Flour milling process of flour processing machinery

The flour milling process of flour processing machinery is composed of four major systems, namely the skin grinding system, the heart grinding system, the slag grinding system and the powder cleaning system.
The skin milling system of the complete set of flour machinery equipment is divided into the front skin mill and the rear skin mill. The task of the front skin mill is to peel the corn kernels, extract corn residue and corn heart, and the task of the rear skin mill is to scrape the endosperm. . The task of the milling system of the flour processing machinery is to grind the germ into fine powder. The powder cleaning system and the slag grinding system are the link between the skin mill and the heart grinding. They play an important role in the production of high-precision flour. The task is to purify the large, medium and small coarse particles extracted by the front skin mill system into almost The corn heart and meal without the skin layer are sent to the heart grinding system to be ground into flour. Therefore, the slag mill and the powder cleaning system are jointly responsible for the selection and purification of materials in the milling process.
The operation of flour processing machinery requires a flour cleaning process to improve flour quality. Among them, if the cleaning effect is not satisfactory, the operation can be repeated. Generally, the material under the sieve in the front and middle section of the powder cleaner is relatively pure. As the material in the middle section is gradually reduced, the material layer will be easily blown through, which will lead to the impure material under the sieve and contain fine bran stars. Flour processing machinery has sufficient number of powder cleaners, and all materials sent to the heart mill should be cleaned or a secondary cleaning process should be adopted. At this time, the not-so-pure wheat hearts are collected again, sent to the powder cleaning machine for selection, and the powder is cleaned twice, that is, repeated powder cleaning, and more pure corn hearts can be obtained than only one time.
