AI Technical Summary

Technical Problem

During the re-drying process of blades, the uncertainty of the initial feed moisture content and the lag in detection lead to the generation of substandard feed material, affecting product quality and production efficiency.

Method used

By collecting the moisture content of the material at the air separator outlet of each stage of the blades, calculating the weighted moisture content, and combining it with the material moisture loss under temperature and humidity conditions, the moisture content of the feed material for blade re-drying is predicted, providing a scientific reference for adjusting equipment parameters.

Benefits of technology

It enables accurate prediction of the moisture content of the feed material for leaf re-drying, reduces the amount of unstable materials, and improves product quality stability and production efficiency.

Abstract

本发明属于烟草加工技术领域,公开了一种叶片复烤入料水分的预测方法,包括采集各级叶片风分出口的物料水分;根据日常生产测算各级风分出料量占全线出料量的比例;根据各级叶片风分出口的物料水分以及各级风分出料量占全线出料量的比例,计算各级风分出口物料的加权水分;根据各级风分出口物料的加权水分,计算打叶风分后混合物料水分;通过日常试验得到不同温湿度条件下从打叶风分后到叶片复烤入口的物料水分散失量;根据打叶风分后混合物料水分以及相应温湿度条件下从打叶风分后到叶片复烤入口的物料水分散失量,计算得到叶片复烤入料水分的预测值。根据叶片复烤入料水分的预测值对料头设备控制参数提前调整,以减少叶片复烤料头非稳态物料。
