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.The present invention is directed to a system that satisfies this need. The system comprises a digestion vessel, an entrance to introduce biodigestible food into the digestion vessel, an entry to introduce a gas into the digestion vessel, and an entry to introduce bacteria into the digestion vessel of a biodigestible food. There is a digested power outlet for digested power. The system includes a control system to change the contents of the digestion vessel from the aerobic operation to the anaerobic or anoxic operation without changing the bacteria in the digestion vessel. The system can also change the contents of the digestion vessel from the anoxic or anaerobic operation to the aerobic operation without changing the bacteria in the digestion vessel. The change in the contents can occur in less than 45 minutes, and typically in about 5 to about 30 minutes. The system typically includes a valve to control the introduction of oxygen containing gas into the digestion vessel through the gas inlet, where the valve is controllable by the control system. Preferably there is a soaking tub for soaking the food before the introduction of the food into the digestion vessel. Typically the control system is adapted to maintain the contents of the digestion vessel at an elevated temperature of at least 60 ° C to kill the pathogens. Depending on the food, there may be an area of spray to spray the food before introduction into the digestion vessel. The product of the digestion vessel can be separated into a separator to produce a predominantly solid phase and a predominantly liquid phase. The solid phase can be clarified using a clarifier. In a method according to the present invention, the biodigestible food is introduced into a digestion zone. The appropriate bacteria for digestion of food under aerobic, anaerobic and anoxic conditions is also introduced into the digestion zone. The contents of the digestion zone can be modified from the aerobic operation to the anoxic or anaerobic operation or vice versa, without changing the bacteria in the digestion zone. For example, to change from aerobic to anaerobic or anoxic operation, the amount of oxygen being introduced into the digestion zone can be reduced or completely eliminated. It is also possible to switch back and forth between aerobic and anaerobic or anoxic operation.The digestion zone may have a brackish liquid phase with a density of more than 1 and more than about 1.2 and more typically more than about 1.12. The biodigestible food may have a brackish liquid portion with a density of about 1,009 to about 1,012. Optionally, the feed may be soaked in a soaking zone before introduction into the digestion zone. The soaking zone can be kept at a temperature high enough to kill the pathogens. As needed, water can be added to the soaking zone and optionally bacteria. An accelerator can be introduced into the digestion zone. The accelerator can be selected from the group consisting of a source of nitrogen, a source of phosphorus, a source of potassium and a source of carbon. Preferably, the bacterium is at least one organism of the Bacillus subtillis, Bacillus sphaericus, Bacillus megatarium families. , Bacillus licheniformis, Enterobacter sakazakii, Bacillus coagulans, Bacillus cereus, Bacillus pasteurii, Bacillus cirroflagellosus and Bacillus pumilus. Preferably there is at least one organism of each of the families. A buffer can be introduced into the soaking zone and / or the digestion zone. The buffer may be one or more of a compound selected from the group consisting of CaCO3, MgCO3, MnO, NaOH, and KOH. Typically, the digested food removed contains water, and the water can be removed from the digested food. When a buffer is introduced into the digestion zone and / or the soaking zone, the buffer may contain water removed from the digested food removed. The gas removed from the digestion zone may be a combustible gas. When the removed gas contains carbon dioxide, the carbon dioxide can be used to support the growth of algae. It is desirable to detect the composition of the removed gas to control the digestion process in the digestion zone with the central system. The process in the digestion zone can be controlled by changing at least one of the temperature of the digestion zone, adding the bacteria to the digestion zone, changing the pH in the digestion zone, changing the residence time in the zone of digestion. digestion, change the pressure of the digestion zone and change the composition of the gas within the digestion zone. It is possible to form a cake of the predominantly solid phase, where the cake can be burned as a fuel.
