Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, in particular to a high square plansieve for flour processing. Background Art

[0002] Flour milling is a complex process involving multiple steps and technologies, aimed at converting wheat into high-quality flour products. During flour production, the ground flour needs to be sieved and graded to remove impurities. This is usually done using a high-square-meter plansieve for flour milling.

[0003] The existing plansieve for flour processing is driven by a motor to shake the plansieve, so that the flour is filtered and sieved in the sieve grid to complete the plansieve grading of the flour.

[0004] The sieve grids inside the existing high plansieve for flour processing need to be pressed and limited to prevent gaps from appearing between different sieve grids, which would lead to a deterioration in the screening effect. However, this makes the sieve grid removal process more cumbersome. The sieve grids need to be unlocked first before they can be removed, and they need to be removed from top to bottom. Therefore, we propose a high plansieve for flour processing. Utility Model Content
