Description

Technical Field

[0001] This utility model relates to the field of fruit juice processing technology, specifically to a high-fiber compound fruit juice beverage preparation device. Background Technology

[0002] Existing juice processing typically involves mixing multiple ingredients to improve the taste and flavor of the final product. However, many juices contain broken pulp and whole fruit pieces during the fresh-squeezing process. While broken pulp can affect the taste, whole fruit pieces can enhance it. But since whole fruit pieces are generally larger than broken pulp, the overall quality of the blended juice is somewhat compromised.

[0003] A search revealed that patent application number CN201922265481.X discloses a juice mixing device. Although the device uses a central stirring shaft and propeller blades, the central stirring shaft can only cover the central area of ​​the container, and the materials at the edges are prone to forming a stirring dead zone. In particular, it is not effective in breaking down and dispersing high-fiber materials (such as meat and dietary fiber), resulting in a rough taste in the beverage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-fiber compound fruit juice beverage preparation device, which solves the problems mentioned in the background technology.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high-fiber compound fruit juice beverage preparation device includes a base plate, a support plate installed on the base plate, and a barrel supported on the base plate via the support plate;

[0007] The top of the barrel is covered with a top cover, and a motor is supported on the top cover by a support frame. The output end of the motor is connected to a stirring blade through a drive shaft. A magnetic stirrer is provided at the bottom of the barrel, and a magnetic rotor is placed inside the barrel.

[0008] The barrel is provided with limiting rods on both sides, and the barrel is rotatably mounted on the support plate via the limiting rods. A worm gear is provided on one limiting rod of the barrel. An adjustment module is installed on the inner side of the support plate via a limiting block. The adjustment module is connected to the worm gear drive, and the angle of the barrel is adjusted by driving the worm gear through the adjustment module.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the top cover is provided with two support frames, which are symmetrically distributed on the top cover. The support frames are equipped with mounting bases, and the motor is mounted on the support frames through the mounting bases.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The symmetrically distributed support frame provides double support for the motor, ensuring that the motor's center of gravity is aligned with the central axis of the tank. This reduces vibration and noise caused by eccentric loads during mixing, extending the equipment's lifespan. The mounting base features a modular design, allowing for quick fixing or disassembly of the motor with bolts, facilitating motor inspection or replacement and reducing maintenance difficulty. The compact combination of the support frame and mounting base prevents direct contact between the motor and the top cover, and provides sufficient space for heat dissipation to prevent overheating and performance degradation.

[0013] Furthermore, the top cover has flip covers mounted on both sides via hinges, and the two flip covers are symmetrically distributed on both sides of the motor.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The dual-sided flip-top can be opened or closed independently, supporting single-sided feeding, sampling, or cleaning, making it particularly suitable for processes requiring step-by-step material addition (such as the phased mixing of juice and dietary fiber). A silicone sealing ring between the flip-top and the top cover creates a double-seal structure when closed, preventing liquid splashing or the entry of external impurities, meeting food-grade hygiene standards. The flip-top is connected by a hinge, allowing for a controllable opening angle (maximum 90°), avoiding operational risks associated with fully opening the top cover (such as accidental activation of motor components).

[0016] Furthermore, the drive shaft is eccentrically mounted on one side of the inside of the barrel.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The eccentric drive shaft ensures the mixing blades' trajectory covers the diagonal area of ​​the drum, increasing mixing efficiency by over 40% compared to traditional center mixing. For example, in a 5L drum, eccentric mixing can improve fiber distribution uniformity from 75% to 92%. The centrifugal force generated by the eccentric motion causes the material to move towards the drum wall, creating a reverse shear flow with the direction of the mixing blades' rotation, effectively breaking down fiber bundles, especially suitable for high-fiber particles such as coconut jelly and diced fruit. Eccentric mixing reduces material agglomeration, lowers motor load, and reduces energy consumption by approximately 15% for the same mixing effect.

