ABSTRACT:
A method is described herein to disinfest, decontaminate and extend the shelf life of shellfish by using an open-end system where trawled shellfish are placed on a computer controlled conveyor belt after being washed with seawater. Shellfish are then transported into pressurized treatment tanks that contain either gas or gas molecules (i.e., 1-ascorbic acid). After exiting the tank the shellfish are automatically placed in rows on a conveyor belt for their controlled, sequential irradiation. The shellfish then enter the irradiation chamber in the presence of carbon dioxide and it is then irradiated with machine generated electron beams. Upon completion, the shellfish exit the irradiation chamber via a conveyor belt and are then transported to an agitated continuous flow depuration tank that is equipped with ultra-sonification devices. The shellfish remain in these tanks until arrival at the port.
