PLG Series Continual Plate Dryer
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
friendly 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; four sizes of 1200,
1500, 2200 and 3000; and three kinds of materials, namely A(carbon
steel), B(stainless steel used for those all parts 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 metres, now we have hundreds of models
of series products and various kinds of auxiliary devices available
to meet requirements of drying materials for customers.
Features:
(1) Easy control, wide application
1. Regulate thickness of materials, rotating speed of main shaft,
number of harrow’s arm, style of and sizes 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.
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 products 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.
Applications:
Drying, heat decomposition, combustion, cooling, reaction, and
sublimation
1. Organic chemicals
2. Mineral chemicals
3. Pharmaceutical and foodstuff
4. Feed and fertilizer
Features of technology:
1.Drying plate
(1). Designing pressure: general is 0.4MPa, Max. can reach 1.6 Mpa.
(2).Work pressure: general is less then 0.4Mpa, and Max. can reach
1.6 Mpa.
(3).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
(1).headstock revoluton:1~10 rpm, electromagnetism of transducer
timing.
(2).harrow arm: There are 2 to 8 pieces arm that be fixed on the
headstock 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
