[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] The utility model provides a high-efficiency spray drying device for processing modulated milk powder. The airflow enters the drying mechanism through the air intake mechanism. When the airflow enters, it is pre-filtered by the filter component, which reduces the workload of the sterile filter and extends the service life of the sterile filter. Figure 1-Figure 5 , including: a drying mechanism 100, an air intake mechanism 200 and a filtering component 300.

[0031] The drying mechanism 100 includes a spray dryer 110, a feed pipe 120, an atomizing nozzle 130, a discharge pipe 140, an air inlet pipe 150, and a sterile filter 160. The feed pipe 120 is provided at the top of the spray dryer 110, the atomizing nozzle 130 is provided on the feed pipe 120, the discharge pipe 140 is provided at the bottom of the spray dryer 110, the air inlet pipe 150 is provided on the side wall of the spray dryer 110, the air inlet pipe 150 is provided on the sterile filter 160, and the right end of the air inlet cylinder 210 is connected to the air inlet pipe 150 via a flange;

[0032] The airflow enters the spray dryer 110 through the air inlet pipe 150 and is filtered by the sterile filter 160 .

[0033] The air intake mechanism 200 is arranged at the air intake end of the drying mechanism 100. The air intake mechanism 200 includes an air intake cylinder 210 and a retaining ring 220. The retaining ring 220 is arranged on the inner wall of the air intake cylinder 210.

[0034] The left end of the air intake cylinder 210 is open, and the right end is connected to the air intake pipe 150 , so that air flows in through the left end of the air intake cylinder 210 .

[0035] The filter component 300 is disposed on the retaining ring 220 , and the filter component 300 is used to pre-filter the airflow.

[0036] Specifically, the filter component 300 includes a filter screen 310, a magnetic belt 320 and an axial hole 330. The outer ring of the filter screen 310 is provided with a magnetic belt 320 adsorbed by the retaining ring 220. The axial hole 330 is provided in the center of the filter screen 310. The filter screen 310 is magnetically connected to the retaining ring 220 through the magnetic belt 320.

[0037] Since dust easily accumulates on the outside of the filter 310 and affects airflow, a cleaning mechanism 400 is provided on the shaft hole 330. The cleaning mechanism 400 includes a rotating shaft 410, an impeller 420, a connecting cover 430, and a cleaning brush 440. The rotating shaft 410 is inserted into the shaft hole 330. The impeller 420 is provided at the right end of the rotating shaft 410, and the connecting cover 430 is provided at the left end of the rotating shaft 410. The connecting cover 430 is provided with a cleaning brush 440 that contacts the filter 310.

[0038] When the air flows, the impeller 420 is driven to rotate, and the impeller 420 drives the connecting cover 430 to rotate through the rotating shaft 410 , and the connecting cover 430 drives the cleaning brush 440 to rotate to clean the filter 310 .

[0039] Since the filter 310 needs to be removed and replaced, a thread is provided on the left end of the rotating shaft 410 , and the connecting cover 430 is screwed on the left end of the rotating shaft 410 , so that the rotating shaft 410 can be removed from the filter 310 .

[0040] In order to reduce the friction between the connecting cover 430 and the filter 310, evenly distributed balls 450 are provided on the right side of the connecting cover 430. The balls 450 are used to reduce the contact friction resistance and facilitate the rotation of the connecting cover 430.

[0041] In order to facilitate observation of the filtering status, the air inlet cylinder 210 adopts a transparent cylinder, through which the internal filtering status can be observed.

[0042] During specific use, the air flow enters through the left end of the air inlet cylinder 210, and the filter screen 310 pre-filters the air flow. When the air flow flows, it drives the impeller 420 to rotate. The impeller 420 drives the connecting cover 430 to rotate through the rotating shaft 410. The connecting cover 430 drives the cleaning brush 440 to rotate to clean the filter screen 310. Then the sterile filter 160 fine-filters the air flow and blows the air flow into the spray dryer 110 for drying.

[0043] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
