Preprocessing pretreatment device for raw materials of flour

Abstract

The invention discloses a preprocessing pretreatment device for raw materials of flour, and relates to the field of processing of raw materials of flour. The device comprises a feeding hopper which isconnected to a material port of a homogenizing box, wherein a material guide housing at the lower side of the homogenizing box is in penetration connection with the rear side of a screening box; a swinging mechanism is obliquely connected to the lower part of the screening box, and a wheel disc of the swinging mechanism is connected to a motor through a belt; the motor and the swinging mechanismare mounted on a rack; and a damping cushion is arranged at the bottom part of the rack. The device is compact in structure, reasonable in design, and novel and unique in ideal; after materials are fed into the hopper, the homogenizing box is capable of controlling the material flowing speed and the flow rate, dividing the materials and roughly grading the materials, then the materials are guidedthrough the material guide housing to enter each screening plate layer of the screening so as to be screened, and finally the materials are separated through a grading plate, impurities are dischargedthrough an impurity discharging port based on specific gravity, and materials at different grades are sequentially discharged through a plurality of discharging ports.

Description

technical field [0001] The invention relates to the technical field of flour processing machinery, in particular to a pre-processing device for flour raw material preprocessing. Background technique [0002] Flour is a powder made from wheat. According to the protein content of flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. [0003] Flour (wheat flour) is the staple food in most parts of northern China, and there are many kinds of food made from flour, with various patterns and different flavors. [0004] Before the wheat is processed into flour, the wheat is mixed with a large amount of impurities, such as glume husks, branches, grass seeds, sand stones, etc. Before processing the fabric, it needs to be pre-treated to remove impurities, so that it can be processed cleanly In order to improve the grade of flour, and how to remove impurities, there are many kinds of equipment, often because of the variety and ty...

AI Technical Summary

Problems solved by technology

[0004] Before the wheat flour is processed, the wheat is doped with a large amount of impurities, such as chaff, branches, grass seeds, sand and stones, etc. Before processing the fabric, it needs to be pre-treated to remove impurities, so that it can be processed cleanly. In order to improve the grade of flour, how to remove impurities, now there are many kinds of equipment, often due to the variety of impurities in wheat, different types, and the removal of different impurities, flour processing enterprises have always been troubled
