Design and application of automatic precision feeding equipment for threshing and redrying process

  Background  This study aims to solve the problems of artificial influence factors and low mixing uniformity in the feeding process of threshing and redrying.  Methods  An automatic precision feeding equipment composed of a feeding control device and an automatic feeding device was designed for threshing and redrying. Tobacco leaves after loosening and resurgence were load into the customized smoke basket and transported to the feeding device. Then the feeding control device performed the feeding design, the grabbing claw of the automatic feeding device grabbed tobacco leaves from the smoke basket into the feed roller for quantitative feeding. After that, the leaves fell to the conveyor belt for the next process to complete the automatic feeding and uniform mixing of multi-level and multi-proportion tobacco leaves.  Results  ① For the designed feeding task of 6000 kg/h, the feeding flow of the automatic precision feeding equipment fluctuated within the set error range of 2%; when working continuously, the feeding stability per unit time was higher and more uniform than manual work; ②The mixing uniformity errors of automatic feeding and manual feeding were 0.2% and 3.5%, respectively. The layered-type feeding method based on automatic feeding equipment can realize the uniform premixing of tobacco leaves.③The nicotine CV value of redried tobacco strips under automatic feeding was lower than that under manual feeding by 0.68%.  Conclusion  This proposed equipment can save costs, and improve the automation and homogenization processing level for threshing and redrying process.
