Description
Technical field
The present invention relates to a kind of drying equipments, and in particular to the dry drying system of granular material.
Background technique
Dryer has belt drying, roller drying, box drying, the several modes such as tower drying；Heat source has coal, electricity, gas
Deng；Material has hot-air flow formula and radiant type etc. during the drying process, and hot wind roller drying is that thermal current travels forward from tail portion,
It comes into full contact with material, is made full use of by heat transfer, convection current, radiant heat transfer amount；Thermal energy is directly passed to material, makes material
Moisture be constantly evaporated in cylinder.
In traditional dryer, material goes out from the feed inlet feed inlet and outlet of dryer completes drying, if drying for the first time
Degree be unsatisfactory for requiring, then need material carrying out secondary drying, even if the drying temperature of secondary drying is lower than for the first time,
Secondary energy consumption consumes energy lower than for the first time, but the total energy consumption dried twice is high, and consuming time is long, needs in material transfer process
Take considerable time especially inventory it is more in the case where, and material is in transfer process, once contact moisture-sensitive with air.
Summary of the invention
