Description

Technical Field

[0001] This utility model belongs to the field of beverage brewing equipment, and in particular relates to a vodka production equipment. Background Technology

[0002] Vodka is the world's second most consumed distilled spirit. It has a clean taste and is suitable for drinking neat or blending with other spirits. The market is currently large and continues to grow. The main processing method for vodka involves fermenting grains (wheat, corn, rye, etc.) or tubers (potatoes), followed by distillation to increase the ethanol purity to over 95% vol, while reducing methanol, acetaldehyde, esters, and higher alcohols to below legal limits. The resulting product is then filtered through activated carbon and diluted and blended.

[0003] Vodka production requires multi-stage, continuous large-scale distillation columns, typically 3 to 5 stages, with each stage containing more than 25 purification trays. While this equipment offers high purification efficiency, it involves significant initial investment, large footprint, and high energy consumption, and requires large-scale continuous production, making small-batch flexible production impossible. Conversely, using small stills to produce vodka, due to their limited purification capacity, makes it difficult to produce vodka that meets the highest international standards.

[0004] Therefore, how to achieve flexible batch production of vodka while ensuring high quality has become the biggest challenge for product innovation. Utility Model Content

[0005] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0006] This utility model proposes a vodka production equipment that solves the technical problems of existing vodka production equipment having large footprint and energy consumption, while small-scale production equipment cannot guarantee product quality. It has the characteristics of flexible small-batch production of vodka, and the vodka produced meets the highest international standards.

[0007] This utility model discloses a vodka production device, comprising: A vacuum still has a vacuum still inlet and a vacuum still outlet. The base spirit enters the vacuum still through the vacuum still inlet for the first distillation. A pot still has a first pot still inlet, a second pot still inlet, and a pot still outlet, with the first pot still inlet connected to the vacuum still outlet. A column still has a column still inlet and a column still outlet, with the column still inlet connected to the pot still outlet; The core still has a core still inlet, a first core still outlet, and a second core still outlet. The core still inlet is connected to the outlet of the tower still, and the first core still outlet is connected to the inlet of the second pot still.

[0008] In some embodiments, the column still has ≥12 trays.

[0009] In some embodiments, a degassing tower is also included, having a degassing tower inlet and a degassing tower outlet, the degassing tower outlet being connected to the vacuum distillation unit inlet.

[0013] In some embodiments, a dilution filtration device is also included, with the core tank connected to the dilution filtration device via the outlet of the second core tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a vodka production device. By setting up a vacuum still, pot still, and tower still, the device first uses a vacuum still to distill the beer fermentation liquid, obtaining alcohol with an alcohol content of 60-65% vol. Then, a pot still connected in series with a tower still is used for a second distillation of the 60-65% vol alcohol, obtaining a spirit with an alcohol content of 92-93% vol.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0017] This utility model embodiment provides a vodka production device. Figure 1 This is a schematic diagram of the structure of a vodka production equipment according to an embodiment of the present invention.

[0018] refer to Figure 1 As shown, a vodka production apparatus includes a vacuum still 1, which has a vacuum still inlet and a vacuum still outlet. The base spirit enters the vacuum still 1 from the vacuum still inlet for the first distillation.

[0019] The aforementioned vodka production equipment first uses vacuum still 1 to perform a first distillation of the beer fermentation liquid to obtain alcohol with an alcohol content of 60-65% vol, which is beneficial to improving the distillation efficiency of subsequent pot and tower distillation.

[0020] The aforementioned vacuum still 1 is a device that uses the difference in boiling points of substances to achieve separation in a vacuum environment. The core principle is to reduce the boiling point of substances by lowering the pressure. Its structure can be a tower type or other existing vacuum still 1 structures, as long as it can achieve low-pressure vacuum distillation.

[0021] A vodka production apparatus includes a pot still 2, which has a first pot still inlet, a second pot still inlet, and a pot still outlet, wherein the first pot still inlet is connected to the vacuum still outlet.

[0022] The pot still 2 described above is an intermittent distillation device used to extract high-purity alcohol, commonly used in the brewing of spirits such as brandy, whiskey, and gin. Its working principle is as follows: the alcohol is evaporated by heating the raw spirit; the vapor is refluxed through a separator for purification, then condensed into liquid. Through multiple distillations, the "heads" (low-boiling-point impurities), "heart" (high-purity alcohol), and "tails" (high-boiling-point impurities) are separated. The heart obtained from distillation in pot still 2 enters column still 3 for further processing; that is, the outlet of the pot still is used to output the heart obtained from distillation in pot still 2.

[0023] In some embodiments, the pot still 2 includes a distillation pot (mostly made of copper with a reflux design), a preheater (for energy saving), and a condenser (with serpentine cooling). Its specific structure is the same as that of existing pot stills, as long as it can meet the distillation requirements.

[0024] A vodka production apparatus includes a column still 3 having a column still inlet and a column still outlet, the column still inlet being connected to the pot still outlet.

[0025] The aforementioned column still 3 is a device that uses gas-liquid two-phase contact to separate mixtures. Its core principle is based on the difference in boiling points of the components; by heating, the lower-boiling-point components evaporate and condense, ultimately separating the different components. Its structural form is the same as existing column still 3, as long as it meets the distillation requirements.

