DW Mesh belt Drying Oven (Mesh belt dryer ) (Conveyor oven )( Mesh
belt drying machine )
Preface
This machine is a continuous penetrating flow drying equipment
applied for drying pieces strip and particles state materials with
good ventilation. The machine is suitable for the materials such as
dewatering vegetable, herbal medicine of traditional Chinese
medicine and others, for which the water contents are high and high
drying temperature is not allowed. The machine owns the advantages,
of fast drying speed, high evaporation capacity and good product
quality. The de-watered & filtered cake state paste material should
be made into particles or strips before drying process.
Principle
The materials are uniformly distributed on the mesh-belt by the
material feeder. The mesh-belt generally adopts 12-60 mesh
stainless steel mesh and it is drawn by a transmission device and
move inside the dryer. The dryer is composed of several sections.
For each section the hot air is circulated separately. Part of
exhausted gas is exhausted by a special moisture exhaust blower.
The waste gas is controlled by an adjustment valve. The hot air
passes through the mesh-belt covered with bring water material
away. The mesh-belt moves slowly, running speed can be freely
adjusted according to the material property. The final products
after the drying process will fall into the material collector
continuously. The top and low circulation units can be freely
equipped according to client requirement;

Technical advantages of DW series conveyor mesh belt dryer:
1) Wide applications: Multi belt dryer is specially designed for
drying those wet material which need long residence time. The
residence time of this DW multi belt dryer is adjustable from 60
minutes to 120minutesbased on the required drying technique.
2) Energy-saving: The five-layer drying belts are completely
installed inside a well insulated drying chamber which can
considerably reduce heat loss. The hot air is blown into the belt
dryer from the bottom and then penetrates through each layer of wet
material which can enhance heat transfer and reduce heat loss in
exhaust gas.
3) Uniform drying: The drying chamber has five drying zones and the
specially designed air distributor can make sure uniform air flow
in each drying zone to guarantee uniform drying.
4) Easy operation and maintenance: The whole drying system is
highly automatic. The simple but practical design (The dryer only
use one blower and exhaust fan) can not only reduce production cost
but also the maintenance and repair cost.
