Description

Technical Field

[0001] The invention relates to the technical field of wheat seed crushing, and in particular to a crushing device for wheat seed sample processing. Background Art

[0002] Wheat seeds usually have a brown or golden outer skin, and the inside of the seeds contains starch, protein, cellulose and various nutrients. Wheat seeds are often used to produce wheat flour and other pasta products. They can also be used as feed and raw materials for processing wheat germ oil, making it an important economic crop. Therefore, whether in scientific research institutions, seed companies or agricultural production, the processing of wheat seed samples is very important. Through crushing, data such as the particle composition and chemical composition of wheat seeds can be obtained in order to gain an in-depth understanding of the characteristics and functions of the seeds; through crushing, wheat seeds can be turned into a particle size suitable for flour processing for subsequent processing into flour and other pasta products. In general, the background of wheat seed crushing involves multiple fields such as scientific research, food processing, animal husbandry and agricultural production, with the aim of studying, producing and utilizing wheat seeds and their derivatives.

[0003] However, the existing crushing equipment for processing wheat seed samples still has the following deficiencies in the actual working process: when crushing wet wheat seed samples, since wet wheat seeds have a certain adsorption capacity, the wheat seeds will adsorb to the inner wall of the equipment and the sieve frame, which is difficult to handle. The current crushing equipment does not have a mechanism to deal with wheat seeds adhered to the sieve frame or the inner wall of the equipment. If it is not handled for a long time, it will cause blockage to the equipment and affect the normal crushing function of the equipment; in addition, when faced with different crushing needs, the current crushing equipment does not have the function of easily adjusting the gap between the working rollers. The different gap sizes between the working rollers can be used to make corresponding treatments when faced with different crushing needs, reducing the limitations of the equipment.
