Description

Technical Field

[0001] This utility model relates to the field of candy production technology, specifically to a mixer for manufacturing compressed candy. Background Technology

[0002] Compressed candy is a solid candy made primarily from sugar or syrup, with or without other excipients, through processes such as ingredient preparation, granulation, drying, and tableting. It features diverse tastes, convenience of consumption and portability, and a variety of shapes and colors. Various nutritional fortifiers and flavorings can be added; common examples include vitamin C compressed candy and probiotic compressed candy.

[0003] In the mixing process of compressed candy production, although mainstream equipment such as double-helix conical mixers and planetary mixing tanks are equipped with adjustable-angle scraper devices, the problem of material accumulation in their mixing chambers still requires close attention. Due to differences in material flowability, stagnant zones easily form at the top and bottom of the equipment, especially when processing materials with poor flowability such as dietary fiber and micronized silica gel. The shearing force generated by the rotating impeller blades cannot completely cover the top and bottom areas of the equipment. When the material has an uneven particle size distribution or contains easily agglomerated components, the interaction between gravity settling and mechanical motion leads to local density gradients, forming a stubborn layer of accumulated material at the connection between the equipment head and the cylinder. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a mixer for manufacturing compressed candy that solves the problem of material accumulation on the upper and lower sides of the equipment caused by the difference in material flowability of compressed candy.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a mixer for manufacturing compressed candy, comprising:

[0006] The mixing tank has a detachable lid on top, several legs on the bottom, and a discharge pipe at the center of the bottom surface, with a control valve on the discharge pipe.

[0007] The main mixing mechanism includes a spiral stirring rod and a scraper. The spiral stirring rod is rotatably connected to the bottom of the tank cover and is driven to rotate by a motor fixed on the tank cover. The scraper is fixed to the lower end of the spiral stirring rod and can rotate with it. The scraper is set to fit against the bottom surface of the mixing tank.

[0008] The auxiliary mixing mechanism has two parts, one on the tank cover and the other at the lower end of the mixing tank. Each part includes a guide ring and an air inlet pipe. Several jet pipes are evenly spaced on the guide ring and face the inside of the mixing tank. The air inlet pipe is fixed on the guide ring and connected to an external air supply device.

[0009] Furthermore, the edge of the can lid is connected to the upper end of the side wall of the mixing tank by a number of fixing buckles, which are equidistantly arranged along the side wall of the mixing tank.

[0010] Furthermore, an observation window is provided on the side wall of the mixing tank.

[0011] Furthermore, the diameter of the spiral stirring rod is matched with the inner diameter of the mixing tank.

[0012] Furthermore, the lower end of the mixing tank is a cone shape with a downward convex center, and the scraper is a triangular plate that matches the lower end of the mixing tank. Its length matches the inner diameter of the lower end of the mixing tank, and several scrapers are equidistantly arranged around the central axis of the spiral stirring rod.

[0013] Furthermore, each air guide ring has two symmetrical air inlet pipes. The air guide ring of the auxiliary mixing mechanism on the can lid is fixed above the can lid, and the air inlet pipe is located above the air guide ring. The air guide ring of the auxiliary mixing mechanism inside the mixing tank is embedded in the side wall of the mixing tank, and the air inlet pipe is located on both sides of the air guide ring, with the other end of the air inlet pipe extending out of the mixing tank.

[0014] Compared with existing technologies, the advantages of this invention are as follows: In the main mixing mechanism, the spiral stirring rod is driven by a motor to rotate, which can fully mix the materials. The spiral stirring rod, with a diameter matching the inner diameter of the mixing tank, can reduce dead zones in the mixing process. The scraper, whose lower end is attached to the bottom surface of the mixing tank, can scrape up the accumulated material at the bottom and participate in the mixing during rotation. The lower end of the mixing tank is a cone shape with a downward convex center, which, together with the triangular scraper whose length matches the inner diameter of the lower end of the mixing tank, can better handle the accumulated material at the bottom and prevent material residue.

[0015] In the auxiliary mixing mechanism, the air guide ring and jet pipe located on the tank cover and at the lower end of the mixing tank can inject gas into the mixing tank. The injection of gas can drive the movement of materials on the upper and lower sides, further solving the problem of material accumulation caused by differences in material flowability. The symmetrically arranged air inlet pipes ensure uniform gas injection, enhance the auxiliary mixing effect, make the materials mix more thoroughly, effectively avoid the occurrence of material accumulation on the upper and lower sides of the equipment, and improve mixing efficiency and quality.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 2 A mixing machine for manufacturing compressed candy includes: a mixing tank 1, with a detachable lid 2 on the top. The edge of the lid 2 is connected to the upper end of the side wall of the mixing tank 1 by a plurality of fixing buckles 12. The fixing buckles 12 are equidistantly arranged along the side wall of the mixing tank 1, which facilitates the disassembly and installation of the lid 2, makes it convenient to clean and maintain the inside of the mixing tank 1, and ensures the stability of the connection.

