Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to an automatic mixing device. Background Art

[0002] Candy is a kind of confectionery pastry, referring to a snack mainly composed of sugars. If fruits or nuts are coated with sugar coating, they are called sweets. The modern candy processing process includes multiple procedures, such as raw material mixing, cutting, and candy packaging. In the candy raw material mixing procedure, a mixing device is used to stir and mix the candy raw materials to make them more uniform to maintain the taste of the finished product. The raw materials of candies include fillers such as milk powder and spices, and binders such as starch syrup, dextrin, and gelatin. The viscosity of these raw materials is usually relatively large. After the raw material mixing is completed, the discharging speed of the finished product is relatively slow, and it is easy to condense inside the mixing device before plasticity, resulting in a large amount of residue inside the machine and increasing the cleaning difficulty of the machine.

[0003] For this reason, a raw material mixing device for candy processing with the publication number of "CN220369419U" includes two groups of support seats. The top ends of the two groups of support seats are fixedly connected with a lifting seat. One side of the lifting seat is fixedly connected with a mixing barrel. The inner side wall of the lifting seat is fixedly connected with several groups of teeth. One side of the teeth is provided with a lifting block. Both ends of the lifting block are fixedly connected with balance blocks. The end of the balance block far away from the lifting block is fixedly connected with a lifting motor. The output end of the lifting motor is fixedly connected with a gear. The gear is rotatably connected to one end of the balance block. One side of the gear meshes with the teeth inside the lifting seat. One side of the gear is provided with a pressing ball. The top end of the pressing ball is fixedly connected with the bottom end of the lifting block. The shape of the pressing ball fits the shape of the bottom of the mixing barrel. The bottom end of the mixing barrel is fixedly connected with two valve-equipped discharging pipes. The top end of the mixing barrel is fixedly connected with a stirring motor. When this utility model is in use, it accelerates the discharge of raw materials and reduces the internal residue.

[0004] However, for the above-mentioned raw material mixing device for candy processing, although the rotation of the lifting motor drives the rotation of the gear, thereby driving the pressing ball to descend and extruding the raw materials out of the valve-equipped discharging pipes, improving the working efficiency and the cleanliness inside the mixing barrel, there are still the following obvious defects during the use process: Although the inner wall cleanliness of the mixing barrel can be ensured by the extrusion method for discharging materials, there will be a problem that some raw materials will be extruded and adhered to the inner wall during the extrusion discharging due to the certain viscosity of the candy raw materials. Therefore, the inner wall still needs to be cleaned later, and because the candy raw materials are solidified, the cleaning is more troublesome and it is easy to cause damage to the inner wall. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic mixing device to solve the problems raised in the above background art.

[0006] To achieve the above object, the utility model provides the following technical solution: an automatic mixing device, including a machine table, and a heating feeding box for feeding candy raw materials and a mixing box for vacuum stirring the candy raw materials, which are arranged at the end of the machine table. Inside the heating feeding box, there is a feeding copper tube for communicating and feeding into the mixing box. The bottom of the feeding copper tube penetrates to the bottom end of the machine table and is connected with a feeding pump for inputting raw materials into the feeding copper tube. Inside the mixing box, there is a mixing rotating shaft for mixing and scraping the raw materials. At the top end outside the mixing box, there is a servo motor for driving the mixing rotating shaft to rotate. The bottom of the mixing box is penetrated and communicated through a material pipe with a screw centrifugal discharging pump for discharging and outputting the mixed materials. Between the heating feeding box and the mixing box, there is a vacuum pump for evacuating and maintaining the internal vacuum state.

[0007] Preferably, a heating copper plate is embedded in a circle on the inner wall of the heating feeding box, and the input electrode of the heating copper plate is connected with a control heater arranged on one side outside the heating feeding box, so as to heat the incoming candy raw materials during transportation, and keep the candy raw materials with a certain fluidity.

[0008] Preferably, the output end of the feeding pump is connected with a feeding pipe fitting, and the feeding pipe fitting penetrates and is connected to the input end of the feeding copper tube and is connected with a control proportional valve, so that the candy raw materials during transportation can be input into the mixing box in a certain amount during the process of being transported to the mixing box, making the mixing more uniform.

