Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and in particular to a still for distilling alcohol. Background Technology

[0002] In existing distillation equipment, the still body, bottom pot, and lid are typically designed separately. This design facilitates the individual handling of the still body using forklifts or similar equipment to coordinate with automated feeding equipment for filling with mash. It also streamlines the subsequent unloading of mash after handling. To ensure a tight seal, the lid and still body are generally connected by a detachable, sealed connection, while the still body maintains a sealed contact with the bottom pot, allowing steam generated in the bottom pot to smoothly enter the still body for distillation.

[0003] For example, Chinese invention application CN110656017A discloses an energy-saving still for distilling alcohol, including a bottom pot, a still body, and a still lid. The top of the still body has a first annular groove, and the lower edge of the still lid extends downwards to form a first retaining rim. The first retaining rim engages within the first groove, and a sealing device is provided within the first retaining rim to achieve an effective seal between the still body and the still lid. The upper edge of the bottom pot has a second groove, and the lower edge of the still body extends downwards to form a second retaining rim. The second retaining rim also engages within the second groove, and a sealing device is provided within the second retaining rim to prevent steam from escaping from the connection between the bottom pot and the still. In this design, the second groove serves both guiding and positioning functions, helping the still body to accurately align with the steam outlet located in the bottom pot.

[0004] However, in practical applications, it has been found that the still is frequently moved and placed on the ground. Under the weight of the fermented grains inside, the still is prone to compression deformation, causing its bottom shape (such as the original circle) to become irregular. In addition, the still is exposed to a high-temperature steam environment for a long time, inevitably resulting in thermal expansion and contraction deformation. These accumulated deformations cause the bottom shape of the still to not precisely match the second groove of the bottom pot, making placement difficult. If the size of the second groove is designed to be too large to accommodate deformation, it will weaken its key limiting and guiding functions, creating a design contradiction. Utility Model Content

[0005] To address the technical problem that the grooves in existing stills easily fail to limit and guide the still body after deformation, this utility model provides a still device for distilling alcohol with a dynamically adjustable guiding and limiting structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A still for distilling alcohol includes a lid, a body, and a bottom pot. The lid and body are in sealed contact. The top surface of the bottom pot has a steam outlet. The bottom of the still is covered by the steam outlet. The body and bottom pot are in sealed contact.

[0008] The top surface of the bottom pot is equipped with multiple sets of guide structures, which are arranged in a ring at intervals around the center line of the steam outlet.

[0009] The single-unit guide structure includes a base, a guide member, and a screw. The base is fixedly mounted on the top surface of the bottom pot. The guide member has a plane that contacts the top surface of the base and can slide radially along the bottom pot. A screw sleeve is fixedly mounted on one side of the top surface of the base. The screw is threadedly connected to the screw sleeve. A support is provided on the guide member. One end of the screw is rotatably connected to the support on the same axis, so that the rotational motion of the screw is converted into the linear motion of the guide member along the radial direction of the bottom pot. The guide member has a guide surface that extends radially outward from the center of the steam outlet along the bottom pot and is inclined upward.

[0010] Furthermore, it includes 6 sets of guiding structures, which are arranged at equal intervals in a ring around the center line of the steam outlet.

[0011] Furthermore, the linear movement range of the guide component along the radial direction of the bottom pot is 0–50 mm.

[0012] Furthermore, the lower edge of the steamer cover is provided with an annular first groove, and a first sealing ring matching the first groove is provided in the first groove. The top and bottom of the first sealing ring are both wavy, the bottom of the first sealing ring extends beyond the edge of the first groove, and the part of the first sealing ring extending beyond the edge of the first groove is pressed into contact with the top surface of the steamer body.

[0013] Furthermore, a first retaining strip is fixedly disposed within the first groove, and a first retaining groove matching the first retaining strip is disposed on the first sealing ring.

[0014] Furthermore, the lower edge of the steamer body is provided with an annular second groove, and a second sealing ring matching the second groove is provided in the second groove. The top and bottom of the second sealing ring are both wavy, and the bottom of the second sealing ring extends beyond the edge of the second groove. The part of the second sealing ring that extends beyond the edge of the second groove is pressed into contact with the top surface of the bottom pot.

[0015] Furthermore, a second retaining strip is fixedly installed in the second groove, and a second retaining groove matching the second retaining strip is provided on the second sealing ring.

[0016] Furthermore, four retaining rings are fixedly installed on the outer surface of the steamer lid. The four retaining rings are distributed in a ring around the central axis of the steamer lid. Four buckles are connected to the outer surface of the steamer lid for engaging with the retaining rings. Each buckle corresponds to a single retaining ring.

[0017] The beneficial effects of this utility model are:

[0018] By innovatively replacing the fixed-size and fixed-shape grooves on the bottom pot with multiple sets of guide structures that can be independently adjusted radially along the bottom pot, the two major problems faced by traditional grooves—"limiting guide failure" and "size compatibility contradiction"—are effectively solved when the steamer body deforms (out of roundness) due to gravity compression and thermal expansion and contraction, and when it needs to be adapted to steamers of different diameters.

