Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a steam jacketed kettle for the production of thick liquor. Background Technology

[0002] With the development of the food industry, the requirements for the production quality and efficiency of alcoholic beverages, especially thick liquor, are constantly increasing. The performance of the steam jacketed kettle directly affects the quality and production cost of thick liquor. A high-efficiency, safe, and easy-to-operate and maintain steam jacketed kettle can improve the automation level of production and the stability of product quality, which is of great significance for promoting the development of the thick liquor industry.

[0003] Traditional steam jacketed kettles typically employ simple fixing methods to connect the inner pot to other components. For example, some use bolts and nuts to secure the inner pot to the lid, which requires tools for installation and disassembly, making the process cumbersome. Others use a snap-fit ​​structure, where the inner pot is connected to the lid by snapping the snaps together. However, the stability of the snap-fit ​​connection may be affected by usage time and frequent opening and closing, and manual snapping is also required.

[0004] Regarding the aforementioned technologies, whether using bolts and nuts or clips, bolt and nut connections are inconvenient to operate and consume time and manpower; clips also require manual engagement, which leads to a significant waste of time and reduced work efficiency. Utility Model Content

[0005] To overcome the above problems, this application provides a steam jacketed kettle for the production of thick liquor.

[0006] The technical solution provided in this application for a steam jacketed kettle for producing thick liquor is as follows: A steam jacketed kettle for producing thick liquor includes a support assembly, a kettle body, a lid assembly, and a stirring assembly. The kettle body includes an outer pot, an inner pot for holding materials, and a heating element for heating the inner pot. The inner pot is connected to the outer pot, and a steam gap is left between the outer wall of the inner pot and the inner wall of the outer pot. The outer pot is connected to the support assembly. One end of the heating element is connected to a steam source, and the other end of the heating element is located in the steam gap. The lid assembly includes a lid plate and a rotating component. The lid plate fits into the opening of the inner pot. The rotating component includes a rotating rod and multiple fastening sources. The rotating rod is located at the top of the lid plate and extends from the middle of the lid plate to its side wall. The rotating rod is connected to the lid plate. The multiple fastening sources are evenly distributed along the circumference of the lid plate on the side of the lid plate near the inner pot. Each fastening source includes an L-shaped rod, one end of which is connected to the lid plate. The inner pot has multiple fixing grooves at its opening for the L-shaped rods to extend into. The inner pot also has an L-shaped groove at the fixing groove, which communicates with the fixing groove. The L-shaped groove and the fixing groove are distributed along the circumference of the inner pot. The lid plate is rotatably connected to the inner pot from the fixing groove to the L-shaped groove side. The stirring assembly includes a rotating component and a stirring component. The rotating component is connected to the cover plate, and the rotating component and the stirring component are connected to stir the material.

[0007] By adopting the above technical solution, when a steam jacketed kettle is required, the support assembly provides stable support for the kettle body. Material is injected into the inner pot, and after injection, the inner pot opening is closed by the cover plate. At this time, the L-shaped rod extends into the fixed groove. Subsequently, rotating the rotating rod drives the cover plate to rotate, causing the L-shaped rod to rotate into the L-shaped groove, thus connecting the cover plate and the inner pot. The heating element located in the steam gap heats the material in the inner pot, ensuring uniform heating. The rotating component, through the rotating rod, drives multiple fastening sources of the L-shaped rod to rotate within the fixed groove and L-shaped groove, achieving a rotating connection between the cover plate and the inner pot, facilitating closing and opening, and improving personnel work efficiency. The rotating component drives the stirring component to stir the material, ensuring uniform mixing and improving the efficiency and quality of thick liquor production.

[0008] In one specific implementation, the fastening source further includes an abutment block located at the opening of the L-shaped rod. The abutment block is elastically slidably connected to the end of the L-shaped rod away from the cover plate. The side of the abutment block near the L-shaped groove is provided as an inclined surface, which is inclined from the side of the L-shaped groove to the fixed groove toward the side away from the L-shaped rod.

[0009] By adopting the above technical solution, the abutment block can slide elastically. With its inclined surface design, when connecting the cover plate to the inner pot, the abutment block can slide towards the side closer to the L-shaped rod after contacting the inner pot until the L-shaped rod is located in the L-shaped groove, and the abutment block abuts against the inner pot, which can firmly fix the cover plate and the inner pot. The inclined surface design of the abutment block allows the abutment block to automatically realize the elastic sliding and abutment functions during the rotation of the rotating rod, without the need for additional manual operation. This avoids the problems of cumbersome operation and connection stability of traditional connection methods, and improves the convenience and stability of pot lid closing.

