Description

Technical Field

[0001] The utility model relates to the technical field of flour production, in particular to a flour impurity detection device. Background Art

[0002] All flour and grain products contain complex carbohydrates (starch), vitamins, minerals and proteins. They are also the main source of energy for us every day, such as steamed bread, desserts and pasta made of flour, etc. However, the content of lysine (basic amino acid) in wheat protein is low. When wheat is ground into flour, impurities such as bran or small stones in wheat are mixed in the flour. In order to improve the processing quality of flour, it is necessary to filter the flour and detect impurities in flour during flour production.

[0003] After filtering the flour, it is necessary to detect the impurities in the flour again. During the detection, the flour is generally spread on a white tray, and the impurities contained in the flour are detected by naked eyes. The larger impurities in the flour are removed by filtering, and the remaining impurity particles are smaller and are not easily detected in the flour, thereby affecting the detection quality of the flour impurities. In order to solve the above problems, a flour impurity detection device is proposed in the present application. Utility Model Content
