Some methods to detect tea states in real time during tea manufacturing process were showed in succession to the previous report. The estimate of the moisture content of tea leaves by the electric resistance of tea leaves and the measurement of the volume of tea leaves as a shaping index in final rolling process in which the tea leaves are shaped simultaneously with drying are described in this report. We also discussed the influence of the measurement error to the estimate of the moisture content of tea leaves on the moisture content estimate by the absolute humidity difference between supplied air and exhaust air which was showed in the previous report.
