摘要

介绍了一种用于绿茶生产干燥过程的微波水分计。它可以在干燥的基础上测量含有40%至100%水分的绿茶叶子。它是一种9.4 GHz波的传输类型。为了消除层厚的变化，控制样品的重量。水分含量由微波衰减与叶片重量之比得到。用计算机对数据进行平均，水分含量的测量误差为水分值的3%。它比工厂中实际使用的由熟练工人的手指感觉的传统测量误差要好。

Microwave moisture sensing system in drying process for green tea production

A microwave moisture meter used in a drying process for green tea production is described. It can measure the leaves of green tea containing the moisture of 40 to 100 percent in dry basis. It is a transmission type of 9.4 GHz waves. To eliminate the variation in the layer thickness the sample weight is controlled. The moisture content is obtained from the ratio of the microwave attenuation to the weight of the leaves. Averaging the data with a computer the moisture content were measured in the error of 3% of moisture values. It is better than the error of the conventional measurement by the feeling of a skilled workman's fingers actually used in factories.<>
