Description

Technical Field

[0001] This utility model relates to the field of confectionery processing equipment technology, and in particular to a raw material mixing device for fructose processing. Background Technology

[0002] In the food industry and biochemical fields, fructose, as an important sweetener and functional ingredient, is widely used in the production of beverages, confectionery, baked goods, and pharmaceutical intermediates. Its processing involves core steps such as raw material pretreatment, enzymatic hydrolysis / conversion, purification, crystallization, and drying. Raw material mixing, as a key step in the pretreatment stage, directly determines the uniformity of the subsequent reaction system, reaction efficiency, and the purity and quality of the final fructose product, making it a fundamental step in ensuring the stable operation of the entire production line.

[0003] The prior art patent document CN221979954U discloses an auxiliary material addition device for fructose processing, belonging to the field of candy processing equipment. It includes a mixing tank and a tank cover. The tank cover is located on the top of the mixing tank. A motor bracket is located on the upper surface of the tank cover, and a stirring motor is located on the lower surface of the motor bracket. A stirring roller is located below the stirring motor, and a connecting block is located on the surface of the stirring roller. A stirring paddle is fixed to one end of the connecting block, and a connecting plate is located at one end of the stirring paddle. A brush is located at one end of the connecting plate and is attached to the inner wall of the mixing tank. Clamping plates are located on both sides of the connecting plate. This invention allows candy raw materials to enter the mixing tank through a raw material inlet pipe and a candy raw material inlet, and auxiliary materials to enter the mixing tank through an auxiliary material inlet pipe and a candy auxiliary material inlet. Starting the stirring motor causes the stirring shaft to rotate the stirring roller, which in turn causes the stirring paddle connected to the stirring roller to rotate and mix the candy and auxiliary materials. The brush connected to the stirring paddle then scrapes residual material from the inner wall of the mixing tank.

[0004] While the aforementioned patents can address the issue of difficult-to-clean residues on the inner walls of mixing tanks to some extent, the transport stability of core ingredients such as glucose syrup and sucrose during fructose processing is poor. These ingredients are easily affected by factors such as changes in their viscosity, leading to fluctuating feed amounts. This not only causes an imbalance in the ratio of main to auxiliary ingredients within the mixing tank, affecting the consistency of fructose product quality, but also results in material accumulation due to sudden increases in feed amount, increasing the stirring load and potentially causing equipment malfunctions. Furthermore, the device relies solely on the rotation of the stirring paddle for a single mixing operation. After the premixed and main ingredients enter the mixing tank, they can only slowly diffuse and mix under the action of the stirring paddle, lacking a structural design that promotes rapid blending. This results in a prolonged mixing process, reducing overall production efficiency and causing localized agglomeration of some ingredients within the mixing tank due to untimely mixing. This makes it difficult to meet user needs and has low practicality. Utility Model Content

[0005] The purpose of this invention is to provide a raw material mixing device for fructose processing, which solves the problems of unstable main material conveying and low mixing efficiency between premixed raw materials and main materials during fructose processing.

[0006] To achieve the above objectives, this utility model provides a raw material mixing device for fructose processing, including a base plate, a main mixing tank fixedly connected to the top right side of the base plate, a secondary mixing tank fixedly connected to the top of the base plate, a conveying mechanism provided on the top left side of the base plate, and a mixing mechanism provided outside the secondary mixing tank;

[0007] The conveying mechanism includes a connecting frame, the bottom of which is fixedly connected to the top left side of the base plate. A main feed inlet is fixedly connected to the top of the connecting frame. A rotating motor is fixedly connected to the outer left side of the connecting frame. A conveying pipe is fixedly connected to the outer right side of the connecting frame. A auger conveyor is fixedly connected to the output end of the main feed inlet. A discharge port is fixedly connected to the top of the conveying pipe. A material control valve is fixedly connected to the bottom inner side of the discharge port. A feed pipe is fixedly connected to the other end of the conveying pipe. A feeding assembly is installed on the top of the auxiliary mixing tank.

[0008] The mixing mechanism includes a secondary drive motor and a primary drive motor. The secondary drive motor is externally and fixedly connected to the top of the secondary mixing tank, and the primary drive motor is externally and fixedly connected to the top of the primary mixing tank. A secondary rotating rod is fixedly connected to the output end of the secondary drive motor, and a secondary stirring rod is fixedly connected to the outside of the secondary rotating rod. A movable scraper is rotatably connected to the other end of the secondary stirring rod. A primary rotating rod is fixedly connected to the output end of the primary drive motor, and a primary stirring rod is fixedly connected to the outside of the primary rotating rod. An inclined scraper is fixedly connected to the other end of the primary stirring rod. A discharge pipe is fixedly connected to the bottom of the primary mixing tank.

