Procédé et dispositif d'inactivation d'une masse microbiologique contaminée et comprenant des particules de matière solide à l'aide d'électrons accélérés
The method comprises premixing the mass containing solid particles with a gelling agent and a liquid, transporting the premixed mass through a molding unit, in which the mass is formed in an area to a layered volume with a layer thickness of 1-3 mm, and impinging the mass in the layered volume area from two sides with accelerated electrons by using electron beam generators (17, 18) that are arranged opposite to each other. The solid particles are crushed to a particle size of 0.2-0.6 mm before adding the gelling agent. The mass is pumped, sucked or pressed by the molding unit.

The solid particles are crushed to a particle size of 0.2-0.6 mm before adding the gelling agent. The mass is pumped, sucked or pressed by the molding unit. The output parameter of the electron beam generator is adjusted, so that the electron energy applied on the mass has a maximum in the average layer thickness of the volume. The mass is drawn from the liquid after impinging with the accelerated electrons. An independent claim is included for a device for inactivating a microbiologically contaminated mass containing solid particles using accelerated electrons.
