The present invention abstract describes the steps of a process for the preparation of black tea and the respective end product, wherein, in the initial step of the proposed process for producing black tea, the young yerba mate leaves (buds) are subjected to withering for a certain time. Next, the already withered leaves are rolled; next, the fermentation is carried out, and after such fermentation, drying and segregation are performed.

The following invention specification relates to the process for the preparation of black tea made from yerba mate (ilex paraguariensis), and the respective end product.
It is known that the use of yerba mate as food is restricted to some regions of South America, where its largest consumption is in the form of mate, a cultural habit. The present product has the potential to compete for consumers worldwide, as it does the Camellia sinensis green tea and the black tea, and reach consumers who the mate would not be able to reach.
In order to use the yerba mate, several drying processes are known, for example, those described in PI 9504075-7 comprising a construction having a heat draft system through modular upper outlets with a butterfly valve on each chimney. Inside the oven, two belts are moved in series, in the opposite direction, being one upper belt and one lower belt, and the belts are unloaded by means of load dumpers, consisting of a bladed shaft rotating in the same direction as the belts. A deflector plate directs the yerba mate from the upper belt to the lower belt and to a discharge outlet guiding the yerba mate from the lower belt to the outlet conveyor belt. The furnaces conduct the heat generated to the oven by means of ducts that split into two branches, where a distributor receives the yerba mate from a belt.
The embodiment of the invention proposed in this specification is achieved by describing the different steps required for carrying out the present application, such that it can be fully reproduced by means of appropriate technique, thus allowing full characterization of the claimed process functionality.
Based on the different steps described that express the best or preferential way to carry out the process now devised, the descriptive part of the report is based, thus clarifying aspects that may have been presumed, so as to clearly determine the protection now claimed.
These operations may vary, provided that they do not depart from the initially claimed subject matter.
