How To Withering Tea Leaves On Rainy Day?

2022-04-22 13:57:53

The traditional natural withering takes a relatively long time, which affects the production efficiency. Therefore, manual intervention can be adopted, and the temperature and humidity can be strictly controlled through the hot air dehumidification device --- tea withering machine to accelerate the evaporation of water on the surface of the fresh wet tea leaves.

In addition, after the rainwater leaf enters the factory, special machinery, such as a withering mechanical treatment device, can be used to heat and blow the tea leaves to evaporate the water on the surface of the rainwater tea leaves and in the pores, so as to realize the rapid and uniform dehumidification of the tea leaves. The amount of the content, the amount of air supply is dynamically adjusted, and the dynamic contact time between hot air and rainwater leaf, the amount of hot air and the temperature are strictly adjusted, so that the water on the surface of the tea absorbs heat and evaporates quickly within 2-3 minutes, so as to quickly remove the surface of the tea. The purpose of dehydrating rainwater wet tea leaves, keeping fresh and keeping green, and it is fast, efficient, energy saving and low consumption.

Although the harvesting of rainwater wet tea leaf does not occupy the advantage of "time of day", as long as it is handled properly, it will still have a good performance. Tea producers can flexibly choose the treatment method of rain green according to their own conditions, so as to reduce the impact of rainy days on the production of spring tea.