[0009] The feeding assembly includes a secondary feed inlet and a main feed inlet. The secondary feed inlet is fixedly connected to the outside of the top of the secondary mixing tank, and the main feed inlet is fixedly connected to the outside of the top of the main mixing tank.

[0010] The external end of the auger conveyor is rotatably connected to the inside of the conveying pipe, and the other end of the auger conveyor is rotatably connected to the inside of the feed pipe.

[0011] The top of the discharge port is fixedly connected to the bottom of the secondary mixing tank, and the bottom of the feed pipe is fixedly connected to the top outside of the main mixing tank.

[0012] The main rotating rod is externally mounted inside the main mixing tank, and the inclined scraper is externally slidably connected to the inner wall of the auxiliary mixing tank.

[0013] The auxiliary rotating rod is externally mounted inside the auxiliary mixing tank, and the movable scraper is externally slidably connected to the inner wall of the discharge port.

[0014] The rotating motor drives the auger to rotate inside the conveying pipe, conveying the material falling from the main feed inlet to the connecting frame to the feed pipe. The material control valve controls the opening of the discharge port, allowing the material from the secondary mixing tank to leak quantitatively into the conveying pipe and be conveyed to the feed pipe, thus mixing and conveying the material entering the connecting frame together with the material entering the secondary mixing tank.

[0015] This utility model relates to a raw material mixing device for fructose processing.

[0016] 1. In this utility model, a rotating motor drives a auger conveyor to rotate inside the conveying pipe, stably conveying the main material in the connecting frame towards the feed pipe. The size of the opening is controlled by adjusting the control valve inside the discharge port. In conjunction with the conveying action of the auger conveyor, the premixed raw materials in the secondary mixing tank are quantitatively leaked into the conveying pipe, achieving the effect of preliminary mixing with the main material during conveying. This shortens the subsequent total mixing time, thereby achieving stable conveying of the main material during the fructose processing raw material conveying process, and preliminary fusion with the premixed raw materials in advance, thus shortening the subsequent total mixing time in the mixing tank and improving the overall mixing efficiency.

[0017] 2. In this utility model, the auxiliary drive motor drives the auxiliary rotating rod to rotate, and the auxiliary rotating rod drives the auxiliary stirring rod to perform preliminary pretreatment of the raw materials in the auxiliary mixing tank. The auxiliary stirring rod drives the movable scraper to slide against the inner wall of the discharge port to clean the sticky residue on the inner wall of the discharge port in real time. The main drive motor drives the main rotating rod to rotate, and the main rotating rod drives the main stirring rod to stir in different height areas in the total mixing tank. The main stirring rod drives the inclined scraper to slide against the inner wall of the total mixing tank to scrape off the residual material on the tank wall and avoid the material from staying for a long time. This solves the problems of uneven mixing of raw materials that are prone to agglomeration in fructose processing, blockage of sticky material at the discharge port, and deterioration of residual material in the total mixing tank.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a raw material mixing device for fructose processing, including a base plate 1. The base plate 1 serves as the basic support structure of the entire device, providing a stable installation platform for the main mixing tank 2 and the auxiliary mixing tank 3, preventing positional displacement due to vibration during equipment operation. The main mixing tank 2 is fixedly connected to the top right side of the base plate 1. The main mixing tank 2 serves as the core container for final material mixing, and its large internal volume can accommodate multi-component materials from the conveying mechanism 4, providing sufficient space for thorough mixing. The auxiliary mixing tank 3 is fixedly connected to the top of the base plate 1. The auxiliary mixing tank 3 is used for preliminary pretreatment of small amounts of easily agglomerated or highly sensitive raw materials, which can avoid uneven mixing caused by direct entry into the main mixing tank 2. The conveying mechanism 4 is provided on the top left side of the base plate 1, and the mixing mechanism 5 is provided on the outside of the auxiliary mixing tank 3.