[0026] In some embodiments, the column still 3 has ≥12 trays. In fact, the more trays, the better the distillation and purification effect. However, more trays also increase the height of the equipment, reducing its flexibility. Therefore, considering both distillation effect and equipment flexibility, it is preferable that the column still 3 has 12 trays. A vodka production apparatus includes a core tank 4, which has a core tank inlet, a first core tank outlet, and a second core tank outlet. The core tank inlet is connected to the outlet of the column still, and the first core tank outlet is connected to the inlet of the second pot still.

[0027] By connecting the outlet of the first pot still to the inlet of the second pot still, the purpose of multiple distillations can be achieved by connecting the pot still 2 in series with the tower still 3, thus avoiding the problem of further increasing the floor space caused by setting up multiple pot stills 2 in series with the tower still 3.

[0028] The aforementioned vodka production equipment, by setting up a vacuum still 1, a pot still 2, and a column still 3, first uses the vacuum still 1 to perform a first distillation of the beer fermentation liquid, obtaining alcohol with an alcohol content of 60-65% vol. Then, the pot still 2, connected in series with the column still 3, performs a second distillation of the alcohol with an alcohol content of 60-65% vol, obtaining a core spirit with an alcohol content of 92-93% vol. Finally, the pot still 2, connected in series with the column still 3, performs a third distillation of the core spirit with an alcohol content of 92-93% vol. The third distillation yields a spirit with an alcohol content >95% vol. A fourth distillation is then performed using a pot still 2 connected in series with a tower still 3 to obtain a spirit with an alcohol content ≥96% vol. This process, employing a combination of low-pressure vacuum, pot still, and tower still distillation techniques, produces vodka that meets the highest international standards. This not only solves the problem that high-quality vodka can only be produced using large-scale equipment, but also introduces a new technology for producing high-quality vodka using beer fermentation liquid, enabling flexible small-batch production of vodka.

[0029] In some embodiments, a degassing tower 5 is also included, having a degassing tower inlet and a degassing tower outlet, the degassing tower outlet being connected to the vacuum distillation unit inlet.

[0030] The degassing tower 5 is a tank with a flow-through device at the top, allowing the beer to flow down the inner wall of the tank. Carbon dioxide is removed by controlling the vacuum level. The degassing tower 5 used in this invention can be any existing type of degassing tower, as long as it can remove carbon dioxide from the beer fermentation liquid.

[0031] In some embodiments, a heating device 6 is also included, which has a heating device inlet and a heating device outlet, with the heating device outlet connected to the degassing tower inlet. Beer fermentation liquid with an alcohol content of 5-10% vol first enters the heating device 6 and is heated to 30-40°C. Then, it enters the degassing tower 5 through the heating device outlet to remove carbon dioxide, and then enters the vacuum still 1 through the degassing tower outlet for the first distillation.

[0032] In some embodiments, an alcohol tank 7 is also included, through which the vacuum still 1 is connected to the pot still 2. The alcohol tank 7 is used to store alcohol with an alcohol content of 60-65% vol obtained from the first distillation in the vacuum still 1.

[0033] In some embodiments, the alcohol tank 7 includes an alcohol tank inlet and an alcohol tank outlet, the alcohol tank inlet being connected to the outlet of the vacuum still and the alcohol tank outlet being connected to the inlet of the first pot still.

[0034] In some embodiments, a dilution filtration device is also included, with the core tank 4 connected to the dilution filtration device via the outlet of the second core tank.

[0035] The process of producing vodka using the aforementioned vodka production equipment includes: Using malt and water as the main raw materials, beer fermentation liquid with an alcohol content of 5-10% vol is obtained after saccharification and fermentation for 5-7 days; The beer fermentation liquid is fed into vacuum still 1 and distilled for the first time at 38-42℃ and a vacuum of 80-100 mbar to obtain alcohol with an alcohol content of 60-65% vol. 60-65% vol alcohol is fed into pot still 2 connected in series with a column still 3 (12 purification trays in total) for a second distillation at atmospheric pressure. The heads, hearts, and tails are collected according to Table 1 to obtain a heart of 92-93% vol alcohol. The above steps are repeated twice, and the two 92-93% vol heart of vol alcohol samples are combined (using the same pot still + column still 3 set; the reason for repeating the distillation twice is to obtain a sufficient amount of heart of vol alcohol for a third distillation). The heart of the spirit with an alcohol content of 92-93% vol is fed into a pot still 2 connected in series with a column still 3 (a total of 12 purification trays) and distilled for the third time under normal pressure. The heads, heart, and tails are collected according to Table 1 to obtain the heart of the spirit with an alcohol content of >95% vol. The head, heart, and tail of the spirit with an alcohol content > 95% vol were fed into a pot still 2 connected in series with a column still 3 (a total of 12 purification trays) and distilled for the fourth time under normal pressure. The heads, heart, and tails were collected according to Table 1 to obtain the heart with an alcohol content ≥ 96% vol. Dilute the filler spirit with an alcohol content of ≥96% vol to ≥37.5% vol using reverse osmosis water, according to the target alcohol content of the product; then perform freeze filtration, optionally with series activated carbon filtration, to obtain the finished vodka with an alcohol content of ≥37.5% vol.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
