Abstract
A system for irradiation of grain foods using one or more ultraviolet emitting sources is provided. The system includes an irradiation region in which the grain foods are irradiated by ultraviolet light. The system can include means for moving the grain foods through irradiation region, means for detecting the flow rate of the grain foods moving through irradiation region, and a control system for adjusting power provided to the ultraviolet emitting sources based on the flow rate of the grain foods.
Claims20
A system for irradiation of grain foods, the system comprising:
- an irradiation region for exposing grain foods to ultraviolet light;
- wherein the irradiation region includes a set of UV emitters positioned to irradiate the grain foods as the grain foods pass there through with UV radiation;
- means for moving the grain foods through the irradiation region;
- means for detecting a flow rate of the grain foods moving through the irradiation region;
- a control system for adjusting power provided to the set of UV emitters based on the flow rate of the grain foods moving through the irradiation region;
- and
- an analyzing module configured to analyze a grain optical reflectance under ultraviolet radiation.

- means for moving the grain foods through the irradiation region;
- means for detecting a flow rate of the grain foods moving through the irradiation region;
- an auxiliary light emitting source for testing grain fluorescence;
- a fluorescence sensor for detecting a fluorescent signal from the grain foods irradiated by the auxiliary light emitting source;
- and
- a control system for adjusting power provided to the set of UV emitters based on the flow rate of the grain foods moving through the irradiation system and an intensity of the fluorescent signal measured by the fluorescence sensor.
