Description

Technical Field

[0001] This utility model relates to a double distillation apparatus, and more particularly to a high-tower baijiu double distillation apparatus. Background Technology

[0002] Double distillation, also known as re-distillation, is a distillation technique used in baijiu brewing equipment. It involves re-distilling baijiu that has undesirable qualities, such as a raw material taste, off-flavors, or cloudiness. Therefore, double distillation is particularly important for improving the taste of baijiu with poor quality. Furthermore, because the first and last distillates tend to have higher levels of methanol and fusel oils, re-distillation is necessary to reduce these harmful substances and minimize the health risks associated with baijiu consumption. Utility Model Content

[0003] The purpose of this invention is to provide a high-tower baijiu (Chinese liquor) redistilling still. It can effectively redistill baijiu, separating low-boiling-point and high-boiling-point substances, reducing acidity and removing impurities, thereby improving the quality of the baijiu.

[0004] The technical solution of this utility model is as follows: A high-tower baijiu re-distillation apparatus includes a distillation pot, a swan neck, a Lynn arm, and a first conveying main pipe arranged sequentially on the rear side of the distillation pot. The first conveying main pipe is equipped with multiple sets of first three-way valves, which are connected to the inlet of a first distillation column. A first reflux main pipe is provided on one side of the first distillation column, and a first connecting branch pipe is provided on the first reflux main pipe to connect with the reflux port of each layer of the first distillation column. A control valve is provided on the first connecting branch pipe. A second conveying main pipe with multiple sets of second three-way valves is provided on one side of the first distillation column for conveying alcohol vapor. A second distillation column is provided on one side of the second conveying main pipe, and a second reflux main pipe is provided on one side of the second distillation column. A second connecting branch pipe is provided on the second reflux main pipe to connect with the reflux port of each layer of the second distillation column. A condenser and a liquor outlet are arranged sequentially on the rear side of the second distillation column.

[0005] In the aforementioned high-tower baijiu re-distillation apparatus, a head distillation tank, a core distillation tank, and a tail distillation tank are respectively provided behind the distillation outlet. The head distillation tank is connected to the head distillation temporary storage tank through a conveying pipe, and the tail distillation tank is connected to the tail distillation temporary storage tank through a conveying pipe.

[0006] In the aforementioned high-tower baijiu re-distillation apparatus, the lower ends of the first reflux main pipe and the second reflux main pipe are connected to a reflux temporary storage tank via a delivery pipe.

[0007] In the aforementioned high-tower baijiu re-distillation apparatus, a CIP cleaning pump is provided on one side of the distillation pot.

[0008] In the aforementioned high-tower baijiu re-distillation apparatus, the first and second distillation columns have 15 layers.

[0009] Compared with the prior art, the present invention has the following advantages: This application involves heating and re-distilling baijiu in a distillation pot. The resulting alcohol vapor is then altered by combining a first three-way valve on the first delivery main pipe with a control valve on one side of the first reflux main pipe, and a second three-way valve on the second delivery main pipe with a control valve on one side of the second reflux main pipe. This allows for different usage modes of the distillation column, changing the number of layers the alcohol vapor passes through. This significantly improves the separation of low-boiling-point and high-boiling-point substances, as well as reducing acidity and removing impurities during the baijiu re-distillation process.

Detailed Implementation

[0012] Example. A high-tower baijiu double-distillation apparatus, configured as follows: Figure 1-2 As shown, the system includes a distillation pot 1. Behind the distillation pot 1, a swan neck 2, a Lynn arm 3, and a first conveying main pipe 4 are sequentially arranged. Multiple sets of first three-way valves 5 are installed on the first conveying main pipe 4, which are connected to the inlet of a first distillation column 6. A first reflux main pipe 7 is located on one side of the first distillation column 6. A first connecting branch pipe 8 connected to the reflux port of each layer of the first distillation column 6 is installed on the first reflux main pipe 7. A second conveying main pipe 11, equipped with multiple sets of second three-way valves 10, is located on one side of the first distillation column 6. A second distillation column 12 is located on one side of the second conveying main pipe 11. A second reflux main pipe 13 is located on one side of the second distillation column 12. A second connecting branch pipe 14 connected to the reflux port of each layer of the second distillation column 12 is installed on the second reflux main pipe 13. Control valves 9 are installed on the first connecting branch pipe 8 and the second connecting branch pipe 14. A condenser tower 15 and a liquor outlet 16 are sequentially arranged behind the second distillation column 12.

[0013] The outlet 16 is equipped with a head tank 17, a core tank 18 and a tail tank 19 on its rear side. The head tank 17 is connected to the head storage tank 20 through a conveying pipe, and the tail tank 19 is connected to the tail storage tank 21 through a conveying pipe.

[0014] The lower ends of the first return main pipe 7 and the second return main pipe 13 are connected to the return temporary storage tank 22 via a delivery pipe.

[0015] A CIP cleaning pump 23 is provided on one side of the distillation pot 1.

[0016] The first distillation column 6 and the second distillation column 12 have 15 layers each.

[0017] The working principle of this utility model is as follows: This application is used for the re-distillation of baijiu (Chinese white liquor), especially for baijiu of poor quality containing many impurities. The baijiu is added to the distillation pot 1, which can be heated by steam jacket heating, internal heat exchange plate heating, or external heater circulation heating. The alcohol vapor generated by heating enters the first conveying main pipe 4 through the swan neck 2 and Lynn arm 3. The first conveying main pipe 4 is equipped with multiple sets of first three-way valves 5. By controlling the opening and closing of the first three-way valves 5, the position of the alcohol vapor entering the first distillation column 6 can be controlled. The control valve 9 on the first connecting branch pipe 8 on one side of the first reflux main pipe 7 can be controlled to adjust the flow position and number of layers of the alcohol vapor in the first distillation column 6. The control principle of the second three-way valves 10 and control valve 9 on both sides of the second distillation column 12 is the same as that on the side of the first distillation column 6, so as to adjust the flow position and number of layers of the alcohol vapor in the second distillation column. This changes the number of layers through which the alcohol vapor flows, which can play a significant role in the separation of low-boiling-point substances and high-boiling-point substances, as well as the reduction of acidity and removal of impurities during the re-distillation of baijiu. Finally, the liquor is discharged through the condenser 15 and the outlet 16. Behind the outlet 16 are a head tank 17, a center tank 18, and a tail tank 19, which collect different portions of the liquor. The liquor in the head tank 17 and the tail tank 19 are sent to the head storage tank 20 and the tail storage tank 21, respectively, for further processing. The reflux liquid in the first reflux manifold 7 and the second reflux manifold 13 flows to the reflux storage tank 22 for collection. Finally, the reflux liquid is pumped back to the distillation pot for redistillation by connecting a high / low fork switch on one side of the reflux storage tank 22 to a circulation pump.
