Abstract: A vertical cooker vessel is used for cooking a grain product. The cooker is vertically oriented and has a conical baffle so as to ensure plug flow so that grain is neither undercooked nor overcooked. The cooking water fills the vessel and maintained at a predetermined elevated temperature while a continuous stream of water is drawn off through a sieve in the bottom portion of the cooker, then recirculating the water, mixing with raw grain, and then heating, where steam is added to reheat the water and grain. The mixture is added to the top of the vessel. Cooked grain exits from the bottom of the cooker under control of a metering pump. Grain is separated from the water, with water from the separator returning to a mixer for mixing with the recycled water. A conical baffle is located near the sieve. This ensures plug flow of grain through the cooker. A lower second conical baffle prevents turbulent flow beneath the first conical baffle, which flow would otherwise disrupt plug flow.
