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