Description

Technical Field

[0001] The utility model relates to the technical field of powder screening machine equipment, and more specifically, to a screw type powder screening machine. Background Art

[0002] In food processing, many materials are needed, and flour is one of them. However, flour is processed into coarse and fine flours, so the flour needs to be screened to separate the coarse flour from the fine flour. Usually people use a sieve to screen the flour. Since the sieve needs to be shaken continuously, it is laborious over time, and a large amount of flour accumulates on the sieve and is screened, making it difficult for the sieve to screen the flour. Therefore, another person is needed to help pour the flour into the sieve part by part for screening, and stop to rest after screening for a while. This work is inefficient and troublesome. In addition, during the sieving process, the separated materials fly everywhere, resulting in a lot of dust in the working area and polluting the working environment. For this reason, we propose a screw sifter. Utility Model Content
