Description

Technical Field

[0001] This invention belongs to the field of brewing equipment, specifically a high-purity baijiu deep extraction system. Background Technology

[0002] In my country, the production of baijiu (white liquor) primarily employs solid-state fermentation and distillation. The fermented mash is fed into the still of a still, where steam is generated at the bottom for distillation, extracting the alcohol and aroma components. During distillation, the heat exchange and propulsion of the steam at the bottom cause the alcohol and aroma components in the mash to gradually concentrate, forming alcoholic vapor that rises layer by layer from the bottom to the top of the still. Simultaneously, the alcohol components are continuously concentrated, and a large number of alcohol-soluble aroma components present in the mash are continuously extracted. Therefore, the aroma component extraction efficiency is higher and more complete in the upper part of the still than in the lower part. Ideally, the distillation process involves the alcohol components being concentrated layer by layer within the still, resulting in a uniform and consistent concentration, maximizing the extraction and enrichment of aroma components from the mash. However, in actual operation, due to the large volume inside the still, the loose structure of the solid mash varies, and the density is inconsistent in some areas. The direction and power of water vapor or alcohol vapor traveling from bottom to top are also unstable. At the same time, human operation factors can easily lead to excessive steam pressure in the mash, meaning that water vapor or alcohol vapor is too deep below the surface of the mash, which affects the uniform diffusion and rising effect of water vapor or alcohol vapor. All of these situations can easily lead to uneven steam transmission in the still, as well as unstable steam transmission power and local phenomena of excessively fast or slow steam transmission. This disrupts the ideal state of uniform enrichment and aroma enhancement of alcohol components layer by layer, resulting in low alcohol content, low aroma enhancement efficiency, and a large amount of off-flavors in the aroma components of the wine, which seriously affects the yield and quality of the wine.

[0003] Several existing technologies for alcohol distillation exist, such as a Chinese patent application (201210244607.5) which discloses a multi-stage distillation apparatus for extracting aroma from alcohol. This apparatus includes interconnected primary and secondary stills and a cooler, with each still and cooler connected via a vapor delivery pipe. The method involves feeding steam into the bottom of the primary still to distill the brewing mash. The resulting vapor then enters the secondary still from the bottom to continue distilling the mash. The further enriched and refined vapor is then output from the top and re-enters the bottom of the next secondary still. This process is repeated until the enriched and refined vapor is collected in the cooler and becomes alcohol. Although this technical solution can achieve the distillation of the mash in the rectifier, it cannot fully distill the mash. At the same time, this technical solution cannot use the already distilled alcohol vapor to circulate distillation in a single still, resulting in inconsistent alcohol distillation efficiency in the first-stage still, second-stage still, and third-stage still, which reduces the alcohol yield of the mash and limits the use of this invention. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a high-purity deep extraction system for baijiu (Chinese liquor), primarily used to improve the purity of alcohol distillation. This invention utilizes a distillation tank in conjunction with a circulation device to re-distill the distilled alcohol vapor from the mash; simultaneously, it employs a moving block and spring mechanism to cause the vapor to drive the storage box to vibrate vertically, thus reducing the footprint of the invention.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a high-purity baijiu deep extraction system, which includes a distillation tank, a circulation device, a collection tank, and a controller. The circulation device is connected to the right side of the distillation tank and is used to perform secondary distillation on the alcohol distilled in the distillation tank. The collection tank is used to collect the alcohol vapor in the distillation tank, and the controller is used to control the operation of the circulation device.

