Description

Technical Field

[0001] This utility model relates to the field of bone broth production technology, and in particular to a bone broth preparation device that can prevent splashing. Background Technology

[0002] Bone broth, rich in protein, collagen, and minerals, plays an important role in the catering service, pre-prepared food processing, and condiment production industries. Whether it is the standardized soup base preparation of chain restaurants or the large-scale bone broth production of food processing plants, there are extremely high requirements for the efficiency, safety, and quality of bone broth preparation equipment.

[0003] Existing bone broth preparation equipment typically heats the broth using electric heating wires laid flat at the bottom of the equipment. The localized heating characteristics of the electric heating wires easily create high-temperature hot spots in the corresponding areas of the pot bottom. The bone broth evaporates rapidly in the hot spots, generating impact bubbles. When the bubbles rise to the surface and burst, they cause the broth to splash, potentially scalding the operator. At the same time, the splashed broth adheres to the surface of the equipment and the surrounding environment, increasing cleaning difficulty and hygiene risks. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: In the process of preparing bone broth, existing bone broth preparation equipment is prone to the phenomenon of "excessively high local temperature at the bottom of the pot and low temperature of the upper layer of broth", which will cause the broth to splash. Therefore, this invention proposes a bone broth preparation equipment that can prevent splashing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bone broth preparation device that prevents splashing includes a body, an installation cavity at the bottom of the body, a vortex-shaped electric heating wire fixedly installed at the bottom of the installation cavity, a preparation tank at the top of the body, a rotating rod vertically rotating inside the preparation tank, the bottom end of the rotating rod penetrating into the installation cavity and rotatably connected to the bottom of the installation cavity, multiple stirring rods fixedly installed circumferentially on the surface of the rotating rod, a covering assembly for covering the opening of the preparation tank at the top of the body, and a liquid outlet pipe fixedly installed on the side wall at the bottom of the body, with a valve inside the liquid outlet pipe; A drive motor is fixedly installed at the bottom of the machine body. The output shaft of the drive motor passes through the mounting cavity and is fixedly connected to the bottom end of the rotating rod. A cavity is opened inside the rotating rod. Multiple openings corresponding to the ends of multiple stirring rods are opened in a circular shape on the surface of the rotating rod. A rectangular groove is opened at the end of the stirring rod near the opening. Multiple vents are opened in a circular shape on the side wall of the end of the rotating rod located in the mounting cavity.

[0006] Preferably, the cover assembly includes a cover and two vertically fixedly mounted symmetrically on the lower surface of the cover. The side wall of the machine body is symmetrically fixedly mounted with mounting frames. The two vertically mounted rods are respectively vertically slidably inserted into the two mounting frames. The diameter of the cover is larger than the diameter of the machine body. The cover is locked by a locking assembly. The upper surface of the cover has multiple circular openings. Multiple mounting blocks, each covering multiple circular openings, are fixedly mounted on the upper surface of the cover. The top of each mounting block has multiple circumferentially shaped air holes.

[0007] Preferably, the locking assembly includes two spring rods that are horizontally fixed to the side walls of the two vertical rods and two triangular locking blocks that are fixed to the ends of the two spring rods. A stop plate is fixedly installed on the bottom side wall of the mounting frame. The upper surface of the stop plate corresponds to the inclined surface of the locking block, and the length of the stop plate is less than the length of the inclined surface of the locking block. The two spring rods are controlled to retract together by a pulling component.

[0008] Preferably, the pulling component includes two L-shaped plates that are respectively fixedly sleeved on the free ends of two spring rods and two pulling blocks that are respectively fixedly installed on the upper surface of the two L-shaped plates. The upper surface of the cover is provided with a U-shaped groove, and the two L-shaped plates are respectively vertically slidably inserted into the two ends of the U-shaped groove.

[0009] Preferably, two locking plates are fixedly installed on the top side wall of the mounting frame. The length of the locking plates is greater than the length of the locking block, and a locking space for locking the locking block is formed between the two locking plates.

