Description
Technical Field
[0001] This invention relates to the field of mixing and stirring technology in confectionery processing, and more particularly to a mixing and stirring device for confectionery processing. Background Technology
[0002] Candy is loved by consumers for its unique taste and rich flavor. Its preparation process mainly includes raw material mixing and granulation, among which the mixing and stirring of raw materials is the key step to ensure the quality of the final product.
[0003] Traditional confectionery mixing equipment typically employs a single mixing mechanism, generally consisting of a mixing chamber, a mixer, and a drive unit. The U-shaped tubular chamber houses a double-layered, counter-rotating helical ribbon mixer shaft. This structure easily causes materials to rotate in the same direction, reducing the uniformity of mixing the food processing ingredients. During mixing, some materials may also settle to the bottom. Uneven mixing of ingredients can easily lead to poor candy texture and affect product quality.
[0004] A search revealed Chinese patent application CN201820953907.3, which discloses a raw material mixing and stirring device for candy production. The device includes a shell, a feed hopper, a threaded rod, a motor, a first stirring shaft, a second stirring shaft, a transmission belt, a first stirring blade, a second stirring blade, a discharge hopper, a sealing groove, a rubber plug, a positioning groove, fixing bolts, a sealing plate, fixing holes, and a cutting blade. While the raw material mixing and stirring device in the aforementioned document has a stirring function, it is constrained by the shape of the internal cavity and the stirring structure, resulting in stirring dead zones. Although a multi-layer stirring structure is set up, it cannot effectively mix the upper and lower layers of raw materials, especially the raw materials in the bottom stirring dead zones, leading to insufficient mixing and potentially inconsistent product quality.

Detailed Implementation
[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0026] Example 1: A mixing and stirring device for candy processing, such as... Figure 1-6As shown, the device includes a main body, and an internal stirring mechanism and an external stirring mechanism are provided inside the main body. An inner cylinder 19 is provided between the inner stirring mechanism and the outer stirring mechanism. The shape of the inner cylinder 19 is adapted to the inner wall of the device body. The outer stirring mechanism rotates within the annular gap formed between the outer wall of the inner cylinder 19 and the device body. The inner stirring mechanism rotates inside the inner cylinder 19. The inner cylinder 19 is connected to the annular gap through the top opening and the bottom opening; when the inner stirring mechanism and the outer stirring mechanism rotate, the material circulates between the inside and outside of the inner cylinder 19. By setting up internal and external stirring mechanisms, the material can circulate between the inside and outside of the inner cylinder 19 during operation, overcoming the problem of dead zones in traditional stirring devices. This prevents some material from settling to the bottom, thereby achieving better stirring effect and improving product quality.
[0027] For ease of heat treatment; such as Figure 1 , Figure 3 As shown, a heating mechanism is provided at the bottom of the main body of the device; By setting a heating mechanism at the bottom of the main body of the device, the material can be prevented from cooling and solidifying, thus maintaining its fluidity. Furthermore, since the material can circulate between the inside and outside of the inner cylinder 19, the heating mechanism ensures a uniform heating effect on the material while stirring.
[0028] To facilitate the flow of materials; such as Figure 2 , Figure 4 , Figure 6 As shown, the external stirring mechanism includes: Rotating frame 15 is rotatably installed inside the first main body 1; Guide vane 17, the top end of guide vane 17 is fixed to the end of rotating frame 15, multiple guide vanes 17 are arranged in a circumferential distribution, the bottom end of guide vane 17 extends to the outer side of the bottom of inner cylinder 19, the size of guide vane 17 is adapted to the annular gap, and the shape of guide vane 17 is a spiral structure. External stirring control unit, used to control the rotation of rotating frame 15; By setting up structures such as guide vanes 17, the material can be lifted upwards under the guidance of the guide vanes 17 during the mixing process, and finally flow back into the inner cylinder 19 from the top opening of the inner cylinder 19.
[0029] To facilitate the flow of materials; such as Figure 2 , Figure 5 , Figure 6 As shown, the internal stirring mechanism includes: Rotate the main shaft 24, which is rotatably installed inside the first main body 1, with the bottom end of the main shaft 24 extending below the bottom opening of the inner cylinder 19; The stirring impeller 23 is fixed to the bottom of the rotating main shaft 24. Based on the rotation of the stirring impeller 23, the material can be pushed to the outside of the stirring impeller 23. An internal stirring control unit is used to control the rotation of the main rotating shaft 24. By setting up structures such as the stirring impeller 23, the material falling to the bottom can be pushed outward during the mixing process and enter the annular gap so that it can be lifted up by the guide blade 17, thereby forming a circulation and ensuring the mixing effect and uniform heating effect.
[0030] To improve the mixing effect; such as Figure 5 , Figure 6 As shown, a plurality of circumferentially distributed stirring arms 20 are fixed on the side wall of the rotating main shaft 24, and one end of the stirring arm 20 extends to the inner wall of the inner cylinder 19. By setting up the stirring arm 20, the material movement inside the stirring cylinder 19 can be assisted by the rotation of the rotating main shaft 24, thereby improving the stirring effect.
