Screening and impurity removing process in rice flour processing

Abstract

The invention discloses a screening and impurity removing process in rice flour processing. The screening and impurity removing process comprises the following steps of 1, primary filtration, specifically, putting rice flour to be screened and subjected to impurity removal into a primary filtration mechanism for screening; 2, dispersing, specifically, dispersing the primarily filtered rice flour,dispersing the rice flour in a dispersing mechanism, and enabling the dispersed rice flour to fall into a frame box; and 3, refined filtration, specifically, when the rice flour enters the frame box from the dispersing mechanism, removing impurities through filtration of a second filter screen plate. In the extraction and adsorption processes, particles larger than meshes of a magnetic screen plate are filtered out and fall into a loading box, and the particles cannot enter an extraction pipe. Particles made of other materials are large in weight and are difficult to be sucked into a suction pipe by wind power so that the particles made of the other materials can remain in the loading box and cannot enter a middle frame. Preliminary filtration is conducted, and iron particles doped in therice flour, the particles made of the other materials and the particles larger than the meshes of the magnetic screen plate are screened out.

Description

technical field [0001] The invention relates to a process for removing impurities, in particular to a process for screening and removing impurities in rice flour processing, and belongs to the field of rice flour processing applications. Background technique [0002] Rice flour is a powdery material made by grinding rice as a raw material. In order to ensure the quality of rice noodles, the process of screening and removing impurities is commonly used to remove impurities from rice noodles. [0003] But the screening impurity removal process in the existing rice flour processing still has certain deficiencies. The existing screening and impurity removal process in rice flour processing is not thorough enough to remove impurities in rice flour, and the efficiency of impurity removal is low. At the same time, the equipment used for impurity removal is not convenient and fast enough, and cannot be adjusted according to actual needs, and has relatively large limitations. Con...
