PG Series Continual Plate Dryer is a kind of high effective conducting and continuous drying
equipment. Its unique structure and operating principle determine that it has advantages of high heat
efficiency, low energy consumption, small occupying area, simple configuration, easy operating and
control as well as good operating environment etc.
It can be widely used in drying process in the fields of chemical industry. Pharmaceuticals, agricultural
chemicals, foodstuff, fodder, process of agricultural and sideline products etc. and is well received by
various sectors in their practical usage. Now there are three big categories, named normal pressure,
closed and vacuum styles; 1200, 2500, 2200 and 3000 size and so on; and three kinds of materials,
namely A(carbon steel ), B(stainless steel used for those all part where materials are contacted) and
C(on the basis of B to add stainless steel materials for vapor pipes, main shaft and support, and
stainless steel linings for cylinder body and top cover).
With a drying area being from 4 to 180 square maters, now we have hundreds of models of series
products and various kinds of auxiliary devices available to meet requirements of drying materials for
customers.
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.
Features of technology:
1. Drying plate
Designing pressure: general is 0.4MPa, Max can reach 1.6MPa.
Work pressure: general is less than 0.4 Mpa, and Max can reach 1.6Mpa.
Heating medium: steam, hot water, Oil. When the drying plates’ temperature is 100℃, hot water
can be used; when 100℃-150℃, it will be saturated water steam ≤0.4Mpa or steam-gas, and
when 150℃-320℃, it will be oil.
2. Material transmission system
Main shaft revolution: 1-10 rpm, electromagnetism or frequency steeples speed regulating.
Harrow arm: There are 2 to 8 pieces arm that be fixed on the main shaft on each layer.
Harrow’s blade: spliced on the harrow arms, float together with the surface of the plate to keep
contact. There’re several of types.
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
Normal pressure: Cylindrical shell or eight prismatic types, with whole body and split structure.
The main pipes of inlets and outlets of heating medium can be inside the shell, or outside the
shell.
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.
Vacuum: cylindrical shell could bear the exterior pressure of -0.098Mpa. The main ducts of inlet
and outlet is inside of the shell.
4. Air heater:
Normal used with the application of draft fan, in case the wet air enters, to increase drying
efficiency.
Features:
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.
