El presente trabajo de investigación tiene como finalidad determinar los coeficientes de difusión efectivo D y convectivo de transferencia de masa hm en el secado del ají panca (Capsicum Annuum L). Para esto se realizaron pruebas del secado del aji panca a temperaturas constantes de 40°C, 45°C, 55°C, 66°C y 75°C. Obteniéndose curvas experimentales de la humedad en función del tiempo; las cuales son ajustadas al modelo teórico (ecuación de Fick). El uso de métodos numéricos nos permite obtener las raíces positivas de la ecuación trascendente; con estos valores se obtienen los coeficientes. Siendo este método de suma importancia para el secado, porque nos da la información en qué rango de temperaturas puede secarse el ají panca. Los resultados obtenidos muestran que a temperaturas de 50ºC a 55ºC las curvas experimentales y teóricas tienen un buen comportamiento. Lo q...

In this work, tests were carried out on the drying of the ají panca in a forced air solar dryer using fifteen vacuum tubes (Heat pipe), a closed cabin where the product is placed and a squirrel cage turbine that is fed by a system of two photovoltaic panels of 50 W each. The heated air is driven by the turbine from the vacuum tubes to the product in the cabin, in this work the unidimensional Fick difusion equation and numerical methods were used to determine the mass transfer coefficient 2.61 x 10- 9 ms-1 and the effective diffusivity coefficient 1.52 x 10-10 m2 s-1 and it was concluded that the drying temperature of is 55 °C is the one that best fits the results estimated by the model. The solar vacuum tube dryer is capable of maintaining an operating temperature between 50 °C to 55 °C for an irradiance of 450 to 1100 W /m2 between 9:30 am and 2:30 pm, under these conditions, in two...

In this work, tests were carried out to determine the calorific power of briquettes of alpaca and ichu manure and binder; the proportion of the mixture is 80% alpaca manure, 18% ichu, 2% lime and water in proportion to the manure. The results show the maximum temperature reached by the briquette under study is 500 ° C measured with an infrared thermometer and estimated calorific power for these briquettes 4318.18 cal / g. Due to the results obtained, the resulting briquettes can be used as an alternative and economical fuel that is also friendly to the environment. Alpaca manure at 4000 meters above sea level is not used as fertilizer for agriculture in the town of San Antonio de Chuca-Imata.
