本文简述了快速失重法及其实验装置和物料的极限烘干温度,得出了极限烘干温度下粉粒物料水分蒸发的数学模型,通过快速失重法和标准法测量物料水分的比较,证明了快速失重法是一种可靠、正确的测量物料水分的方法,测量精度为±0.1%含水量(绝对误差)。基于研究,研制出在线快速失重式粉粒物料水分仪,给出了仪器的组成、技术指标和特点,该仪器经在线使用,取得良好效果。
In this paper, the rapid drying method of weight loss and its experimental drying equipment and the drying temperature of the material were briefly introduced. The mathematical model of the moisture evaporation of the powder and granular material at the ultimate drying temperature was obtained. The comparison between the fast weight loss method The fast weight loss method is a reliable and accurate method for measuring the moisture content of materials with a measurement accuracy of ± 0.1% moisture content (absolute error). Based on the research, the on-line rapid weight loss particle material moisture meter was developed. The composition, technical index and characteristics of the instrument were given. The instrument was used online and achieved good results.
