<p>PROBLEM TO BE SOLVED: To provide an apparatus which measures the amount of water component evaporating in the processes prior to rough rubbing, originally contained in tea leaves in a large amount of 100% or more on dry weight basis.SOLUTION: The supply amount of raw tea leaves is kept constant with a supply amount control device, and the flow rate of raw leaves is then measured. The measurement set value of a measurement pool disposed immediately in front of a batch-type rough rubbing machine and the residence time in the pool are measured. Alternatively the flow rate of tea leaves is measured with a measuring conveyor disposed immediately in front of a continuous-type rough rubbing machine. By means of the measurements, the flow rate of raw leaves when supplied and the flow rate of tea leaves immediately before the rough rubbing process are compared, so that the amount of water component evaporating in the period is measured.</p> |