[0019] To address the issue of steamer body deformation and out-of-roundness: grooves of fixed size and shape cannot adapt to the irregular contours of the bottom of the steamer body after deformation, resulting in difficulty in fastening or poor sealing; however, the multiple sets of independent guide members that can slide radially along the bottom of the pot, along with their upward-sloping guide surfaces, allow operators to precisely adjust the position of each guide member by rotating the screw according to the actual deformation (out-of-roundness) of the steamer body, so that the "positioning ring" formed by it dynamically fits the edge contour of the deformed steamer body, ensuring that the steamer body can still accurately cover the steam outlet in the deformed state and maintain an effective seal.

[0020] Addressing the issue of adapting to steamers of different diameters: Fixed-size grooves can only fit steamers of a specific diameter, requiring replacement of the bottom pot or groove when changing the steamer. This application, however, utilizes a screw-driven guide component that slides radially along the bottom pot on the base. This allows the diameter of the "positioning ring," formed by the guide surfaces of multiple guide components, to be continuously adjusted within the screw's stroke range. This enables the guide structure on the same bottom pot to adapt to various steamers within a certain diameter range. Precise positioning and guidance can be achieved simply by adjusting the position of each guide component, significantly improving the equipment's versatility and flexibility.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0029] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figures 1 to 6 As shown, this utility model provides a still for distilling alcohol.

[0032] like Figure 1 and Figure 2 As shown, to solve the technical problem that the limiting and guiding function of the second groove 14 is prone to failure after the existing still body 2 is deformed, this embodiment provides a still device for distilling wine with dynamically adjustable guiding and limiting structures, including a still cover 1, a still body 2 and a bottom pot 3. The still cover 1 is in sealed contact with the still body 2, the top surface of the bottom pot 3 has a steam outlet, and the bottom of the still body 2 is covered over the steam outlet. The still body 2 and the bottom pot 3 are in sealed contact. For the sealed contact mentioned in this embodiment, a water seal groove can be opened on the still body 2, the still cover 1 is fastened in the water seal groove and water is injected to achieve a seal. Alternatively, a rubber or silicone sealing ring can be set at the contact point between the still cover 1 and the still body 2 to achieve a seal, or other existing sealing methods can be selected. Similarly, the seal between the still body 2 and the bottom pot 3 can also be set as above. The choice of sealing method is not particularly limited here, as long as it can achieve a seal between the two.

[0033] It is known that the still lid 1 should be provided with a distillation outlet for discharging alcohol vapor from the still body 2;

[0034] like Figure 1 As shown, Figure 1 The steamer body 2 in the figure is a half-sectional view, so only the internal structure of one side of the steamer body 2 is shown;

[0035] The top surface of the bottom pot 3 is provided with multiple sets of guide structures. The multiple sets of guide structures are arranged in a ring at intervals around the center line of the steam outlet. For multiple sets, it means three or more sets. The multiple sets of guide structures are arranged in a ring at intervals around the center line of the steam outlet. They can be arranged at equal intervals or non-equal intervals. There is no special limitation here, as long as they can be adapted to the bottom of the steamer body 2.

[0036] The single-unit guide structure includes a base 4, a guide member 5, and a screw 6. The base 4 is fixedly mounted on the top surface of the bottom pot 3, preferably by welding, but can also be fixed by bolts or snap-fit. The guide member 5 has a plane that contacts the top surface of the base 4 and can slide radially along the bottom pot 3. This plane is used to limit the rotation of the guide member 5. A threaded sleeve 7 is fixedly mounted on one side of the top surface of the base 4, and the screw 6 is threadedly connected to the threaded sleeve 7. A support 8 is provided on the guide member 5, and one end of the screw 6 is coaxially rotatably connected to the support 8, so that the rotational motion of the screw 6 is converted into the movement of the guide member 5 along the bottom pot. 3. The radial linear motion, driven by the screw 6 manually or electrically to rotate forward and reverse, can dynamically adjust the guide 5 to slide radially along the base 4, so that the "positioning ring" formed by multiple sets of guide structures dynamically fits the edge contour of the deformed steamer body 2 or adapts to the steamer body 2 of different sizes, ensuring that the steamer body 2 can still be accurately covered above the steam outlet in the deformed state and maintain effective sealing. In order to facilitate the guide 5 to guide and cooperate with the steamer body 2, the guide 5 has a guide surface 9 that is radially outward from the center of the steam outlet along the bottom pot 3 and inclined upward.

[0037] Preferably, the guide structure is configured with 6 sets, arranged equidistantly in a ring around the center line of the steam outlet. Using 6 sets avoids the problem of insufficient sets, which might lead to difficulty in effectively fitting irregular deformations and cause wobbling at the guide gaps. Conversely, too many sets would significantly increase manufacturing costs and adjustment time. Ultimately, 6 sets of guide structures are chosen to achieve precise positioning of the deformable steamer body 2 and rapid switching between multiple specifications of steamer body 2 at a relatively low manufacturing cost, resolving the irreconcilable contradiction between rigid grooves and deformation requirements in traditional technologies.

