Ideal Temperature and Humidity Levels for Proper Tea Processing

Multiple COEUS-WIFI wireless temperature and humidity sensor, gateway and platform constitute the wireless monitoring system. The system continuously monitors the temperature and gives pinpoint accurate alerts/ local indications through the app to extract the tea on point. By following the instructions, the quality of the tea can be improved.

The history of tea processing is a long and gradual story of refinement. Generations of growers and producers have perfected the way of manufacturing tea. There are two to seven procedures are involved in the processing of fresh tea leaves, such as withering, fixing, oxidation, fermentation rolling, drying, and aging. Each of these procedures required high accuracy and high stability in temperature and moisture control to avoid spoilage due to excess moisture and fluctuating temperatures.

Among all these processes fermentation is one of the most important processes where tea leaves change color and smell. It is a complex chain of biochemical reactions that take place during the fermentation process and once such changes reach their optimum point, the process should be stopped. The physical parameters that affect the fermentation process are relative humidity and temperature. Thus control of these physical parameters will be very useful to maintain proper fermentation conditions to have desired quality of tea. An ambient relative humidity of 95-98%RH at 20-26℃ is required to maintain fermentation, and even a small fluctuation in temperature and humidity level will affect the process, reducing yield. 

Featuring a wide operating temperature from－20℃ to +50℃, the COEUS-WIFI wireless temperature and humidity monitor can be installed in the fermentation room to monitor the internal temperature and humidity, which makes sure the tea leaf fermentation process is under the best conditions. Multiple wireless temperature and humidity monitor, gateway and platform constitute the wireless monitoring system. Gateway will receive all sensing data, and then it forwards all data to Freshliance Cloud. Users can not only see visualized data on mobile phone but also get real-time alarms from anywhere. The system continuously monitors the temperature and gives pinpoint accurate alerts/ local indications through the app to extract the tea on point. It sends real-time emails or SMS alerts and LED indications on shifting the tea leaves from withering and fermentation in the right condition. By following the instructions, the quality of the tea can be improved and the energy cost can also be saved significantly.
