The continuous tea roasting multifunction machine, which is designed by the authors, is consisted of thermostat, pressure control device, auto-transport device and mechanical device including pans. It characterized as small volume, light weight, simple structure, convenience manipulation and tending to pipelining. This article pays more attention to the mechanizing technology in the manufacture of flat-type tea was investigated. Results showed that the quality of Longjing tea processed by the continuous tea roasting multifunction machine is better than that of processed by hand. Thus it is a high efficient machine with developmental potential and can be applied in both large scale manufactories and small workshop.
