Description

Technical Field

[0001] This application relates to the field of brewing technology, and in particular to a brewing distillation apparatus. Background Technology

[0002] Chinese Baijiu is hailed as one of the world's six major distilled spirits. Its unique characteristic lies in the fact that many aroma compounds, which coexist with the main component alcohol, are also concentrated and extracted into the spirit during distillation. Distillation is a crucial step in Baijiu production, responsible for the recovery and purification of these compounds. "Aroma develops through fermentation, aroma is enhanced through distillation"—distillation is a vital stage in Baijiu brewing.

[0003] Solid-state fermentation of baijiu is a unique traditional Chinese process. The distillation apparatus is the key component in solid-state baijiu brewing. Currently, distilleries commonly use integrated distillation units, which consist of a bottom pot, a still, and a cooler. The bottom pot serves as the heating element. During distillation, the heating device in the bottom pot generates steam by direct steam injection and heat exchange with water to heat the mash. However, this method is prone to producing spot-like high-temperature steam during the steam heating process, which can lead to a certain probability of scorching, thus affecting the taste and quality of the baijiu.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] like Figure 1 and Figure 2 As shown, this application provides a brewing distillation apparatus, comprising: The bottom pot 1 is equipped with a steam heat exchange tube 10. The steam heat exchange tube 10 includes an input section 101, a heat exchange section 102 and an output section 103. The input section 101 passes through one side of the bottom pot 1 and is connected to the steam supply device 11. The output section 103 passes through the lower part of one side of the bottom pot 1 and extends out. The heat exchange section 102 is arranged in a spiral shape on the horizontal plane. The bottom pot 1 has a pot opening 110 at the top. Distillation still 2, which is matched and connected to the pot opening 110; Condenser 3 is connected to still 2 via gas pipe 20; Collect wine barrel 4, which is connected to the wine output end of condenser 3.

[0018] In use, the steam supply device 11 first supplies high-temperature steam to the input section 101 of the steam heat exchange tube 10. As the steam flows through the heat exchange section 102, its large surface area allows for efficient heat exchange with the water inside the bottom pot 1, heating the water and generating steam. After heating, the steam exits from the output section 103 and either enters a subsequent processing unit or is discharged. The steam generated in the bottom pot 1 rises and is transferred to the still 2 through the pot opening 110, heating the mash in the still 2. The alcohol and flavor compounds in the mash rise with the steam, generating steam containing alcohol and flavor compounds. This steam enters the condenser 3 through the steam pipe 20, where it is condensed into liquid liquor by a cooling medium (such as cold water). Finally, the liquor flows into the collection tank 4 through the output end of the condenser 3, completing the distillation and collection process.

[0019] The device of this application heats the water in the bottom pot 1 by setting a heat exchange tube 10 including a vortex heat exchange section 102 in the bottom pot 1, and heats the water in the bottom pot 1 by exchanging heat with the water in the bottom pot 1 through the heat exchange section 102 to generate steam, and then distills the mash in the still 2. The steam generated by this indirect heat exchange method is more uniform and can effectively avoid the generation of point-like or block-like steam clusters. It can overcome the drawback of existing solid-state baijiu distillation devices that use direct steam injection to heat the water in the bottom pot, which easily generates point-like high-temperature steam, causing the pot to burn and affecting the quality of the liquor.

[0020] like Figure 3 and Figure 4 As shown, optionally, the still 2 includes an inner still 21 and an outer still 22 covering the inner still 21; The inner steamer 21 is composed of multiple layers of stacked grates 211; The outer steamer 22 is used to completely cover the inner steamer 21. The outer steamer 22 includes a cylindrical body 221 and a steamer cover 222 on the top of the cylindrical body 221. The top of the steamer cover 222 has a steam outlet 2201.

[0021] In this application, the inner still 21 is composed of multiple stacked grates 211, which are typically perforated plates or mesh structures used to support the brewing raw materials and allow steam to pass through evenly, thereby improving distillation efficiency. The outer still 22 completely covers the inner still 21, serving to insulate, seal, and provide structural support. The outer still 22 includes a cylindrical body 221 and a lid 222. The cylindrical body 221 is a cylindrical or similarly shaped container, and the lid 222 covers the top of the cylindrical body 221, forming a closed space. A steam outlet 2201 is provided at the top of the lid 222 for exporting the steam generated in the inner still 21 to the external steam pipe 20 or other connecting components. This split design facilitates disassembly and cleaning, while effectively controlling the steam flow and temperature distribution during the distillation process.

