Description

A simple green tea production line

technical field

The invention relates to a production line, in particular to a simple green tea production line, which belongs to the field of mechanical equipment.

Background technique

my country has a history of drinking tea for more than 4,700 years. Tea, cocoa and coffee are also known as the three major non-alcoholic beverages in the world today. With the progress of society, tea has rushed out of the country to the world, and is deeply loved by foreigners. Green tea is one of the main teas in China. It refers to the products made from the new leaves or buds of tea trees, without fermentation, and processed by typical processes such as greening, shaping, and drying. The color of its finished product, after brewing, the tea soup retains more of the green main tone of fresh tea leaves. Drinking green tea regularly can prevent cancer, lower blood fat and lose weight. With the increase of demand for tea, the traditional hand-made tea method has gradually been unable to meet the demand. In order to increase the output of green tea, people have invented various auxiliary tea-frying equipment, such as greening machine, kneading machine, microwave roasting machine and extraction machine. Fragrance machines, etc., but the existing green tea production technology still needs to be completed by man and machine, and the production efficiency still needs to be improved.
