Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flour production, and more specifically to a flour sorting sieve. Background Art
[0002] Flour sorting sieve usually refers to flour grading screening, which is used to separate flour into particles of different particle sizes. This screening equipment usually uses a vibrating screen to separate flour particles of different particle sizes through the apertures on the screen. In industrial production, flour sorting sieves can help manufacturers control the quality and particle size of flour to meet the requirements of different products. By adjusting the parameters of the screening equipment, accurate screening of flour can be achieved to obtain the ideal particle size range.
[0003] However, in the process of sieving flour, a large amount of flour is usually directly placed on the surface of the sieve, causing the sieve to be blocked, resulting in poor sieving effect and failure to effectively separate the flour particles according to the required particle size. This will slow down the sieving step in the production process, thereby reducing production efficiency and may result in uneven distribution of flour particles and unstable quality.
