Method for removing hemp thread and hemp velvet from threshing and redrying

Abstract

The invention relates to a method for removing hemp thread and hemp velvet from threshing and redrying, which belongs to the technical field of threshing and redrying and impurity removal. The methodcomprises seven steps of weighing, mixing, pressing, air drying, cutting, processing and hanging. By the adoption of the method for removing the hemp thread and hemp velvet from threshing and redrying, a characteristic of mutual adhesion of the hemp thread and the hemp velvet is utilized, the hemp thread and the hemp velvet are mixed and pressed, a prepared hemp thread and hemp velvet impurity-removing board is firm and durable; the hemp thread and the hemp velvet are manufactured into a hemp thread and hemp velvet impurity-removing board according to a mass ratio of 1 to 3, so that the hemp velvet provided by a surface of the prepared impurity-removing board has good adsorption and bonding effects; in a process of conveying tobacco leaves, the hemp thread and hemp velvet impurity-removingboard is in contact with the tobacco leaves and rubs with the tobacco leaves to generate static electricity, so that impurities such as the hemp thread, the hemp velvet and the like mixed in the tobacco leaves are absorbed; the structure is simple, a removal rate of the hemp thread and the hemp velvet is high, and cleaning is convenient.

Description

technical field [0001] The invention belongs to the technical field of threshing and re-roasting, and specifically relates to a method for removing threshing and re-roasting hemp silk and velvet. Background technique [0002] At present, during the production and processing of redrying in China, tobacco leaves are generally packed in sacks. Tobacco leaves will be mixed with some non-smoke debris during the process of purchasing and packaging, such as cloth, plastic, hemp, paper, etc. The quality and purity of tobacco leaf raw materials are directly related to the quality of cigarette products. At present, manual selection and Elimination (such as selection table), installation of foreign matter removal machine and hemp removal device to remove impurities in tobacco leaves to improve the purity of tobacco leaves. However, the cost of manual removal is high and the removal rate of debris is low. [0003] Because hemp silk and hemp velvet are small, large in number, not easy ...
