Embodiment 1

[0011] Spreading After picking the fresh leaves of wintersweet, spread them thinly on a clean bamboo plaque immediately, with a thickness of 3-5cm, 2-3 kg per square meter, and should not exceed 8cm. The spreading time depends on the temperature and air humidity, usually 3-6 hours, and it may also need to be spread for 6-18 hours in low temperature and rainy weather after harvesting. It needs to be turned frequently during spreading to avoid deterioration caused by local heating. It is advisable to lose 15-20% of the water when the fresh leaves are wilted visually, the leaf surface loses its luster, and the leaf color turns dark green and fragrant.

[0012] Put the spreaded wintersweet leaves into the drum killing machine, set the temperature at 280°C, and take about 5 minutes. The degree of killing is suitable for old killing. It is required that the greening leaves have bursting points, the leaves feel fragile, and the stems are soft. Not easy to break.

Abstract

The invention discloses a method for preparing wintersweet tea, comprising following steps: laying fresh leaves-> water removing-> twisting leaves-> curing-> twisting leaves again-> rolling and drying-> selecting-> curing and drying. It is characterized in that it comprises a homogenous wetting step after removing water from fresh leaves. The high-temperature water-removing treatment in a short time ensures the water-removing effect, and the laying and wetting process effectively improves the crisp condition for dry wintersweet tea, and ensures the intact leaves during twisting process and improves the wintersweet tea quality.
