Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yak milk deep processing equipment, and in particular to an automated spray drying device for yak milk deep processing. Background Technology
[0002] In the field of yak milk deep processing, with the continuous increase in market demand for high-quality yak milk products, efficient and high-quality drying technology has become the key to improving product quality and production efficiency. Automated spray drying equipment, as a device capable of rapidly converting liquid yak milk into dry powder, directly affects the quality and yield of yak milk products, as well as the economic benefits of enterprises.
[0003] Currently, common yak milk drying equipment mainly employs a simple hot air drying principle. This type of equipment typically consists of a dryer and a drying tank. The dryer blows hot air into the drying tank, where liquid yak milk is placed at the bottom. Through natural convection, the hot air gradually removes moisture from the surface of the yak milk, thus achieving the drying process. In this process, the contact between the hot air and the yak milk is relatively simple, primarily relying on the natural diffusion of the hot air within the drying tank to transfer heat to the yak milk and promote moisture evaporation.
[0004] However, this traditional drying method has certain problems. Because the hot air relies solely on natural convection to circulate within the drying tank, the contact area and time with the yak milk are limited, making it impossible to fully and quickly remove the moisture from the yak milk. The yak milk remains relatively still at the bottom, making it difficult for its internal moisture to quickly migrate to the surface and be carried away by the hot air, resulting in low overall drying efficiency. This not only increases the production cycle and reduces production efficiency but also increases energy costs to some extent, limiting the company's production capacity and economic benefits. Therefore, an automated spray drying device for the deep processing of yak milk is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automated spray drying device for the deep processing of yak milk, which aims to improve the problem that yak milk is usually dried simply using a dryer, which easily leads to long processing times.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automated spray drying device for deep processing of yak milk includes a drying tank, a feed pipe fixedly connected to the top of the drying tank, a spray head fixedly connected to the inner wall of the feed pipe, and a drying component and a filter component arranged inside the drying tank.
[0008] The drying assembly includes a dryer located inside the drying tank.

[0023] 2. In this utility model, the filter screen is driven by a motor to move in a certain range of up-and-down linear motion, which can block and separate impurities and incompletely dried yak milk. This solves the problem that there will be a certain amount of moisture or impurities inside the yak milk after it is dried into powder, thus improving the quality of yak milk.

[0030] 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.
[0031] Reference Figures 1-3 An embodiment of this utility model is provided: an automated spray drying device for deep processing of yak milk, including a drying tank 1, a feed pipe 5 fixedly connected to the top of the drying tank 1, a spray head 6 fixedly connected to the inner wall of the feed pipe 5, and a drying component and a filter component arranged inside the drying tank 1.
[0032] The drying assembly includes a dryer 8, which is located inside the drying tank 1. A fixing pipe 7 is fixedly connected to the inner wall of the drying tank 1, and the dryer 8 is fixedly connected to the inner wall of the fixing pipe 7. The function of the fixing pipe 7 is to provide stable support for the dryer 8, ensuring its fixation within the drying tank 1 and preventing displacement caused by vibration or airflow during operation, thereby ensuring the normal operation of the drying equipment. A support frame 2 is fixedly connected to the top of the drying tank 1. A motor 3 is fixedly connected inside the support frame 2. A rotating shaft 4 is fixedly connected to the output end of the motor 3. Multiple fixing rings 9 are fixedly connected to the outer wall of the rotating shaft 4. Multiple rotating blades 10 are fixedly connected to the outer wall of each fixing ring 9. A fixing ring 11 is fixedly connected to the outer wall of each rotating blade 10. Multiple rotating blades 12 are fixedly connected to the outer wall of each fixing ring 11. The function of the motor 3 is to provide rotational power to the rotating shaft 4, thereby driving the movement of the multiple rotating blades 10 and 12. These rotating blades, through high-speed rotation, increase the airflow velocity inside the drying tank 1, optimizing the contact area between hot air and yak milk, thereby improving drying efficiency. The function of fixing ring 9 and fixing ring 11 is to ensure stable operation of rotating blades 10 and 12 when the shaft 4 rotates, preventing the blades from falling off or shifting due to excessive centrifugal force, ensuring the smooth operation of the equipment. Multiple support frames 21 are fixedly connected to the outer wall of the drying tank 1. The function of the support frames 21 is to provide additional support for the drying tank 1, ensuring its stability during operation and preventing shaking or tilting during high-speed operation. A discharge valve 22 is fixedly connected to the bottom of the drying tank 1. The function of the discharge valve 22 is to ensure that the dried yak milk powder can be smoothly discharged from the drying tank 1, preventing excessive accumulation of material from affecting subsequent work and ensuring the continuity and efficiency of the entire production process.
