JYG Series New Type Hollow Paddle Dryer for Industrial Sludge
JYG Series Industrial Drying Equipment Hollow Paddle Dryer For
Industrial Sludge
DESCRIPTION
Dual counter-rotating shafts with unique intermeshing hollow
wedge-shaped paddles produce intimate mixing, optimize heat
transfer, and provide a self-cleaning feature. A large heat
transfer area to volume ratio is achieved by the use of hollow
paddles and a jacketed vessel, through which the heating medium
flows. The result is an efficient, compact machine with less space
requirements and lower installation cost.
FEATURES
1. The thermal efficiency reaches as high as 80%-90%. Heat
transfer coefficient K is 100-300Kcai/h.m2°C. Evaporation capacity
is 10-30Kcai/h.m2.
2. Operation method: support continuous operation and batch
operation, support vacuum drying for thermal sensitive material and
normal drying. Support heating, evaporating and cooling.
3. Heating resource: heat conducting oil, steam, water, hot air and
cooling fluid.
4. Special structure of oar blade with large heating area. The unit
volume is small.
5. Heating area is large in unit volume.
6. It is widely used for organic and inorganic substance, granule
material, sticky material and the material with high water content.
WORKING PRINCIPLE
JYG Series New Type Hollow Paddle Dryer for Industrial Sludge is a kind of conduction heating and low rotating speed-stirring
type drier. There is jacket on the body of drier, hollow oar blade
on the hollow shaft, filling heating medium in them, wet material
is stirred by oar blade and carries on heat exchange with shaft and
oar blade. The structure of machine is generally horizontal type
with two or four shafts.
HEAT SOURCES(Temperature at 180℃ - 250℃)
Heating by Steam
Steam enters the hollow shaft through a rotary joint and is evenly
distributed to all paddles. Condensate is removed with each
revolution.
Heating by Hot Oil(thermal fluid)
Hot oil(thermal fluid) enters and exits the hollow shaft through a
rotary joint. Pressure from the supply pump forces liquid through
the hollow paddles.
