La description
Descriptions PLG 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; ***0, ***0, ***0 and
***0 sizes and so on; and three kinds of materials, namely A(carbon
steel), B(stainless steel used for those all parts where materials
are contacted) and Clon 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 **0 square meters, now we have hundreds of models
of series products and various kinds of auxiliary devices available
to meet requirements of drying materials for customers.
 Applications Drying, heat decomposition, combustion, cooling
reaction, and sublimation
1.Organic chemicals
2.Mineral chemicals
3.Pharmaceutical and foodstuff
4.Feed and fertilizer Features (1) Easy control, wide
application
1.Regulate thickness of materials, rotating speed of main shaft,
number of harrow's arm, style and sizes of harrows achieve best
drying process.
2.Each layer of drying plate can be fed with hot or cold media
individually to heat or cold materials and make temperature control
accurate and easy.
3.Dwell time of materials can be accurately adjusted.
Â
4.Single flowing direction of materials without return flowing and
mixing, uniform drying and stable quality, no re-mixing is
required.
(2) Easy and simple operation
1.Start stop of dryer is quite simple
2.After material feeding is stopped, they can be easily discharged
out of the dryer by harrows.
3.Careful cleaning and observation can be carried inside the
equipment through large-scale viewing window.
(3) Low energy consumption
1.Thin layer of materials, low speed of main shaft, small power and
energy required for conveying system of materials.
2.Dry by conducting heat so it has high heating efficiency and low
energy consumption.
(4) Good operation environment, solvent can be recovered and powder
discharge meet the requirements of exhaust.
1.Normal pressure type: as low speed of air flow inside the
equipment and moisture being high in upper part and low in lower
part, dust powder couldn't float to the equipment, so there is
almost no dust powder in tail gas discharged from the moist
discharge port on the top.
2.Closed type: equipped with solvent recovery device that can
recover organic solvent easily from moist-carrier gas. The solvent
recovery device has simple structure and high recovery rate, and
nitrogen can be used as moist-carrier gas in closed circulation for
those subject to burning, explosion and oxidation, and poisonous
materials in order for safe operation. Especially suitable for
drying of flammable, explosive and poisonous materials.
3.Vacuum type: if the plate dryer is operating under vacuum state,
it is particularly suitable for drying heat sensitive
materials.
(5) Easy installation and small occupying area.
1.As the dryer is in a whole for delivery, it is quite easy to
install and fix at site only by hoisting.
2.As drying plates being arranged by layers and installed
vertically, it takes a small occupying area though drying area is
large. Features of technology 1.Drying plate
(1). Designing 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 platess
temperature is **0℃, hot water can be used; when **0℃~**0℃,
it will be saturated water system ≤ 0.4Mpa or steam-gas, and when
**0℃~**0℃, it will be oil.
2.Material transmission system
(1).Main shaft revoluton:1~*0 rpm, electromagnetism or frequency
stepless speed regulating.
(2).harrow arm: There are 2 to 8 pieces arm that be fixed on the
main shaft on each layer.
(3). Harrow's blade: Spliced on the harrow arms, float together
with the surface of the plate to keep contact. There're various of
types.
Â
(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: Cylindrical shell or eight prismatic type,
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.
(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: The Cylindrical main ducts shell, of inlet could and
outlet bear is the inside exterior of the pressure of 0.**6MPa.
4. Air heater: the application of draft fan, incase the wet air
enters, to Normal used with increase drying efficiency.
 Principle Wet materials are fed continuously to the first
drying layer on the top of the dryer. They will be turned and
stirred by harrow arms when the arm rotates and drop down to the
outer edge of the large drying plate along the exponential helical
line. On the small drying plate -they will be moved to its outer
edge and drop down to the outer edge of the large drying plate
underneath and will be moved inward and drop down from its central
hole to the small drying plate on the next layer. Both small and
large drying plates are arranged alternately so as materials can go
through the whole dryer continuously. The heating media, which
could be informs of saturated steam, hot water or heat conducting
oil will be led into hollow drying plates from one end to the other
end of the dryer. The dried materials will drop from the last layer
of the drying plate to the bottom layer of the shell body and will
be moved by rakes to the discharge port. The moisture escapes from
materials and will be removed from the moist discharge port on the
top cover or sucked out by the vacuum pump on the top cover for
vacuum-type plate dryer. The dried materials discharged from the
bottom layer can be packed directly. The drying capability can be
raised up if equipped with supplementary devices such as finned
heater, condenser for solvent retrieval, bag dust remover, return
and mix mechanism for dried materials and drawing fan etc. Solvent
in those dried paste and heat sensitive materials can be easily
retrieved, and thermal decomposition and reaction can be also
carried out.
