HVRD Series Horizontal Vacuum Rake Dryer For Paraformaldehyde Drying
vacuum rake dryer is a new type drying machine ,which is designed
with the combination of oar blade dryer heat drying principle, with
a higher drying efficiency, for a variety of raw materials.
The inner equipped oar blade and screw with continuous ,axial and
radial mixing of raw materials ,make the materials to be dried more
evenly.With applied both oar blade and screw, when the raw
materials were turned over by mixing blades, they speed up the
materials contact with heating surface of the dryer,so heat
transfer rate is increased,and is conducive to moisture
evaporation.
Product Structure
2.1 The loading cylinder of raw materials will be equipped with
heating jacket,and heat insulation layer will be equipped outside
the jacket,which will prevent the heat be transferred ,and also
reduce the heat loss. Discharge hole is equipped with the lower
part of the cylinder, on the top of the cylinder with two feeding
holes and an air exhaust outlet.When feeding,the raw materials
should be fed equally from the two feeding holes,the best feeding
capacity is about 60%-80% of the volume of the cylinder,the max
feeding capacity should not exceed 80%,otherwise will affect the
smooth discharge of gas evaporation .When the sticky raw material
is feeding,the feeding capacity should be reduced, to prevent the
drive motor overloaded, damage to equipment.
2.2 Hollow shaft is set inside the center of of the cylinder,in
heating medium will be put into the shaft( like hot conduction oil
or hot water).
2.3 On the hollow shaft distributed with oar blades with certain
angle,the oar blades are also hollow within heating
transferred,inlet and outlet of hot oil conduction are equipped
inside of the blades,to ensure the heat transfer efficiency during
the drying
2.4 Seals: Packing seals are equipped during shaft and cylinder.
2.5 Transmission:Except the special models,we normally apply the
chain or gear transmission style.Pivot bear apply duplex bearing
combination ,with tapered roller bearing and deep groove ball
bearing combined,to meeting the requirements of radial and axial
force.
Product Structure Features
3.1 Compact structure,small occupied area.
3.2 High utilization of heat,low operation cost.
3.3 Wide adaptability of raw material,the drying degree is evenly.
3.4 Suitable for drying many kinds of raw meterials.
Product Application
-- The following materials are dried in pharmaceutical, food, chemical and other industries:
-- Suitable for paste, paste and powder materials.
-- Heat-sensitive materials requiring low temperature drying.
- -Easy to oxidize, explosive, strong stimulation, highly toxic materials.
- -Materials requiring recovery of organic solvents.
Product Working Principle
HVRD Vacuum Harrow Dryer is an innovation horizontal batch-type
vacuum dryer improved on the basic of introduced technology of
harrow dryer.
The moister of wet material will be evaporated by heat
transmission. The stirrer with blade will remove material on hot
surface and move in the container to form cycle flow .The
evaporated moisture will be pumped by vacuum pump.
