The diagram illustrates two different ways of producing black tea. Overall, there are five main stages in the two processes. Although the processes have different stages, both processes start with picking fresh tea leaves and end with drying; however, they have differences in the middle steps. In the first phase of both processes is picking and withering tea leaves. Fresh tea leaves are picked by hand. They only opt for the bud and two leaves, which are on top of the tea trees; only these specific parts of the tea trees are selected to ensure the high quality. Subsequently, the tea leaves, which are carefully picked, are put on a rack and withered by a fan. During this stage, air passes through the leaves and 60% of moisture is removed. Following this, the tea leaves are divided into two different ways to manufacture, which are the traditional method and modern method. Regarding the traditional method for producing loose tea, the dried leaves are put in a rolling machine, where they are rolled flat and broken. After the rolling process, enzymes in the leaves are released. For the modern method which is used to create tea bags, the dried leaves are cut and they are torn and curled. A notable feature of this method is its quick process and creating smaller granular pieces. After being handled in two different ways, it returns to the same in the following steps. The next step is oxidation, the rolled or cut leaves are spread on tiles or cement; at the same time, enzymes combine with the air so the leaves change their color to copper. The final step is frying, these leaves after spreading on tiles are placed in an oven or hot air dryers. Then flavour and aroma are released meanwhile there is a total of 97% moisture is extracted.
