Irradiation device for continuous irradiation

The device is designed for continuous irradiation of powders, granular materials, suspensions, emulsions, and syrupy and other liquids. Typical materials are peat, starch, gelatin, etc. The irradiation proceeds in a container consisting of an upper cylindrical part, fitted with a filling tube or opening, and a lower conical part, fitted with a discharge tube or opening. The radiation source (system of radiation sources) is accommodated in a concentric vertical tube inside the container. While being irradiated, the material is stirred by means of a stirring equipment. Conveniently, this stirring equipment can be a planetary system revolving about the container axis, each partial stirrer revolving about its own axis. The radiaton source usually contains 60Co or 137Cs. The container consist of an outer supporting jacket and a protective inner wall, made, e.g., of aluminium, which can be reinforced. (P.A.). 2 figs
