Pgc Continual Plate Dryer Drying Machine

DESCRIPTION

Powder Drying machine Continous Plate Dryer/ Disc Drying Machine

1.Have three types:normal pressure,closed,vacuum.

2.PGC series continual plate dryer is a kind of high effective conducting and continous drying machine.

PGC continuous plate dryer is a kind of high-efficiency continuous drying equipment. Its unique structure and working principle determine this drying machine has the characteristics, such as high thermal efficiency, low energy consumption, small space occupation and easy operation. PLG continuous plate dryer can be divided into normal pressure type, close type and vacuum type. Its drying areas range from 4 m2 to 180 m2. Equipped with corresponding auxiliary equipment, this drying machine can meet the drying requirements of various materials.

Working Principle
Wet materials are continuously fed into the first layer drying plate on the top of the dryer. They will be turned and stirred by the rakes whose arms make rotational motion. The materials flow through the surface of the drying plate along the index spiral line. On the small plate the materials will move to the outer edge and drop down to the large drying plate. On the big one they will move inward and drop to the small plate on the next layer from the central hole. Both small and large drying plates are arranged alternately so that the materials can get through the whole continuous plate dryer. The heating media will be led into the hollow drying plate. The heating media includes saturated steam, hot water and conduction oil, and it will enter from one end and derive from the other end. The dried materials will drop from the last layer of the drying plate to the bottom layer of the shell. Finally, they will be transferred to the discharge port by the rakes. The moisture escapes from materials and will be expelled from the wet discharge port on the top cover. The moisture of vacuum type drying machine will be drawn out by the vacuum pump. Drying pasty and heat sensitive materials, this continuous plate dryer can recover the solvent and conduct pyrolysis and reaction operation.

FEATURES
1. 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.
2. Easy control, wide application
(1) Regulate thickness of materials, rotating speed of main shaft,number of harrow 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.
3. 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.
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 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) 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,heat transfer oil. When the drying plates'temperature is 100ºC, hot water can be used ; when 100ºC~150ºC,it will be saturated water steam ≤0.4MPa or steam-gas, an when 150ºC~320ºC,it will be heat transfer oil; when >320ºC it will be heated by electric, oil or fused salt.
2.Material transmission system
(1) Main shaft revoluton: 1~10rpm, electromagnetism or stepless speed regulation by inverter.
(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
(1) Normal pressure:
(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.
