(5) Although the drying materials are not flowing, by controlling the flowing of secondary steam, the drying materials can be regarded as flowing.
Hot fresh vapor enters the first drying room to heat the solid materials in it, meantime secondary steam discharged from the first drying room enters the second drying room to heat the solid materials there.
The drying materials are not flowing, after drying material of the i effect drying dried by the secondary steam of the i-1 effect drying room produced, it is regarded as i+1 effect drying.
