An apparatus for sterilizing flowable food products, comprising an elongated cell including a radiation-emitting elongated member, end cell bodies supporting the ends of said member, a first quartz tube spacedly surrounding said member, said first quartz tube being transparent to said radiation, a second tube spacedly surrounding said first tube and defining a circulation space with said first tube, said second tube being opaque and reflective to said radiation, said first and second tubes being supported by said end cell bodies in fluid-tight engagement therewith, said end cells bodies each defining a first chamber in communication with said space and having a port for a flowable food product circulating through said space and a second chamber isolated from said circulation space, openable from the outside of said cell and providing an access into said first quartz tube to extract said radiation-emitting elongated member without disturbing the flow of food products through said cell.