[0026] The conveying mechanism 4 includes a connecting frame 41, which serves as a transitional connection between the main feed inlet 42 and the conveying pipe 44. The connecting frame 41 guides the material falling from the main feed inlet 42 precisely into the working area of ​​the auger conveyor 45, preventing material spillage. The bottom of the connecting frame 41 is fixedly connected to the top left side of the base plate 1. This fixed connection ensures the stability of the connecting frame 41 during high-speed operation of the auger conveyor 45, preventing blockage of the material conveying channel due to vibration. The top of the connecting frame 41 is fixedly connected to the main feed inlet 42, which adopts a funnel-shaped structure that is wider at the top and narrower at the bottom. This facilitates quick addition of main material by operators or feeding equipment, while reducing material residue during the feeding process. A rotating motor 43 is fixedly connected to the outer left side of the frame 41. The rotating motor 43 serves as the power source for the auger conveyor 45, and its adjustable speed can adapt to the conveying needs of different materials. A conveying pipe 44 is fixedly connected to the outer right side of the frame 41. The conveying pipe 44 is a closed tubular structure that can prevent dust contamination or moisture absorption of materials during material conveying, and also prevent material splashing when the auger conveyor 45 is running. The output end of the main feed inlet 42 is fixedly connected to the auger conveyor 45. The auger conveyor 45 propels the material forward through the rotation of the spiral blades, achieving continuous and stable material conveying and preventing material accumulation. A discharge port 47 is fixedly connected to the top of the conveying pipe 44. 47 serves as the connecting channel between the secondary mixing tank 3 and the conveying pipe 44. Its vertical downward structure ensures that the premixed material in the secondary mixing tank 3 falls accurately into the conveying pipe 44 and fully contacts the main material. A control valve 46 is fixedly connected to the bottom inner side of the discharge port 47. The control valve 46 can control the discharge speed and discharge amount by adjusting the valve opening degree. For example, for trace additives, the opening degree can be reduced to achieve precise metering and meet the formulation requirements of different products. The other end of the conveying pipe 44 is fixedly connected to the feed pipe 48. The feed pipe 48 adopts a vertical angle design, which can use gravity to assist the material to enter the main mixing tank 2 and reduce the power loss of the auger conveyor 45. The top of the secondary mixing tank 3 is equipped with a feeding assembly. 49. The external rotatable connection of the auger conveyor 45 is connected to the inside of the conveying pipe 44 to ensure that the auger conveyor 45 can operate flexibly in the conveying pipe 44. The other end of the auger conveyor 45 is rotatably connected to the inside of the feed pipe 48. Through the rotational cooperation with the feed pipe 48, the mixed material in the conveying pipe 44 can be completely pushed to the main mixing tank 2, avoiding material residue at the end of the pipe. The top of the discharge port 47 is fixedly connected to the bottom of the auxiliary mixing tank 3 to ensure that the premixed material in the auxiliary mixing tank 3 can be completely discharged, reducing the waste of raw materials caused by residue in the tank. The bottom of the feed pipe 48 is fixedly connected to the top outside of the main mixing tank 2. By feeding material on the top outside, the material can slide down along the inner wall of the main mixing tank 2.

[0027] The rotating motor 43 drives the auger conveyor 45 to rotate inside the conveying pipe 44, conveying the material falling from the main feed port 42 to the connecting frame 41 to the feed pipe 48. This achieves precise matching between the material conveying speed and the auger rotation speed, ensuring stable and controllable main material conveying volume. The material control valve 46 controls the opening of the discharge port 47, allowing the material from the secondary mixing tank 3 to leak quantitatively into the conveying pipe 44 and be conveyed to the feed pipe 48. This control method can achieve precise adjustment of the ratio of premixed material to main material, avoiding the impact of material ratio deviation on the quality of subsequent fructose products. The material entering the connecting frame 41 is mixed and conveyed together with the material entering the secondary mixing tank 3. This initial mixing during the conveying process can shorten the stirring time of the main mixing tank 2 and improve overall production efficiency.

[0028] The feeding assembly 49 includes a secondary feed inlet 491 and a main feed inlet 492. The secondary feed inlet 491 is externally fixedly connected to the top outer side of the secondary mixing tank 3, which facilitates feeding by the operator. The main feed inlet 492 is externally fixedly connected to the top outer side of the main mixing tank 2, which allows the main material to directly enter the middle area of ​​the main mixing tank 2, facilitating rapid mixing with the mixed materials delivered by the conveying mechanism 4.

