Efficient wheat flour screening device for food processing

Abstract

The invention discloses an efficient wheat flour screening device for food processing. The screening device comprises an excitation vibration sieve assembly (1) formed by sequentially and axially screwing and butting a first-stage excitation vibration sieve, a second-stage excitation vibration sieve and a third-stage excitation vibration sieve into a whole, and an excitation vibration source mechanism is arranged at the bottom of the excitation vibration sieve assembly (1); and the excitation vibration source mechanism comprises an excitation vibration box (2), a motor (3) is fixedly arrangedat the end part of the excitation vibration box (2), a driving shaft rod (4) is arranged at the output shaft end of the motor (3), and the driving shaft rod (4) is horizontally arranged in the excitation vibration box (2). The screening device is simple in structure, the excitation vibration source mechanism can drive the excitation vibration sieve assembly to vibrate in the axial direction and the radial direction, vibration in the axial direction is directly applied to screening, vibration in the radial direction can rapidly spread wheat flour in a rotary vibrating sieve while further improving the screening effect, and the overall screening efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field related to food processing machinery, in particular to a high-efficiency screening device for wheat flour for food processing. Background technique [0002] Generally, the flour obtained during the milling process of wheat flour processing equipment for food processing can be roughly divided into three parts, namely large endosperm agglomerates, starch granules and matrix fragments. The sieving standard of flour in the milling process of wheat flour processing equipment: the particle size and protein content of these three parts are different, and those less than 17um are almost all small protein fragments and small starch granules, and the protein content is high, which is almost the average of the original powder 2 times the protein content; 17-40um is mainly large starch grains, the protein content is small, which is half of the average protein content of the original flour; 40-200um is mainly endosperm c...

AI Technical Summary

Problems solved by technology

In the process of application, since the excitation source is only in the horizontal direction, the wheat flour in the vibration sieve will be stacked, so the overall screening efficiency is poor, so how to quickly spread the wheat flour in the rotary vibration sieve as soon as possible And screening is the best way to improve screening efficiency
