Abstract: Take the domestic tea processing machinery as the main body, a set of man-machine interface automatic processing line and the control system for the manufacture of roasted green tea was developed by the object-oriented multi-layer architecture technology “Delphi 7.0”. The objective of the automatic processing line characterized with accurate processing parameter control, the dynamic processing condition with real time display, the processing data with automatic saving and the automatic-control and hand-control can be free-cut. With the roasted green tea automatic processing platform, fixation, rolling and drying and so on were investigated, and a set of standard processing parameters were proposed initially.

Key words: atomatic, production line, roasted green tea