[0031] like Figure 1 , Figure 2 As shown, the main body of the device includes: The first main body 1 has a bowl-shaped structure, and the inner cylinder 19 is located inside the first main body 1. The inner cylinder 19 has an arc-shaped annular structure that is adapted to the inner wall of the first main body 1. The second main body 2 is ring-shaped and is fixed to the top of the first main body 1 to form a constricted neck structure. The third body 8 is fixed to the second body 2; The diameter of the inner cylinder 19 is smaller than the inner diameter of the third body 8; the bottom end of the stirring impeller 23 has an arc-shaped structure that matches the inner side of the first body 1; preferably, the blades of the stirring impeller have an arc-shaped structure when viewed from above, so as to better push the material. With this design, during disassembly and assembly, the guide vane 17 can be installed first, followed by the inner cylinder 19, then the stirring impeller 23 and other structures can be installed, and finally the rotating frame 15 and other structures can be connected to each guide vane 17. This achieves the matching installation of the inner stirring mechanism, the outer stirring mechanism and the inner cylinder 19, avoiding the situation where disassembly and assembly are impossible due to structural shape and size limitations.
[0032] To improve the looping effect; such as Figure 2 , Figure 4 , Figure 6As shown, a guide plate 16 is fixed at the bottom of the second main body 2. Multiple guide plates 16 are disassembled and combined to form an annular structure. After assembly, the bottom surfaces of each guide plate 16 cooperate to form an annular inclined structure. The radius of the annular inclined structure gradually decreases in the vertical upward direction. The guide plate 16 is located inside the first main body 1 and at the top of the annular gap. By setting the guide plate 16, after the guide vane 17 lifts the material, the guide plate 16 can guide the material to flow better into the top opening of the inner cylinder 19, so as to promote the circulation effect.
[0033] For better circulation; such as Figure 2 , Figure 5 , Figure 6 As shown, a limiting plate 25 is integrally provided on the top of the inner cylinder 19, and the limiting plate 25 is recessed into the inner side of the inner cylinder 19. By setting the limiting plate 25, the material can be prevented from moving to the outside of the top opening of the inner cylinder 19 during the stirring process of the stirring arm 20, which plays a certain blocking role.
[0034] To facilitate heating; such as Figure 2 , Figure 3 , Figure 4 As shown, the main body of the device is provided with a cavity 12, which has an annular structure. The heating mechanism includes: Heating base 11, the heating base 11 is installed on the bottom outer wall of the first main body 1; Heating element 18 is disposed in cavity 12 and is electrically connected to heating base 11; A heat transfer rod 21 is fixed to the bottom inner wall of the first main body 1, with one end of the heat transfer rod 21 extending to the heating element 18 and the other end extending into the interior of the first main body 1; a heat transfer sleeve 22 is fixed to the bottom of the inner cylinder 19, and the heat transfer sleeve 22 is detachably installed on the heat transfer rod 21. By setting up a heating mechanism, it can work based on the heating base 11 and heat the inner wall of the first main body 1 through the heating element 18, thereby heating the material inside the first main body 1; since the heat transfer sleeve 22 and heat transfer rod 21 are set up, some of the heat can be more easily conducted to the inner cylinder 19, thereby making the material easier to heat up during the stirring process.
[0035] To control structural rotation; such as Figure 1As shown, the top of the third main body 8 is fixed with a top frame 3, and a mounting base 26 is installed on the top frame 3. The internal stirring control unit includes a first motor 5, which is mounted on the mounting base 26. The rotating main shaft 24 is rotatably mounted on the mounting base 26, and the output end of the first motor 5 is connected to the rotating main shaft 24. The external stirring control unit includes a second motor 4, which is mounted on one side of the mounting base 26. The top of the rotating frame 15 is detachably fixed with a rotating drum 13, which is located outside the rotating main shaft 24. The top of the rotating drum 13 is rotatably mounted inside the mounting base 26. The output end of the second motor 4 is connected to the rotating drum 13 through a helical gear transmission assembly 14.
[0036] The first main body 1 is provided with a top cover 7, one side of which is hinged to the top frame 3. The top frame 3 of the first main body 1 is connected to a pipeline system 6. The bottom of the first main body 1 is provided with a discharge pipe 10, and a control valve is provided on the discharge pipe 10. The bottom of the first main body 1 is provided with a support leg 9 for support.
[0037] Furthermore, in this invention, the cavity 12 can extend from the first body 1 through the second body 2 to the third body 8, or it can be located solely within the first body 1. The heating element 18 can be installed within the cavity 12 or directly installed at the bottom of the first body 1, with additional heat insulation measures such as a heat insulation cover. When the heating element 18 can be installed within the cavity 12, a sealing door for maintenance can be provided on the outer wall of the first body.
