Green tea is the least processed among the six types of Chinese tea.  It undergoes the least amount of oxidation.  The shorter processing gives green tea a lighter flavor than black tea.  Also result in the high catechins content, which is why it is so good for you.
It mainly has the following three steps:
Steamed or Pan Fried – Rolling (Rounian) – Drying

After the tea leaves are picked, it should be thinly spread for 2-3 hours (depend on different teas) in order to reduce the water content. 

Select: remove yellow leaves and other debris

Steamed or Pan Fried

This step is the crucial technique for quality.  Shaqing has four important goals:
to get the proper color, smell and taste of Green Tea by completely destroying the activity of enzymes in fresh leaves and stop the enzymatic oxidation of polyphenols;
to give off grassy smell in order to release the aroma;
to evaporate part of the water in the fresh leaves to soft the leaves and enhance toughness to make the next step rolling easier;
to promote the transformation of inclusions, and promote the formation of green tea.

This kind of electric pan can most contain 400g leaves.

Rolling (Rounian)

The purpose of Rounian is to make the shape tight in order to make the next step drying easier. As well as destructing of leaf tissue to make better quality for easy brewing out the tea liquor.
