For a long time medicinal plants were the main resource available to treat diseases. For this reason, numerous studies were carried out on these plants and investigations on the use of their products and derivatives. The Chinese konoca (Xenophyllum poposum) is a native plant that grows wild in the Peruvian Andes at more than 4400 meters above sea level, it is widely used as a natural infusion for digestion. The purpose of this work was to perform a mathematical modeling during the dehydration process of the Chinese konoca (Xenophyllum poposum). For this, the dehydration kinetics evaluation of this plant was carried out at 60°C and 80°C, during 480 and 600 minutes, where the moisture loss measurements were made. Dehydration speed graphs were obtained as a function of time, temperature and humidity, with these data a mathematical modeling of each treatment was performed to describe the trend in the dehydration curves. Resulting in a second degree polynomial model which showed the best goodness of fit in the kinetics of hot air drying, % H = a - b θ + c θ 2. In addition, the modeling was done to predict the equilibrium time in the decrease humidity, deriving the previous equation, θ = b / 2c.
