Grinding and screening device for flour production and processing

Abstract

The grinding and screening device for flour production and processing comprises a material collecting box, a grinding box and a screening box, the grinding box is fixedly installed at the top of the material collecting box through a support, a grinding cylinder is rotatably installed in the grinding box in the vertical axial direction, and a grinding cavity is formed between the inner wall of the grinding box and the grinding cylinder; the bottom of the grinding box is fixedly provided with a discharging pipe communicated with the grinding cavity, the discharging pipe penetrates out of the box bottom of the grinding box, the screening box is rotationally installed at the bottom of the grinding box through a universal joint and located over the material collecting box, the universal joint comprises a ball cover and a ball head, the ball cover is installed on the grinding box, and the ball head is connected with the ball cover. The ball head is installed on a screening box, a net-shaped annular plate is arranged on the screening box, an annular groove is formed in the portion, located at the bottom of the net-shaped annular plate, of the screening box, a transmission rod is arranged on the material collecting box in a rotating mode, the shaft portion of the transmission rod is coaxial with the universal joint, and a scraping plate is hinged to the top end of the transmission rod.

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...