[0010] Preferably, a U-shaped handle is symmetrically fixedly installed on the upper surface of the cover, and the surface of the handle is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The drive motor drives the rotating rod and multiple circumferentially distributed stirring rods to rotate synchronously, which can fully mix the high-temperature broth at the bottom of the preparation tank with the low-temperature broth at the top, quickly breaking the temperature stratification of the broth and avoiding the imbalance of continuous high temperature at the bottom and insufficient temperature at the top. In addition, the stirring process can slow down the speed at which bubbles rise from the bottom of the preparation tank to the liquid surface, reduce the impact force of the bubbles breaking when they reach the liquid surface, and reduce the splashing of broth caused by the bursting of bubbles. At the same time, the circulation formed by stirring can make the bone broth components mix more evenly, avoiding the burning of local raw materials due to overheating, thus meeting the dual requirements of anti-splashing and bone broth quality. 2. Some of the hot air generated by the electric heating wire enters the internal cavity of the rotating rod through multiple vents at the end of the rotating rod, forming a unique hot air circulation system. On the one hand, the hot air in the cavity can "preheat and keep warm" the rotating rod, preventing the temperature difference between the rotating rod and the hot soup from forming due to excessively low temperature. This prevents the soup from condensing on the surface of the rotating rod and dripping to the bottom of the preparation tank, causing local splashing. On the other hand, the hot air enters the rectangular groove of the stirring rod through the rotating rod vents and is dispersed into the soup in various areas of the preparation tank as the stirring rod rotates. This provides uniform heat to the soup, preventing convection turbulence caused by sudden drops in local temperature. At the same time, the slight disturbance of the hot air promotes the internal circulation of the soup, reducing the possibility of bubbles accumulating and forming large bubbles, further enhancing the anti-splashing effect.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-3 A bone broth preparation device designed to prevent splashing includes a body 1, with an installation cavity formed in the bottom of the body 1, such as... Figure 13 As shown, a vortex-shaped electric heating wire 2 is fixedly installed at the bottom of the installation cavity. A preparation tank is opened at the top of the machine body 1. A rotating rod 3 is vertically rotatably installed in the preparation tank. The bottom end of the rotating rod 3 passes through the installation cavity and is rotatably connected to the bottom of the installation cavity. Multiple stirring rods 4 are fixedly installed in a circumferential shape on the surface of the rotating rod 3. A covering assembly for covering the opening of the preparation tank is provided at the top of the machine body 1. A liquid outlet pipe is fixedly installed on the side wall at the bottom of the machine body 1. A valve is provided in the liquid outlet pipe.

[0017] A drive motor 5 is fixedly mounted on the bottom of the machine body 1. The output shaft of the drive motor 5 passes through the mounting cavity and is fixedly connected to the bottom end of the rotating rod 3. Figure 8 As shown, a cavity 7 is formed inside the rotating rod 3, and multiple circumferential openings 8 are formed on the surface of the rotating rod 3, each corresponding to the end position of a plurality of stirring rods 4. A rectangular groove 9 is formed at the end of the stirring rod 4 near the opening 8, as shown in the figure. Figure 11 and Figure 7 As shown, the rotating rod 3 has multiple vents 10 in a circular shape on the side wall of the end of the mounting cavity.

[0018] When preparing bone broth, the raw materials are first put into the preparation tank. Then, the covering component is used to cover the opening of the preparation tank to ensure that the opening is tightly covered, thus initially blocking the path of broth splashing during the subsequent simmering process. After the raw materials are put in and covered, the power supply system of the equipment is started. First, the vortex electric heating wire 2 in the mounting cavity at the bottom of the machine body 1 is turned on. After the electric heating wire 2 is powered on, it begins to heat up. Its vortex structure causes the heat to spread evenly in a ring along the bottom of the preparation tank, avoiding the generation of "local hot spots" in traditional heating methods, and providing a uniform initial heating environment for the bone broth. At the same time, the drive motor 5 fixedly installed at the bottom of the machine body 1 is started. The output shaft of the drive motor 5 passes through the mounting cavity and drives the rotating rod 3 to rotate vertically around its own axis. The rotating rod 3 synchronously drives the multiple stirring rods 4 fixed in a circular shape on the surface to rotate in the preparation tank.