[0010] In one specific implementation, the stirring assembly further includes a lifting component and a snap-fit ​​component. The lifting component is connected to the support assembly. The rotating component includes a rotating rod and a rotating source. The rotating rod is perpendicular to the cover plate and passes through the cover plate before being connected to the stirring component. The rotating rod is rotatably connected to the cover plate and passes through the rotating rod. The lifting component is connected to the rotating source to drive the rotating source to move towards or away from the inner pot. The rotating source is connected to the rotating rod to drive the rotating rod to rotate. The rotating rod has a locking groove along its length near the rotating rod. The locking component includes a locking block and a locking spring. The locking block is located in the locking groove and slides back and forth along the direction of the locking groove. The rotating rod has a slot for the locking block to be inserted into on the side near the locking groove. The locking spring is located in the locking groove and on the side of the locking block away from the cover plate. The direction of the locking spring is the same as the direction of the locking groove. One end of the locking spring is connected to the rotating rod, and the other end is connected to the locking block. The locking spring does not deform, the locking block is not inserted into the slot, and the locking block is detachably connected to the rotating rod.

[0011] By adopting the above technical solution, the lifting component connects the support assembly and the rotating source, which can drive the rotating source closer to or further away from the inner pot, allowing for flexible adjustment of the stirring position. The rotating source drives the rotating rod to rotate, causing the stirring component to stir the material. The locking block and the rotating rod are detachably connected through locking grooves, slots, and locking springs, allowing the rotating rod to rotate synchronously with or separate from the rotating rod as needed, driving the cover plate to rotate or allowing the rotating rod and the rotating rod to rotate independently. When the cover plate needs to be rotated, the locking block fixes the rotating rod and the rotating rod, and the rotation of the rotating rod can drive the cover plate to rotate. When the cover plate does not need to be rotated, the locking block is released, and the rotating rod can rotate independently for stirring, enhancing the flexibility and applicability of the steam jacketed kettle operation.

[0012] In one specific implementation, the stirring component includes two flat paddles, two oblique blade paddles, and one arc-shaped paddle. The flat paddles, oblique blade paddles, and arc-shaped paddles are all located at the end of the rotating rod near the bottom of the cover plate. The flat paddles, oblique blade paddles, and arc-shaped paddles are distributed sequentially and spaced away from the cover plate along the length of the rotating rod. The two flat paddles are evenly distributed around the circumference of the rotating rod and are perpendicularly connected to the rotating rod. The two oblique blade paddles are evenly distributed around the circumference of the rotating rod and are perpendicularly connected to the rotating rod. The arc of the arc-shaped paddle is consistent with the arc of the inner pot, and the opening direction of the arc-shaped paddle is consistent with the opening direction of the inner pot. The bottom of the rotating rod is connected to the middle of the arc-shaped paddle. A silicone scraper strip is fixed to the side of the arc-shaped paddle near the inner wall of the inner pot, and the silicone scraper strip is in close contact with the inner wall of the inner pot.

[0013] By adopting the above technical solution, the multi-layered blade design of the mixing component, namely the horizontal blade, the inclined blade, and the arc-shaped blade, are distributed at intervals along the length of the rotating rod, which can stir the material at different heights, making the material more uniformly mixed; the two horizontal blades and the two inclined blades are evenly distributed around the circumference of the rotating rod, which can expand the stirring range and improve the stirring efficiency; the arc-shaped blade has the same curvature as the inner pot and the same opening direction, which can better fit the bottom of the inner pot for stirring; the silicone scraper strip on the arc-shaped blade is in close contact with the inner wall of the inner pot, which can scrape off the material adhering to the inner wall of the inner pot, avoiding the problem of "overheating of the pot wall and sluggish heating of the material center".

[0014] In one specific implementation, the stirring assembly further includes a scraping component, which includes a scraping rod and a wall scraping strip. The scraping rod is located at the bottom of the cover plate and extends from the middle of the cover plate to the side wall of the cover plate. One end of the scraping rod near the middle of the cover plate is connected to the rotating rod, and the other end is connected to the side wall of the inner pot. The wall scraping strip is fixed to the scraping rod near the side of the cover plate and contacts the bottom of the cover plate.

[0015] By adopting the above technical solutions, the scraping rod and scraping strip can clean the bottom of the cover plate, prevent material waste, and improve the efficiency and quality of thick liquor production.

[0016] In one specific implementation, the lid assembly further includes a sealing element, a connecting ring is coaxially connected to the side of the lid near the inner pot, the inner pot has an annular groove at its opening that fits with the connecting ring, the sealing element is a sealing gasket, the sealing gasket is connected to the connecting ring, and the sealing gasket can seal the connection between the inner pot and the lid.

[0017] By adopting the above technical solution, a sealing gasket is set in the lid assembly of the steam jacketed kettle, which is connected to the connecting ring of the lid plate and fits into the annular groove at the opening of the inner pot. This seals the connection between the inner pot and the lid plate, preventing the loss of materials and heat in the inner pot, improving the sealing performance of the kettle, and helping to improve the efficiency and quality of thick liquor production.

