Achieve optimal 95-98% RH levels in your tea fermenting rooms. Our advanced misting systems ensure superior tea quality, reduced energy costs, and consistent production year-round.
A moist environment promotes tea development, and the proper relative humidity level is critical for converting the harvested leaves into quality tea during manufacturing. With our advanced Humidification System, temperature and moisture can be controlled significantly during oxidation.
This cycle creates the ideal conditions for polyphenols in wilted leaves to form theaflavins, thearugibins, and other mixtures that contribute to the distinct flavours and colours of teas.
To maintain proper fermentation, a relative humidity of 95-98% RH at 20-26°C is required. Even a minor decrease in humidity will influence the process, decreasing tea production quality.