[0019] During the rotation of the stirring rod 4, the high-temperature broth heated by the electric heating wire 2 at the bottom of the preparation tank is fully mixed with the low-temperature broth at the top, breaking the temperature stratification of the broth and preventing localized violent boiling caused by the continuous high temperature at the bottom. During this process, multiple vents 10 on the side wall of the end of the rotating rod 3 in the mounting cavity work simultaneously. Some of the hot air generated by the electric heating wire 2 enters the cavity 7 inside the rotating rod 3 through the vents 10. The hot air flows along the axial direction of the rotating rod 3 in the cavity 7, preheating and keeping the rotating rod 3 warm on one hand, preventing the temperature difference between the rotating rod 3 and the high-temperature broth from forming, which would cause the broth to condense on the surface of the rotating rod 3 and drip to the bottom of the preparation tank, causing localized splashing. On the other hand, the hot air in the cavity 7 enters the rectangular groove 9 opened near the end of the stirring rod 4 near the opening 8 through multiple vents 8 on the surface of the rotating rod 3. With the rotation of the stirring rod 4, it is evenly dispersed into the broth in different areas of the preparation tank, supplementing the broth with heat and further promoting the circulation of the broth through the slight disturbance of the hot air, reducing the possibility of bubbles accumulating and forming large-volume bubbles.

[0020] Throughout the entire process of simmering bone broth, the vortex heating wire 2 continuously provides uniform heat, maintaining the broth in the preparation tank at a stable simmering temperature and preventing the broth from boiling violently due to excessive temperature. The drive motor 5 maintains a stable speed, driving the rotating rod 3 and stirring rod 4 to rotate continuously, ensuring the broth circulation and mixing effect. At the same time, it slows down the speed at which bubbles rise from the bottom of the preparation tank to the liquid surface, reducing the impact force when bubbles burst and minimizing broth splashing. The covering component always tightly covers the opening of the preparation tank, directly blocking any small amount of splashed broth that may occur, preventing it from splashing out of the equipment.

[0021] Once the bone broth is ready, first turn off the drive motor 5 and the electric heating wire 2 to stop stirring and heating. After the temperature of the broth in the preparation tank drops slightly, open the valve in the liquid outlet pipe fixed to the side wall at the bottom of the machine body 1. The prepared bone broth will be discharged at a constant speed through the liquid outlet pipe and can be directly connected to an external container for further processing. After the bone broth is completely discharged, close the liquid outlet pipe valve, open the cover assembly, and clean the preparation tank, rotating rod 3, stirring rod 4, and other components to prepare for the next bone broth preparation.

[0022] Reference Figures 4-5 The cover assembly includes a cover 11 and two symmetrical vertical rods 12 fixedly installed on the lower surface of the cover 11. Mounting frames 13 are symmetrically fixedly installed on the side walls of the body 1. The two vertical rods 12 are vertically slidably inserted into the two mounting frames 13 respectively. The diameter of the cover 11 is larger than the diameter of the body 1. The cover 11 is locked by a locking assembly. Figure 6 and Figure 9 As shown, the locking assembly includes two spring rods 16 horizontally fixedly installed on the side walls of the two vertical rods 12, and two triangular locking blocks 17 fixedly installed on the ends of the two spring rods 16. A stop plate 18 is fixedly installed on the bottom side wall of the mounting frame 13, as shown. Figure 14 As shown, the upper surface of the abutment plate 18 corresponds to the inclined surface of the locking block 17, and the length of the abutment plate 18 is less than the length of the inclined surface of the locking block 17. The two spring rods 16 are controlled to retract together by a pulling component. The pulling component includes two L-shaped plates 19 respectively fixedly sleeved on the free ends of the two spring rods 16 and two pulling blocks 20 respectively fixedly installed on the upper surfaces of the two L-shaped plates 19. A U-shaped groove 21 is provided on the upper surface of the cover 11, and the two L-shaped plates 19 are vertically slidably inserted into the two ends of the U-shaped groove 21, as shown. Figure 4 and Figure 12 As shown, the upper surface of the cover 11 has multiple round openings, and multiple mounting blocks 14, each covering multiple round openings, are fixedly installed on the upper surface of the cover 11. The top of the mounting blocks 14 has multiple air holes 15 in a circumferential shape.