[0018] In one specific implementation, the latching component further includes a blocking block, which is elastically slidably connected to the side of the latching block away from the rotating rod. The blocking block is located near the end of the latching block away from the latching spring. The side of the blocking block away from the latching spring is set as an inclined surface. The inclined surface is set from the rotating rod to the latching block towards the side away from the latching block. The latching block is inserted into the slot, and the blocking block is latched with the rotating rod.

[0019] By adopting the above technical solution, after the snap-fit ​​block is inserted into the slot, the blocking block snaps into the rotating rod, which can firmly fix the rotating rod and the rotating rod, so that the rotating rod can rotate synchronously with the rotating rod and drive the cover plate to rotate; when the rotating rod and the rotating rod do not need to be fixed, pressing the blocking block can separate the snap-fit ​​block from the slot, realizing the flexible connection and separation of the two.

[0020] In one specific implementation, the bottom of the outer pot is connected to a connecting pipe for condensate drainage. The connecting pipe is oriented in the same direction as the axis of the outer pot, and is connected to a steam gap. A valve is connected to the connecting pipe.

[0021] By adopting the above technical solution, the connecting pipe at the bottom of the outer pot can discharge the condensate in the steam gap, avoiding the accumulation of condensate that affects the steam heating effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed steam jacketed kettle for thick liquor production features a heating element located in the steam gap that heats the material in the inner pot, ensuring uniform heating. A rotating component drives multiple L-shaped rods with fastening sources to rotate within fixed grooves and L-shaped slots, achieving a rotating connection between the lid and the inner pot. This facilitates closing and opening, improving worker efficiency. The rotating component also drives a stirring component to agitate the material, ensuring uniform mixing and improving the efficiency and quality of thick liquor production.

[0023] 2. The designed steam jacketed kettle for thick liquor production allows the abutment block to slide elastically. Combined with its inclined surface design, when connecting the lid and the inner pot, the abutment block can slide towards the side closer to the L-shaped rod after contacting the inner pot until the L-shaped rod is located in the L-shaped groove, and the abutment block abuts against the inner pot. This can firmly fix the lid and the inner pot, avoiding the problems of cumbersome operation and affected connection stability of traditional connection methods, and improving the convenience and stability of the lid and the pot.

[0024] 3. The designed steam jacketed kettle for thick liquor production features scraper rods and wall scraper strips that can clean the bottom of the lid, preventing material waste and improving the efficiency and quality of thick liquor production. Attached Figure Description

The sealing element 32 is a sealing gasket with a U-shaped longitudinal section. The sealing gasket fits into the connecting ring 311 and is fixedly bonded to the connecting ring 311. When the connecting ring 311 is located in the annular groove 221, the sealing gasket can seal the connection between the inner pot 22 and the lid plate 31, preventing the material and heat in the inner pot 22 from being lost.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The rotating component 33 includes a rotating rod 331 and multiple fastening sources 332. The rotating rod 331 is located on the top of the cover plate 31 and is arranged parallel to the cover plate 31. The rotating rod 331 extends from the middle of the cover plate 31 to the side wall of the cover plate 31, and one end of the rotating rod 331 near the side wall of the cover plate 31 is welded to the cover plate 31.

The rotating source 422 is a rotating motor. The rotating motor is located at the top of the lifting plate 412. The housing of the rotating motor is fixedly connected to the lifting plate 412 by screws. The output shaft of the rotating motor is coaxially fixedly connected to the rotating rod 421 by a coupling. The rotating motor drives the rotating rod 421 to rotate.

[0046] Reference Figure 7 , Figure 8 and Figure 9A rotating rod 421 passes through one end of a rotating rod 331 near the middle of the cover plate 31. A locking groove 4211 is provided on the rotating rod 421 near the rotating rod 331. The locking groove 4211 is provided along the length of the rotating rod 421. The locking component 43 includes a locking block 431, a locking spring 432, and a blocking block 433. The locking block 431 is located in the locking groove 4211 and slides back and forth along the setting direction of the locking groove 4211. A card supply is provided on the side of the rotating rod 331 near the locking groove 4211. The engaging block 431 is inserted into the slot 3311, and the engaging spring 432 is located within the engaging groove 4211. The engaging spring 432 is located on the side of the engaging block 431 closer to the lifting plate 412. The setting direction of the engaging spring 432 is consistent with the setting direction of the engaging groove 4211. One end of the engaging spring 432 is welded to the rotating rod 421, and the other end is welded to the engaging block 431. Under normal conditions, that is, the engaging spring 432 does not deform, the engaging block 431 is not inserted into the slot 3311, and the blocking block 433 is located within the engaging block 431. On the side away from the rotating rod 421, and with the blocking block 433 close to the end of the locking block 431 away from the locking spring 432, the blocking block 433 and the locking block 431 are slidably connected. The side of the blocking block 433 away from the locking spring 432 is set as an inclined surface. The inclined surface is set upward from the rotating rod 331 to the locking block 431 towards the side away from the locking block 431. When it is necessary to fix the rotating rod 331 and the rotating rod 421, that is, when the rotating rod 331 rotates synchronously with the rotating rod 421, it can drive the cover plate 31 to rotate and lock. When block 431 is inserted into slot 3311, the blocking block 433 slides towards the side closer to the snap-fit ​​block 431 until the blocking block 433 passes through slot 3311, so that the blocking block 433 snaps into the rotating rod 331, thus fixing the rotating rod 331 and the rotating rod 421. When the rotating rod 331 and the rotating rod 421 do not need to be fixed, the rotating rod 421 is rotatably connected to the rotating rod 331. When the person presses the blocking block 433, the snap-fit ​​spring 432 returns to its original deformation, thus separating the snap-fit ​​block 431 from the slot 3311.

