Description

Technical Field

[0001] This utility model relates to the field of gyratory screen technology, specifically a gyratory screen for starch sieving. Background Technology

[0002] The circular gyratory screen achieves uniform dispersion and efficient classification of materials by simulating the three-dimensional motion trajectory (planar circular motion + upward parabolic motion) of manual sieving. In the chemical and pharmaceutical industries, the gyratory screen can sieve fine powders such as sugar powder, starch, and aluminum powder, avoiding agglomeration and contamination.

[0003] Existing gyratory screens for starch screening, such as the gyratory screen for starch processing disclosed in CN221472569U, have the advantage of reducing the lateral force on the gyratory screen during starch screening and reducing vibration caused by the lateral force. However, the screen plates inside this gyratory screen are not convenient to remove for thorough cleaning. Therefore, we propose a gyratory screen for starch screening. Utility Model Content
