Leaf receipt Process:
Tea factory software from OneBusiness ERP has successfully implemented in Tea factories in Tamil Nadu, India. Factories receive green leaves from growers from various estates.
A factory staff with a mobile application will enter various parameters while entering the receipt of the goods. Fresh leaves usually contain about 73-80% of moisture.
The leaves spread on the withering tables. The staff will start the ventilation process tables from beneath.
Factory staff allow 12to 24 hours of withering the leaves’ moisture content will go down to about 60-65%. The quality of the tea will very much depend on the withering process.
Tea factory staff will feed the withered green leaves into a rolling machine. –
What is a Rolling Process?
Is the process of twisting and rupturing green leaves to expose more surface area for bringing out the juices to the surface of the leaf.
Rolling is done for approximately about 30 to 40 minutes.
A mesh will separate unrolled leaf for recycling. The rolled leaf will enter the fermentation process.
How much pressure do we need for this process?
The experienced staff will fix around 2 to 3 bar of pressure and 30 to 60 minutes to realise great results.
The fermenting process will take 2 to 6 hrs. The transition of black tea will develop its new flavour and aroma. The original bitter taste will vanish as a result of the fermentation.
The most critical step in tea manufacturing is drying tea leaves.
We have to be careful in this step to stop spoiling the whole production lot. The drying temperature would be around 90 to 95. The residence time and the temperature will bring down the moisture content to 3 to 4 %.
The hot conveyor belt speed will determine the residence time.
Factories use Taylor mechanical sieves to sort the tea according to different leaf grades.
