Abstract
Description
Technical Field
[0001] This utility model relates to the field of food additive production technology, and in particular to a drying device for food additive production. Background Technology
[0002] In the modern food industry, food additives are important components for improving food quality and extending shelf life. Their production process is crucial for food safety and quality control. Drying, as a key step in the production of food additives, not only affects the final quality of the product but also directly relates to production efficiency and cost control. However, existing drying equipment for food additive production has some shortcomings in its structural design, which affects the drying effect.
[0003] Existing drying equipment often neglects the effective discharge of water vapor in its structural design. During the drying process, as moisture evaporates, a large amount of water vapor accumulates inside the equipment. If the water vapor cannot be discharged in time, it will not only prolong the drying time, but may also cause the food additives on the surface to become damp. Secondly, due to the lack of efficient stirring mechanism in existing drying equipment, food additives often accumulate and clump during the drying process. This not only reduces the drying efficiency, but may also cause uneven heating of the food additives. In addition, the internal structure of the equipment is complex with many dead corners, making it difficult to clean thoroughly and prone to bacterial growth. Utility Model Content
[0004] This utility model proposes a drying device for food additive production, which solves the problems of poor water vapor emission, low drying efficiency, and difficult cleaning and maintenance of existing drying devices for food additive production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A drying device for food additive production includes a drying tank. An insulating sleeve is fitted around the outside of the drying tank, and an annular boss is fitted on the upper part of the outer side of the insulating sleeve. An adjustable exhaust port is provided inside the annular boss. An annular baffle is provided at the bottom of the insulating sleeve, and a heating mechanism is provided outside the annular baffle. An annular fixing plate is provided at the top of the insulating sleeve, and an annular cover plate is provided at the top of the annular fixing plate. A residual heat stirring mechanism is provided between the annular cover plate and the inside of the drying tank. Automatically adjustable heat dissipation holes are provided on the outer side of the annular cover plate, and an installation groove is provided inside the annular cover plate. A high-pressure annular water pipe is installed inside the installation groove, and a water inlet pipe is provided at the top of one end of the annular water pipe.
[0007] Preferably, a support frame is provided on the outside of the insulation sleeve, and a discharge hopper is provided at the bottom of the annular baffle inside the support frame, with an electromagnetic valve provided below the discharge hopper.
[0008] Preferably, the annular boss and the interior of the insulation sleeve are provided with an exhaust port that communicates with each other, and an annular slide is provided above the interior of the annular boss. An adjustment plate matching the exhaust port is provided inside the annular slide, and a protruding rod is provided on the top of the adjustment plate.
[0009] Preferably, the heating mechanism includes a steam generator, a connecting pipe, and an air inlet, and the annular baffle is provided with multiple sets of air inlets. The support frame is provided with a steam generator on its side, and the steam generator is connected to the air inlet inside the annular baffle through the connecting pipe to form a heating structure.
[0010] Preferably, the annular fixing plate has a feed inlet on its outer side, and a feed hopper is provided inside the feed inlet. A sliding groove is provided above the inside of the feed hopper, and a matching sealing plate is provided inside the sliding groove in a sliding connection.
[0011] Preferably, the waste heat stirring mechanism includes a stirring shaft, stirring blades, a fixing groove, a scraper, bolts, a heat storage block, and a first drive motor. The annular cover plate and the inside of the drying tank are provided with a stirring shaft. Multiple sets of staggered stirring blades are provided on the outside of the stirring shaft. Fixing grooves are provided on both sides of the stirring blades. Scrapers are installed in the fixing grooves by bolts. Heat storage blocks are provided inside the stirring blades. The top of the annular cover plate is provided with a first drive motor, and the output end of the first drive motor is connected to the stirring shaft.
[0012] Preferably, the annular cover plate has a movable groove inside, and a movable plate matching the heat dissipation hole is provided inside the movable groove. An annular rack is provided on the upper outer side of the movable plate, and a second drive motor is provided on the top of the annular fixed plate. A drive gear is provided at the output end of the second drive motor, and the drive gear is meshed with the annular rack.