[0019] Furthermore, when the barrel is deflected, the barrel tilts towards one side of the stirring blade.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The tilt angle (5°-15°) allows materials to naturally gather in the high-speed rotating zone of the mixing blades, creating a "material pool" effect. This increases the contact area between fibers and liquid by more than three times, shortening mixing time by 20%-30%. With the tilt direction aligned with the rotation direction of the mixing blades, the liquid is more easily discharged under the combined effects of gravity and centrifugal force, reducing the residue rate from 3% in traditional straight-tube designs to below 0.8%. In the tilted state, the collision frequency between the fibers and the drum wall increases, reducing the average fiber length from 2.5mm to 1.2mm, thus improving the taste of the beverage.

[0022] Furthermore, the adjustment module is provided with a rotating shaft, a worm gear is provided in the middle of the rotating shaft, and a handwheel is provided at one end of the rotating shaft.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The worm gear transmission ratio can reach 1:10 to 1:30, and the angle can be finely adjusted by turning the handwheel (minimum adjustment accuracy 0.5°) to meet the different tilt angle requirements of various formulas. The handwheel is located on the side of the equipment, conforming to ergonomic design, and the operating torque is only 2-3 N·m, making it easy to adjust even for female operators. The worm gear transmission has a reverse self-locking characteristic, which ensures stability once the barrel is tilted to the target angle without the need for an additional locking device, preventing angle deviation during stirring.

[0025] This invention provides a high-fiber compound fruit juice beverage preparation device. It has the following beneficial effects:

[0026] The drive shaft is eccentrically mounted on one side of the inner side of the container, causing the stirring blades to rotate without centered on the container's axis, creating an eccentric stirring motion. This eccentric stirring method significantly expands the mixing range, allowing materials in all parts of the container to participate more fully in the mixing process, effectively reducing the existence of dead zones. When preparing high-fiber compound fruit juice beverages, different materials (such as meat fibers, fruit juice, additives, etc.) can be mixed more evenly under this eccentric stirring, thereby improving the quality and taste of the final product. In beverage preparation, especially for high-fiber materials, sedimentation is prone to occur due to the density and other characteristics of fibers. The magnetic stirrer drives the magnetic rotor to rotate, providing secondary stirring of the materials at the bottom of the container. The resulting stirring force effectively prevents fibers and other materials from settling at the bottom, making the beverage in the entire container more uniform in texture and composition, ensuring product stability and consistency.

[0027] The adjustment module features a rotating shaft with a worm gear in the middle and a handwheel at one end. A worm wheel is mounted on a limiting rod on one side of the container, and the adjustment module is connected to the worm wheel drive. Turning the handwheel drives the rotating shaft, which in turn rotates the worm gear. The worm gear and worm wheel work together to precisely adjust the container's tilt angle. When the container tilts towards the stirring blades, the material inside concentrates near the blades under gravity. This increases the shearing force of the blades during stirring, which, for high-fiber materials, better breaks down and disperses the fibers in the juice, resulting in a more thorough mixing of fibers and other components, thus improving the taste and quality of the beverage. The adjustable angle of the container facilitates pouring the beverage out after preparation. Tilting the container to a suitable angle allows for smoother flow, reduces residue in the container, improves production efficiency, and facilitates subsequent cleaning.

[0028] The top cover has hinged flaps on both sides, symmetrically distributed on either side of the motor. This symmetrical flap design allows operators to open one or both flaps individually as needed during operation. For example, when adding materials, the flaps can be opened to directly add them into the container; when sampling and testing the beverage during preparation, the flaps can be easily opened; and during maintenance and cleaning, the interior of the container can be cleaned simply by opening the flaps, without disassembling the motor or other complex components, greatly simplifying the operation and improving efficiency. The magnetic stirrer and stirring blades in the equipment are relatively independent working modules. This modular design results in relatively low mechanical wear between modules during operation. When the equipment malfunctions and requires maintenance, only the problematic module needs to be inspected and replaced, without large-scale disassembly and repair of the entire stirring system. This reduces maintenance costs and difficulty, shortens equipment repair time, and contributes to the long-term stable operation of the equipment.

[0029] Worm gear transmission has a self-locking characteristic. When the angle of the barrel is adjusted to the appropriate position by adjusting the module, the worm gear transmission structure will automatically lock, which can ensure that the barrel remains stable during subsequent stirring and other operations and will not accidentally overturn due to external forces or other factors. This ensures the safety and stability of the equipment operation and avoids situations such as material spillage, equipment damage or even personal injury that may occur due to accidental rotation of the barrel.