[0047] Reference Figure 7The stirring component 44 includes two flat impellers 441, two oblique impellers 442, one arc-shaped impeller 443, and two connecting rods 444. The flat impellers 441, oblique impellers 442, and arc-shaped impellers 443 are all located at the end of the rotating rod 421 near the bottom of the cover plate 31. The flat impellers 441, oblique impellers 442, and arc-shaped impellers 443 are distributed alternately along the length of the rotating rod 421 towards the side away from the cover plate 31. The two flat impellers 441 are evenly distributed around the circumference of the rotating rod 421. The horizontal paddle 441 is perpendicular to the rotating rod 421, with one end welded to the rotating rod 421. The horizontal paddle 441 can agitate the surface material. Two oblique blade paddles 442 are evenly distributed around the rotating rod 421, and are perpendicular to the rotating rod 421. One end of the oblique blade paddle 442 is fixedly connected to the rotating rod 421 by screws. The oblique blade paddle 442 can stir the material in the middle. The arc-shaped paddle 443 has the same curvature as the inner pot 22. The opening direction of the 43 is consistent with the opening direction of the inner pot 22. The bottom of the rotating rod 421 is fixedly connected to the middle of the arc-shaped paddle 443 by screws. The arc-shaped paddle 443 can stir the material at the bottom. Two connecting rods 444 are evenly distributed around the circumference of the rotating rod 421. The connecting rods 444 are inclined from the side of the rotating rod 421 to the side away from the rotating rod 421. One end of the connecting rod 444 is fixedly connected to the rotating rod 421 by screws, and the other end is fixedly connected to the arc-shaped paddle 443 by screws. This can enhance the stability of the arc-shaped paddle 443 and facilitate the stirring of the material. The stirring of the material is achieved through multiple layers of paddle blades. A silicone scraper strip 4431 is fixedly bonded to the side of the arc-shaped paddle 443 near the inner wall of the inner pot 22. The silicone scraper strip 4431 is in close contact with the inner wall of the inner pot 22. During the rotation of the arc-shaped paddle 443, it scrapes the inner wall of the inner pot 22 to avoid the problem of "overheating of the pot wall and sluggish material center".

[0048] Reference Figure 7 and Figure 10 The stirring assembly 4 also includes a scraper 45, which includes a scraper rod 451 and a wall scraper 452. The scraper rod 451 is located at the bottom of the cover plate 31 and is arranged parallel to the cover plate 31. The scraper rod 451 extends from the middle of the cover plate 31 to the side wall of the cover plate 31. One end of the scraper rod 451 near the middle of the cover plate 31 is welded to the rotating rod 421, and the other end contacts the inner wall of the inner pot 22. The scraper rod 451 rotates synchronously with the rotating rod 421. The wall scraper 452 is fixedly bonded to the side of the scraper rod 451 near the cover plate 31 and contacts the bottom of the cover plate 31. When the material is being stirred, some material may adhere to the bottom of the cover plate 31. By setting the scraper rod 451 and the wall scraper 452, the cover plate 31 can be cleaned to prevent material waste.

[0049] The implementation principle of a steam jacketed kettle for producing thick liquor according to an embodiment of this application is as follows: The steam jacketed kettle is provided with stable support by the support assembly 1. The rotating component 42 of the kettle body 2 can tilt the outer pot 21 to facilitate cleaning of the inner pot 22. The heating component 24 can ensure that the inner pot 22 is heated evenly. The lid assembly 3 ensures the sealing of the kettle body 2, reducing heat and material loss. The multi-layer blade design of the stirring assembly 4 can fully stir the materials, making the materials mixed evenly, thus improving the efficiency and quality of thick liquor production.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
