Resumen
En cumplimiento de la normativa vigente en la provincia de Misiones, las industrias yerbateras han sustituido en sus procesos el uso de leña de bosque nativo por leña de bosque implantado y en menor medida por chip de madera del mismo origen. Cada tipo de combustible tiene una tecnología específica de quemado. El objetivo del presente trabajo fue comparar los dos métodos de secado, para evaluar la incidencia de cada uno sobre los parámetros de calidad del producto final y la eficiencia económica del proceso. Se han encontrado diferencias significativas en las propiedades fisicoquímicas al comparar los métodos utilizados. Se determinó en muestras procesadas con chip menor dispersión de valores de cada variable fisicoquímica. Los costos de producción se redujeron un 29,73% respecto de la leña de bosque implantado. Se determinó que con chip se logra un producto con mejores atributos de calidad y procesos productivos económicamente más eficientes
In compliance with the regulations in force in the province of Misiones, the yerba mate industries have replaced their processes using native wood for firewood planted forest and to a lesser extent chip of wood of the same origin. Each type has a specific fuel burning technology. In compliance with current regulations in the province of Misiones, the yerba mate industries have substituted in their processes the use of native forest firewood by implanted forest firewood and to a lesser extent by wood chip of the same origin. Each type has a specific fuel burning technology. The aim of this study was to compare the two methods of drying, to assess the impact of each on the parameters of product quality and economic efficiency of the process. We found significant differences in physicochemical properties by comparing the methods used. It was determined less dispersion of values of each physicochemical variable in samples processed with chip. Production costs were reduced by 29.73% compared to forest firewood. It was determined that with chip a product of better quality and more efficient economically productive processes is achieved.
