A multipurpose irradiation plant for simultaneous treatment of different foods

An industrial multipurpose irradiation plantwith a particularly high effectiveness of radiation utilization is presented. The originality of this conceptual design consists of the simultaneous treatment of two products, which are separately irradiated to either high or low absorbed doses. A pneumatical transport system into appropriate channels with air mixing during irradiation has been proposed for the radappertization of granular animal feed, meanwhile a conventional truck-conveyor system has been suggested for the sprout inhibition treatment of potatoes. Moreover, potatoes pass through the irradiation cell twice at high and low level respectively.
