Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and more specifically, to a brewing still. Background Technology

[0002] With the popularization of grain steaming equipment for brewing, large-scale hanging stills for brewing are widely used in grain steaming operations of 500 jin (250 catties) or more. Taking the common Manzhonghua 900-type hanging still as an example, this equipment has a diameter of 190cm and adopts a welded lifting ring design, requiring the use of an electric hoist and lifting frame for handling. Its bottom center has a support beam structure, with the still grates installed on both sides of the support beam via a rotating connection and secured with a pin locking mechanism. However, this traditional design has significant drawbacks: First, the welded lifting ring structure protrudes from the still body surface, easily causing mechanical interference with the still lid during the steaming process; second, when the beam needs to be removed after steaming, the operator must contact the pin located at the bottom of the hot still body, posing a serious risk of burns. Utility Model Content

[0005] Furthermore, the bottom of the support rod is provided with a second hinge seat, on which a fixed shaft is installed, and a semi-circular grate is rotatably connected.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: In existing technologies, traditional brewing stills use a welded external lifting ring structure. The lifting ring protrudes from the outer wall of the still, easily interfering with the steaming lid and affecting the sealing effect. The bottom grate locking mechanism is usually located below the support beam, requiring operators to handle the bottom pin in a high-temperature environment, posing a risk of burns. For example, the Manzhonghua 900 model still uses a bottom pin locking method; when disassembling the grate after steaming, operators must approach the high-temperature area, posing a high safety risk.

[0015] To address the aforementioned issues, the spatial interference problem caused by the traditional external lifting ring structure was found to be eliminated by retracting the lifting ring into the inner wall of the cylinder. To mitigate the operational risks associated with the bottom pin, the locking mechanism was moved from the bottom to the side wall, avoiding high-temperature contact through lateral operation. Furthermore, the insufficient closure stability of the grate was identified, which can be addressed by enhancing the seal through the synergistic effect of a tapered guide structure and material pressure.

[0016] like Figures 1-5 As shown, a brewing still includes a cylindrical body 100. Multiple first hinge seats 201 are arranged in a ring on the inner wall of the cylindrical body. An upper rotating shaft 202 is provided on each first hinge seat, and a lifting ring 203 is rotatably connected to the upper rotating shaft. A horizontally arranged support rod 501 is provided on the inner wall of the bottom of the cylindrical body. Two semi-circular grates 504 are rotatably connected to the bottom of the support rod. A limiting ring 506 is provided on each semi-circular grate. A rotating mechanism is provided on the inner wall of the cylindrical body, which can be engaged within the limiting ring to restrict the rotation of the semi-circular grates around the support rod.

[0017] The first hinge seat refers to the mounting base fixed to the inner wall of the cylinder, which can be installed on the inner wall of the cylinder by welding or bolting, and is used to support the hinge structure of the lifting ring. The support rod is a rigid component horizontally set at the bottom of the cylinder, which can be made of I-beams or rectangular steel pipes, and is used to support the rotating shaft of the semi-circular grate. The semi-circular grate is an arc-shaped filter component that can rotate around the axis of the support rod, which can be made of perforated stainless steel plate, and forms a complete circular filter surface when closed. The rotating mechanism is a mechanical locking device set on the side wall of the cylinder, which can be a rotating shaft structure with a plug rod, and the grate position is locked by the engagement of the plug rod and the limiting ring.

[0018] Specifically, the lifting ring is integrated into the inner wall of the cylinder via a hinged seat. When not in use, it can be rotated and retracted to a position flush with the inner wall of the cylinder, preventing interference with external components. The semi-circular grate at the bottom of the support rod rotates and opens / closes via a fixed shaft. When the insert rod in the rotating mechanism is inserted into the limiting ring, the grate is locked in a horizontally closed state. The conical guide hopper forms an inclined guide surface within the cylinder. When material is filled, the weight of the material forces the edge of the guide hopper to press tightly against the grate surface, forming an auxiliary seal. The rotating mechanism is located in the middle of the cylinder's side wall. Operators can control the engagement state of the insert rod and the limiting ring by rotating the handle, without needing to contact the high-temperature area.

