Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] As mentioned in the background, a still is used in the distillation process of baijiu brewing. In existing still designs, both the still barrel and the lid have concave structures. The concave shape of the lid is embedded in the concave shape of the still barrel, and the still is sealed by a strip of cloth bag filled with rice husks and lees. This design has problems: due to the concave structure of the still barrel, and the fact that the rice husks or lees in the cloth bag are prone to falling off and are difficult to distribute evenly, the sealing effect of the still is affected. In the initial stage of distillation, the temperature difference between the lid and the steam may cause steam condensation, flowing back into the concave area of the still barrel, wetting the cloth bag and causing liquor loss, as well as affecting the reusability of the cloth bag. Furthermore, long-term use may lead to water accumulation in the concave area of the still barrel, and the temperature may rise during distillation, potentially posing a risk of burns to the operator. To better solve this problem, the inventors of this application propose a new type of still. The still in this application allows the steam in the lid to condense and flow back into the still barrel, thereby reducing the loss of liquor and lowering the risk of burns caused by water overflowing from the grooves of the still barrel due to condensation of steam.
[0030] like Figure 1 As shown, Figure 1This is a schematic diagram of the structure of a still in one embodiment of this application. The still includes a still 100, a still lid 200, and a sealing element 300. The still 100 provides space for the fermented mash, the still lid 200 closes the still 100, and the sealing element 300 is disposed between the still 100 and the still lid 200 to improve the sealing performance between them. In this embodiment, the still allows steam in the still lid 200 to flow back into the still 100, thereby reducing liquid loss and lowering the risk of burns caused by water overflowing after steam condensation.
[0031] For details, please refer to Figure 1 and Figure 2 As shown, the upper end of the steamer 100 is provided with a mating part 110, wherein the upper side of the mating part 110 forms an installation groove 111; the steamer cover 200 is provided with a mating groove 210, and when the steamer cover 200 mates with the steamer 100, the mating part 110 is located in the mating groove 210; the sealing member 300 is provided in the installation groove 111, and the height of the sealing member 300 exceeds the depth of the installation groove 111.
[0032] In this embodiment, the still 100 has a mating part 110 at its upper end, and a mounting groove 111 is formed on the upper side of the mating part 110. A sealing element 300 is provided in the mounting groove 111, and the still cover 200 has a mating groove 210. When the still cover 200 mates with the still 100, the mating part 110 is located in the mating groove 210, and the height of the sealing element 300 exceeds the depth of the mating groove 210, thereby achieving an effective seal. The design of the mating groove 210 on the still lid 200 and the mating part 110 on the still 100, meaning that after the edge of the mating groove 210 mates with the mating part 110, one side edge of the mating groove 210 can be located inside the still 100. This allows the condensed liquid in the still lid 200 to flow smoothly back into the still 100 along the mating part 110, avoiding the liquid loss caused by condensed steam falling into the groove of the still 100 in existing solutions. Furthermore, the solution in this embodiment also solves the risk of steam overflow and scalding caused by the groove design of the still 100 in the prior art.
[0033] In one embodiment, see Figure 2 As shown, the mating part 110 is an upwardly protruding arc-shaped structure, and the mating groove 210 includes an arc-shaped bottom 211 and an extension 212. The arc-shaped bottom 211 mates with the mating part 110, and the extension 212 extends toward the bottom of the steamer 100.