[0029] like Figures 2 to 4As shown, the mixing mechanism 5 includes a secondary drive motor 51 and a main drive motor 55. The design of two independent drive motors allows for separate control of the stirring speeds of the secondary mixing tank 3 and the main mixing tank 2, meeting the needs of different mixing stages. The secondary drive motor 51 is externally fixedly connected to the top of the secondary mixing tank 3. This top-mounted design ensures that the secondary rotor 52 is vertically centered, preventing eccentricity during stirring and thus avoiding wear on the tank wall. The main drive motor 55 is externally fixedly connected to the top of the main mixing tank 2. This same top-mounted structure ensures the stability of the main rotor 56, ensuring that the main stirring rod 57 can cover most of the area inside the tank. The secondary drive motor 51... The output end of the main drive motor 55 is fixedly connected to a secondary rotating rod 52, which serves as the mounting carrier for the secondary stirring rod 53. This secondary rotating rod 52 transmits the power of the secondary drive motor 51 to the stirring components, achieving synchronous rotation. The secondary stirring rod 53 is fixedly connected to the outside of the secondary rotating rod 52. The secondary stirring rod 53 adopts a symmetrical distribution design to ensure uniform dispersion of materials within the secondary mixing tank 3, preventing localized agglomeration. The other end of the secondary stirring rod 53 is rotatably connected to a movable scraper 54. The movable scraper 54 can slide against the inner wall of the discharge port 47 during stirring, promptly removing any residual sticky materials from the discharge port 47 to prevent blockage. The output end of the main drive motor 55 is fixedly connected to... A main rotating rod 56 is connected, the length of which is adapted to the height of the mixing tank 2. This allows the main stirring rod 57 to be driven to stir at different heights within the tank, eliminating dead zones. The main stirring rod 57 is fixedly connected to the outside of the main rotating rod 56. The main stirring rod 57 employs a multi-layer design to promote rapid fusion of multi-component materials and improve mixing uniformity. An inclined scraper 58 is fixedly connected to the other end of the main stirring rod 57. The inclined scraper 58 is inclined and fits against the inner wall of the mixing tank 2, scraping away residual material on the tank wall during stirring and preventing material from remaining on the tank wall for extended periods. A discharge pipe 59 is fixedly connected to the bottom of the mixing tank 2. The discharge pipe 59 is located at the bottom of the mixing tank. The mixing tank 2 is located at the bottom center, ensuring that the mixed material can be completely discharged, reducing residue at the bottom of the tank. The main rotating rod 56 is externally installed inside the main mixing tank 2, and the inclined scraper 58 is externally slidably connected to the inner wall of the auxiliary mixing tank 3. The sliding connection ensures that the inclined scraper 58 always fits against the tank wall when rotating with the main stirring rod 57, improving the wall cleaning effect. The auxiliary rotating rod 52 is externally installed inside the auxiliary mixing tank 3, and the movable scraper 54 is externally slidably connected to the inner wall of the discharge port 47. The sliding connection allows the movable scraper 54 to clean the inner wall of the discharge port 47 in real time without affecting the material discharge, ensuring smooth material conveying.

[0030] Working principle: During operation, a small amount of easily agglomerated or highly sensitive raw materials are first added to the secondary mixing tank 3 through the secondary feed port 491 of the feeding component 49. At the same time, the main material is added to the connecting frame 41 through the main feed port 42. The secondary drive motor 51 of the mixing mechanism 5 is started, which drives the secondary rotating rod 52 to rotate. The secondary rotating rod 52 synchronously drives the secondary stirring rod 53 to perform preliminary pretreatment on the raw materials in the secondary mixing tank 3, so as to avoid the raw materials from directly entering the main mixing tank 2 and causing uneven mixing. During this process, the other end of the secondary stirring rod 53... The movable scraper 54 slides against the inner wall of the discharge port 47 to clean the sticky material remaining on the inner wall of the discharge port 47 in real time and prevent blockage. Then, the rotating motor 43 of the conveying mechanism 4 is started. The rotating motor 43 drives the auger conveyor 45 to rotate inside the conveying pipe 44, conveying the main material in the connecting frame 41 to the feed pipe 48. At the same time, the material control valve 46 inside the discharge port 47 is adjusted to control the opening size, so that the premixed raw material in the secondary mixing tank 3 leaks into the conveying pipe 44 in a quantitative manner and is initially mixed with the main material during the conveying process.

[0031] After the pre-mixed material enters the total mixing tank 2 through the feed pipe 48, other required main materials are added to the total mixing tank 2 through the main feed port 492 of the feed assembly 49. The main materials directly enter the middle area of ​​the total mixing tank 2 to quickly blend with the pre-mixed material. The main drive motor 55 of the mixing mechanism 5 is started, and the main drive motor 55 drives the main rotating rod 56 to rotate. The main rotating rod 56 drives the main stirring rod 57 to stir in different height areas in the total mixing tank 2. The multi-layer design of the main stirring rod 57 promotes the rapid fusion of multi-component materials to improve the mixing uniformity. The inclined scraper 58 at the other end of the main stirring rod 57 slides against the inner wall of the total mixing tank 2 to scrape off the residual material on the tank wall and avoid the material from staying for a long time. After the material is fully mixed in the total mixing tank 2, the discharge pipe 59 at the bottom of the total mixing tank 2 is opened to discharge the mixed material to the next processing step, realizing the efficient and uniform mixing of fructose processing raw materials.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