[0009] Preferably, the output end of the feeding copper tube is connected with a vacuum material pipe, and a back pressure valve is connected to the vacuum material pipe, and the vacuum material pipe is connected to the top end of the mixing box, so that the inside of the pipeline can always maintain a vacuum during the transportation of the raw materials, and the raw materials can maintain better quality.

[0010] Preferably, one end of the vacuum pump is connected with a vacuum pipe fitting, and one end of the vacuum pipe fitting is connected to the vacuum material pipe and is equipped with a vacuum control valve, which can control the vacuum pressure inside the mixing box and the pipeline, reduce the inflow of air, and make the raw materials mix more evenly without bubbles.

[0011] Preferably, mixing rods are evenly arranged on the mixing rotating shaft, and the mixing rods are provided with a U-shaped structure and a blanking cleaning scraper attached to the inner wall of the mixing box. The bottom of the mixing box is penetrated and connected with a discharging pipe fitting connected to the input end of the screw centrifugal discharging pump, so as to discharge and output the mixed candy raw materials.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: In this automatic mixing device, through the cooperation of the mixing rotating shaft on the mixing tank, the feeding and cleaning scraper that is U-shaped and attached to the inner wall of the mixing tank, the servo motor, and the spiral centrifugal discharging pump, after the candy raw materials are vacuum-heated and transported into the mixing tank, the servo motor drives the feeding and cleaning scraper and the mixing rod to rotate synchronously by using the mixing rotating shaft. At the same time, in the vacuum mixing tank, the mixing rod can prevent air bubbles from being generated in the stirred and mixed candy raw materials, making the candy raw materials more evenly mixed. Moreover, the feeding and cleaning scraper can scrape and clean the residual candy raw materials generated on the inner wall in a timely manner, avoiding the problem that the candy raw materials adhere to the inner wall and are difficult to clean after drying during the feeding process. Furthermore, after the mixing tank is used, it can be simply rinsed with clean water to be cleaned thoroughly.

[0013] Through the coordinated use of the feeding copper tubes on the heating feeding tank, the heating copper plates arranged on the inner wall, the control proportional valve, the control heater, and the feeding pump, heat is generated by heating the copper plates. During the production of candies, other raw materials of the candies may need to be heated to a specific temperature before mixing to facilitate better mixing in the mixing tank after vacuum transportation or to achieve ideal physical properties. The heat is transferred to the candy raw materials through heat conduction in the tubes. When the mixture flows through the feeding copper tubes, the flow characteristics in the feeding pipes can be utilized to increase the fluid shear and turbulence of the mixture, thereby helping the candy raw materials to mix different components more evenly.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: an automatic mixing device, including a machine table 1, and a heating feeding box 2 for feeding candy raw materials and a mixing box 3 for vacuum stirring the candy raw materials arranged at the end of the machine table 1. The feeding structure in the heating feeding box 2 and the mixing box 3 can be used to add an appropriate amount of raw materials for mixing and stirring. A feeding copper tube 4 communicating with the mixing box 3 is arranged inside the heating feeding box 2 to control and adjust the flow rate of the fluid in the system, which helps to accurately control the flow rate of each raw material during the mixing process, thereby ensuring the consistency and accuracy of the candy formula. The bottom of the feeding copper tube 4 penetrates to the bottom end of the machine table 1 and is connected with a feeding pump 5 for inputting raw materials into the feeding copper tube 4, realizing the automatic counting of candy raw materials into the mixing box 3 for automatic mixing. A mixing rotating shaft 6 for mixing and scraping and cleaning the raw materials is rotatably arranged in the mixing box 3, driving the feeding and cleaning scraping plate 19 to rotate to clean the residues on the inner wall.

[0020] A servo motor 7 for driving the mixing rotating shaft 6 to rotate is arranged at the outer top end of the feeding and mixing box 3, driving the mixing rotating shaft 6 to rotate. The bottom of the mixing box 3 is penetrated and communicated with a screw centrifugal discharging pump 8 for discharging and outputting the mixed materials, which can effectively transport viscous or granular candy raw materials, ensure the smooth flow of the raw materials in the mixing system, and at the same time can discharge the materials evenly, ensuring that the raw materials enter the mixer at a consistent speed and flow rate, thereby improving the mixing uniformity. A vacuum pump 9 for evacuating and maintaining the internal vacuum state is arranged between the heating feeding box 2 and the mixing box 3, which can extract air bubbles from the mixture, prevent the air bubbles from affecting the texture and uniformity of the candy during the mixing process, and at the same time extract air bubbles from the mixture.