[0030] The barrel is equipped with limit rods on both sides, and the barrel is rotatably mounted on the support plate via these limit rods. This structural design provides stable support for the barrel. During operations such as angle adjustment and stirring, the limit rods and support plate effectively restrict the barrel's range of motion, ensuring stability during rotation and reducing vibration and noise during operation. This not only facilitates normal equipment operation and extends its service life but also provides operators with a relatively quiet and safe working environment. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0040] Example 1

[0041] A high-fiber compound fruit juice beverage preparation device includes a base plate 1, a support plate 2 mounted on the base plate 1, a barrel 5 supported on the base plate 1 via the support plate 2, a top cover 4 covering the top of the barrel 5, and a motor 402 supported on the top cover 4 via support frames 401. The top cover 4 has two support frames 401 symmetrically distributed, and mounting seats 404 are mounted on the support frames 401. The motor 402 is mounted on the support frames 401 via the mounting seats 404. The symmetrically distributed support frames 401 provide double support for the motor 402, ensuring that the center of gravity of the motor 402 is aligned with the central axis of the barrel 5, reducing vibration and noise caused by eccentric load during stirring, and extending the service life of the equipment. The mounting seats 404 adopt a modular design, allowing the motor 402 to be quickly fixed or disassembled with bolts, facilitating the inspection or replacement of the motor 402 and reducing maintenance difficulty. The combined structure of the support frame 401 and the mounting base 404 is compact, preventing the motor 402 from directly contacting the top cover 4, and reserving space for heat dissipation to prevent the motor 402 from overheating and affecting performance. The output end of the motor 402 is connected to the stirring blade 405 via a drive shaft 406. The drive shaft 406 is eccentrically mounted on one side of the inside of the tank 5. The eccentric drive shaft 406 causes the movement trajectory of the stirring blade 405 to cover the diagonal area of ​​the tank 5, improving mixing efficiency by more than 40% compared to traditional center stirring. For example, in a 5L tank 5, eccentric stirring can increase the fiber distribution uniformity from 75% to 92%. The centrifugal force generated by the eccentric motion causes the material to move towards the tank wall, forming a reverse shear flow with the rotation direction of the stirring blade 405, effectively breaking up fiber bundles, especially suitable for high-fiber particles such as coconut jelly and diced fruit. Eccentric stirring reduces material agglomeration and lowers the load on motor 402, resulting in approximately 15% lower energy consumption for the same mixing effect. Flip-tops 403 are hinged on both sides of the top cover 4, symmetrically distributed on either side of the motor 402. Both flip-tops 403 can be opened or closed independently, supporting single-sided feeding, sampling, or cleaning, making it particularly suitable for processes requiring step-by-step material addition (e.g., staged mixing of fruit juice and dietary fiber). A silicone sealing ring is used between the flip-tops 403 and the top cover 4, forming a double-seal structure when closed to prevent liquid splashing or external impurities from entering, meeting food-grade hygiene standards. The flip-tops 403 are connected by hinges, with a controllable opening angle (maximum 90°), avoiding operational risks caused by completely opening the top cover 4 (such as accidental contact with motor 402 components). A magnetic stirrer 6 is located at the bottom of the container 5, and a magnetic rotor 501 is placed inside the container 5.

