[0002] Flavored salt is often processed by dry or wet processes. The dry mixing process is relatively simple, but most of the materials on the market have a relatively fine particle size, and stratification will occur during dry mixing, which has an adverse effect on the product quality. Therefore, a wet mixing process needs to be adopted. There will inevitably be a drying step after wet mixing. However, if the salt is not constantly scattered during the drying process in the drying box, it is extremely easy to agglomerate into a block, resulting in a decrease in the yield.

[0003] When the existing drying tray dries salt, the salt is mostly piled up on the drying tray, agglomerates into a block, has a limited heat absorption area, is not conducive to the drying and volatilization of moisture, has low efficiency, and is rather troublesome to take the material.

[0042] The driving mechanism 5 includes a connecting rod 504, a driving wheel 502, a driven wheel 503, and a driving motor 501. The eccentric wheels 405 are connected by the connecting rod 504. The driven wheel 503 is installed at the central position of the connecting rod 504. The driven wheel 503 meshes with the driving wheel 502. One side of the driving wheel 502 is fixedly connected to the output end of the driving motor 501. The driving motor 501 is installed on the inner wall of the cavity 414. The other side of the driving wheel 502 is rotatably connected to the inner wall of the cavity 414 on the side away from the driving motor 501 through a fixing rod 505.

[0043] During use, the driving motor 501 in the cavity 414 of the activity block 406 drives the driving wheel 502 to rotate, thereby driving the driven wheel 503 to rotate accordingly. The two eccentric wheels 405 connected by the connecting rod 504 rotate. When the eccentric wheels 405 rotate, the first spring 403 and the second spring 404 are compressed and restored, so that the activity block 406 vibrates up and down.

Example 3

[0044] Please refer toFigures 6-7 , the breaking mechanism 6 includes a telescopic rod 601, a rotating rod 602, and a rolling roller 603.

The transmission pulley 609 is connected to a transmission motor 608. The transmission motor 608 is installed at the bottom of the receiving plate 409. An activity slot 607 is provided at the top of the activity cavity. The bottom of the telescopic rod 601 extends into the activity slot 607 and is movably connected to the ball screw 605 through a ball nut 606. The rotating rod 602 is installed between the telescopic ends of the symmetric telescopic rods 601. The rolling roller 603 is rotatably installed on the rotating rod 602. Limit baffles 604 are provided at both ends of the rolling roller 603. The limit baffles 604 are fixedly connected to the rotating rod 602.

[0045] During use, first, the telescopic rod 601 drives the rolling roller 603 on the rotating rod 602 to move towards the baking tray 8 until it contacts the baking tray 8, and then the telescopic rod 601 stops telescoping. Then, the transmission motor 608 rotates forward and backward to drive the ball screws 605 at both ends of the receiving plate 409, so that the ball nuts 606 on the ball screws 605 drive the movable rod to reciprocate on it, thereby realizing that the rolling roller 603 rolls back and forth in the salt pile on the baking tray 8. The salt particles that are not completely shaken and dispersed on the baking tray 8 can be further dispersed, preventing the salt particles from accumulating into blocks, thereby improving the dispersion efficiency. In this embodiment, the starting end of the rolling roller 603 extends beyond the edge of the baking tray 8, and it will not affect its movement when the baking tray 8 is being emptied. Before the rolling roller 603 moves towards the baking tray 8, first, the transmission motor 608 drives the ball screw so that the rolling roller 603 first moves above the baking tray 8, and then the rolling roller 603 starts to move downward. A number of spikes for dispersing salt blocks are provided on the rolling roller 603, which is beneficial to the dispersion of salt blocks. Embodiment 4

A limiting plate 801 is fixedly installed on one side of the baking tray 8 close to the locking block 411, and a limiting groove 802 matching the locking block 411 is provided on the limiting plate 801.

[0048] During use, when it is necessary to pour out the salt particles after drying is completed, the cylinder 701 on the drying oven 1 can be telescoped into the receiving plate 409 to fit against the bottom of the baking tray 8, and then the baking tray 8 is pushed to rotate around the hinge to pour out the salt particles on the baking tray 8. Before the cylinder 701 pushes the baking tray 8, the electric motor 413 is first driven to drive the locking rod 410 to rotate, so that the locking block 411 on the locking rod 410 releases the restriction on the limiting plate 801 of the baking tray 8, and then the baking tray 8 is pushed. Through the above design, it is beneficial to pour out the salt particles and improve work efficiency.
