The traditional Pu'er tea fermentation is uses the man-power to moisten naturally in the workshop piles the fermentation, this fermentation way cannot guarantee that in the Pu'er tea fermentative process the humidity uniformity, produces the workshop and the Fermentation plant to the Pu'er tea carries on the design and the research, the microorganism technology, the machine-finishing technology and the electric control technology merges into one organic whole, causes the Pu'er tea the production standardization, and has the scientific nature. The Pu'er tea fermented the clear purification workshop to unify the technology which the tradition fermented, used modernized the examination control technology and the equipment, by humidity sensor, PLC master control equipment, computer constitutions and so on processing system, Canadian wet equipment and supervisory system. This article through constructs the Pu'er tea to ferment the clear purification workshop, carries on the controlto the workshop ambient humidity, causes the Pu'er tea to be stable in fermentative process environment, and has carried on the production testing under this kind of environment, obtains the experimental correlation data and carries on processing, discovers the Pu'er tea fermentation humidity from the tentative data to form the influence to the Pu'er tea quality some rules, ferments the formalization production for the Pu'er tea to provide the corresponding scientific parameter.

This paper carried out the research on Pu'er fermentation automatic control process, using engineering and biotechnology and the application of parameters in the critical link of Pu'er tea quality formation. Pu'er tea fermentation plant design were optimized; the tide proportion before Pu'er tea fermentation had been carried out accurate quantitative and automatic control study; the temperature and humidity of Pu'er fermentation plant and inside the heap had been real time on-line automatic detected and control using PLC in Pu'er tea fermentation process; the series of projects such as structure and materials of Pu'er tea fermentation container had been carried out research and development. The applications of research results in the production improved the quality of our products and production efficiency.
