Spray drying technology, with its advantages of rapid drying and high product quality, is widely used in starch sugar production.

[0003] Current spray drying equipment for starch sugar production lacks effective stirring of the starch sugar solution, leading to solute precipitation and uneven concentration during solution settling. This results in inconsistent droplet sizes after atomization, causing significant differences in the moisture content of the dried starch sugar particles, affecting product purity and quality stability. Traditional collection devices struggle to achieve automated discharge control, requiring frequent manual intervention. This not only reduces production efficiency but also increases the risk of material contact with the external environment, easily causing dust pollution and material accumulation inside the equipment, shortening its lifespan. Therefore, a spray drying device for starch sugar production is proposed to address these problems. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a spray drying device for starch sugar production, including a mounting frame 1, a stirring assembly mounted on the top of the mounting frame 1, a device body 2 fixedly connected to the middle of the mounting frame 1, and a conveying assembly mounted on the bottom of the device body 2; the stirring assembly includes a tank 5, which is fixedly connected to the top of the device body 2, a second drive motor 15 is fixedly connected to the top of the tank 5, a rotating shaft 16 is fixedly connected to the output end of the second drive motor 15, and stirring blades 17 are fixedly connected to the outside of the rotating shaft 16. The second drive motor 15 drives the rotating shaft 16 to rotate, and the stirring blades 17 outside the rotating shaft 16 rotate accordingly, causing the solution to form a circulating flow, eliminating concentration gradients and local precipitation, and ensuring that the solution remains uniform before being transported to the atomizer 3 through the infusion pipe 4. A heat exchanger 18 is fixedly connected to the middle of the mounting frame 1. A display 13 is fixedly connected to the outside of the heat exchanger 18. The temperature of the heat exchanger 18 is adjusted through the display 13. The heat exchanger 18 heats the air to the set temperature. The hot air comes into contact with the droplets inside the device body 2. The droplets quickly evaporate the moisture to form solid starch sugar granules. A liquid infusion pipe 4 is fixedly connected to the middle of the mounting frame 1. An atomizer 3 is fixedly connected to the middle of the liquid infusion pipe 4. The other end of the liquid infusion pipe 4 is fixedly connected to the middle of the tank body 5. A connecting pipe 11 is fixedly connected to the middle of the mounting frame 1. An air pump 12 is fixedly connected to the middle of the connecting pipe 11. A dust collection box 9 is fixedly connected to the end of the connecting pipe 11. A drawer 10 is slidably connected to the middle of the dust collection box 9. If fine dust is generated during atomization, it can be recovered through the air pump 12 and the dust collection box 9 to reduce raw material waste and meet environmental protection and safe production requirements. A motor housing 6 is fixedly connected to the top of the tank body 5. The motor housing 6 is fixedly connected to the outside of the drive motor 15. A water pump 14 is fixedly connected to the middle of the infusion tube 4. The starch sugar solution delivered through the infusion tube 4 enters the atomizer 3 under the pressure of the water pump 14. The atomizer 3 breaks the liquid into micron-sized droplets, greatly increasing the surface area of ​​the liquid and creating conditions for subsequent rapid drying. The atomized droplets have a uniform particle size distribution, ensuring the consistency of the starch sugar particles after drying.

[0034] Reference Figure 1 , Figure 2 and Figure 4The conveying assembly includes a housing 7, which is fixedly connected to the bottom of the mounting frame 1. A drive motor 8 is fixedly connected to the outside of the housing 7, and a spiral conveyor blade 22 is fixedly connected to the output end of the drive motor 8. A pipe 19 is fixedly connected to the middle of the housing 7, and a valve body 20 is installed in the middle of the pipe 19. A placement box 21 is placed at the bottom of the pipe 19. The drive motor 8 drives the spiral conveyor blade 22 to rotate, pushing the dried starch sugar granules from the bottom of the device body 2 to the pipe 19. This achieves continuous and stable material conveying, avoiding particle accumulation or blockage. The enclosed housing 7 prevents dust from spilling out, meeting the hygiene requirements of food production. By adjusting the valve opening, the discharge speed can be precisely controlled to adapt to different production capacity needs.

[0035] Working principle: The drive motor 15 drives the rotating shaft 16 and stirring blade 17 to rotate, which fully stirs the starch sugar solution in the tank 5 to ensure uniform concentration and avoid sedimentation or stratification. The water pump 14 delivers the stirred solution to the atomizer 3 through the delivery pipe 4. The atomizer 3 disperses the solution into fine droplets, greatly increasing the evaporation surface area. The heat exchanger 18 heats the air to the set temperature. The hot air comes into contact with the droplets in the main body 2 of the device, and the droplets quickly evaporate the moisture to form solid starch sugar particles.

[0036] The dried starch sugar granules fall to the bottom of the device body 2. The drive motor 8 drives the spiral conveyor blade 22 to rotate, pushing the granules to the pipe 19. The discharge speed of the starch sugar granules is controlled by adjusting the opening and closing degree of the valve body 20, and finally they fall into the placement box 21 for collection.

[0037] The air pump 12 generates negative pressure through the connecting pipe 11, which sucks the dust generated during the drying process into the dust collection box 9. The drawer 10 can be pulled out for cleaning periodically, achieving environmentally friendly production.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
