Tea leaf moisture measurement and drying control

Measurement target example: Tea leaves

• Measurement target: 5-15% HO
• Benefits of measurement: The taste and aroma of tea are greatly affected by temperature and moisture during the drying process, so moisture measurement is necessary for quality control.
• Point; In the moisture meter before drying, the speed of the conveyor belt is control from the loading moisture. In addition, the moisture meter after drying control feedback on the deviation of the target moisture. Due to the long drying time and large delay (waste) time, intermittent control and deviation integration methods are performed by PLC, which can also be used to deal with wasted time, and quick and accurate moisture control can be performed.
