In the embodiment, by setting the inner diameter of the first cylinder 11 to be smaller than the inner diameter of the second cylinder 12, collagen is crushed by the extrusion force of the first channel in the reciprocating motion process between the second cylinder 12 and the first channel with the smaller inner diameter, so that the particle size of the collagen is reduced, the molecular weight of the collagen is reduced, the mixing efficiency is improved, the collagen and the liquid additive are fully mixed, and a more uniform mixed solution is obtained, thereby avoiding the collagen in the mixed product from being aggregated again, ensuring the stability of the mixed product, and improving the quality of the mixed product; in addition, adjacent mixing chamber 1 links to each other through first barrel 11 and forms first passageway, and this first passageway not only can play the connection effect, can provide bigger atress space for collagen simultaneously, further improves the mixing efficiency between collagen and the liquid mixture.

Specifically, the amount of collagen treatment is adjusted according to the inner diameters of the first cylinder 11 and the second cylinder 12. Since collagen has a high viscosity and may partially adhere to the inner walls of the first and second cylinders 11 and 12, a proper amount of collagen may be treated according to the inner diameters of the first and second cylinders 11 and 12 in order to ensure the yield of collagen and reduce the molecular weight of collagen, thereby making the mixed solution formed between collagen and the liquid additive more uniform.

Specifically, in order to improve throughput and production efficiency, this mixing arrangement includes multiunit mixing chamber 1, and every group mixing chamber 1 includes two symmetric distribution's mixing chamber 1, and the first barrel 11 in one of them mixing chamber 1 in every group mixing chamber 1 communicates with the first barrel 11 in another mixing chamber 1 to form first passageway.

As an embodiment, the mixing device further includes a liquid passing plate 14, the liquid passing plate 14 is provided with a through hole 15, the first cylinder 11 in one mixing cavity 1 is communicated with the first cylinder 11 in the other mixing cavity 1 through the through hole 15, and a first passage is formed between the inside of the first cylinder 11 in the one mixing cavity 1, the inside of the first cylinder 11 in the other mixing cavity 1 and the inside of the through hole 15. The liquid passing plate 14 is arranged to connect one of the mixing cavities 1 with the first cylinder 11 of the other mixing cavity 1, so that the phenomenon of liquid leakage caused by the breakage of the joint of the two opposite first cylinders 11 after pressure is applied can be prevented; in addition, the through holes 15 of the liquid passing plate 14 can also extend the length of the first channel, so as to provide a larger stress space for collagen, and further improve the mixing efficiency between the collagen and the liquid mixture.
