[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this utility model is a spray drying device for rice protein peptides, specifically capable of drying enzymatically hydrolyzed rice protein peptides, including a drying tower body 1; a sealing cover plate 3 is provided above the drying tower body 1, a worm gear 5 is provided inside the sealing cover plate 3, a conveying support sleeve 6 is provided through the middle of the worm gear 5, a transverse airflow pipe 605 for longitudinal airflow conveying is provided outside the conveying support sleeve 6, and a longitudinal airflow pipe 6052 for transverse airflow conveying is provided outside the transverse airflow pipe 605.

[0028] In this embodiment, preferably, a ring-shaped sealing insulating element 4 is installed on the lower outer side of the sealing cover plate 3. The sealing cover plate 3 is connected to the drying tower body 1 by the sealing insulating element 4, which is glued together, so as to keep the drying tower body 1 in a relatively sealed state.

[0029] In this embodiment, preferably, a worm 501 is connected to the right side of the worm wheel 5, and the worm wheel 5 and the conveying support sleeve 6 are fixedly connected through the worm wheel 5.

[0030] The worm gear 5 and the worm 501 are connected by meshing.

[0031] In this embodiment, preferably, the conveying support sleeve 6 and the transverse airflow pipe 605 and the transverse airflow pipe 605 and the longitudinal airflow pipe 6052 are all connected, and the longitudinal airflow pipe 6052 is equidistantly distributed about the center point of the conveying support sleeve 6.

[0032] The lower end of the conveying support sleeve 6 is fixedly connected to a fixed base plate 601. The fixed base plate 601 and the movable base 602 are engaged. The movable base 602 forms a rotating structure on the guide base plate 603 through a built-in bearing.

[0033] In this embodiment, preferably, a rotating seal is provided at the connection between the upper end of the conveying support sleeve 6 and the sealing cover plate 3, and the conveying support sleeve 6 forms a communication structure with the temperature controller 8 through the first connecting pipe 7.

[0034] The temperature controller 8 is connected to the compressor 10 via the second connecting pipe 9.

[0035] In summary, the enzymatically hydrolyzed rice protein peptides are first poured into the drying tower body 1. Then, the conveying support sleeve 6 is connected to the movable base 602 via the fixed base plate 601 fixed at the lower end. The sealing cover 3 is connected to the drying tower body 1 via the sealing insulation part 4 arranged in a ring on the lower outer side to increase the relative sealing effect inside the drying tower body 1. The worm wheel 5 and the worm 501 are connected by meshing, and the conveying support sleeve 6 passes through the middle of the worm wheel 5 and is fixedly connected. When the servo motor 502 is turned on to rotate the worm 501, it can drive the worm wheel 5, which is meshed with the worm 501, to rotate synchronously, so that the worm wheel 5 drives the conveying support sleeve 6 to rotate in a circular motion.

[0036] The outer end of the conveying support sleeve 6 is divided into three equal parts, and the stirring blades 604 are inclined on the left and right. This allows them to reciprocate to scoop up the rice protein peptides. When the conveying support sleeve 6 rotates, it drives the stirring blades 604 to scoop up and turn the rice protein peptides clockwise. The special structure of the stirring blades 604 allows the rice protein peptides to be turned and dried better. Combined with the vertical air blowing of the first airflow atomizing nozzle 6051 and the lateral air blowing of the second airflow atomizing nozzle 6053, the drying effect is improved, and the functional activity of the rice protein peptides is further increased.

[0037] Example 2

[0038] Reference Figure 1 , Figure 2 and Figure 3 The image shows the second embodiment of this utility model, specifically capable of spraying and scraping off rice protein peptides adhering to the inner wall of the drying tower body 1. It includes a first airflow atomizing nozzle 6051 that can blow air vertically on the inner side of the transverse airflow pipe 605, and a second airflow atomizing nozzle 6053 that can blow air laterally on the outer side of the longitudinal airflow pipe 6052.

[0039] In this embodiment, preferably, the second airflow atomizing nozzle 6053 is distributed at equal intervals on the outside of the longitudinal airflow pipe 6052 and is arranged at an angle to guide the side-blown airflow at an angle.

[0040] In summary, during the drying process of the rice protein peptides by rotating the conveying support sleeve 6 and using the stirring blades 604 to agitate the tube, the bidirectional jetting airflow from the first airflow atomizing nozzle 6051 and the second airflow atomizing nozzle 6053 can be used to enhance the drying effect. The transverse airflow pipe 605 and the longitudinal airflow pipe 6052 are both connected to the conveying support sleeve 6, and a rotating seal is provided at the connection between the upper end of the conveying support sleeve 6 and the sealing cover plate 3. The sleeve is also connected to the temperature controller 8 via the first connecting pipe 7. When the compressor 10 draws in airflow, it is transported to the temperature controller via the second connecting pipe 9. The fluid is then heated by the temperature controller 8 and then transported from the first connecting pipe 7 to the transport support sleeve 6. It is then transported through the cavity in the middle of the transport support sleeve 6 to the transverse airflow pipe 605 and the longitudinal airflow pipe 6052. Finally, it is sprayed outwards from the first airflow atomizing nozzle 6051 and the second airflow atomizing nozzle 6053. (The first airflow atomizing nozzle 6051 and the second airflow atomizing nozzle 6053 are both German Gea dual-fluid nozzles; the temperature controller 8 is a German Leister-SND-50; and the compressor 10 is a Siemens 9-26-12.5D).

[0041] Furthermore, the second airflow atomizing nozzle 6053 is evenly distributed vertically on the outer side of the longitudinal airflow pipe 6052, and the second airflow atomizing nozzle 6053 is inclined, with its inclination angle forming an angle of 30°-70° with the inner wall of the drying tower body 1. When the conveying support sleeve 6 is rotated clockwise, it can drive the transverse airflow pipe 605 to rotate in a circular motion. At this time, the lateral jet airflow of the second airflow atomizing nozzle 6053 can avoid direct impact on the inner wall of the drying tower body 1. The inclined state can not only prevent rice protein peptides from splashing inside the drying tower body 1, but also scrape off the rice protein peptides adhering to the inner wall of the drying tower body 1. This can maintain the functional activity of the rice protein peptides and can also cooperate with the stirring blades 604 for drying treatment. Finally, it can be discharged from the valve-type discharge pipe 2.

[0042] Example 3

[0043] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0044] The above-mentioned bidirectional airflow injection of the first airflow atomizing nozzle 6051 and the second airflow atomizing nozzle 6053, along with the agitation and drying treatment of rice protein peptides by the stirring blades 604, not only improves the drying effect but also prevents rice protein peptides from adhering to the inner wall of the drying tower body 1, thus avoiding excessive accumulation of rice protein peptides on the inner wall of the drying tower body 1, thereby preventing product contamination and ensuring the quality of the produced products.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