[0023] When the cover 11 completely covers the preparation groove opening at the top of the machine body 1, the cover assembly is in a locked state. At this time, the lower surface of the cover 11 is in contact with the top of the machine body 1, and the vertical rod 12 slides down along the mounting frame 13 to a preset position. The triangular locking block 17 at the end of the spring rod 16 on the side wall of the vertical rod 12 moves down to a specific height inside the mounting frame 13. The top straight edge of the locking block 17 is tightly abutted against the lower surface of the abutment plate 18 fixed to the bottom side wall inside the mounting frame 13. The abutment plate 18 forms an upward limiting block on the locking block 17, preventing the locking block 17 from moving upward. Thus, the spring rod 16 and the vertical rod 12 restrict the upward movement of the cover 11, achieving a stable lock of the cover 11 and preventing the cover 11 from loosening due to vibration during equipment operation.

[0024] When it is necessary to open the cover 11, the operator holds the pull blocks 20 at both ends of the U-shaped groove 21 on the upper surface of the cover 11 and applies horizontal force in the direction of mutual approach. The pull blocks 20 are fixedly connected to the L-shaped plates 19. The two L-shaped plates 19 are vertically slidably inserted into both ends of the U-shaped groove 21 and fixedly sleeved on the free end of the spring rod 16. Therefore, when the pull blocks 20 approach each other, they will drive the two spring rods 16 to retract together in the direction of approaching the vertical rod 12.

[0025] During the retraction of the spring rod 16, the locking block 17 at its end moves synchronously toward the vertical rod 12 until the top straight edge of the locking block 17 completely disengages from the lower surface of the abutment plate 18, that is, the upper surface of the locking block 17 no longer abuts against the lower surface of the abutment plate 18. At this time, the limiting effect of the abutment plate 18 on the locking block 17 disappears, and the unlocking is completed. After unlocking, keep the pull blocks 20 close to each other to prevent the spring rod 16 from resetting and causing the locking block 17 to contact the stop plate 18 again. Pull the cover 11 vertically upwards, and the vertical rod 12 slides vertically upwards along the mounting frame 13, causing the locking block 17 to move upwards synchronously until the cover 11 is completely separated from the preparation groove. Then stop applying force and move the cover 11 to the side to expose the groove.

[0026] When it is necessary to cover the opening of the preparation tank, move the cover 11 directly above the opening of the preparation tank, so that the two vertical rods 12 on the lower surface of the cover 11 are aligned with the two mounting frames 13 on the side wall of the machine body 1. Then slowly lower the cover 11. During the downward movement of the cover 11, the vertical rods 12 slide vertically down along the mounting frames 13, and the locking block 17 moves down synchronously with the vertical rods 12. When the inclined surface of the locking block 17 contacts the upper surface of the abutment plate 18, continue to lower the cover 11. The upper surface of the abutment plate 18 generates a horizontal abutment on the inclined surface of the locking block 17, forcing the locking block 17 to move closer to the vertical rods 12, and the spring rod 16 retracts accordingly.

[0027] Continue lowering the cover 11 until the lower surface of the cover 11 is in contact with the top of the body 1. At this time, the inclined surface of the locking block 17 completely slides over the upper surface of the abutment plate 18, the pressure of the abutment plate 18 on the locking block 17 disappears, the spring rod 16 automatically resets and extends, driving the locking block 17 to pop out away from the vertical rod 12. Finally, the top straight edge of the locking block 17 abuts against the lower surface of the abutment plate 18 again, forming a limit lock. The cover 11 cannot move up, and the closing and locking operation is completed.

[0028] During the bone broth simmering process, the steam generated in the preparation tank rises from the tank and enters the mounting block 14 fixed to the upper surface of the cover 11 through multiple round openings. After a short stay inside the mounting block 14, the steam is slowly discharged to the outside of the equipment through multiple circumferentially shaped air holes 15 on the top of the mounting block 14, achieving the effect of "smooth steam discharge and no broth splashing".

