Abstract
Abstract The disclosure is directed to an irradiator for fluent materials wherein the same traverse a single flow path through the irradiator which flow path is repeatedly reversed. The reversing flow path is defined, in part, by a plurality of passages which are concentric with a source of radiation. Curved end walls are provided at opposite ends of each passage to repeatedly direct the flow path along different ones of the concentric passages past the source of radiation at varying radial distances therefrom and in substantially surrounding relation thereto. Conveyor means in the form of screw conveyors are embedded in each passage wall for the intermittent or continuous removal of sediment derived from the fluent material traversing the flow path.

Claim 6
Dependent Claim
73 words
A fluent material irradiator, comprising; a source of radiation, fluent material passage means adjacent said source defining a first path of material movement past said source, means for separating sedimentary material from the fluent material, and conveyor means intercommunicating said passage means and an external area thereof and defining a second different path of material movement past said source for removing sedimentary material from said passage means and for irradiating said sedimentary material.
Claim 7
Dependent Claim
73 words
A fluent material irradiator, comprising; a source of radiation, fluent material passage means adjacent said source defining a first path of material movement past said source, means for separating sedimentary material from the fluent material, and conveyor means intercommunicating said passage means and an external area thereof and defining a second different path of material movement past said source for removing sedimentary material from said passage means and for irradiating said sedimentary material.
Claim 8
Independent Claim
63 words
A method of simultaneously irradiating flowable and sedimentary material comprising; flowing said flowable material past a source of radiation and concurrently separating sedimentary material therefrom into a flowable material rich portion and a sedimentary material rich portion, separately mechanically conveying said sedimentary material rich portion past said source, and limiting the rate of sediment conveyance to not exceed the flowable material flow rate.
Claim 9
Independent Claim
63 words
A method of simultaneously irradiating flowable and sedimentary material comprising; flowing said flowable material past a source of radiation and concurrently separating sedimentary material therefrom into a flowable material rich portion and a sedimentary material rich portion, separately mechanically conveying said sedimentary material rich portion past said source, and limiting the rate of sediment conveyance to not exceed the flowable material flow rate.
