Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, in particular to a raw material crushing and grinding device for flour processing. 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. Flour (wheat flour) is the staple food in most parts of northern China. There are many kinds of food made from flour, with various styles and different flavors. Whole wheat flour is made from whole wheat that is only crushed without removing the bran. It is a flour made from the whole wheat including the bran and germ. The bran in wheat contains cellulose with extremely high nutritional value.

[0003] For example, the authorization announcement number CN213493995U is a fine grinding and screening device for flour production. The above document is provided with a screening frame, a first motor, a first tooth piece, a grinding shaft, a second tooth piece and a screen. The operation of the first motor can drive the first tooth piece and the grinding shaft to rotate, thereby driving the second tooth piece to rotate relatively, so that the two grinding shafts rotate relatively. After the wheat is poured into the box, the wheat can be fully crushed and ground. The crushed wheat will fall into the screening frame, and the screen can filter out large particles of crushed materials. The screening frame can be taken out of the box, so that the user can filter out large particles. The crushed materials of the grains are crushed and ground again to prevent the flour from containing too many impurities. However, the crushing and grinding device in the above-mentioned document crushes the wheat through the crushing component before grinding the wheat, and then screens the wheat with smaller particles through the screen, while the wheat with larger particles needs to stay on the screen. After using it for a period of time, the screen is piled up with a lot of accumulation and needs to be cleaned. In the process of cleaning the screen in the above-mentioned document, the crushing and grinding device needs to be stopped, the screen needs to be pulled out for cleaning, and then the screen needs to be reset before the wheat can be ground again, which leads to low flour grinding efficiency and affects work efficiency.
