Abstract

Technical Field
[0001] This utility model relates to the field of food processing equipment technology, and in particular to a mixing and stirring device for the production of pomegranate seasoning ingredients. Background Technology
[0002] Pomegranate flavoring ingredients (such as a mixture of pomegranate juice, pomegranate seed extract, sugar, and additives) are widely used in the food processing industry, including beverages and jams, due to their rich content of polyphenols and vitamins. Mixing and stirring are key processes in their production, requiring not only uniform mixing of the raw materials but also appropriate heating according to process requirements (some processes require 40-60℃ to promote the dissolution of components).
[0003] However, existing mixing devices for pomegranate seasoning ingredients have significant shortcomings. On the one hand, the mixing uniformity is poor. The structure of traditional single-shaft mixing paddles easily leads to the separation of raw materials. In particular, when pomegranate seeds are mixed with liquid components, sedimentation easily occurs due to density differences, resulting in a uniformity of less than 10%, which directly affects the consistency of the taste of the seasoned product. On the other hand, the temperature control accuracy is low. Using external open flame heating or a single-layer heating jacket not only results in slow heating but also temperature fluctuations of ±5℃ or more. Excessive temperature can easily cause the oxidation and loss of active ingredients such as polyphenols in pomegranates, reducing the nutritional value of the raw materials. In addition, cleaning is difficult. Due to the strong viscosity of the raw materials, they easily adhere to the walls of the mixing tank, forming residues. Traditional devices lack a targeted scraper structure, requiring disassembly of the equipment for cleaning, which significantly increases labor costs and operation time.
[0004] Therefore, a mixing and stirring device for the production of pomegranate flavoring ingredients is proposed. Utility Model Content

[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A mixing and stirring device for producing pomegranate flavoring ingredients includes a mixing tank 1, a dual-shaft stirring assembly 2 inside the mixing tank 1, a heating and temperature control structure 3 on the outside of the mixing tank 1, a controller 4 on the right side of the mixing tank 1, and a feeding hopper 5 connected to the top of the mixing tank 1.
[0027] The dual-shaft stirring assembly 2 includes a motor 21 mounted on the top of the stirring tank 1. A main gear 22 is fixedly connected to the output end of the motor 21. The bottom of the main gear 22 penetrates the top of the stirring tank 1. A secondary gear 23 is rotatably connected to both the front and rear sides of the top of the stirring tank 1. The secondary gear 23 meshes with the main gear 22. A stirring shaft 24 is fixedly connected to the bottom of the secondary gear 23. A fixed sleeve 25 is fixedly connected to the outer side of the stirring shaft 24. Stirring paddles 26 are welded to both sides of the fixed sleeve 25. Shearing blades 27 are welded to the top and bottom of the stirring paddles 26. A scraping structure 28 is provided at the bottom of the main gear 22. The outer side of the scraping structure 28 contacts the inner wall of the stirring tank 1.
[0028] In this embodiment: by setting up a mixing tank 1, a dual-shaft stirring assembly 2, a heating and temperature control structure 3, a controller 4, and a feeding hopper 5, during processing, raw materials such as pomegranate juice, pomegranate seed extract, sugar, and additives are fed into the mixing tank 1 through the feeding hopper 5. The controller 4 starts the motor 21 of the dual-shaft stirring assembly 2. The output end of the motor 21 drives the main gear 22 to rotate. The main gear 22 meshes with and drives the secondary gears 23 on the front and rear sides to rotate synchronously in opposite directions, causing the two stirring shafts 24 to rotate in opposite directions. The fixed sleeves 25 on the outer side of the stirring shafts 24 drive the stirring paddles 26 on both sides to rotate. The top and bottom of the stirring paddles 26 rotate in opposite directions. The shearing blades 27 perform staggered shearing on the raw materials, breaking down the layers and dispersing the pomegranate seed particles. At the same time, the scraping structure 28 at the bottom of the main gear 22 rotates with the main gear 22, scraping off the raw material residue on the inner wall of the mixing tank 1 in real time to prevent adhesion and accumulation. During this process, the controller 4 is linked to the heating temperature control structure 3 to stably control the temperature inside the tank at 40-60℃ according to the process requirements, promoting the dissolution of raw materials while preventing the oxidation of active ingredients. The entire process improves the mixing uniformity through the synergistic effect of dual-shaft stirring, shearing dispersion and real-time scraping. Combined with precise temperature control, it achieves efficient and stable mixing and processing of pomegranate seasoning raw materials.
[0029] Specifically, such as Figure 5 As shown, the heating temperature control structure 3 includes an electric heating wire 31 disposed on the outside of the mixing tank 1. The electric heating wire 31 is electrically connected to the controller 4. A heating sleeve 32 is disposed on the outside of the electric heating wire 31. The inner side of the heating sleeve 32 is fixedly connected to the outside of the mixing tank 1.
[0030] Specifically, such as Figure 5 As shown, the outer side of the heating jacket 32 is bonded with insulation cotton 33, and the thickness of the insulation cotton 33 is 5-8cm.
[0031] Specifically, such as Figure 5 As shown, a fixing strap 34 is provided on the outside of the insulation cotton 33. The fixing strap 34 is made of stainless steel cable ties. A temperature sensor 35 is provided at the bottom of the mixing tank 1. The sensing end of the temperature sensor 35 is located inside the mixing tank 1. The temperature sensor 35 is electrically connected to the controller 4.
