Description

Technical Field

[0001] The present application relates to the technical field of liquor manufacturing equipment, and in particular to a strong alcohol distillation equipment. Background Art

[0002] Spirits such as whiskey, vodka, and rum are a type of strong distilled liquor made from grains such as barley or molasses, aged in oak barrels for many years, and then blended into a strong distilled liquor with a concentration of about 43-60 degrees.

[0003] At present, domestic production of whiskey generally adopts the brewing process of the intermittent method to obtain spicy and stimulating spirits. The new wine distilled by the ordinary intermittent method generally has a low alcohol purity, contains impurities such as alcohols, acids, esters, etc. that affect the flavor of the wine, is relatively spicy, has a bad taste, and is not suitable for use in the field of condiments and flavored wines. In order to obtain purer, better-flavored and better-tasting whiskey, vodka, rum and other spirits, the existing technology uses distillation to increase energy consumption, separates unwanted flavor substances (such as acids), and then adds a certain proportion of flavor substances to blend to obtain the finished wine with the desired flavor. The above process has high energy consumption and will produce a large amount of high-concentration wastewater. The treatment of high-concentration wastewater requires special dilution equipment, which is costly and difficult to handle.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] See also Figure 1 The present application provides a strong alcohol distillation device, which can be used for the continuous production of strong alcohol such as whiskey, vodka, rum, etc. The alcohol content of the liquor produced by the distillation device can reach more than 96%, greatly reducing impurities in the liquor and improving the quality of the liquor.

[0036] Specifically, the distillation equipment includes a distillation tower, a condenser and a steam pipeline.

[0037] The distillation tower includes a feed port for inputting materials to be distilled, a first discharge port and a first reflux port. The first discharge port is used to output the wine liquid stripped out, and the first reflux port is used for reflux condenser to condense the separated reflux liquid.

[0038] The first discharge port can be arranged at the top of the distillation tower, which is more conducive to the stripping of the wine liquid out of the distillation tower.

[0039] The first reflux port is located below the first discharge port. The rising steam can exchange heat with the reflux liquid to extract the alcohol component in the reflux liquid again.

[0040] The condenser includes a feed end and a discharge end. The feed end is connected to a first discharge port located at the upper part of a distillation tower through a first discharge pipe. The discharge end is connected to a first reflux port on the distillation tower through a first reflux pipe, so that the reflux liquid after condensation and separation can re-enter the distillation tower and be extracted again, reducing the waste of materials and reducing the concentration of alcohol in the waste liquid, thereby reducing the difficulty of treating the waste liquid.

[0041] The discharge end of the condenser can be connected to a third discharge pipe. The finished wine after condensation and separation can be discharged through the third discharge pipe for collection and storage.

[0042] The inner wall of the distillation tower can be made of copper.

[0043] The heat exchange pipes in the condenser for the wine vapor to pass through are made of copper.

[0044] The first discharge pipe is made of copper.

[0045] The first return pipe is made of copper.

[0046] The third discharge pipe is made of copper.

[0047] During the distillation process of whiskey and other spirits, methyl sulfide in the liquor is difficult to separate, and methyl sulfide has a pungent odor, which affects the flavor and taste of the finished liquor. Copper can replace methyl sulfide in the liquor and improve the taste and flavor of the liquor.

[0048] The steam pipeline is connected to an external steam source and is connected to the distillation tower below the feed inlet, and can transport steam into the distillation tower to heat the material in the distillation tower.

[0049] In the above, after the steam enters the distillation tower through the steam pipe, it comes into direct contact with the material. The driving force of the high-temperature and high-pressure steam from bottom to top can evaporate the light components (such as alcohol) in the material entering the distillation tower from the feed inlet, lift it upward, and then enter the condenser from the first discharge pipe and be separated by the condenser.

[0050] Generally, during the distillation process, heavy components such as fusel oil that affect the taste and flavor of the wine will be extracted from the wine. During the process of mass transfer and heat transfer between the steam and the material, the steam will carry over the heavy components extracted from the material and be condensed into liquid, which will flow back to the bottom of the distillation tower, thereby reducing the content of heavy components in the finished wine and improving the quality of the wine.

