A grinding and screening device for flour production and processing

Abstract

The object of the present invention is to provide a grinding and screening device for flour production and processing, comprising a collection box, a grinding box and a screening box, the grinding box is fixedly installed on the top of the collection box through a bracket, and the grinding box is vertically A grinding drum is installed in a straight and axial direction, and a grinding cavity is formed between the inner wall of the grinding box and the grinding drum. The bottom of the grinding box is fixedly installed with a feeding tube that communicates with the grinding cavity. The box bottom of the box is pierced, and the screening box is rotated and installed on the bottom of the grinding box through a universal joint, and is located right above the collecting box. The universal joint includes a ball cover and a ball head, and the ball cover is installed on the On the grinding box, the ball head is installed on the sieving box, and the sieving box has a mesh ring plate, and the sieving box has an annular groove at the bottom of the mesh ring plate. A transmission rod is rotated, the shaft portion of the transmission rod is coaxial with the universal joint, and the top end of the transmission rod is hinged with a scraper.

Description

technical field [0001] The invention relates to a screening device, in particular to a grinding and screening device for flour production and processing. Background technique [0002] Flour is a powder made from wheat. According to the protein content of 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, and there are many kinds of food made from flour. , The flavor is different. Whole wheat flour is the whole wheat flour that is only ground without the bran removal process. It is the whole wheat flour that contains all the bran and germ. The bran in the wheat Contains high nutritional value of fiber. [0003] In the prior art, the flour screening device mainly relies on the vibrating screen, that is, the screen plate is connected with the vibration motor to realize the vibration of the screen plate, so as to realize the material screening. In...