[0019] Compared to existing technologies, the welded lifting ring of the Manzhonghua 900-type steamer has been replaced with a retractable built-in hinged structure, eliminating interference from protruding parts on the steaming lid. The bottom pin locking method has been replaced by a side-wall rotating rod, shifting the operating position from the high-temperature bottom to a safer side area. The semi-circular grate achieves double locking through the cooperation of the limiting ring and the rod, and combined with the material pressure on the conical guide hopper, improves the sealing reliability in the closed state.

[0020] Through the above technical solution, this application avoids the spatial interference problem caused by the external placement of the lifting ring, eliminates the safety hazard of operators coming into contact with the high-temperature bottom, and at the same time, through the synergistic effect of material pressure and mechanical locking, ensures the stable closure of the grate during the grain steaming process.

[0021] In at least one embodiment, the bottom of the support rod is provided with a second hinge seat 502, a fixed shaft 503 is installed on the second hinge seat, and a semi-circular grate is rotatably connected to the fixed shaft.

[0022] The second hinge seat is a mounting base fixedly connected to the bottom of the support rod, which can be achieved by welding or bolting, providing a stable rotation fulcrum for the semi-circular grate. The fixed shaft is a rigid connecting component passing through the second hinge seat, which can be made of stainless steel and fixed by a snap ring or nut at the shaft end, forming the rotation axis of the semi-circular grate. The semi-circular grate is an arc-shaped grate plate covering the bottom area of ​​the cylinder, which can be made of perforated steel plate, with its edge rotatably connected to the fixed shaft via bearings or bushings. Furthermore, the two semicircular grates can seal the bottom of the cylinder after rotating to a horizontal position, and the semicircular grates are provided with several through holes 505.

[0023] The semi-circular grate refers to two symmetrically arranged arc-shaped plate structures, which can be formed by stamping 3-5mm thick stainless steel plates. Its arc radius matches the inner diameter of the cylinder, and its opening and closing function is achieved through rotation. The through holes refer to the holes penetrating the surface of the semi-circular grate, which can be achieved by arranging an array of circular holes with a diameter of 3-8mm. The spacing between the holes is controlled within the range of 20-30mm to ensure steam throughput.

[0024] In at least one embodiment, the rotating mechanism includes a rotating rod 302, a rotating sleeve 301 is provided on the inner wall of the cylinder, a rotating rod is rotatably connected inside the rotating sleeve, an upper limit plate 304 and a lower limit plate 305 are provided on the rotating rod, the upper limit plate and the lower limit plate are respectively located on both sides of the rotating sleeve, a handle 303 is provided at the top of the rotating rod, and a rotating insertion rod 306 is provided at the bottom of the rotating rod.

[0025] The rotating sleeve is an annular support component fixed to the inner wall of the cylinder. It can be made of stainless steel casting welded to the cylinder body, providing radial support for the rotating rod and constraining its rotation trajectory. The upper and lower limit plates are annular bosses fixed to the rotating rod, which can be flanged and bolted to the rotating rod, limiting the axial displacement of the rotating rod within the rotating sleeve. The rotating insert is an L-shaped locking component located at the bottom of the rotating rod, which can be a bent metal rod integrally formed with the rotating rod, used to mechanically engage with the limit ring through rotational movement. Specifically, the rotating sleeve serves as the supporting base for the rotating rod, allowing it to rotate only around its own axis. When the operator rotates the rotating rod via the top handle, the rotating insert rod rotates synchronously with the rotating rod to the bottom of the limiting ring. Mechanical interference is created between the insert rod and the limiting ring, preventing the semi-circular grate from rotating around the supporting rod. Upper and lower limiting plates are located on the upper and lower sides of the rotating sleeve, respectively, axially limiting the rotation to prevent longitudinal displacement of the rotating rod during rotation and ensuring precise alignment of the insert rod and the limiting ring. Compared to existing technologies, traditional bottom locking mechanisms require manual operation by personnel in high-temperature areas, posing a risk of burns. This solution, however, uses a top handle to control the rotating rod, allowing the locking operation to be completed entirely from the top of the vessel. This application achieves safe operation of the bottom locking mechanism in the brewing still, eliminating the risk of operators coming into contact with high-temperature components.