[0038] The linear movement range of the guide member 5 along the radial direction of the bottom pot 3 is preferably 0 to 50 mm. Of course, the movement range can be adjusted radially according to the actual working conditions on site. This is related to the outer dimensions of the steamer body 2 of different specifications. The movement range can be adjusted adaptively, for example, 0 to 100 mm or 0 to 150 mm.

[0039] Working Principle: During the distillation process, the still body 2 is first hoisted above the bottom pot 3. Guided by the inclined guide surfaces 9 of the 6 sets of guide structures, the still body 2 gradually descends until its bottom contacts the top surface of the base 4, and the bottom of the still body 2 covers the steam outlet of the bottom pot 3. Then, the lees are filled into the still body 2, and the lid 1 is closed to complete the seal. The bottom pot 3 contains steam at 90℃~12℃. The steam enters the still body 2 through the steam outlet, carrying the alcohol in the lees to evaporate. The alcohol-containing steam is discharged through the distillation outlet at the top of the lid 1 and enters the condensation recovery system through the steam pipe.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, for the sealing between the steamer lid 1 and the steamer body 2, this embodiment selects to provide an annular first groove 10 at the lower edge of the steamer lid 1. A first sealing ring 11 matching the first groove 10 is provided in the first groove 10. The top and bottom of the first sealing ring 11 are both wavy. The first sealing ring 11 should have a certain elasticity. The wavy design improves the deformation capability of the first sealing ring 11. During the sealing process between the steamer lid 1 and the steamer body 2, the deformation capability of the first sealing ring 11 is enhanced. The first sealing ring 11 can fill the gap between the steamer lid 1 and the steamer body 2 well, ensuring that the alcohol vapor does not leak out. The bottom of the first sealing ring 11 extends beyond the edge of the first groove 10. The part of the first sealing ring 11 that extends beyond the edge of the first groove 10 is pressed and contacted with the top surface of the steamer body 2.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a first retaining strip 12 is fixedly disposed within the first groove 10, and a first retaining groove 13 matching the first retaining strip 12 is provided on the first sealing ring 11. The first retaining strip 12 limits and fixes the first sealing ring 11, enhancing the stability of its connection and preventing the first sealing ring 11 from falling out of the first groove 10. Besides the design of this embodiment, the first sealing ring 11 can also be directly embedded in the first groove 10, or glued, or fixed by setting a limiting block. The material of the first sealing ring 11 is silicone rubber or other existing sealing materials.

[0042] like Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, for the sealing between the steamer body 2 and the bottom pot 3, this embodiment selects an annular second groove 14 at the lower edge of the steamer body 2. A second sealing ring 15 matching the second groove 14 is provided within the second groove 14. The top and bottom of the second sealing ring 15 are both wavy. The second sealing ring 15 has the same structure as the first sealing ring 11. The second sealing ring 15 should have a certain elasticity. The wavy design improves the deformation capacity of the second sealing ring 15. During the sealing process between the steamer body 2 and the bottom pot 3, the deformation capacity of the second sealing ring 15 is enhanced, allowing it to effectively fill the gap between the steamer body 2 and the bottom pot 3, ensuring that high-temperature steam does not leak out. The bottom of the second sealing ring 15 extends beyond the edge of the second groove 14, and the portion of the second sealing ring 15 extending beyond the edge of the second groove 14 makes contact with the top surface of the bottom pot 3.

[0043] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, a second retaining strip 16 is fixedly disposed within the second groove 14, and a second retaining groove 17 matching the second retaining strip 16 is provided on the second sealing ring 15. The second retaining strip 16 limits and fixes the second sealing ring 15, enhancing the stability of its connection and preventing the second sealing ring 15 from falling out of the second groove 14. Besides the design of this embodiment, the second sealing ring 15 can also be directly embedded in the second groove 14, or glued, or fixed by setting a limiting block. The material of the second sealing ring 15 is silicone rubber or other existing sealing materials.

[0044] like Figure 1 As shown, to further improve the seal between the steamer lid 1 and the steamer body 2, four retaining rings 18 are fixedly installed on the outer surface of the steamer lid 1. The four retaining rings 18 are distributed in a ring at intervals around the central axis of the steamer lid 1. Four buckles 19 are connected to the outer surface of the steamer body 2 for engaging with the retaining rings 18, with each buckle 19 corresponding to a single retaining ring 18. Due to the gravity of the steamer body 2, the steamer lid 1, and the lees, the sealing contact between the steamer body 2 and the bottom pot 3 is very strong. However, the steamer lid 1 is easily affected by steam, and the sealing contact between the steamer lid 1 and the steamer body 2 is prone to failure. Therefore, the four retaining rings 18 and four buckles 19 are used to engage and strengthen the sealing contact between the steamer lid 1 and the steamer body 2.
