[0002] Lactic acid powder is a multifunctional additive widely used in food, medicine, chemical industry and other fields. It is made of lactic acid through dehydration or spray drying and appears as a white powder. When the lactic acid powder is stretched out, it needs to be sieved through a rotary sieve to remove impurities in the lactic acid powder and improve the quality of the lactic acid powder.

[0003] The existing rotary screen is basically composed of a frame and a screening net. A vibrator is arranged inside the frame. After the staff pours the lactic acid powder to be screened into the frame, the blocker drives the frame to vibrate, so that the screening net screens the lactic acid powder. However, the lactic acid powder poured into the frame by the staff cannot be evenly scattered on other parts of the screening net. The poured lactic acid powder piles up together, which can easily cause the screening net to be blocked, thereby reducing the screening efficiency of the rotary screen to a certain extent.

[0004] Therefore, it is necessary to provide a new rotary vibrating sieve for screening lactic acid powder to solve the above-mentioned technical problems. Utility Model Content