[0026] Furthermore, the rotation of the rotating rod enables the rotating insert rod to rotate to the bottom of the limiting ring, thereby restricting the semi-circular grate from rotating around the support rod.

[0027] Furthermore, a conical guide hopper 400 is formed on the inner wall of the cylinder, and a positioning hole 401 for accommodating the insertion of a rotating rod is formed on the conical guide hopper.

[0028] The conical guide hopper refers to the inclined conical surface structure formed on the inner wall. This can be achieved by stamping and integrally machining the hopper with the cylinder body. The conical angle is controlled within the range of 45° to 60°, ensuring smooth grain flow while providing effective compression. During grain filling, this structure alters the contact state between the guide hopper edge and the semi-circular grate through gravity compression, creating an auxiliary locking effect. The positioning hole is a through-hole created on the conical guide hopper. It can be formed using laser cutting, with a diameter slightly larger than the diameter of the rotating rod, for example, 1.05 times the diameter of the rotating rod. This ensures smooth insertion of the rotating rod while limiting radial offset. This hole position corresponds to the movement trajectory of the rotating rod, ensuring the accuracy of the insertion action.

[0029] Specifically, when the rotating rod is driven to rotate by the handle, the rotating insert rod moves along the axis of the positioning hole in the conical guide hopper. After the cylinder is filled with grain, the gravity of the grain acts on the inclined conical surface of the conical guide hopper, forcing the edge of the guide hopper to undergo elastic deformation and press tightly against the surface of the semi-circular grate, forming additional frictional locking force. The operator only needs to rotate the handle at the top of the cylinder to accurately insert the rotating insert rod into the bottom of the limiting ring, without having to operate near the hot bottom of the cylinder.

[0030] Furthermore, when the cylinder is filled with grain, the grain can compress the edge of the conical guide bucket, causing the edge of the conical guide bucket to abut against the surface of the semi-circular grate.

[0031] Specifically, after the grain is loaded into the cylinder, its gravity acts on the inclined wall of the conical guide hopper. The radial pressure generated by the grain accumulation forces the edge of the conical guide hopper to undergo elastic deformation downwards, causing the edge of the guide hopper to fit tightly against the surface of the semi-circular grate. This fitting action forms a continuous contact area, which on the one hand compensates for gaps in the semi-circular grate caused by processing errors or thermal deformation, and on the other hand maintains the contact state through continuous pressure, preventing steam from leaking from the contact surface.

[0032] In at least one embodiment, an extension ring 101 is formed at the top of the cylinder, and a lower ring 102 is formed at the bottom edge of the extension ring for sealing with the outer steamer.

[0033] The outer ring refers to the annular flange structure that extends horizontally outward from the top of the cylinder. It can be achieved by bending a metal sheet integrally formed with the cylinder. This structure expands the planar coverage area of ​​the top of the cylinder to form a sealing contact surface. The lower ring refers to the annular protrusion extending vertically downward from the bottom of the outer edge of the outer ring. It can be achieved by welding or stamping. This annular recessed structure can form a nested fit with the corresponding flange at the top of the outer casing. Specifically, the planar expansion design of the outer ring increases the contact area between the top of the cylinder and the outer cover, forming the first planar sealing path. The lower ring extends downwards from the bottom of the outer ring, forming a vertical snap-fit ​​with the annular groove on the edge of the outer cover, creating the second three-dimensional sealing path. When the outer cover is closed, the plane of the outer ring fits against the end face of the outer cover, and the annular protrusion of the lower ring embeds into the groove of the outer cover, preventing high-temperature steam leakage through the dual sealing paths.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