[0021] A heating copper plate 10 is embedded in the inner wall of the heating feeding box 2 in a circle. It has good heat conduction and the effect of a heating block, realizing the heating during the conveying of candy raw materials. The input electrode of the heating copper plate 10 is connected to a control heater 11 arranged on the outer side of the heating feeding box 2 to control the heating operation of the heating copper plate 10. The output end of the feeding pump 5 is connected to a feeding pipe fitting 12, which can convey the candy raw materials into the feeding copper tube 4. The feeding pipe fitting 12 penetrates and is connected to the input end of the feeding copper tube 4 and is connected with a control proportional valve 13 to accurately control the flow rate of each raw material, ensuring that each component is added to the mixture according to the set ratio. The output end of the feeding copper tube 4 is connected to a vacuum pipe 14 to realize the vacuum pumping treatment of the pipeline and the mixing tank 3. A back pressure valve 15 is connected to the vacuum pipe 14 to prevent uneven mixing of the mixture or equipment failure caused by pressure fluctuations. During the mixing process, a stable pressure is relatively important for ensuring the uniform mixing and accurate proportioning of the candy raw materials. The vacuum pipe 14 is connected to the top of the mixing tank 3 for the vacuum pumping treatment of the mixing tank 3.

[0022] One end of the vacuum pump 9 is connected to a vacuum pipe fitting 16, and one end of the vacuum pipe fitting 16 is connected to the vacuum pipe 14 and is equipped with a vacuum control valve 17. After the mixing tank 3 is evacuated, the vacuum control valve 17 is used for sealing to avoid the inflow of air. Mixing rods 18 are evenly arranged on the mixing rotating shaft 6, and the mixing rods 18 are provided with a U-shaped structure and a blanking cleaning scraper 19 that fits on the inner wall of the mixing tank 3, which can scrape and clean the upper, lower, left, and right sides of the inner wall of the mixing tank 3 comprehensively, reducing the occurrence of residues. The bottom of the mixing tank 3 is penetrated and connected to a discharge pipe fitting 20 connected to the input end of the screw centrifugal discharge pump 8 to realize the discharge output of the mixed candy raw materials through the discharge pipe fitting 20.

[0023] Specifically, during use, first connect the input pipe of the feeding pump 5 to the output end of an external candy storage tank. At this time, all the valve bodies of the device are in the closed state, and only the vacuum control valve 17 is in the open state. The vacuum pump 9 operates to extract air from the mixing tank 3 and all the pipelines to make them in a vacuum state, which can suck away the bubbles from the mixture and prevent the bubbles from affecting the texture and uniformity of the candy during the mixing process. Subsequently, the feeding pump 5 operates to convey the candy raw materials to the feeding copper tube 4 through the feeding pipe fittings 12. Before that, the control proportional valve 13 is opened, and the control proportional valve 13 precisely controls the flow rate of each raw material to ensure that each component is added to the mixing tank 3 according to the set ratio. Moreover, the candy raw materials enter the heating feeding tank 2, and the control heater 11 is used to heat the heating copper plate 10 to generate heat for performing a fluidity heating treatment on the candy raw materials in the feeding copper tube 4, enabling the other raw materials of the candy to reach a specific temperature after heating before mixing, so as to be better mixed or achieve ideal physical properties when vacuum-transported to the mixing tank 3. Subsequently, the heated candy raw materials are vacuum-transported to the inside of the mixing tank 3, and the servo motor 7 operates to drive the mixing rotating shaft 6 to rotate. The mixing rotating shaft 6 drives the mixing rod 18 and the blanking cleaning scraper 19 to rotate in the mixing tank 3 to mix the candy raw materials, enabling the candy raw materials to be mixed more evenly. Additionally, the blanking cleaning scraper 19 can timely scrape and clean the residual candy raw materials generated on the inner wall to avoid the problem that the candy raw materials adhere to the inner wall and are difficult to clean after drying during the blanking process. Finally, the screw centrifugal discharge pump 8 operates to extract and output the mixed candy raw materials in the mixing tank 3 through the discharge pipe fittings 20, and the screw centrifugal discharge pump 8 can effectively transport viscous or granular candy raw materials to ensure the smooth flow of the raw materials in the mixing system.