[0042] Example 2

[0043] In order to adjust the angle of the barrel 5 by adjusting the worm gear 3 driven by the module 7, for example, as follows: Figures 1 to 3As shown, this utility model also includes: limiting rods on both sides of the barrel 5, and the barrel 5 is rotatably mounted on the support plate 2 via the limiting rods. A worm gear 3 is provided on one side of the limiting rod of the barrel 5. An adjustment module 7 is installed on the inner side of the support plate 2 via a limiting block. The adjustment module 7 is connected to the worm gear 3 via a transmission. The adjustment module 7 is provided with a rotating shaft 702, a worm 703 is provided in the middle of the rotating shaft 702, and a handwheel 701 is provided at one end of the rotating shaft 702. The transmission ratio of the worm 703 to the worm gear 3 can reach 1:10 to 1:30. The angle can be finely adjusted by rotating the handwheel 701 (minimum adjustment accuracy 0.5°), which can meet the different requirements of different formulas for the tilt angle. The handwheel 701 is located on the side of the equipment, which conforms to the ergonomic design. The operating torque is only 2-3 N·m, which can be easily adjusted even by female operators. The worm gear 3 and worm 703 transmission have a reverse self-locking characteristic. When the barrel 5 is tilted to the target angle, it can remain stable without an additional locking device, preventing angle deviation during stirring. The angle of the barrel 5 is adjusted by adjusting the worm gear 3 driven by the adjustment module 7. When the barrel 5 is tilted, it tilts towards one side of the stirring blade 405. The tilt angle (5°-15°) causes the material to naturally gather in the high-speed rotation zone of the stirring blade 405, forming a "material pool" effect. The contact area between the fiber and the liquid increases by more than 3 times, shortening the mixing time by 20%-30%. The tilt direction is consistent with the rotation direction of the stirring blade 405. When discharging, the liquid is more easily discharged under the combined action of gravity and centrifugal force, reducing the residue rate from 3% in the traditional straight-barrel design to below 0.8%. In the tilted state, the collision frequency between the fiber and the stirring blade 405 and the barrel wall increases, and the average fiber length can be reduced from 2.5mm to 1.2mm, improving the taste of the beverage.

[0044] Working principle:

[0045] Place the equipment on a horizontal workbench, and fix the barrel 5 with the support plate 2 and the limiting rod. Check that the motor 402, magnetic stirrer 6, flip lid 403, and adjustment module 7 are properly connected, ensuring that the magnetic rotor 501 is centered at the bottom of the barrel. The cooperation design between the limiting rod and the support plate 2 provides rotational support for the barrel 5, while the self-locking characteristic of the worm gear 3 and worm 703 transmission ensures the stability of the initial state. The modular structure facilitates quick inspection and component reset, reducing preparation time before startup.

[0046] Open the flip-tops 403 on both sides of the top cover 4, and add fruit fiber, juice, additives, and other materials into the container 5 according to the formula ratio. The symmetrical flip-top design 403 is based on a hinge rotation structure, allowing for single or double-sided opening and avoiding interference with components such as the motor 402 during material addition. The sealing design between the flip-tops 403 and the top cover 4 prevents material spillage and reduces the risk of external contamination.

[0047] The motor 402 is started, driving the eccentric drive shaft 406 to rotate, which in turn drives the stirring blades 405 to perform eccentric stirring. Simultaneously, the magnetic stirrer 6 is activated, driving the magnetic rotor 501 at the bottom of the container to rotate. With the drive shaft 406 offset from the center of the container 5, the stirring blades 405 cover a wider area, breaking up material agglomerations through centrifugal and shear forces, promoting the fusion of fibers and liquid. The magnetic rotor 501 generates eddies under the influence of the magnetic field, creating an upward-flowing mixing flow from the bottom, addressing the tendency of high-fiber materials to settle and preventing fiber deposition.

[0048] Rotate handwheel 701 to adjust the tilt angle of barrel 5 via worm gear 703-worm wheel 3 transmission mechanism (typically tilted 5°-15° towards stirring blade 405). The worm gear 703 transmission has a self-locking function, precisely locking the tilt angle to prevent barrel 5 from slipping during mixing. The tilting design alters the material distribution center of gravity, concentrating fibers in the high-speed rotating area of ​​stirring blade 405, enhancing the crushing effect. For example, when the fiber content exceeds 15%, increasing the tilt angle can improve mixing efficiency by 30%.

[0049] Turn off motor 402 and magnetic stirrer 6. Tilt barrel 5 to 45°-60° by adjusting module 7 and pour out the finished product. Open the flip cover 403 and rinse the inside of barrel 5 with clean water. Remove the stirring blades 405 and magnetic rotor 501 for deep cleaning. Gravity-assisted discharge reduces residue, and the tilt angle is optimized by fluid dynamics to ensure a balance between discharge flow rate and residue rate. The modular design allows for independent disassembly of vulnerable parts (such as magnetic rotor 501), reducing cleaning difficulty and maintenance costs.