[0051] In addition, a large amount of steam condensate flowing back to the bottom of the distillation tower will significantly dilute the residual material at the bottom of the tower, reducing the COD (chemical oxygen demand) value in the residual material, thereby reducing the cost and difficulty of residual material treatment.

[0052] Furthermore, the above-mentioned distillation equipment uses a steam pipeline to directly introduce steam into the distillation tower to heat the material, and there is no need to set a reboiler in the distillation tower, which simplifies the structure of the equipment and reduces the equipment cost.

[0053] In order to further improve the flavor of the wine, a container for holding flavor materials such as spices can be set in the distillation tower. The container can be set above the steam pipe so that the steam can extract the flavor components in the spices during the rising process, thereby making the wine have a richer taste and flavor.

[0054] The distillation equipment may further include a steam distributor. The steam distributor is disposed in the distillation tower and connected to the inner wall of the distillation tower. The steam distributor is in communication with the steam pipeline and is provided with a plurality of steam outlets. The steam outlets can discharge the steam discharged from the steam pipeline into the distillation tower, so that the steam can be more evenly distributed inside the distillation tower, thereby improving the stripping effect of the steam on the material and thus increasing the concentration of the liquor.

[0055] In some embodiments of the present application, the steam outlet is arranged toward the upper part of the distillation tower, so that the steam discharged from the steam pipe can move directly upward toward the upper part of the distillation tower, and the pressure in the steam pipe can serve as a driving force for the steam to be transported upward to the distillation tower, so that the steam can contact the material entering from the feed inlet more quickly, thereby reducing energy loss and improving the stripping effect.

[0056] The steam distributor can be made of copper to reduce the content of formaldehyde in the wine and improve the taste and flavor of the wine.

[0057] For example, the steam distributor can be made of copper. Copper has a high copper content, good plasticity, and is easy to process. Copper also has excellent corrosion resistance, ensuring that the steam distributor has a long service life.

[0058] like Figure 2 As shown, in some embodiments of the present application, multiple steam outlets are distributed into multiple rows, and each row of steam outlets is evenly distributed along the radial direction of the steam distributor, so that the multiple rows of steam outlets are radially distributed with the center of the steam distributor as the point. Alternatively, multiple steam outlets are arranged equidistantly around the radial direction of the distillation tower. In this way, through the steam distributor, the steam entering the distillation tower from the steam pipe can be more evenly distributed in the distillation tower, thereby improving the steam stripping effect of the steam on the material.

[0059] The steam outlets may also be distributed in an array along the radial direction of the distillation tower.

[0060] In some embodiments of the present application, Figure 1 As shown, the distillation tower includes a tower bottom, a distillation section and a tower top head, and the distillation section is arranged between the tower bottom and the tower top head.

[0061] A plurality of tower plates are arranged in the distillation section, and the plurality of tower plates are arranged in sequence and at intervals along the axial direction of the distillation section. Two adjacent tower plates are arranged in a staggered manner, which can increase the residence time of the material on the tower plates, thereby improving the heat exchange effect between steam and material.

[0062] A liquid receiving pan may be provided in the distillation tower. The liquid receiving pan is connected between the tower plate and the inner wall of the distillation tower. The liquid receiving pan is arranged along the radial direction of the distillation tower, and the installation height of the liquid receiving pan is slightly lower than the installation height of the tower plate to which it is connected.

[0063] A downcomer is provided on the side with a gap between the tower plate and the inner wall of the distillation tower. The downcomer extends from the top of the tower plate to the bottom of the tower plate. A gap is left between the downcomer and the inner wall of the distillation tower. A liquid sealing disc is provided at the lower end of the downcomer connected to the tower plate closest to the tower bottom. The liquid sealing disc is arranged along the radial direction of the distillation tower to receive the wine flowing down from the downcomer connected to the tower plate closest to the tower bottom, so as to prevent the wine from flowing directly into the tower bottom and causing turbulence.