[0006] The distillation chamber includes a first upper base plate, a first side plate, and a first lower base plate. The first upper base plate is mounted on the upper surface of the first lower base plate via the first side plate. The distillation chamber has a cubic structure and contains multiple first-stage distillation devices and multiple second-stage distillation devices. The first-stage and second-stage distillation devices are staggered on the inner surface of the first side plate in a top-to-bottom order. When the steam distills the mash in the distillation chamber, the first-stage distillation devices, in conjunction with the second-stage distillation devices, cause the steam to move along a curved path, increasing the steam's travel distance within the distillation chamber and improving the alcohol distillation efficiency. The upper surface of each first-stage distillation device is provided with a first-stage opening slot at intervals. The first-stage opening slot is square and contains a storage box. An air inlet device is located on the bottom plate of the first-stage opening slot. The bottom of the storage box is covered with micro-pores, and the air inlet device is used to supply steam to the bottom of the storage box. The micro-pores are used for steam to circulate within the storage box. The lees are distilled; the second distillation unit serves the same purpose as the first distillation unit, and the storage boxes in the second distillation unit and the first distillation unit are staggered horizontally; the first distillation unit, in conjunction with the second distillation unit, ensures that the lees on the upper surface of the storage box can fully contact the steam, further improving the efficiency of alcohol distillation; the first bottom plate is equipped with a first pressure gauge, which is used to detect the pressure value in the distillation chamber. When the pressure value in the distillation chamber reaches the set value, the alcohol vapor in the distillation chamber is transported to the collection box; the first side plate has a first vent on the upper left, a steam port on the lower left, a second vent on the upper right, and a third vent on the lower right; the first vent is connected to the collection box through a first solenoid valve; the steam port is used to supply water vapor into the distillation chamber; the second vent is connected to the third vent through a circulation device. During operation, steam distills the mash in the distillation tank through the steam inlet. When the steam pressure in the distillation tank reaches the set value, the pressure gauge sends the data back to the controller. The controller then closes the steam inlet. Simultaneously, the circulation device transports the alcohol vapor from the top of the distillation tank to the bottom for repeated distillation of the mash. A heating device is installed at the bottom of the distillation tank to maintain the internal temperature within a set range. As more alcohol evaporates from the tank, the internal gas pressure increases accordingly. When the pressure gauge detects that the pressure in the distillation chamber is greater than the set value, the controller opens the No. 1 solenoid valve to deliver alcohol vapor to the collection tank. When the alcohol vapor level in the distillation chamber is less than the set value, the controller closes the No. 1 solenoid valve. The distillation chamber continues to distill the mash inside the chamber. When the mash in the distillation chamber reaches the predetermined distillation time, hot air enters the distillation chamber through the steam port. At the same time, the controller opens the No. 1 solenoid valve. The hot air, in conjunction with the steam port and the No. 1 solenoid valve, delivers the alcohol vapor in the distillation chamber to the collection tank for liquefaction.

The spring, in cooperation with the fourth push rod and the fourth push plate, ensures that the sealing rubber gasket is always subjected to a pushing force, enabling the sealing rubber gasket to seal the gap between the storage box and the first opening groove. At the same time, when the storage box shakes horizontally, the extrusion device, in cooperation with the sealing rubber gasket, can maintain the fit between the sealing rubber gasket and the storage box.

The circulation device 2 is connected to the right side of the distillation tank 1, and the circulation device 2 is used to perform secondary distillation on the alcohol distilled in the distillation tank 1. The collection tank 4 is used to collect the alcohol vapor in the distillation tank 1, and the controller is used to control the operation of the circulation device 2.

[0023] The distillation tank 1 includes an upper base plate 11, a side plate 12, and a lower base plate 13. The upper base plate 11 is mounted on the upper surface of the lower base plate 13 via the side plate 12.

The primary distillation devices 14 and secondary distillation devices 15 are staggered on the inner surface of the side plate 12 in a top-to-bottom order. When steam distills the mash in the distillation tank 1, the primary distillation devices 14 and secondary distillation devices 15 interact with each other. The device is designed to guide the vapor along a curved path, increasing its travel distance within the distillation chamber 1 and improving the distillation efficiency of the alcohol.

The controller then closes steam port 121. Simultaneously, the circulation device 2 transports the alcohol vapor from the top of the distillation tank 1 to the bottom of the distillation tank 1 for repeated distillation of the mash. A heating device is installed at the bottom of the distillation tank 1 to maintain the internal temperature of the distillation tank 1 within a set range. As more and more alcohol evaporates in the distillation tank 1, the gas pressure inside the distillation tank 1 also increases, and pressure gauge 111...
