The advantages of forcedcirculation and indirect heating are lowered steam costs through return of condensate to boilers, lower liquor volumes, and greater uniformity of cooking.
强制循环和直接加热的方式的优点是通过回用冷水使耗汽量，耗水量降低、并使蒸煮更加均匀。

Generally forced convection circulationheating device taking gas as heat transmission medium requires high temperature uniformity. So it is very important for selection of fans and control method.
