DESCRIPTION
◆ Applicable for drying or cooling of paste, particle, powder and slurry state
of material, perform the process of drying, cooling, heating, sterilizing, react-
ing and combustion under low temperature. The special stirring and heating
transferring blade, makes high heat transferring efficiency, and provide self-
cleaning function. The special chock shaped stirring and heat transferring
blade has high heating efficiency and self-cleaning function of the heating
transferring surface.
◆ Hollow chock shaped blades are concentrated on the hollow shaft. Heat
media flow through the blade from the hollow shaft. The heat transferring
area in the effective volume is very high. The temperature range of heating
media is from -40˚C to 320˚C. It might be steam, or liquid state, such as
steam, thermal oil etc. Indirect heating, there’s no heat carried out by air.
All heat is utilized for to drying the material except the lost of heat insula-
tion layers. The surface of chock shaped blade has self-cleaning function.
The relative movements of the product particles and the chocked shaped
surface might clean the material attached to the chock shaped surface, so to
keep the cleanliness of heat transferring surface during working.The shell of
hollow blade dryer is Ω shape. 2 or 4 pieces of hollow stirring shaft are usu-
ally equipped in the shell. To avoid any leakage of material, there’re sealed
terminal cover and top cover with the shell. The heat transferring media flow
through the rotation connector, jacket’s shell and hollow stirring shaft. To en-
sure best transferring effect, the hollow stirring shaft adopts different interior
structure in accordance with different heating media.
FEATURES
◆ The heat consumption of blade is low: No heat carried out by the air be-
cause of indirect heating; there’s no heat insulation layer with the exterior wall
of the dryer. It consumes 1.2 kg of steam to evaporate 1kg of water for to dry-
ing slurry state of material.
◆ The cost of the blade dryer is low: The unit effective volume has very
large heat transferring surface, so the processing time is shorted, the size of
the equipment becomes small. The building area and place are sharply de-
creased.
◆ The range of material to be processed is wide: Heat sensitive material and
the materials to be processed under high temperature might be processed
with different heating media. The normal media are: steam, thermal oil, hot
water and chill water. It might be continuous or batch operation, widely used in
many areas.
◆ The pollution is less: Without any carrying air, so little powder is carried out.
The solvent evaporated is very few, it easy to be processed. For the material
that might cause pollution or the solvent to be recovered, it might adopt sealed
circulation.
◆ The operation cost is low: 1hour/day. Operator is enough for normal opera-
tion. Low stirring speed and reasonable structure, the worn amount is few, and
the maintenance fee is low.
◆ Steady operation: The material particles fully contact heat transferring sur-
face, because of the special compressing and swell-stirring effect of the chock
shaped blade. The difference of the temperature, humidity and mixing effect
are very small in the different axial area, so to ensure the stability of process.
