[0025] 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.

[0026] Example 1 Please see Figures 1-5 The present invention provides a technical solution: a spray drying device for plant-based milk powder, including a drying cylinder 1, with a cover plate 2 at the top of the drying cylinder 1; an atomizer 3 is installed on the cover plate 2, and a feed pipe 31 is connected to the atomizer 3. The feed pipe 31 is used to connect to an external liquid supply device using existing technology, including components such as a storage tank and a pump, so as to introduce liquid into the atomizer 3 and realize the atomizer 3 spraying material.

[0027] A support spring 81 is installed inside the drying cylinder 1, and the top of the support spring 81 is fixedly connected to the inner wall of the drying cylinder 1. Multiple annular airbags 8 are fixedly connected to the support spring 81. The multiple annular airbags 8 are arranged at intervals from top to bottom and are all located inside the support spring 81. The annular airbags 8 can be made of materials such as silicone. A cylindrical plate 82 is connected between each pair of adjacent annular airbags 8. The bottom annular airbag 8 is connected to a material collecting assembly 6. At the same time, the top of the top annular airbag 8 is fixedly connected to the bottom of the cover plate 2.

[0028] The drying cylinder 1 is provided with an air intake assembly 4, which includes an air intake hose 41. The drying cylinder 1 is provided with a first through hole 11, through which the air intake hose 41 passes. The diameter of the first through hole 11 is larger than the outer diameter of the air intake hose 41, and one end of the air intake hose 41 passes through the uppermost cylindrical plate 82, and the air intake hose 41 is fixedly connected to the cylindrical plate 82. The air intake hose 41 is used to connect to an external air source, thereby introducing gas into the cylindrical plate 82 connected to the air intake hose 41. After the air intake hose 41 is connected to the external air source, the air intake hose 41 is in a relaxed and bent state.

[0029] The material collection assembly 6 includes a material collection hopper 61, which is connected to the bottom of the lowest annular airbag 8. The bottom of the material collection hopper 61 is connected to a discharge hose 62, which is used to connect to an external collection device such as a collection box or collection tank. However, after the discharge hose 62 is connected to the external collection device, the discharge hose 62 is in a bent and slack state.

[0030] The drying cylinder 1 is also equipped with an exhaust assembly 5, which is used to exhaust gas. The exhaust assembly 5 includes an exhaust canister 51 fixed on the outer wall of the drying cylinder 1. A gas guide hose 52 is connected between the bottom of the exhaust canister 51 and the lowermost cylindrical plate 82. The gas guide hose 52 is in a relaxed and bent state. At the same time, the drying cylinder 1 is provided with a second through hole 14. The diameter of the second through hole 14 is larger than the outer diameter of the gas guide hose 52. In addition, an exhaust pipe 53 is connected to the top of the exhaust canister 51. A filter screen 521 is fixedly connected inside the end of the gas guide hose 52 that connects to the cylindrical plate 82.

[0031] A connector 9 is provided at the bottom end of the support spring 81, and a disturbance component 7 is also provided on the drying cylinder 1. The disturbance component 7 is used to disturb the connector 9. The connector 9 includes a connecting block 91 fixed at the bottom end of the support spring 81, a connecting plate 92 is provided on the connecting block 91, and an opening 12 is provided on the drying cylinder 1. The connecting plate 92 passes through the opening 12.

[0032] The disturbance component 7 includes a support 71 fixed on the outer wall of the drying cylinder 1, a rotating shaft 73 rotatably mounted on the support 71, and the rotating shaft 73 being movably connected to the support 71 via bearings; a disturbance block 74 is fixedly mounted on the outside of the rotating shaft 73, and the disturbance block 74 has a fan-shaped structure; a drive motor 72 is mounted on the support 71, and the output shaft of the drive motor 72 is fixed to one end of the two rotating shafts 73, and the output shaft of the drive motor 72 is coaxial with the rotating shafts 73; in addition, the disturbance block 74 can be made of materials such as silicone or rubber.

[0033] The drive motor 72 drives the rotating shaft 73 to rotate. When the disturbance block 74 moves from directly below the axis of the rotating shaft 73 to directly above the axis of the rotating shaft 73, the disturbance block 74 causes the connecting plate 92 to move upward, which in turn causes the spring to compress. When the disturbance block 74 moves from directly above the axis of the rotating shaft 73 to directly below the axis of the rotating shaft 73, the connecting plate 92 can move downward due to gravity and the support spring 81. When the connecting plate 92 contacts the rotating shaft 73, the connecting plate 92 is blocked by the rotating shaft 73. Therefore, the rotating shaft 73 drives the disturbance plate to rotate continuously, which can disturb the connecting plate 92, allowing the connecting plate 92 to move up and down. This further causes the support spring 81 to deform continuously. The support spring 81 is connected to the annular airbag 8, which causes the annular airbag 8 to deform. The cylindrical plate 82 is set between two adjacent annular airbags 8. The deformation of the annular airbag 8 can cause the cylindrical plate 82 to move. Therefore, the rotating disturbance block 74 can disturb the annular airbag 8 and the cylindrical plate 82.

[0034] In this embodiment, liquid material is introduced into the atomizer 3 through the feed pipe 31. The liquid material is then sprayed into the area enclosed by multiple annular airbags 8 and multiple cylindrical plates 82 through the atomizer 3. At the same time, airflow is introduced into this area through the air inlet hose 41, which can be either cold or hot airflow as needed. The drive motor 72 drives the rotating shaft 73 to rotate, thereby agitating the connecting plate 92 through the agitator block 74, and further agitating the annular airbags 8 and cylindrical plates 82. This helps to remove the milk powder adhering to the inner walls of the annular airbags 8 and cylindrical plates 82, thereby reducing or preventing the accumulation of a thick layer of milk residue on the inner walls of the annular airbags 8 and cylindrical plates 82. The material dried by the airflow falls into the collection hopper 61 for collection and can be discharged through the discharge hose 62 for convenient subsequent collection. Since the collection hopper 61 is connected to the annular airbags 8, the agitation of the annular airbags 8 also agitates the collection hopper 61, which also reduces or prevents the accumulation of a thick layer of milk residue on the inner wall of the collection hopper 61.

[0035] Meanwhile, the airflow in the drying cylinder 1 enters the exhaust tank 51 through the air guide hose 52, and can be further discharged through the exhaust pipe 53. Since a filter screen 521 is installed inside the air guide hose 52, the filter screen 521 is used to intercept the material, which helps to prevent the dried milk powder from being discharged through the exhaust pipe 53.

[0036] Example 2 See again Figure 1 , Figure 2 Based on Example 1, this embodiment includes an activated carbon filter element 54 installed in the exhaust canister 51 to remove odors from the airflow. The airflow is then discharged from the exhaust pipe 53 after the odors have been removed.

[0037] Example 3 Please see Figure 1 and Figure 6 Based on Embodiment 2, this embodiment has a support ring 13 fixedly sleeved on the outside of the drying cylinder 1. The support ring 13 is close to the bottom end of the drying cylinder 1 and has multiple mounting holes 131.

[0038] By providing a support ring 13 and mounting holes 131, the support ring 13 is easily installed and fixed, thereby facilitating the fixation of the entire atomizing drying device.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