[0022] During operation, the mash is placed on the multi-layered grates 211 of the inner still 21. This stacked structure ensures uniform distribution of the raw materials and smooth steam penetration. When the bottom pot 1 provides heat, the raw materials in the inner still 21 evaporate, producing steam containing alcohol and flavor compounds. The outer still 22's cylinder 221 and lid 222 together form a sealed environment, preventing steam leakage and maintaining internal pressure, thereby improving distillation efficiency. Steam rises from the inner still 21 and exits through the steam outlet 2201 of the lid 222, entering the subsequent condensation stage. The cover design of the outer still 22 also reduces heat loss, ensuring the stability of the distillation process.

[0023] like Figure 4 As shown, optionally, steam outlet 2201 is connected to steam pipe 20.

[0024] In this application, the steam outlet 2201 is located at the top of the still cover 222 of the still 2, serving as a channel for steam discharge. It is directly connected to the gas guide pipe 20 to ensure that steam is smoothly transmitted from the still 2 to the condenser 3.

[0025] like Figure 5 As shown, optionally, the steam outlet 2201 is connected to the steam pipe 20 and the vertically arranged first condenser pipe 23 respectively through the three-way plug valve 100. The pipe above the three-way plug valve 100 and the pipe below the three-way plug valve 100 are connected through a bypass pipe 2200 equipped with a one-way valve 200. The connection point at the upper end of the bypass pipe 2200 is located close to the three-way plug valve 100. A receiving dish 223 is provided inside the still lid 222. The bottom of the receiving dish 223 is connected to the first liquid guide pipe 220 passing through the side of the still lid 222, and is connected to the receiving tank 24 located outside the still 2 through the first liquid guide pipe 220. The receiving dish 223 is located directly below the steam outlet 2201.

[0026] In this application, Figure 5This is for illustrative purposes only. In actual production, the first liquid guide pipe 220 can be connected to the receiving tank 24 or other convenient locations for receiving liquid, according to specific requirements.

[0027] In this application, during the initial stage of distillation or when it is necessary to remove impurities from the still, the three-way stopcock valve 100 can be operated to connect the steam outlet 2201 to the first condenser 23. This portion of the early distillate or steam containing impurities enters the first condenser 23 for condensation. The condensed liquid (such as heads or impurities) flows downward under gravity and falls into the receiving dish 223 located directly below the steam outlet 2201. This portion of the condensed dripping liquid is collected and flows by gravity to the external receiving tank 24 (correspondingly, to prevent alcohol-containing vapor from leaking out through the first liquid guide pipe 220, a valve can be installed on the first liquid guide pipe 220 to be opened when liquid needs to be collected. Similarly, the first liquid guide pipe 220 can be made of a transparent material such as glass for easy observation), and is then recovered to the corresponding head collection device. When the main distillation process is underway, the three-way stopcock valve 100 is operated to connect the steam outlet 2201 to the gas guide pipe 20. At this time, the main alcohol vapor generated in the still 2 is guided to the condenser 3 for condensation and collection through the gas guide pipe 20. The vertically arranged first condenser pipe 23 is isolated in this mode. In addition, the inventors found that during the main distillation process, some high-boiling-point flavor substances in the mash are difficult to enter the condenser 3 through the gas guide pipe 20, resulting in the produced liquor having a lower quality in terms of taste and flavor than that of traditional still condensation. Therefore, during the main distillation stage, the three-way stopcock valve 100 is adjusted so that it can simultaneously connect the first condenser pipe 23 and the gas guide pipe 20. In this way, some vapor containing high-boiling-point flavor substances will be condensed in the first condenser pipe 23 and then fall into the receiving dish 223 through the bypass pipe 2200 and be collected in the receiving tank 24. After distillation, the liquor in the receiving tank 24 and the collecting barrel 4 can be mixed as needed to improve the taste and quality of the product.

[0028] If the condensed liquid in the first condenser 23 accumulates and flows down, the one-way valve 200 can prevent the fluid (steam or liquid flowing down through the one-way valve 200) from flowing back up through the bypass pipe 2200.

[0029] The first condenser tube 23 can be a spherical condenser tube, a serpentine condenser tube, or the like.

