Abstract

This patent describes a new machine which can be used to wither green tea leaves in the tea factory. The present method to wither green leaf is to place the green leaf on withering troughs and continuously blow air through the leaf. This removes the moisture in the green leaf to the desirable level. The ACTIVE WHITHERING MACHINE will remove the moisture of the green tea leaf by blowing air across the leaf at intermittent intervals. This can be done by blowing air across the leaf for a few minutes with a fan which has a lower power rating. The leaf could be allowed to idle for a few minutes and the cycle repeated again.
