It has the effects of promoting cartilage regeneration, anti-inflammatory, lowering blood lipids, and anti-coagulant activity. It can effectively prevent arthritis. In recent years, it has also been found to have anti-cancer and anti-HIV effects.

[0003] The Chinese patent with the existing authorization announcement number CN116678185B discloses a method and equipment for producing sodium chondroitin sulfate, and relates to the technical field of sodium chondroitin sulfate production.

The present invention connects the drum to the cam through a rotating component, and the drum is driven to rotate eccentrically during the rotation of the cam, so as to avoid the possibility that the material is uniformly attached to one side of the inner wall of the drum due to centrifugal force when the drum rotates concentrically.

[0004] The disadvantages of the above-mentioned prior art solutions are: coarse particles are dehydrated, alcohol is not easy to penetrate, dehydration is incomplete, drying time is long, alcohol is not easy to recover, chondroitin sulfate is dark in color, alcohol residue is also high, and it still needs to be crushed later, resulting in increased loss.

[0049] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0050] The sodium chondroitin sulfate precipitated by adding alcohol is added with anhydrous alcohol for dehydration, and then crushed with a wet grinder to a fineness of more than 80 meshes, and then dehydrated with anhydrous alcohol to a moisture content of less than 8%. The dehydrated sodium chondroitin sulfate is placed in a centrifuge to separate free alcohol, and then the sodium chondroitin sulfate powder separated from the free alcohol is passed through the feed channel 146 and the connecting channel 145 and then through the feed port 142 into the drying mechanism 13 and the drying mechanism 2 14, and the mechanism rotating plate 131 is driven to rotate by the driving motor 2 15, and the rotation of the mechanism rotating plate 131 can make the arc-shaped drying teeth 134 arranged relatively staggered As well as the arc-shaped friction of the arc-shaped drying teeth 143, the rotation of the mechanism rotating plate 131 can throw the material to be dried located in the middle of the mechanism rotating plate 131 toward the two sides of the mechanism rotating plate 131 through centrifugal force, and the material to be dried is gradually friction-dried by the mutual friction between the arc-shaped drying teeth 134 and the arc-shaped drying teeth 143.

[0051] Before dehydration, the coarse particles of sodium chondroitin sulfate are preliminarily crushed, and then dehydrated with anhydrous alcohol. By crushing the sodium chondroitin sulfate and then dehydrating it with alcohol, the dehydration of the particles is more uniform and thorough, and the temperature during the drying operation can be reduced.

The dust-raising arc slope 132 and the centrifugal blades 11 can be set to automatically collect the dried powder, thereby improving the automation degree of the device and being beneficial to the continuous production, and improving the efficiency of the sodium chondroitin sulfate drying process. At the same time, the airtight design of the device can be improved, which is beneficial to the recovery of alcohol and the reduction of chemical gas emissions, making it more environmentally friendly.
