, which includes a first connecting pipe 261 and a buffer tank 263, and the first connecting pipe 261 is connected to the outlet of the heat medium pipe 230; 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. 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; 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.

[0041] 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.

[0042] Specifically, refer to Figure 6-Figure 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.

[0043] 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.

[0044] In normal state, the valve member 273 is at the lower side, and the right and middle parts thereof respectively block the connection between the first return pipe 271 and the second connecting pipe 262 and the connection between the second return pipe 272 and the second connecting pipe 262. At this time, the airflow direction is from the second connecting pipe 262 to the heat medium pipe 230 and the first connecting pipe 261 and then stops, and the connection between the first connecting pipe 261 and the liquid outlet pipe 265 is also blocked by the temperature control valve 266. The temperature control valve 266 is opened and closed by temperature control. At this time, the temperature has not dropped below the threshold, and the temperature control valve 266 is in a closed state.

[0045] After a certain amount of wine vapor is injected into the heat medium pipe 230 , the internal air pressure counteracts the elastic force of the spring 274 , pushing the valve member 273 upward, so that the upper ends of the middle and right parts of the valve member 273 block the inner diameter of the second connecting pipe 262 .

[0046] At this time, two new gas paths are formed, one of which is that the wine vapor in the heat medium pipe 230 is pumped through the circulation pump 264, enters the first connecting pipe 261 from the heat medium pipe 230, and then enters the first liquid channel 275, and returns to the circulation pump 264 through the opening on the upper left side of the first liquid channel 275 for circulation.

[0047] When the temperature of the gas circulating in the heat medium pipe 230 drops to the threshold value of the temperature control valve 266 , the liquid outlet pipe 265 is opened and the wine vapor is injected into the refrigerant pipe 940 .

[0048] The other gas path is that the wine vapor in the second connecting pipe 262 is temporarily stored in the buffer tank 263. After the temperature control valve 266 is opened, the pressure in the heat medium pipe 230 is reduced, causing the valve member 273 to drop and reset, and then the wine vapor temporarily stored in the buffer tank 263 is injected into the heat medium pipe 230 together.

[0049] For details, please refer to Example 3.
