Title    The design of tea processing machinery                     

Abstract Oolong tea is one of our characteristics were kind, pop a wider scope. About oolong tea processing equipment has been in ongoing research, but in terms of the current situation there is still a wide gap with other countries. Based on existing domestic and foreign tea processing machinery and equipment were studied to understand, and for equipment for processing on the quality of tea also done some analysis, and ultimately give a tea pressure kneading machine design. This program combines traditional machining exquisite detail design to meet the increased processing efficiency and ensure the quality of tea requirements, and driven by cylinder, by giving the technical parameters required to select the appropriate type of cylinder, hydraulic drive to overcome the deficiencies in the past . Combined with previous types of tea processing machinery and equipment structure, through PROE software design unfolded.