[0013] Preferably, the bottom of the annular water pipe is provided with multiple sets of water spray nozzles inside the drying tank.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The drying device for food additive production has automatically adjustable heat dissipation holes on the outer side of the annular cover plate. The second drive motor drives the meshing drive gear and the annular rack, thereby realizing the rotation of the movable plate inside the movable groove and adjusting the size of the heat dissipation holes. A certain number of heat dissipation holes are set on the side of the annular cover plate. These heat dissipation holes can adjust the steam emission rate according to actual needs. In addition, by adjusting the size of the heat dissipation holes, the drying process can be precisely controlled, improving the stability and uniformity of the product.
[0016] 2. The annular cover plate and the interior of the drying tank are equipped with a residual heat stirring mechanism. The stirring shaft and stirring blades are driven by the first drive motor to fully stir and agitate the food additives inside the drying tank. With the addition of the stirring mechanism, the food additives can remain in a loose state during the drying process, avoiding accumulation and clumping. This not only improves drying efficiency but also ensures that the food additives are heated evenly, improving product quality and stability. At the same time, the stirring mechanism can also promote full contact between the food additives and hot air, further shortening the drying time. The heat storage block inside the stirring blades can absorb the residual heat that would otherwise be lost inside the drying tank. Under the rotation of the stirring blades, the food additives undergo secondary exothermic drying. This structure can reduce heat loss during the transfer process, improve overall thermal efficiency, and help improve drying efficiency.
[0017] 3. The installation tank is equipped with a high-pressure ring water pipe, and a water inlet pipe is installed at the top of the ring water pipe at one end. Multiple spray nozzles are installed at the bottom of the ring water pipe. A high-pressure water pump connected to the water inlet pipe is used to clean the inside of the drying tank. At the same time, in conjunction with the scraper installed inside the fixed tank by bolts, the first drive motor drives the agitation, which can prevent food additives from adhering to the inner wall of the equipment, further improving the cleaning effect.

[0026] Reference Figures 1-6 This utility model provides a technical solution: a drying device for food additive production, including a drying tank 1, an insulating sleeve 2 on the outside of the drying tank 1, and an annular boss 3 on the upper outside of the insulating sleeve 2. An adjustable exhaust port 4 is provided inside the annular boss 3. An annular baffle 311 is provided at the bottom of the insulating sleeve 2. A heating mechanism is provided outside the annular baffle 311. An annular fixing plate 5 is provided at the top of the insulating sleeve 2.

[0027] Reference Figure 1 , Figure 4The waste heat stirring mechanism includes a stirring shaft 24, stirring blades 25, a fixing groove 26, a scraper 27, bolts 28, a heat storage block 29, and a first drive motor 30. The stirring shaft 24 is installed inside the annular cover plate 6 and the drying tank 1. Multiple sets of staggered stirring blades 25 are arranged on the outside of the stirring shaft 24, and fixing grooves 26 are provided on both sides of the stirring blades 25. Scrapers 27 are installed inside the fixing grooves 26 by bolts 28. The scrapers 27 can prevent food additives from adhering to the inner wall of the equipment during the drying and stirring process. At the same time, it is also convenient to clean the inside of the drying tank 1. Heat storage blocks 29 are provided inside the stirring blades 25. The first drive motor 30 is installed on the top of the annular cover plate 6, and the output end of the first drive motor 30 is connected to the stirring shaft 24. The stirring blades 25 can continuously turn the food additives during rotation, so that the food additives can fully contact the hot air, improve the drying uniformity, and prevent the food additives from accumulating and clumping, reducing the risk of equipment blockage.
