Abstract

La presente invención se dirige a un sistema que satisface esta necesidad. El sistema comprende un recipiente de digestión, una entrada para introducir alimentos biodigeribles dentro del recipiente de digestión, una entrada para introducir un gas dentro del recipiente de digestión, y una entrada para introducir las bacterias dentro del recipiente de digestión de un alimento biodigerible. Existe una salida de alimentación digerida para la alimentación digerida. El sistema incluye un sistema de control para cambiar los contenidos del recipiente de digestión de la operación aeróbica a la operación anaeróbica o anóxica sin cambiar las bacterias en el recipiente de digestión. El sistema también puede cambiar los contenidos del recipiente de digestión de la operación anóxica o anaeróbica a la operación aeróbica sin cambiar la bacteria en el recipiente de digestión. El cambio en los contenidos puede ocurrir en menos de 45 minutos, y típicamente en aproximadamente 5 a aproximadamente 30 minutos. El sistema típicamente incluye una válvula para controlar la introducción de oxígeno conteniendo gas en el recipiente de digestión a través de la entrada del gas, en donde la válvula es controlable por el sistema de control.De preferencia existe una tina de remojo para remojar el alimento antes de la introducción del alimento al recipiente de digestión.Típicamente el sistema de control se adapta para mantener los contenidos del recipiente de digestión en una temperatura elevada de al menos 60°C para matar los patógenos.Dependiendo del alimento, puede existir una zona de pulverización para pulverizar el alimento antes de la introducción dentro del recipiente de digestión.El producto del recipiente de digestión puede separarse en un separador para producir una fase predominantemente sólida y una fase predominantemente líquida. La fase sólida puede clarificarse usando un clarificador. En un método de acuerdo con la presente invención, el alimento biodigerible se introduce dentro de una zona de digestión. La bacteria apropiada para la digestión del alimento bajo condiciones aeróbicas, anaeróbicas y anóxicas también se introduce dentro de la zona de digestión. Los contenidos de la zona de digestión pueden modificarse de la operación aeróbica a la operación anóxica o anaeróbica o viceversa, sin cambiar la bacteria en la zona de digestión. Por ejemplo, para cambiar de operación aeróbica a anaeróbica o anóxica, la cantidad de oxígeno siendo introducido en la zona de digestión puede reducirse o completamente eliminarse. También es posible cambiar de atrás hacia adelante entre operación aeróbica y anaeróbica o anóxica.La zona de digestión puede tener una fase líquida salobre con una densidad de más de 1 y más de aproximadamente 1.2 y más típicamente más de aproximadamente 1.12. El alimento biodigerible puede tener una porción líquida salobre con una densidad de aproximadamente 1.009 a aproximadamente 1.012.Opcionalmente la alimentación puede remojarse en una zona de remojo antes de la introducción dentro de la zona de digestión. La zona de remojo puede mantenerse en una temperatura suficientemente elevada para matar los patógenos. Como se necesite, puede agregarse agua a la zona de remojo y opcionalmente bacterias. Un acelerante puede introducirse dentro de la zona de digestión. El acelerante puede seleccionarse del grupo que consiste de una fuente de nitrógeno, una fuente de fósforo, una fuente de potasio y una fuente de carbono.De preferencia, la bacteria es al menos un organismo de las familias Bacillus subtillis, Bacillus sphaericus, Bacillus megatarium, Bacillus licheniformis, Enterobacter sakazakii, Bacillus coagulans, Bacillus cereus, Bacillus pasteurii, Bacillus cirroflagellosus y Bacillus pumilus. De preferencia existe al menos un organismo de cada una de las familias.Un amortiguador puede introducirse en la zona de remojo y/o la zona de digestión. El amortiguador puede ser uno o más de un compuesto seleccionado del grupo que consiste de CaCO3, MgCO3, MnO, NaOH, y KOH.Típicamente, el alimento digerido retirado contiene agua, y el agua puede removerse del alimento digerido. Cuando un amortiguador se introduce dentro de la zona de digestión y/o la zona de remojo, el amortiguador puede contener agua removida del alimento digerido retirado.El gas retirado de la zona de digestión puede ser un gas combustible. Cuando el gas retirado contiene dióxido de carbono, el dióxido de carbono puede usarse para soportar el crecimiento de algas.Es deseable detectar la composición del gas retirado para controlar el proceso de digestión en la zona de digestión con el sistema central. El proceso en la zona de digestión puede controlarse mediante cambiar al menos uno de la temperatura de la zona de digestión, agregar la bacteria a la zona de digestión, cambiar el pH en la zona de digestión, cambiar el tiempo de residencia en la zona de digestión, cambiar la presión de la zona de digestión y cambiar la composición del gas dentro de la zona de digestión.Es posible formar un pastel de la fase predominantemente sólida, en donde el pastel puede quemarse como un combustible.