[0024] Combined with appendix Figure 1 Appendix Figure 2 The mixing tank 1 has several support legs 3 at the bottom and a discharge pipe 4 at the center of the bottom surface. The discharge pipe 4 is equipped with a control valve 5. The side wall of the mixing tank 1 is equipped with an observation window 13 to facilitate observation of the mixing status of the materials in the mixing tank 1, timely adjustment of mixing parameters, and improvement of work efficiency.

[0025] Combined with appendix Figure 4 The main mixing mechanism includes a spiral stirring rod 6 and a scraper 7. The spiral stirring rod 6 is rotatably connected to the bottom of the tank cover 2 and is driven to rotate by a motor 8 fixed on the tank cover 2. The diameter of the spiral stirring rod 6 matches the inner diameter of the mixing tank 1, so that the spiral stirring rod 6 can fully stir the material in the mixing tank 1 when rotating, reduce the stirring dead corners, and ensure the uniformity of the mixing effect.

[0026] Combined with appendix Figure 4 The scraper 7 is fixedly mounted on the lower end of the spiral stirring rod 6 and can rotate with it. The scraper 7 is set in close contact with the inner bottom surface of the mixing tank 1. The lower end of the mixing tank 1 is a cone shape with the center protruding downwards. The scraper 7 is a triangular plate that matches the lower end of the mixing tank 1, and its length matches the inner diameter of the lower end of the mixing tank 1. Several scrapers 7 are equidistantly arranged around the central axis of the spiral stirring rod 6, which can better scrape up and stir the material at the bottom of the mixing tank 1, prevent material residue, and improve the utilization rate of the material.

[0027] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5The auxiliary mixing mechanism comprises two parts, one located on the tank cover 2 and the other at the lower end of the mixing tank 1. Each part includes a guide ring 9 and an inlet pipe 10. The guide ring 9 has several jet pipes 11 evenly spaced, facing inwards from the mixing tank 1. The inlet pipe 10 is fixedly mounted on the guide ring 9 and connected to an external gas supply device. Each guide ring 9 has two symmetrically arranged inlet pipes 10. The guide ring 9 of the auxiliary mixing mechanism on the tank cover 2 is fixed above the tank cover 2, and the inlet pipes 10 are located above the guide ring 9. The guide ring 9 of the auxiliary mixing mechanism inside the mixing tank 1 is embedded in the side wall of the mixing tank 1, and the inlet pipes 10 are located on both sides of the guide ring 9, with the other end of the inlet pipe 1 extending out of the mixing tank 1. This ensures that the gas is evenly injected into the mixing tank 1, enhancing the auxiliary mixing effect and making the materials more thoroughly mixed.

[0028] The specific implementation method of this utility model is as follows: First, open the lid 2 on the top of the mixing tank 1 by using the fixing buckle 12, pour the compressed candy material to be mixed into the mixing tank 1, and then close the lid 2 and use the fixing buckle 12 to firmly fasten it to the upper side wall of the mixing tank 1.

[0029] Next, connect the mixer to an external power source and start the motor 8 fixed on the tank cover 2. The motor 8 drives the spiral stirring rod 6 to rotate. The diameter of the spiral stirring rod 6 matches the inner diameter of the mixing tank 1, which can fully mix the materials. At the same time, the scraper 7 fixed to the lower end of the spiral stirring rod 6 rotates accordingly. Since the scraper 7 is set in close contact with the inner bottom surface of the mixing tank 1, and the lower end of the mixing tank 1 is a cone shape with the center convex downward, the scraper 7 is a matching triangular plate, which can effectively scrape up the accumulated material at the bottom of the mixing tank 1, so that the material participates in full mixing.

[0030] During the mixing process, the air inlet pipe 10, connected to the external air supply equipment, supplies air to the air guide ring 9. The air jet pipes 11, evenly distributed on the air guide ring 9, spray air into the mixing tank 1. The auxiliary mixing mechanism, located on the tank cover 2 and at the lower end of the mixing tank 1, works in conjunction to blow material from areas where mixing is difficult, further promoting uniform mixing. Operators can observe the mixing process through the observation window 13 on the side wall of the mixing tank 1.

[0031] Once mixing is complete, open the control valve 5 on the discharge pipe 4, and the mixed material will be discharged from the discharge pipe 4.