[0028] In specific implementation, when the drying device for food additive production is being cleaned, a high-pressure water pump is first connected to the water inlet pipe 10, and then the inside of the drying tank 1 is rinsed through the high-pressure annular water pipe 9 and the spray nozzle 36. At the same time, the first drive motor 30 is started, which drives the stirring shaft 24 and the stirring blades 25 to stir inside the drying tank 1. Then, the scraper 27 can continuously scrape and wash the residue adhering to the inner wall of the drying tank 1 during rotation, thereby improving the cleaning effect. Finally, the solenoid valve 13 is opened to discharge the cleaning wastewater from the discharge hopper 12. Through the above operations, the cleaning effect is improved, the quality of the food additive drying process is guaranteed, and bacterial growth is avoided.
[0029] Reference Figure 4 , Figure 5 The insulation sleeve 2 is provided with a support frame 11 on the outside, and the bottom of the annular baffle 311 is located inside the support frame 11 and a discharge hopper 12 is provided. The discharge hopper 12 is provided below the discharge hopper 12 and an electromagnetic valve 13 is provided. The annular boss 3 and the insulation sleeve 2 are provided with an exhaust port 4 that communicates with each other. The annular boss 3 is provided with an annular slide 14 on the upper part. The annular slide 14 is provided with an adjustment plate 15 that matches the exhaust port 4. The top of the adjustment plate 15 is provided with a protruding rod 16. The heating mechanism includes a steam generator 17, a connecting pipe 18, and an air inlet 19. The annular baffle 311 is provided with multiple sets of air inlets 19. The support frame 11 is provided with a steam generator 17 on the side. The steam generator 17 is connected to the air inlet 19 inside the annular baffle 311 through the connecting pipe 18 to form a heating structure.
[0030] Reference Figure 2 , Figure 3 , Figure 6An inlet 20 is provided on the outer side of the annular fixed plate 5, and a feeding hopper 21 is provided inside the inlet 20. A sliding groove 22 is provided on the upper part of the feeding hopper 21, and a matching sealing plate 23 is provided inside the sliding groove 22 in a sliding connection. An movable groove 31 is provided inside the annular cover plate 6, and a movable plate 32 matching the heat dissipation hole 7 is provided inside the movable groove 31. An annular rack 33 is provided on the upper part of the outer side of the movable plate 32, and a second drive motor 34 is provided on the top of the annular fixed plate 5. A drive gear 35 is provided at the output end of the second drive motor 34, and the drive gear 35 is meshed with the annular rack 33.
[0031] In practice, when the drying device is in use, the food additive is first poured into the drying tank 1 through the feed inlet 20. Then, the sealing plate 23 is manually slid to close the feed hopper 21. At the same time, the steam generator 17 is started. The steam generator 17 supplies a continuous stream of steam into the insulation sleeve 2 through the connecting pipe 18 and the air inlet 19, thereby rapidly raising the temperature of the drying tank 1. When the temperature is too high, the adjusting plate 15 inside the annular slide 14 is manually rotated through the protruding rod 16 to adjust the size of the exhaust port 4 according to actual needs, thereby dissipating heat from inside the insulation sleeve 2 and achieving cooling inside the drying tank 1. Maintaining a stable temperature helps improve the drying quality of food additives. Next, the first drive motor 30 is started, which drives the stirring shaft 24 and stirring blades 25 to rotate inside the drying tank 1. This allows the stirring blades 25 to continuously tumble the food additives during rotation, ensuring that the food additives come into full contact with the hot air and improving the uniformity of drying. At the same time, the heat storage block 29 absorbs the residual heat that would otherwise be lost inside the drying tank 1, and performs secondary exothermic drying on the food additives under the rotation of the stirring blades 25. Through the above operations, the drying efficiency is improved and the drying time is shortened.
[0032] When a large amount of water vapor accumulates inside the device, the second drive motor 34 is first started. The second drive motor 34 drives the meshing drive gear 35 and the ring rack 33, thereby realizing the rotation of the movable plate 32 inside the movable slot 31 to adjust the size of the heat dissipation hole 7. The heat dissipation hole 7 can adjust the water vapor emission speed according to actual needs. Finally, the solenoid valve 13 is opened to discharge the dried food additive through the discharge hopper 12. Through the above operations, the stability and uniformity of the product are improved, and the drying time is also shortened.
[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