[0034] In this embodiment, by designing the mating portion 110 of the steamer 100 as an upwardly convex arc-shaped structure, the arc-shaped mating portion 110 can tightly fit with the arc-shaped bottom 211 of the mating groove 210 on the steamer cover 200. This also allows condensed steam on the surface of the mating portion 110 to quickly flow back into the steamer 100. Furthermore, the arc-shaped structure of the mating portion 110 provides a better transition effect, reducing the risk of scratches during contact. When the steamer cover 200 and the steamer 100 are combined, the arc-shaped bottom 211 of the mating groove 210 and the arc-shaped structure of the mating portion 110 engage with each other. Simultaneously, the mating groove 210 of the steamer cover 200 presses against the sealing element 300, compressing the sealing element 300 and thus enhancing the sealing effect. The combination of the arc-shaped mating portion 110 and the sealing element 300 ensures the sealing performance between the steamer cover 200 and the steamer 100, effectively preventing steam leakage. After the steam condenses in the still lid 200, the extension 212 of the matching groove 210 extends towards the bottom of the still 100, thereby effectively guiding the condensed steam back into the still 100 along the extension 212, avoiding the overflow of condensed steam and loss of wine, and also reducing the risk of operators being scalded.
[0035] In one embodiment, the length of the extension 212 of the mating groove 210 is greater than or equal to 3 centimeters.
[0036] In this embodiment, the extension 212 of the mating groove 210 of the still lid 200 is designed to be greater than or equal to 3 cm in length to ensure that the condensed steam can effectively flow back into the still 100 along the extension 212. The extension 212 provides a sufficient guiding path to prevent the condensed steam from overflowing due to an insufficiently short path during the return flow. Researchers have suggested in simulations and actual analyses that when the length of the extension 212 is less than 3 cm, the return path may be insufficient, causing the steam to fail to overcome gravity and flow back into the still 100 smoothly due to surface tension and liquid adhesion. In this case, steam may accumulate and overflow at the end of the extension 212, increasing the risk of steam overflow and liquid loss. In addition, steam overflow may also pose a risk of burns to the operator. By designing the extension 212 to be greater than or equal to 3 cm, a sufficiently long return path for the condensed steam is ensured to effectively guide the steam back. It should also be noted that the appropriate length of the extension 212 ensures ease of assembly and disassembly, avoiding assembly difficulties that may result from an excessively long design.
[0037] In one embodiment, when the mating groove 210 of the steamer cover 200 mates with the mating part 110 of the steamer bucket 100, the gap between the mating groove 210 and the mating part 110 is less than or equal to 1 cm.
[0038] In this embodiment, when the mating groove 210 of the steamer lid 200 is engaged with the mating portion 110 of the steamer bowl 100, the gap between the mating groove 210 and the mating portion 110 is designed to be less than or equal to 1 cm. This design aims to optimize the sealing performance between the steamer lid 200 and the steamer bowl 100. A larger gap may cause steam to escape through the gap under high temperature and high pressure conditions, because steam tends to diffuse along the path of least resistance during distillation. By designing the gap to be smaller, the resistance of steam passing through the gap is increased, thereby effectively preventing steam from escaping and significantly enhancing the sealing effect.
[0039] In one embodiment, see Figure 2 As shown, a blocking part 310 is provided at one end of the seal 300 away from the bottom of the mounting groove 111. The blocking part 310 is used to block the gap between the mounting groove 111 and the seal 300.
[0040] In this embodiment, the still is equipped with a shielding part 310 at the end of the sealing member 300 away from the bottom of the mounting groove 111. The shielding part 310 is used to shield the gap between the mounting groove 111 and the sealing member 300, thereby effectively solving the problem of steam leakage caused by the gap between the sealing member 300 and the mounting groove 111. By adding the shielding part 310 to the sealing member 300, when the mating groove 210 of the still cover 200 is engaged with the mating part 110 in the still 100, the shielding part 310 can be pressed tightly by the mating groove 210 of the still cover 200, thereby sealing the gap between the mounting groove 111 and the sealing member 300 and reducing the risk of steam entering the mounting groove 111.
[0041] In one embodiment, the seal 300 is made of rubber.
