(2) Methodologically: from flower layer to tea layer → manual blending → mechanical automatic blending;
③ Drying: cooking and baking → frying in iron pan → drying in drying cage → mechanical drying.
The existing technology is created by working people and tea science and technology workers for a long time. It is scientific to meet the objective requirements, but it also has a backward side.
1976 the Ministry of commerce released the development of automatic scenting machine, which has passed the appraisal of relevant departments and is suitable for production.
In 2002, an automatic scenting machine with a daily output of 80- 100 tons of tea was developed. It can greatly reduce labor intensity, improve sanitary conditions and improve product quality. It is an ideal scenting machine, which should be widely used to completely change the backward appearance of manual scenting of scented tea. As early as 1000 years ago, there was a way to add a spice-borneol to fine green tea. /kloc-Jasmine tea has been recorded in the 0/3rd century. In Tea Spectrum written by Rong Cheng (1592) in Ming Dynasty, the method of making scented tea was described in detail: "Sweet clover, jasmine, rose, rose, cymbidium, lotus orange, gardenia and plum blossom can all be tea. Stop tea for three times, stop flowers once, use a magnetic pot, one layer of tea and one layer of flowers, alternate with each other until full, put paper into the pot, cook it in heavy soup, take it out to cool, wrap it in paper, and bake it on the fire for later use. " During the light years of the Qing Dynasty, Lu Gu, a native of Wu, wrote in Jia Qinglu: "Zhu Lan and jasmine flowers have been collected in Shantang flower shop, and tea shops bought them as tea matching users. ..... Jasmine goes to the body and is called "claw".
In the first year of Yongzheng in Qing dynasty (1723), Suzhou jasmine tea was sold in batches in northeast, north and northwest markets. The large-scale production of scented tea began from 185 1 to 186 1 in Xianfeng period of Qing Dynasty. By 1890, the production of scented tea is more common. Scented tea is a unique tea in China.
After 1949, the production of scented tea in China has developed greatly, and the production and sales volume have increased year by year. Mainly sold to Northeast China, North China, Shandong and other places, exported to Southeast Asian countries, marketing Hong Kong and Macao.
From 1955, it was exported to Hong Kong, Macau, Southeast Asia, and Eastern Europe, Western Europe and Africa.
