The article describes the combined aggregate that we use in the tea-growing sector, developed on the base T-16 МГЧ, on the basis of the obtained patent GE P 2016 6491 B. The theory of similarity and dimension has been used, functional connection between the optimization parameters and the acting factors is determined and the regressive equation which is the basis the optimal working modes are selected.

There are described the types of tea bush pruning and working bodies of the pruning devices in the article. Due to the biological condition and agro-technical requirements of the tea bushes, there are carried out five different types of pruning action in the tea plantations. Therefore it is necessary to discuss a different design pruning machines. The variability of the parameters of the cross-section of tea bushes on slope is analyzed, depending on the angle of slope inclination. Also the free line width , as well as the cross-section characteristic parameters of the tea bushes – , ℎ are established.
Different types of surface formation of tea bush are characterized, including flat and semi-cylindrical forms. Their comparative analysis has been conducted. In order to increase their durability and simplifying of the construction of tea pruning and harvesting machines it is recommended to form a flat surface of tea bushes. Accordingly, It is recommended to reconstruct the existing semi-cylindrical shaped tea plantations with flat formation of the bushes surface.

Optimal parameters of extrusion process are grounded and experimental extruder for processing finedispersing tea mass is made on the basis of carried out theoretical and experimental researches. Energy and resourcesaving marchinery technology of processing granular tea of high quality was worked out and improved on the base of extruder. The main physicomechanical and chemical indicators of initial raw material and granular tea were defined. Considerable superiority of the new energy and resourcesaving technology of processing granular tea compared with the acting one according to quality and chemical composition of made product was established. Parameters of producing granular natural and multicomponent tea with additive of medicinal – nutritional raw materials were worked out at an invension level.
