Know the steps involved in green tea manufacturing:

The most important steps involved in green tea manufacturing are as follows:

Step 1: Plucking

Harvesting process in tea industry is known as plucking. It is done by picking the tender apical shoots which includes the terminal bud along with 2/3 adjacent leaves. The picker nips off the tea shoot with use of the thumb and forefinger. This standard of plucking is necessary to ensure the quality and taste of tea. In some bigger gardens mechanised plucking is performed in which this standard is difficult to maintain as machine plucking results in more broken leaves and partial buds. The leaves are carried in open trailers from the garden to the factory for manufacturing. They are weighed before starting the manufacturing process. withering in green tea manufacturing

 Step 2: Cooling

In order to cool down the leaves which accumulate heat as a result of stacking, the tea leaves are spread evenly on a trough or on the floor. Small amount of water is sprinkled to cool and freshen up the leaves faster.

 Step 3: Roasting or Pan Frying

As soon as the leaves cool down and regain freshness, they are fed into the roasting machine. Green leaves are then processed for around 20 minutes in batches in the roaster.

Step 4: Re-cooling

The hot roasted leaves are then spread evenly over the perforated troughs to cool. As blower supplied cool air passes across the perforated trays trough from below, the leaves release the heat and cools down considerably and becomes ready for the next operation.

Step 5: Drying

The drying process serves few vital purposes. First it stops both the enzymic reaction and the oxidation. Secondly drying gives birth to a stable product that can be stored for a certain period without any noticeable degradation in quality. Last but not the least, for green tea drying process is more important because green tea acquires some desirable characteristics like flavor and color during the drying process. green tea manufacturing - a dryer in operation

The roasted leaves are then fed to the dryer. The coal fired dryer dries up most of the roasted leaves to food grade green tea. However a small portion of the leaves may not dry adequately. Sufficient care should be taken to ensure proper degree of drying and to eliminate any possibility of over-cooking of the leaves.

Step 6: Pre-sieving and final sieving

As the fully dried-up leaves are finer in size than insufficiently dried coarse leaves, the fine particles pass through the perforation and the spill i.e. undried coarse leaves are sent for further tea manufacturing - a sorting machine in operation

After the drying is over, green tea is ready. Then it is processed for final sorting. The made tea leaves pass through an array of sorting machines that segregates the produce as per their size. The whole unbroken leaves with highest amount of silvery buds and almost no stems mixed are of the topmost quality. The presence of more buds ensures better quality by adding sweetness and giving tea the most health benefits. Medium-grade tea consists of some broken leaves with stems mixed in, and less quantity of white buds. The smaller ones with all broken leaves and no buds are of low quality. green tea manufacturing- a cup and a pot with green tea
