CN223988508U - Wheat husk removing equipment for wheat flour production - Google Patents

Abstract

This utility model discloses a wheat husk removal device for wheat flour production, relating to the field of wheat flour production and processing. The device comprises a guide frame, a primary roller, a secondary roller, a first filter screen, and a second filter screen. The primary roller initially crushes larger wheat grains, causing preliminary cracking of the husks. The secondary roller further refines the crushed wheat grains, ensuring more thorough husk removal. By gradually decreasing the roller spacing, excessive crushing of large wheat grains at the beginning, which could lead to grain breakage, is avoided, while ensuring effective removal of the husks from smaller wheat grains, improving the uniformity of husk removal. An eccentric wheel and spring vibrate the first and second filter screens simultaneously with the rotation of the primary and secondary rollers, maintaining good permeability and improving filtration efficiency. This effectively prevents processing interruptions or reduced efficiency due to filter clogging.
