Description

Tea making process and equipment by conductive production all-weather production, fully enclosed baking

The invention belongs to the technical field of tea processing technology and equipment, and particularly relates to a whole-weather production and fully enclosed baking tea making process and equipment thereof through electrical conductivity.

Tea refers to the finished product made from the new leaves of tea tree, without oxidation, by the typical process of killing, twisting and drying. Tea has a long history and is a traditional Chinese drink. In the prior art, there are many methods for processing tea, and green tea generally includes sorting-killing-squeezing-forming-drying-commodity. Fragrant black tea, oolong tea, and alpine green tea generally include sorting - shaking green, treading green, greening or greening - spreading green - killing blue - repeating, smashing, unwinding, spreading, drying, spreading green - goods . However, in the world of tea, during the baking process, more than 50% of the aroma of the tea leaves in the processing process is followed by evaporation of water, alcohol and enzymes. Because most of the tea fragrance is lost, the tea can ensure the color of the tea soup after being fried. However, during the tasting process, people find that the natural tea fragrance in the tea soup is running low. The last liquefied formula of the finished product is only roasted. The tea leaves are fragrant, but further destroy the natural plant fragrance of the tea, which greatly reduces the enjoyment of tea enjoyment.

China’s Heluo people (Southern Han Chinese) discovered that the surface of tea leaves was destroyed by treading, shaking, cyan, greening, and throwing green more than a thousand years ago. The infiltration of leaf juice and air produced wonderful changes. Aroma creates a semi-green oolong tea. Three hundred years ago, Heluo people in Anxi created Tieguanyin, a 70% green tea with green leaves and red fragrant edges. Heluo people in Taiwan created mountain green tea in recent years. Almost all of the Rocky Tea (Southern Han Dynasty, Heluo's Rocky Tea, 'Yi' is the waterside, the rocky cliff in the fog), still depends on the experience of the workers in the production process, the tea is in the process of cooking and frying The strength of the work depends entirely on the experience accumulated by the workers for many years. During the production process, it is greatly affected by the weather and climate. The artificial pressure cannot control the pressure, humidity, temperature and baking of the wet fresh leaves. Gas dew point, if the weather and rainy season is long, it is very likely that the high-quality new tea produced in the same year will be reduced, the natural plant fragrance of tea will be lost, and the tea farmer's economy will suffer huge losses.

The technical problem to be solved by the present invention is to overcome the shortcomings of the existing Rocky tea technology, and to provide a whole-weather production, fully enclosed baking tea making process and equipment thereof by using a special process and processing equipment, without removing red edges.
