[0030] Specific as Figure 1 , Figure 3 and Figure 4 As shown, when using this structure, the hyaluronic acid stock solution is poured into the top of the device body 1 through the feeding funnel 2, filtered through the filter plate 11, and the large solid particles therein are filtered out.

The drive motor 16 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the fan 18 and the scraper 19 to rotate. The fan 18 rotates to quickly dry the atomized liquid, and at the same time, the heating tube 15 installed in the heating chamber 14 is powered on and heated to dry the atomized liquid. This structure can quickly dry the liquefied hyaluronic acid to form micromolecular hyaluronic acid powder. At the same time, the scraper 19 is used to rotate and scratch the inner wall of the device body 1 to prevent powder from adhering to the inner wall of the device body 1, which also provides convenience for subsequent cleaning of the device.

[0036] Working principle: the hyaluronic acid solution is poured into the device body 1 through the feeding funnel 2, filtered through the filter plate 11, and large solid particles are separated. The pneumatic telescopic rod 13 is started, and the pneumatic telescopic rod 13 is used to form a thrust on the push plate 6, and the push plate 6 is driven by the pneumatic telescopic rod 13 to move from left to right so that its bottom scrapes the partition 7, and the separated large particles of solid are pushed to the right side, and the top block 25 is used to touch the two sides of the partition 7, and then the partition 7 is limited by the limit block 8 and the limit groove 21, so that the partition 7 moves laterally along the limit groove 21, so that the latch 23 leaves the latch groove 22 to create a gap between the bottom end of the partition 7 and the limit block 8, so that the large particles are fixed and fall along the discharge slope 24 to the waste box 3 for unified collection. After the collection is completed, the push plate 6 is reset, and the partition 7 returns to its original position under the elastic force generated by the deformation of the telescopic sleeve 9 and the spring 10, and returns to the inside of the latch groove 22 through the latch pin 23 to make the partition 7 and The filter plate 11 is fitted to form a closed state to prevent the next time the liquid is fed from overflowing from the gap between the partition plate 7 and the filter plate 11. The filtered liquid falls into the interior of the atomizer 12. When the atomizer 12 is inflated and pressurized through the air inlet pipe 20, the internal liquid is atomized and falls on the bottom of the device body 1. At the same time, the heating tube 15 and the drive motor 16 are started, and the heating tube 15 is used to heat and dry the interior. The fan 18 and the scraper rod 19 are then driven by the drive motor 16 to rotate, so that the fan 18 rotates while the atomized liquid is air-dried to speed up the drying efficiency. At the same time, the scraper rod 19 is used to scratch the inner wall of the device body 1 to prevent the dried hyaluronic acid powder from adhering to its inner wall. After the interior is dried, the solenoid valve 5 is opened to collect the micromolecular hyaluronic acid powder. This structure not only does not require frequent replacement of the filter plate 11, but also facilitates the recycling of large solid particles, while speeding up the drying efficiency and facilitating the cleaning of the residue on the inner wall of the device body 1 after drying.