[0042] In this embodiment, the still is significantly enhanced in sealing performance by using rubber as the material for the sealing element 300. Due to its excellent elasticity and flexibility, rubber can effectively fill the minute gaps between the mating groove 210 of the still 200 and the mating part 110 of the still 100 under pressure when the still lid 200 is joined to the still 100, thereby improving the sealing effect. The heat resistance of the rubber material ensures that the sealing element 300 maintains its physical properties during high-temperature distillation, resisting deformation or damage, thus providing a durable sealing effect. By selecting rubber as the material for the sealing element 300, the problem of steam leakage caused by insufficient sealing material performance in the prior art is solved. At the same time, the reusability of rubber material also improves the economic efficiency of the still.
[0043] In one embodiment, see Figure 1 As shown, the cover 200 has a conical structure, and the cross-section of the cover 200 gradually increases towards the steamer 100.
[0044] In this embodiment, the still lid 200 is designed with a conical structure, and the cross-section of the still lid 200 gradually increases in the direction towards the still 100. This design allows steam to converge upwards along the inner wall of the still lid 200 during distillation. The conical structure effectively reduces steam condensation loss by reducing the contact area between the steam and the inner wall. At the same time, the gradually increasing cross-section of the still lid 200 helps the condensed liquid flow smoothly back into the still 100, avoiding the accumulation of condensate on the inner wall of the still lid 200, thereby reducing liquid loss.
[0045] In one embodiment, see Figure 1 As shown, a connecting component 400 is also provided between the steamer cover 200 and the steamer bucket 100.
[0046] In this embodiment, a stable connection between the still lid 200 and the still 100 is achieved by providing a connecting component 400 between the still lid 200 and the still 100. The design of the connecting component 400 effectively prevents the still lid 200 from shifting due to steam pressure or external disturbances during distillation, which significantly improves the sealing performance of the still. The connecting component 400 ensures that the still lid 200 and the still 100 maintain a consistent relative position, avoiding poor sealing caused by positional misalignment. Furthermore, the connecting component 400 can absorb minor deformations caused by thermal expansion or external forces to a certain extent, ensuring the continuous effectiveness of the seal between the still lid 200 and the still 100.
[0047] In one embodiment, see Figure 1 As shown, the connecting assembly 400 includes a lifting lug 410 and a lifting hook 420. The lifting lug 410 is disposed on the still 100, and the lifting hook 420 is disposed on the still lid 200. By providing the lifting lug 410 on the still 100 and the lifting hook 420 on the still lid 200, a reliable connection is achieved between the still lid 200 and the still 100. After the lifting hook 420 moves downward toward the lifting lug 410, it engages with the lifting lug 410 to secure it, ensuring that the still lid 200 will not shift due to steam pressure or external disturbances during distillation. The solution in this embodiment effectively improves the sealing performance of the still, prevents steam leakage, and maintains the stability of the distillation process. When the still lid 200 needs to be separated from the still 100, the lifting hook 420 is separated from the lifting lug 410, and then the lifting hook 420 is moved upward, thus separating the still lid 200 from the still 100. The lifting hook 420 can move up and down via a threaded connection. For example, the side wall of the hook may be threaded, and the cover 200 may have a threaded hole, thus enabling the hook to lift. Of course, the lifting function of the lifting hook 420 is not limited to this method.
[0048] In one embodiment, both the steamer lid 200 and the steamer bucket 100 are made of stainless steel.
[0049] In this embodiment, both the still lid 200 and the still 100 are made of stainless steel. Stainless steel offers excellent corrosion resistance, allowing the still lid 200 and the still 100 to maintain material stability in high-temperature and high-humidity distillation environments, thus avoiding the corrosion and degradation problems that may occur with traditional materials during long-term use. Furthermore, stainless steel has high mechanical strength, enabling it to withstand internal pressure changes during distillation and ensuring the structural integrity of the still lid 200 and the still 100. The thermal conductivity of stainless steel contributes to the uniform distribution of heat during distillation, thereby improving distillation efficiency. Simultaneously, the smooth surface of stainless steel facilitates cleaning and maintenance, reducing the possibility of impurity residue and further improving the hygiene of the distillation process.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
