Blowing-type wheat glume removing roller

Abstract

The invention discloses a blowing-type wheat glume removing roller. The upper part and lower part of both ends of a shell are provided with a charging opening and a discharging opening respectively, arotary shaft driven by a driving mechanism to rotate is arranged in the shell, the rotary shaft is provided with spiral blades, one end of the shell having the charging opening is provided with an end cover, vent holes of which the diameters are smaller than wheat berries are densely distributed in the end cover, the end cover is communicated with a connecting sleeve, the connecting sleeve is provided with an air feeding pipeline communicated with the blowing opening of a blower, and the air feeding pipeline feeds airflows blown by the blower into the shell by the connecting sleeve and the vent holes in the end cover. The position of the shell located above the discharging opening is provided with a glume outlet. According to the blowing-type wheat glume removing roller, the dehulled wheat is spun, agitated, impacted and rubbed in a conveying process, and further the high speed airflows are blown inward by the connecting sleeve and the end cover, such that the residual glumes are removed under the action of an external force and are discharged by the glume outlet. The blowing-type wheat glume removing roller has the advantages of simple structure and good glume removing effect.

Description

technical field [0001] The invention relates to the field of wheat finishing, in particular to an air blast type wheat chaff removing drum. Background technique [0002] Wheat is the main food crop in my country, mainly used for making flour. After the harvested wheat ears are threshed by a thresher, they are wheat grains, which can be used for making flour. However, the threshing effect of the thresher on the wheat ears is not 100% thorough, and there are always some residual shells attached to the surface of some wheat grains. Therefore, it is necessary to pan the wheat kernels to remove these residual chaffs before milling. This method of washing with water to remove the residual shell not only wastes a large amount of water, but also part of the residual shell will still stick to the surface of the wheat grains, thereby causing a decline in the quality of the flour. Contents of the invention [0003] In order to solve the problems of waste of water resources and unc...

Problems solved by technology

[0003] In order to solve the problems of waste of water resources and unclean removal of residual husks existing in the way of washing with water before wheat flour milling in the prior art, the present invention provides a blower-type wheat chaff removal drum, which removes The dehulling drum makes the husked wheat be rotated, agitated, impacted and rubbed during the conveying process, and then blows high-speed airflow into it through the connecting sleeve and end cover, so that the remaining chaff is subjected to external force. removed and discharged through chaff outlet
