Abstract: A continuous flow pressurized cooker/blancher cooks a food product by continuously transporting the product on a conveyor system and by forcing steam through or over the surface of the food product. The food product to be cooked may be, but is not limited to, seafood and preferably crustaceans. The cooker/blancher includes an exterior pressurized housing, an infeed weigh hopper, an infeed and an outfeed transfer device, and an internal conveyor system. Each transfer device comprises an internal and an external transfer chamber. A pressure assembly forces steam into the exterior pressurized housing while the transfer device is adapted to maintain a selected pressurized environment.
