The Pu'er tea optical electromechanical integration tea stalks picking machine design and application of research

In accordance with the requirements of high-quality pu-er tea, the use of light, mechanical, electrical and integration technology that have been fermented Pu-er tea collected analyzed and discussed issues such as stem. Combination of stalk sorting machin working principle, composition, and Pu-er tea, tea stems of the shape, color and so on, put forward a Pu-er tea color, shape and geometric size as the tea leaves, Pu-er tea stems the fundamental basis for sorting, focusing on light Mechatronics Pu-er tea picking machine design and application of stem were studied.

Pu-Er Tea automated fermentation system based on PLC and WINCC

This article introduces SIMTIC S7-300 programmable controller and configuration software WINCC6.0 of German Siemens, and the application in the Pu-Er Tea automated fermentation system. The system contains the upper computer and the lower computer. The upper computer is composed of PC and configuration software WINCC6.0.The lower computer is composed of PLC S7-300. Appling the system to Pu-Er Tea fermentation production, we achieved technological transformation of fermentation at Wan Hong Yang Tea Factory. This set of system and equipments have been operated for 13 months at two tea factories safely and stably, and have produced good quality and excellent taste Pu-Er Tea, received a certain economic benefits.
