A process for manufacturing dehydrated precooked flaked pinto beans begins with cleaning a quantity of beans. The cleaned beans are then pressure cooked. Following cooking, the beans are deposited on a perforated conveyor for transportation through a first dehydrator which reduces the moisture content of the beans to about 20%. The cooked dehydrated pinto beans are then directed through a roller mill to convert the beans into flakes. Alternative to being dehydrated in a first dehydrator before being converted into flakes, the beans may be separated on a water separating conveyor and not undergo any dehydration. The cooked dehydrated bean flakes are then transported through a dehydrator which reduces the moisture content thereof to less than about 10%.