[0030] like Figure 2 As shown, optionally, the pot opening 110 extends upward to form a pot ring 111, and a support frame 112 is provided inside the pot ring 111. The support frame 112 is used to support the inner steamer 21. A water seal groove 113 is provided along the outer periphery of the pot ring 111, and the bottom of the outer steamer 22 is in contact with the bottom of the water seal groove 113.

[0031] In this application, the pot ring 111, as an extension of the top of the bottom pot 1, enhances structural stability and sealing. The support frame 112, typically made of heat-resistant material such as a metal mesh or bracket, supports the weight of the inner steamer 21 and allows steam to rise evenly. The water seal groove 113 is an annular groove that can be filled with water. The bottom of the outer steamer 22 is immersed in the water seal groove 113 to form a water seal, preventing steam leakage and maintaining internal pressure.

[0032] During operation, when the bottom pot 1 is heated, steam enters the still 2 through the pot opening 110. The structure of the support frame 112 prevents the inner still 21 from directly contacting the bottom of the bottom pot 1, reducing the risk of scorching. The water in the water seal tank 113 contacts the bottom of the outer still 22, forming a sealed barrier that effectively prevents steam leakage.

[0033] like Figure 6 As shown, optionally, the condenser 3 includes a housing 31; the housing 31 is open at the top and closed at the bottom, with a cooling medium inlet 3101 at the lower part of one side and a cooling medium outlet 3102 at the upper part. A condenser 32 is provided inside the housing 31. The condenser 32 includes an upper input header 321 and a lower output header 322. The input header 321 and the output header 322 are connected by at least one second condenser pipe 310. The input header 321 is connected to the air duct 20; The output header 322 is connected to the inner bottom of the housing 31, and the bottom of the output header 322 is connected to the wine collection barrel 4 through the second liquid guide pipe 320.

[0034] In this application, the open top of the housing 31 facilitates maintenance and observation, while the closed bottom prevents leakage.

[0035] During operation, steam enters the input header 321 through the steam guide pipe 20 and then disperses into the second condenser pipe 310. The second condenser pipe 310 is surrounded by a cooling medium within the housing 31. As the steam flows inside the pipe, it exchanges heat with the cooling medium outside, condensing into liquid wine. The condensed wine collects in the output header 322 and flows into the collection tank 4 through the second liquid guide pipe 320. The cooling medium (such as cold water) enters the housing 31 through the cooling medium inlet 3101, flows past the outside of the second condenser pipe 310, and exits from the cooling medium outlet 3102, thus condensing the steam.

[0036] The second condenser tube 310 is a straight tube, which achieves cooling and condensation by exchanging heat with the cooling medium inside the shell 31.

[0037] like Figure 7 As shown, optionally, the output section 103 of the steam heat exchanger tube 10 is also connected to the makeup water tank 12; The water tank 12 is also connected to the bottom pot 1.

[0038] In this application, during operation, when steam is discharged from the output section 103 of the steam heat exchanger tube 10, its residual heat is transferred to the makeup water tank 12, heating the water inside. The preheated water flows into the bottom pot 1 through a connecting pipe, serving as distillation water or makeup liquid. This reduces the initial heating load on the bottom pot 1, shortens the preheating time, and reduces energy consumption.

[0039] In order to ensure sealing during use, the equipment of this application can be sealed at the connection of components by means of appropriate sealing structures, such as food-grade rubber gaskets.

[0040] Example 1

[0041] A brewing distillation apparatus, the working process of which is as follows: In use, an appropriate amount of water is injected into the bottom pot 1, and the mash is evenly spread on the grate 211 of the inner still 21. The mash should be spread loosely, evenly, and flat. The grate is then stacked as needed and placed on the pot opening 110. After the still is filled, the outer still 22 is covered, and an appropriate amount of water is injected into the water seal trough 113 to seal the outer still 22. Then, the heating and distillation process begins. During distillation, the steam supply device 11 first provides high-temperature steam to the input section 101 of the steam heat exchange tube 10. When the steam flows through the heat exchange section 102, because the heat exchange section 102 is coiled in a vortex shape inside the bottom pot 1, its large surface area allows for efficient heat exchange with the water in the bottom pot 1, thereby heating the water in the bottom pot 1 to generate steam. The generated steam rises and enters the still 2 through the pot opening 110, heating the mash spread in the inner still 21. The alcohol and flavor compounds in the mash rise with the steam, producing steam containing alcohol and flavor compounds. This steam enters the input header 321 of the condenser 3 through the steam guide pipe 20, and then disperses into the second condenser tube 310. At the same time, cooling medium (such as cooling circulating water) is injected into the shell 31 through the cooling medium inlet 3101. The steam entering the second condenser tube 310 exchanges heat with the cooling medium outside the tube and condenses to form liquor. This liquor collects in the output header 322, and then flows out through the second liquid guide pipe 320 to the collection tank 4 for collection (in this process, the heads obtained from the initial distillation can also be collected separately).

