Technical Field

[0001] The invention relates to the technical field of food processing equipment, in particular to an impurity removal device in a flour processing process. Background Art

[0002] Flour is a powder made from wheat. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. There are many kinds of food made from flour, with various styles and different flavors. Flour is generally a common staple food ingredient in the north. It is a powder made from wheat. Before wheat is ground into powder, it needs to be cleaned, mainly to remove stones, wheat husks, wheat awns and other debris mixed with wheat seeds. Usually, during the processing of flour, the wheat needs to be cleaned first to prevent the impurities in the wheat from being crushed into flour, which affects the quality of the flour.

[0003] At present, most of the existing methods for removing impurities from wheat are to wash the wheat first, remove impurities such as straw and bran during the washing process, then dry the washed wheat, and then remove impurities such as soil, stones, and dust from the dried wheat through traditional wind cleaning and manual screening. This cleaning process is very troublesome and has poor cleaning effect, which greatly reduces work efficiency and is time-consuming and labor-intensive. In addition, traditional cleaning methods cause great pollution to the surrounding environment. At the same time, the supply is in short supply and is far from meeting the market demand.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] During use, the fans 21 in the first bellows 7 and the second bellows 8 are turned on by controlling the switch 26, and then the raw materials to be cleaned are put into the feeding hopper 24. As the raw materials enter the cleaning box 1 from the feeding hopper 24, the lighter impurities such as straw, chaff, and dust mixed in the raw materials are blown into the first cleaning bag 11 under the operation of the fan 21 in the first bellows 7, and then the raw materials after preliminary cleaning will fall on the first filter screen 2. Under the screening of the first filter screen 2, the heavier and larger impurities such as clods and stones mixed in the raw materials are left on the first filter screen 2. Then the raw materials after secondary cleaning penetrate the first filter screen 2 and continue to fall. Under the operation of the fan 21 in the second bellows 8, a small amount of lighter impurities such as straw, chaff, and dust that have not been cleaned in the falling raw materials are blown into the second cleaning bag 12. Then the raw materials after tertiary cleaning will fall on the second filter screen 3. After being screened by the second filter screen 3, a small amount of smaller impurities such as clods and stones are left on the second filter screen 3. Finally, After that, the raw material penetrates the second filter screen 3, falls to the bottom of the impurity removal box 1, and leaks out of the impurity removal box 1 through the discharge funnel 25. When the impurities of the raw materials to be removed are removed, the motor 4 is turned on by the control switch 26. The rotation of the output shaft of the motor 4 will drive the rotating rod 5 to rotate, and the rotation of the rotating rod 5 will drive the auxiliary plate 13 and the brush 15 to rotate. At this time, the second electric telescopic rod 14 is turned on by the control switch 26, so that the brush 15 is adjusted to a suitable position, and the surfaces of the first filter screen 2 and the second filter screen 3 are cleaned by rotation. Then, the second filter screen 3 is slightly shaken by the extension of the first electric telescopic rod 6, and the impurities on it roll down to the discharge port 16 on the second filter screen 3 through the shaking. At the same time, due to the cleaning of the brush 15, the impurities on the first filter screen 2 are also moved to the discharge port. The stopper 19 is extended upward by the extension of the third electric telescopic rod 18, thereby opening the discharge port to discharge the impurities on the first filter screen 2 and the second filter screen 3 to the outside of the impurity removal box 1.
