[0013] Beneficial Effects: This application provides a spray drying device for drying food additives. During the drying operation, a fan draws air from inside the filter box and delivers it to the heating box. When the fan draws air from inside the filter box, the air first enters the filter box from one side. Inside the filter box, it undergoes a first filtration through the filter element in the second filter element area, and then a second filtration through the filter element in the first filter element area. After the filter element has been used for a certain period of time, one filter element inside the pusher box is pushed to the bottom of the pusher end of the lower pusher. The pusher end of the lower pusher pushes this filter element downwards into the pusher box. At this time, the pusher box pushes the filter element into the first filter element area inside the filter box, and pushes out the filter element that was originally in the first filter element area from the filter box, thus replacing the secondary filter element. The filter cartridge used in the secondary filtration is then adsorbed by the adsorption end of the adsorption element. Driven by the moving frame, the used filter cartridge is moved to the second filter cartridge area and pushed inside by the adsorption element. This pushes the primary filter cartridge, which was originally inside the second filter cartridge area, out of the filter box. The primary filter cartridge falls off under gravity. Throughout the process, the secondary filter cartridge can be replaced without stopping the machine, and the used secondary filter cartridge can be moved to the primary filtration position, i.e., the second filter cartridge area. This process continues, extending the filter cartridge's service life. The mechanized and automated replacement saves time and improves the efficiency of additive drying. Attached Figure Description

[0025] The working principle of this spray drying device for drying food additives is as follows: During the drying operation, the fan 120 draws air from inside the filter box 210 and delivers it to the heating box 110. When the fan 120 draws air from inside the filter box 210, the air first enters the filter box 210 from one side. Inside the filter box 210, it first undergoes filtration through the filter element 270 inside the second filter element area 212, and then passes through the first filter element area 211. The filter element 270 in the filter box performs secondary filtration. After the filter element 270 has been used for a certain period of time, one of the filter elements 270 inside the push box 240 is pushed to the bottom of the push end of the push member 230. The push end of the push member 230 pushes this filter element 270 downward into the push box 240. At this time, the push box 240 pushes the filter element 270 into the first filter element area 211 inside the filter box 210, and pushes the filter element 270 that was originally in the first filter element area 211 out of the filter box 210. In other words, when replacing the secondary filter element 270, the used secondary filter element 270 is adsorbed by the adsorption end of the adsorption element 250. Driven by the moving frame 260, the used secondary filter element 270 is moved to the side of the second filter element area 212. The adsorption element 250 pushes the used secondary filter element 270 into the second filter element area 212. At this time, the primary filter element 270, which was originally in the second filter element area 212, is pushed out of the filter box 210. The primary filter element 270 will fall off under the action of gravity. During the entire process, the secondary filter element 270 can be replaced without stopping the machine, and the used secondary filter element 270 is moved to the primary filtration position, that is, into the second filter element area 212. This process continues to improve the filtration life of the filter element 270. At the same time, the mechanized and automated replacement of the filter element 270 saves time and improves the efficiency of additive drying.

[0026] It should be noted that the first telescopic component 214, the second telescopic component 222, the third telescopic component 231, the fourth telescopic component 242, and the fifth telescopic component 251 are all electric push rods.