[0042] During the distillation process, the steam used to heat the water in the bottom pot 1 is output from the output section 103 of the steam heat exchange tube 10 and enters the water replenishment tank 12. The steam is heated along with the water in the water replenishment tank 12. The heated water in the water replenishment tank 12 can replenish the water in the bottom pot 1 in real time to prevent the pot from drying out.

[0043] Example 2

[0044] A brewing distillation apparatus, the working process of which is as follows: In use, an appropriate amount of water is injected into the bottom pot 1, and the mash is evenly spread on the grate 211 of the inner still 21. The mash should be spread loosely, evenly, and flat. The grate is then stacked as needed and placed on the pot opening 110. After the still is filled, the outer still 22 is covered, and an appropriate amount of water is injected into the water seal trough 113 to seal the outer still 22. Then, the heating and distillation process begins. During distillation, the steam supply device 11 first provides high-temperature steam to the input section 101 of the steam heat exchange tube 10. When the steam flows through the heat exchange section 102, because the heat exchange section 102 is coiled in a vortex shape inside the bottom pot 1, its large surface area allows for efficient heat exchange with the water in the bottom pot 1, thereby heating the water in the bottom pot 1 to generate steam. The generated steam rises and enters the still 2 through the pot opening 110, heating the mash spread in the inner still 21. The alcohol and flavor substances in the mash rise with the steam, generating steam containing alcohol and flavor substances.

[0045] During the initial distillation stage or when impurities need to be removed from the still, the three-way stopcock valve 100 can be operated to connect the steam outlet 2201 to the first condenser 23. This portion of the early distillate or steam containing impurities enters the first condenser 23 for condensation. The condensed liquid (such as heads or impurities) flows downward under gravity and falls into the receiving dish 223 located directly below the steam outlet 2201. This portion of the condensed dripping liquid is collected and flows by gravity to the external receiving tank 24, and then recovered to the corresponding head collection device. During the main distillation process, the three-way stopcock valve 100 is operated to connect the steam outlet 2201 to the gas guide pipe 20. At this time, the main alcohol vapor generated in the still 2 is guided to the condenser 3 for condensation and collection through the gas guide pipe 20. The first condenser 23 is isolated in this mode. Furthermore, the inventors discovered that during the main distillation process, some high-boiling-point flavor substances in the mash are difficult to enter the condenser 3 through the gas inlet pipe 20, resulting in the produced liquor being inferior in terms of taste, flavor, and other qualities compared to traditional condenser condensation. Therefore, during the main distillation stage, the three-way stopcock valve 100 can be adjusted to simultaneously connect the first condenser pipe 23 and the gas inlet pipe 20. This allows some vapor containing high-boiling-point flavor substances to condense in the first condenser pipe 23 and then fall into the receiving dish 223 through the bypass pipe 2200 and be collected in the receiving tank 24. After distillation, the liquor in the receiving tank 24 and the collecting barrel 4 can be mixed as needed to improve the taste and quality of the product.

[0046] The steam entering the condenser 3 through the steam guide pipe 20 is first fed into the header 321 and then dispersed into the second condenser pipe 310. At the same time, cooling medium (such as cooling circulating water) is injected into the housing 31 through the cooling medium inlet 3101. The steam entering the second condenser pipe 310 exchanges heat with the cooling medium outside the pipe and condenses to form wine. This wine is collected in the output header 322 and then flows out through the second liquid guide pipe 320 to the wine collection tank 4 for collection.

[0047] During the distillation process, the steam used to heat the water in the bottom pot 1 is output from the output section 103 of the steam heat exchange tube 10 and enters the water replenishment tank 12. The steam is heated along with the water in the water replenishment tank 12. The heated water in the water replenishment tank 12 can replenish the water in the bottom pot 1 in real time to prevent the pot from drying out.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
