Device for processing substances, in particular digestate and digestate mixtures

Abstract

A device for processing digestate or digestate mixtures ( 2 ) includes a floor ( 3 ) on which is to be places the digestate ( 2 ). The floor ( 3 ) is designed gas-permeable. The device includes an inlet device ( 4 ) that can be connected to a line ( 6 ) for introducing a gaseous medium into the floor ( 3 ). The inlet device ( 4 ) is designed such that a gaseous medium can flow through at least part of the area of the floor ( 3 ) for purposes of aerating the digestate ( 2 ) and heating the digestate ( 2 ) if the gaseous medium is heated. At least one heating element ( 5 ) is provided in the area of the floor ( 3 ) to provide heat to the digestate.

1 . A device for processing digestate or digestate mixtures ( 2 ), said device including a floor ( 3 ) for placing the digestate ( 2 ), whereby the floor ( 3 ) is gas-permeable, and whereby the floor ( 3 ) includes an inlet device ( 4 ) that can be connected to a line ( 6 ) for introducing a gaseous medium into the floor ( 3 ), said floor ( 3 ) configured such that the gaseous medium can flow through at least parts of the floor ( 3 ) for aerating the digestate ( 2 ), whereby a heating device ( 6   b ) is provided in the line ( 6 ) for the purpose of heating the gaseous medium that is flowing through the line ( 6 ), characterized in that at least one heating element ( 5 ) is provided in the floor ( 3 ) of the device, said heating heating element ( 5 ) configured and arranged to be in contact with said digestate material ( 2 ). 
     
     
         2 . The device as set forth in  claim 1 , characterized in that the floor ( 3 ) is part of a container ( 1 ) for receiving the digestate or the digestate mixture ( 2 ). 
     
     
         3 . The device as set forth in  claim 2 , characterized in that the container ( 1 ) exhibits at least one outlet device ( 1   a ) for discharging a gaseous medium that is located in the container ( 1 ). 
     
     
         4 . The device as set forth in  claim 1 , characterized in that the inlet device ( 4 ) for introducing the gaseous medium is connected to a line ( 6 ). 
     
     
         5 . The device as set forth in  claim 1 , characterized in that the outlet device ( 1   a ) and the inlet device ( 4 ) are fluidly connected to each other via line ( 6 ) for recycling of the gaseous medium from the outlet device ( 1   a ) to the inlet device ( 4 ). 
     
     
         6 . The device as set forth in  claim 5 , characterized in that the line ( 6 ) is switched such that is can be fed alternatively or in addition to the gaseous medium coming from the outlet device ( 1   a ), with fresh air from the outside of the container ( 1 ). 
     
     
         7 . The method for operating a device for processing digestate or digestate mixtures ( 2 ), according to  claim 1 , wherein a digestate or a digestate mixture can be supplied into a closed container ( 1 ) and with a heated gaseous medium thereafter flowing through it, characterized in that the heat-up of the digestate or the digestate mixture ( 2 ) is carried out at least in part by heating the floor ( 3 ) of the container ( 1 ) using a heating element, whereby the heating element is different from the gaseous medium.
