High Efficiency Continuous Disc Plate Dryer for Granulated sugar
1, Continuous plate dryer / disc dryer / CPD plate drying machine
2, Widely application in various industires.
3, Low energy consumption
4, Easy operation and control
CPD Continuous Disc Plate Dryer Descriptions
CPD series continuous plate dryer is a kind of high efficiency
conducting and continuous drying equipment. Its unique structure
and operating principle provide advantages of high heat efficiency,
low energy consumption, less occupying area, simple configuration,
easy operation and control as well as good operating environment
etc. Plate dryer is widely used in drying process in the fields of
chemical, pharmaceuticals, agricultural chemicals, foodstuff,
fodder, process of agricultural and by-products etc., and is well
received by various industries. Now there are three big categories,
normal pressure, closed and vacuum styles and four specifications
of 1200, 1500, 2200 and 2500; and three kinds of constructions A
(carbon steel), B(stainless steel for contact parts) and C (on the
basis of B to add stainless steel for steam pipes, main shaft and
support, and stainless steel linings for cylinder body and top
cover). With a drying area of 4 to 180 square meters, now we have
hundreds of models of series products and various kinds of
auxiliary devices available to meet requirements of various
products.
CPD Continuous Disc Plate Dryer Working Principle
The wet material is fed continuously to the first drying layer on
the top of the dryer. It will be turned and stirred by rakes when
the rake arm rotates and drop down to the outer edge of the large
drying plate along the exponential helical line. The material will
be moved from the small drying plate to its outer edge and drop
down to the outer edge of the large drying plate underneath. Both
small and large drying plates are arranged alternately so the
materials can go through the dryer continuously. The heat medium
can be saturated steam, hot water or thermal oil. The heat will be
led into hollow drying plates from one end and come out from the
other end. The dried materials will drop from the last layer of the
drying plate to the bottom of the dryer and then moved by rakes to
the discharge outlet. The material moisture will be removed from
the exhaust outlet on the top cover. For the vacuum-type plate
dryer, the moisture will be sucked out by the vacuum pump on the
top cover. The dried materials will be discharged from the bottom
layer. The drying capability can be improved if the dryer equipped
with supplementary devices such as finned heater, condenser for
solvent retrieval, bag dust remover, return and mix mechanism,
draft fan, and etc.
CPD Continuous Disc Plate Dryer Feature
1. Easy control, wide application
2. Easy and simple operation
3. Low energy consumption
4. Good operation environment, solvent can be recovered and powder discharge meet the requirements of exhaust.
5. Easy installation and small occupying area.
CPD Continuous Disc Plate Dryer Features Of Technology
1.Drying plate
(1) Desiging pressure: general is 0.4MPa, Max. can reach 1.6MPa.
(2) Work pressure: general is less than 0.4MPa, and max. can reach
1.6MPa.
(3) Heating medium:steam, hot water, oil. When the drying plates’
temperature is 100°C, hot water can be used ; when 100°C~150°C,it
will be saturated water steam ≤0.4MPa or steam-gas, and when
150°C~320°C,it will be oil; when >32 C it will be heated by
electric, oil or fused salt.
2.Material transmission system
(1) Main shaft revoluton: 1~10r/min, electromagnetism of transducer
timing.
(2) Harrow arm: There are 2 to 8 pieces arm that be fixed on the
main shaft on the every layers.
(3) Harrow's blade: Surrounding the harrow's blade, float together
with the surface of the plate to keep contact. There're various of
types.
(4) Roller: for the products easily agglomerate, or with the
requirements of grinding, the heat transfer and drying process
might be
reinforced by placing roller(s) at the appropriate place(s).
3.Shell
There're three types for option: normal pressure, sealed and vacuum
(1) Normal pressure:Cylinder or eight-sided cylinder, there are
whole and dimidiate structures. The main pipes of inlet and outlet
for heating media can be in the shell, also can be in the outer
shell.
(2) Sealed: Cylindrical shell, could bear the interior pressure of
5kPa, the main ducts of the inlet and outlet of heating media might
be inside of the shell or outside.
(3) Vacuum: Cylindrical shell, could bear the exterior pressure of
0.1MPa. The main ducts of inlet and outlet is inside of the shell.
4.Air heater
Normal for the application of big evaporation capacity to increase drying efficiency.
CPD Continuous Disc Plate Dryer Application
Drying, heat decomposition, combustion, cooling, reaction, and
sublimation:
1. Organic chemicals
2. Mineral chemicals
3. Pharmaceutical and foodstuff
4. Feed and fertilizer