[0032] In this embodiment: by setting a heating temperature control structure 3, the controller 4 starts the electric heating wire 31 on the outside of the stirring tank 1 according to preset parameters. The heat is conducted to the raw materials inside the stirring tank 1 through the stirring tank 1. The heating sleeve 32 located outside the electric heating wire 31 concentrates its heat on the outside of the stirring tank 1 to ensure the uniformity of heating. The 5-8cm thick heat insulation cotton 33 on the outside of the heating sleeve 32 reduces heat loss. The fixing strap 34 fixed by stainless steel cable ties ensures that the heat insulation cotton 33 is firmly attached. The temperature sensor 35 at the bottom of the stirring tank 1 monitors the internal temperature in real time and feeds it back to the controller 4 to form a closed-loop control, accurately maintaining a process temperature of 40-60℃, which promotes dissolution and avoids oxidation of active ingredients due to high temperature.
[0033] Specifically, such as Figure 4 As shown, the scraping structure 28 includes a main shaft 281 fixedly connected to the bottom of the main gear 22, and a connecting rod 282 fixedly connected to the bottom of the outer side of the main shaft 281.
[0034] Specifically, such as Figure 4 As shown, scrapers 283 are welded to both the front and rear sides of the connecting rod 282. The edge of the scraper 283 is in contact with the inner wall of the mixing tank 1 with a gap of 0.1-0.3mm.
[0035] In this embodiment: by setting up a scraping structure 28, when the main gear 22 rotates, it drives the bottom main shaft 281 to rotate synchronously. The main shaft 281 drives the front and rear scrapers 283 to rotate through the connecting rod 282. The edge of the scraper 283 is in close contact with the inner wall of the mixing tank 1, and scrapes off the sticky raw materials attached to the tank wall in real time during the mixing process, preventing residue accumulation and reducing cleaning processes and raw material waste.
[0036] Specifically, such as Figure 2 As shown, the bottom of the mixing tank 1 is connected to an electric valve 6, which is electrically connected to the controller 4. The bottom of the electric valve 6 is connected to an external drain pipe 7.
[0037] Specifically, such as Figure 2 As shown, a protective cover 8 is provided on the top of the mixing tank 1, and the protective cover 8 is located outside the main gear 22 and the secondary gear 23.
[0038] In this embodiment: by setting an electric valve 6, an external discharge pipe 7 and a protective cover 8, after the mixing is completed, the controller 4 can automatically open the electric valve 6, and the raw material is discharged through the external discharge pipe 7 to realize automated material discharge. The protective cover 8 covers the main gear 22 and the secondary gear 23 to prevent external impurities from entering the meshing area of the main gear 22 and the secondary gear 23, and at the same time avoids personnel from contacting the rotating parts during operation, thus improving the safety of equipment operation.
[0039] Working Principle: In the process of using this mixing and stirring device for pomegranate flavoring production, pomegranate juice, pomegranate seed extract, sugar, and additives are first fed into the mixing tank 1 through the feeding hopper 5. The protective cover 8 on top of the mixing tank 1 covers the main gear 22 and secondary gear 23 to prevent external impurities from entering the gear meshing area and to prevent personnel from contacting the rotating parts during operation. The motor 21 is started by the controller 4. The output end of the motor 21 drives the main gear 22 to rotate. The main gear 22 meshes with and drives the front and rear secondary gears 23 to rotate synchronously in opposite directions, causing the two stirring shafts 24 to rotate in opposite directions. The fixed sleeves 25 on the outer side of the stirring shafts 24 drive the two stirring paddles 26 to rotate. The shearing blades 27 at the top and bottom of the stirring paddles 26 perform staggered shearing of the raw materials, breaking down the layers and dispersing the pomegranate seed particles. When the main gear 22 rotates, it synchronously drives the main shaft 281 at the bottom to rotate. The main shaft 281 drives the front and rear scrapers 283 to rotate through the connecting rod 282. The edges of the scrapers 283 are in contact with the mixing tank. 1. The inner wall is tightly fitted, and the sticky raw materials adhering to the barrel wall are scraped off in real time during the stirring process to prevent residue accumulation. During this process, the controller 4 activates the electric heating wire 31 on the outside of the mixing barrel 1 according to preset parameters. The heat is gathered and evenly conducted to the internal raw materials through the heating sleeve 32 fixedly connected to the outside of the mixing barrel 1. The 5-8cm thick heat insulation cotton 33 on the outside of the heating sleeve 32 reduces heat loss. The fixing strap 34 made of stainless steel cable ties ensures that the heat insulation cotton 33 is firmly attached. The temperature sensor 35 at the bottom of the mixing barrel 1 monitors the internal temperature in real time and feeds it back to the controller 4 to form a closed-loop control, which keeps the temperature stable at 40-60℃, promotes the dissolution of raw materials and prevents the oxidation of active ingredients. After the stirring is completed, the controller 4 automatically opens the electric valve 6, and the mixed raw materials are discharged through the external discharge pipe 7 to realize automated discharge. The whole process achieves efficient and stable pomegranate seasoning raw material mixing and processing through the synergistic effect of dual-shaft stirring, shearing dispersion, real-time scraping and precise temperature control, combined with automated discharge and safety protection.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
