A Research Report On The Technological Innovations Of Tea-Manufacturing Mechanization

This dissertation,including every task of this research,has been accomplished under my direction of my supervisor , Pro. Zhou Zhirong. All the research has been complemented and completed in 78 towns, 315 villages, 282 tea plantations and tea manufacturers in different counties as Nanzhen, Mianxian, Xixiang, Ningqiang, Chenggu, Zhengba, Lueyang, and Yangxian which are all major tea-grown areas and tea-manufacturing places in Hanzhong city. After quite a few years'experiments and hard work, a more efficient set of mechanical processing technologies ideal for Hanzhong green-tea manufacturing has been found out . The procedure is described as: to spread out and air the fresh tea leaves in grades---to treat tea leaves for green colour preservation---to rub and twist---to roll and make the fresh base---to spread out and air the base --- to fry the base---to spread out and dry the base again---to roll the base another time till dry enough--- to spread out and dry--- to pack it up and the products are finished. The technological parameters are described in this dissertation. The other set of mechanical processing technologies ideal for Hanzhong famous-tea manufacturing has also been sought out, and the procedure is described as: to spread out and air the fresh tea leaves in grades--- to treat tea leaves for green colour preservation---to breeze-dry---to form--- to spread out and dry once again--- to cure for the first time--- to spread out and dry again--- to cure for the second time---to spread out to dry for one more time--- to pack it up and the products are finished. The technological parameters are also enclosed in this dissertation. It has been found out that when large amounts of green tea have been manufactured by modern-type machines , the costs of famous tea and large amounts of green-tea can be cut down RMB 20.83 yuan and 3.14 yuan per kilogram respectively than manual operations and old traditional machines. In manufacturing large amounts of green-tea, the cost of per kilogram of dry green-tea can be saved RMB 0.09 yuan by the modern-type machines. While the quality is more stable than before, the efficiency made by the new-type machines for manufacturing famous-tea products has been improved by 8.6 times than manual operations, more than 0.5 times by machines for manufacturing large amounts of green-tea than the old machines; which have proved an important breakthrough and great innovation, even a technological revolution in the manufacturing of green-tea, famous-tea, and large amounts of green-tea in Hanzhong tea industry. Over the past few years, 35 different modern-types of 932 tea-manufacturing machines in total have been popularized and used, which achieved an economic benefit of RMB 279,000,000 yuan. Today, the popularization and use of the technologies has been playing an important role in tea-manufacturing in Hanzhong, and it has also vigorously promoted our famous-tea manufacturing in terms of amounts, grading, and scales. In addition, both the quality of large amounts of green tea and the whole level of industralization in green-tea manufacturing have been improved so much that all the remarkable economic, social, and ecological benefits can be successfully acquired. Thanks to the modern technologies, a rapid progress has been made and the developments in tea manufacturing industry are being promoted not only in Hanzhong but the whole province ,and even in the neighboring tea plantations as well.