[0033] Specifically, in the yak milk drying process, the dryer 8 first converts cold air into hot air and delivers the hot air into the drying tank 1. This process, through precise control of the cold air and heat exchange components, raises the external cold air to a suitable temperature range, providing a stable heat source for the drying process. Next, motor 3 is started, and its output drives shaft 4 to rotate. The rotation of shaft 4 drives rotating blades 10 and 12 to rotate simultaneously. The centrifugal force generated by the rotation of blades 10 and 12 pushes the yak milk accumulated at the bottom of the drying tank 1 outwards, allowing hot air to penetrate smoothly to the surface of the yak milk, thus accelerating moisture evaporation. Blades 10 and 12 not only guide the airflow but also drive rapid airflow inside the drying tank 1 through their high-speed rotation. Because the airflow velocity is increased, the efficiency of air-yak milk contact is greatly enhanced, resulting in more heat energy being transferred to the yak milk, further accelerating moisture evaporation and the drying process. Meanwhile, the rotating blades 10 and 12 effectively prevent caking of yak milk during the drying process, maintain the uniformity and flowability of the material, and ensure the high efficiency and stability of the entire drying process.
[0034] Reference Figure 2 and Figure 4The filtration assembly includes a filter screen 19, located inside the drying tank 1. The filter screen 19 performs preliminary filtration of impurities in the yak milk, ensuring its purity during subsequent drying. A mounting bracket 13 is fixedly connected to one side of the drying tank 1. The mounting bracket 13 provides fixed support for the motor 14, ensuring it does not shift or vibrate during operation. The motor 14 is fixedly connected to the top of the mounting bracket 13, providing power to the rotating shaft 15 and ensuring its stable rotation. The output end of the motor 14 is fixedly connected to the rotating shaft 15, which transmits power from the motor 14 to downstream transmission components, ensuring efficient operation of the entire drive unit. A mounting bracket 20 is fixedly connected to one end of the rotating shaft 15, with one side of the mounting bracket 20 fixedly connected to the outer wall of the drying tank 1. The mounting bracket 20 provides additional support for the rotating shaft 15, ensuring its stability during high-speed rotation and preventing damage or imbalance caused by forces. Multiple transmission plates 16 are fixedly connected to the outer wall of the rotating shaft 15. The function of the transmission plates 16 is to transmit the rotational motion of the rotating shaft 15 to the multiple transmission plates 17. Each transmission plate 16 is rotatably connected to a transmission plate 17. Through its rotational characteristics, the transmission plate 17 further transmits force to the connecting block 18, ensuring that the filter screen 19 can be effectively cleaned. Each transmission plate 17 is rotatably connected to a connecting block 18. The function of the connecting block 18 is to move the filter screen 19 up and down through its connection with the filter screen 19, preventing the pores of the filter screen 19 from being blocked by impurities. The top of the connecting block 18 is fixedly connected to the bottom of the filter screen 19. The movement of the connecting block 18 causes the filter screen 19 to slide on the inner wall of the drying tank 1, preventing impurities from accumulating on the filter screen 19, thereby maintaining filtration efficiency. The filter screen 19 is slidably connected to the inner wall of the drying tank 1. The sliding design of the filter screen 19 prevents impurities from accumulating during the filtration process and maintains stable filtration performance.
[0035] Specifically, in the yak milk filtration process, filter screen 19 is first used to effectively filter impurities from the yak milk. The fine pores of filter screen 19 can effectively remove insoluble impurities from the yak milk, and also provide filtration for subsequent yak milk powder processing. This filtration process is crucial to ensuring the purity of the yak milk in subsequent processing stages. As the filtration operation proceeds, a certain amount of impurities gradually accumulates on filter screen 19, which can cause the mesh to become clogged, thus affecting the filtration effect. To ensure the continuity and efficiency of the filtration process, motor 2 14 is then started. The output end of motor 2 14 drives shaft 2 15 to rotate, and the rotation of shaft 2 15 transmits power to transmission plate 1 16 through a transmission component. The movement of transmission plate 1 16, through its connection with transmission plate 2 17, pushes the connecting block 18 at the top of transmission plate 2 17 to move up and down. The up and down movement of connecting block 18 effectively cleans the surface of filter screen 19, preventing impurities from clogging the pores of filter screen 19, ensuring that filter screen 19 remains unobstructed, thereby improving filtration efficiency.
[0036] Working principle: During the drying process of yak milk, the dryer 8 converts cold air into hot air and transmits it to the inside of the drying tank 1. Then, the motor 3 is started, and the output of the motor 3 drives the rotating shaft 4 to rotate. While rotating, the rotating shaft 4 drives the rotating blades 10 and 12 to rotate. The rotational force of the rotating blades 10 and 12 guides the yak milk accumulated at the bottom to the outside, allowing hot air to enter the surface of the yak milk at the bottom. While rotating, the rotating blades 10 and 12 also accelerate the flow rate of hot air inside the drying tank 1, thereby improving the drying efficiency of yak milk.
[0037] During the yak milk filtration process, filter screen 19 is used to filter out some impurities in the yak milk, and also to filter the yak milk powder for subsequent processing. Then, motor 2 14 is started, and the output end of motor 2 14 drives the rotating shaft 2 15 to rotate. While rotating, the rotating shaft 2 15 pushes the connecting block 18 at the top of the transmission plate 2 17 to move up and down through the transmission plate 1 16, preventing the holes inside the filter screen 19 from being blocked and enhancing the processing effect of the equipment on the yak milk.
[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.
