Procedures involved in the manufacture of Tea

The young leaves are carefully plucked from the top most portion of the tea bush. The young shoots are key to quality tea.


The plucked leaves are then brought to the Factory where it is spread on the withering troughs. By using fans to blow hot and cold air the moisture in the leaf is reduced. Withering takes about 14 to 16 hours.


The withered leaves are then passed through a Rotorvane where the leaves are raptured, thus pre-conditioning the leaves. It is then passed through CTC machine where the leaves are cut thrice by the rollers.


Oxidation takes place which could last for 1 hour to 1 hour 30 minutes depending upon the climatic condition. During fermentation the crushed green leaves changes its colour to coppery-red in colour.


Fermentation is arrested by drying, where the fermented leaves are fed into the dryer in a manner where the temperature varies from 120°C to 128°C. The time taken for drying is around 20 minutes. The tea turns black in colour.


The black teas are then sorted by passing through sorting machines where meshes are used of various sizes. Different grades are obtained from different mesh sizes.


The Graded teas are then packed in poly liners which are then put into Jute bags and stitched to prevent any air from entering the bags.