[0029] Reference Figure 6 and Figure 10 Two locking plates 22 are fixedly installed on the top side wall inside the mounting frame 13. The length of the locking plates 22 is greater than the length of the locking block 17. Figure 15 As shown, a locking space for locking the locking block 17 is formed between the two locking plates 22.

[0030] Pull the unlocked cover 11 upwards, and the vertical rod 12 slides up along the mounting frame 13, causing the spring rod 16 and locking block 17 to rise synchronously. When the cover 11 moves up until the preparation tank opening is fully exposed and there is sufficient operating space, release the two pull blocks 20. The two spring rods 16 automatically reset and push the locking block 17 to pop out away from the vertical rod 12. At this time, the locking block 17 is just locked into the locking space between the two locking plates 22 fixed on the top side wall of the mounting frame 13. Since the length of the locking plate 22 is greater than the length of the locking block 17, it can stably restrict the up and down movement of the locking block 17, thereby fixing the position of the cover 11 through the vertical rod 12, preventing the cover 11 from sliding down due to its own weight, eliminating the need for the operator to continuously pull it, and improving the convenience of operation.

[0031] When the cover 11 needs to be closed, push the pull block 20 towards the middle to retract the spring rod 16 and disengage the locking block 17 from the locking space of the two locking plates 22, thereby releasing the height lock. Then the cover 11 can be smoothly lowered until it covers the opening of the preparation groove and completes the bottom locking through the abutment plate 18. At this time, the locking plates 22 do not interfere with the downward movement of the cover 11.

[0032] Reference Figure 4 As shown, a U-shaped handle 6 is symmetrically fixed on the upper surface of the cover 11, and the surface of the handle 6 is provided with anti-slip texture.

[0033] When the unlocked cover 11 needs to be lifted, the operator can hold the U-shaped handles 6 symmetrically fixed on the upper surface of the cover 11 with both hands. The U-shaped structure fits the hand grip posture, making it easy to apply force and easily move the cover 11 and the vertical rod 12 upward along the mounting frame 13. There is no need to directly contact the edge of the cover 11, which improves the comfort of operation. The anti-slip texture increases the friction between the hand and the handle 6, which can effectively prevent slippage, especially when the hands are covered with oil or soup. This ensures that the operator can apply stable force when lifting the cover 11, prevents the cover 11 from accidentally slipping, and improves the safety of operation.

[0034] In this invention, the covering component covers the opening of the preparation tank, which can initially block the path of broth splashing during subsequent simmering. The drive motor 5 drives the rotating rod 3 and multiple circumferentially distributed stirring rods 4 to rotate synchronously, which can fully stir and mix the high-temperature broth at the bottom and the low-temperature broth at the top of the preparation tank, quickly breaking the temperature stratification of the broth and avoiding the imbalance of a continuously high temperature at the bottom and an insufficient temperature at the top. In addition, the stirring process can slow down the speed at which bubbles rise from the bottom of the preparation tank to the liquid surface, reducing the impact force of the bubbles breaking when they reach the liquid surface and reducing broth splashing caused by bubble bursting. At the same time, the circulation formed by stirring can make the bone broth components more evenly mixed, avoiding local scorching of raw materials due to overheating, thus meeting the dual requirements of anti-splashing and bone broth quality. The electric heating wire 2 Part of the hot air generated by heating enters the internal cavity 7 of the rotating rod 3 through multiple vents 10 at the end of the rotating rod 3, forming a unique hot air circulation system. On the one hand, the hot air in the cavity 7 can "preheat and keep warm" the rotating rod 3, preventing the rotating rod 3 from forming a temperature difference with the hot soup due to excessively low temperature, and preventing the soup from dripping to the bottom of the preparation tank after condensation on the surface of the rotating rod 3, causing local splashing. On the other hand, the hot air enters the rectangular groove 9 of the stirring rod 4 through the opening 8 of the rotating rod 3, and is dispersed into the soup in each area of ​​the preparation tank as the stirring rod 4 rotates, replenishing the soup with uniform heat, avoiding convection turbulence caused by sudden drops in local temperature, and promoting internal circulation of the soup through slight disturbance of the hot air, reducing the possibility of bubbles agglomerating and forming large-volume bubbles, and further enhancing the anti-splashing effect.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
