Energy-efficient NLG2.0 Inner Heating Fluid Bed Drying
Machine, NLG2.0 Fluid Bed Drying Machine
Inner heater fluid bed dryer is developed based on normal fluid bed
dryer and indirect heated dryer.
Immerse the heat exchanger in the material that is fluidized and
dried. The heat required for dewatering is provide by tube heat
exchanger and fluidizing hot air.
The air velocity required foe to dry the material is less. The main
heat is provided by the heat exchanger inside, the hot air is
mainly for fluidization of material, so the hot air velocity
required is much less compare to normal fluid bed dryer, power
consumption and heat lost with the tail gas are sharply reduced.

5. Heat sensitive materials can be used for drying with low
temperature and the particles will not be damaged.
6. This kind of drying machine is suitable for granular materials,
powdery materials, bulk materials, fibrous materials and even
special shape materials.
Speciality Details of Fluidized Bed Drying Machine:
The fluidized bed drying equipment has the following specific
characteristics. The drying equipment is suitable for the drying of
the uncondensed granular materials. The diameter of the particles
can be from 30um - 6um.The structure of the drying equipment is
simple and the production capacity is large, ranging from tens to
400,000 kilograms per hour. Thermal efficiency is about 70%, to
remove the material of the combined water, the thermal efficiency
is about 30% - 30%, material residence time in the fluidized bed is
associated with the structure of the fluidized bed, such as
reasonable design, the residence time in the materials in the
fluidized bed can any longer.
The disadvantage is that hot air has a large resistance through the
distribution board and material layer, generally about
490-1470pa.The energy of the blower is high.
For monolayer fluidized bed drying equipment materials in the
fluidized bed is in a state of completely mixed, part of the
material from loading port to the discharge port, may go short
circuit and fly directly toward the exit, causing uneven material
drying. In order to improve the uniformity of the material in
fluidized bed, the fluidized bed of different structures is
generally adopted. The single - layer fluidized bed, horizontal
multi-chamber fluidized bed, multi-layer fluidized bed, etc.