[0064] The part of the downcomer located above the tower plate can keep part of the wine collected from the liquid receiving tray on the tower plate, ensuring the gas-liquid mass transfer and heat transfer effect on the tower plate.

[0065] When the height of the wine on the tower plate exceeds the height of the downcomer, the wine will overflow along the downcomer to the liquid receiving tray connected to a tower plate below.

[0066] The steam distributor is located under a tray closest to the bottom of the tower. The steam pipe is connected to the side wall of the bottom of the tower, so that the steam can move upward from the bottom of the distillation tower, improving the heat exchange effect between the steam and the material.

[0067] The feed inlet is set on the distillation section. The steam moves from bottom to top and can strip out the light components in the material when passing through the material entering from the feed inlet.

[0068] The height position of the feed port on the distillation section can be adjusted according to actual production needs to obtain liquor with different tastes and flavors.

[0069] Furthermore, a plurality of wine discharge channels may be provided on the distillation tower. The plurality of wine discharge channels are arranged above the feed port and are spaced apart along the height direction of the distillation tower. The extracted wine vapor may be discharged through different wine discharge channels to obtain finished wine products of different concentrations.

[0070] The rectifying section may be provided with a second discharge port and a second reflux port. The rectifying device further comprises a heat exchanger. The heat exchanger comprises a feed side and a discharge side, the feed side of the heat exchanger is connected to the second discharge port via a second discharge pipe, and the discharge side of the heat exchanger is connected to the second reflux port via a second reflux pipe. The heat exchanger is connected to the rectifying section of the rectifying tower, and can locally heat the material near the second discharge port in the rectifying tower, thereby increasing the vaporization of light components in the material, and thus increasing the concentration of the liquor.

[0071] The heat exchanger is connected to the distillation section of the distillation tower. Compared with the overall bottom-up thermal storage heating, it shortens the movement path of the material and saves more energy.

[0072] The second discharge pipe and the second return pipe can be made of copper.

[0073] The second reflux port can be arranged above the second discharge port. The material enters the heat exchanger from the bottom and is discharged from the top, so that the wine vapor after passing through the heat exchanger can move upward until it is discharged from the first discharge port, thus preventing the heated wine vapor from entering the heat exchanger again and avoiding an increase in energy consumption.

[0074] In some embodiments of the present application, the feed port can be arranged above the second reflux port. The temperature of the wine vapor heated by the heat exchanger is relatively high, and the material input into the distillation tower from the feed port can be stripped, thereby further increasing the concentration of light components in the wine vapor and improving thermal efficiency.

[0075] In some embodiments of the present application, the heat exchange pipes through which the wine vapor passes in the heat exchanger can be made of copper, so as to reduce the content of formaldehyde in the wine and improve the taste and flavor of the wine.

[0076] In some embodiments of the present application, a waste outlet is provided at the lower part of the distillation tower, and the waste outlet is provided below the steam pipe. The waste outlet can be provided at the bottom of the tower kettle, so as to facilitate the discharge of all the residual substances in the distillation tower. The waste outlet can be connected to a waste outlet pipe, and the waste outlet pipe can also be connected to a residual substance processing device, so that the residual substances after the distillation of the liquor can be directly processed through the waste outlet.

[0077] In summary, the present application connects a steam pipe at the lower part of the distillation tower, and directly transports steam into the distillation tower through the steam pipe, so that the rising steam can directly contact the material entering the distillation tower, and strip out the light components such as alcohol in the material, and the steam stripped wine moves upward as a whole through the driving force of the steam from bottom to top, and enters the condenser through the first discharge pipe for condensation and separation to obtain the finished wine, which simplifies the structure of the equipment and reduces the equipment cost. During the mass transfer and heat transfer process, the steam can also condense the heavy components in the material and reflux them to the bottom of the tower, reducing the content of the heavy components in the finished wine and improving the quality of the wine. A large amount of steam condensate can also dilute the residual substances in the bottom of the tower, reducing the difficulty and cost of handling the residual substances in the distillation process. By connecting a heat exchanger to the distillation section of the distillation tower, the local material in the distillation tower can be heated, the concentration of the wine can be increased, and energy consumption can be saved.
