There are three major types: normal pressure type, closed type, and vacuum type; and four major models: 1200, 1500, 2200, 2500 and 3000; and three kind of material grades, A (carbon steel), B (use stainless steel for material contacted area), and C (use stainless steel for material contacted area, steam pipes, main shaft and supports, and linings for cylinder body and top cover).The drying area of the dryer is 4 to 180. We have produced hundreds of models with auxiliary devices which are available to meet requirements of all customers.
CPD Continuous Disc Plate Dryer Working Principle
The wet material is fed continuously from a feeder onto the top plate of the dryer. The rotating transport arms with plows transport the material in a spiral pattern across the heated surface of the plate. By this means, the product is repeatedly turned over and comes frequently into contact with the drying surface. The material is conveyed towards the outer rim on the small diameter plates, where it fall over the edge onto the large plate directly below. On this plate the material is moved inwardly toward the central opening through which the material falls onto the next small plate By means of this plate arrangement, the material is conveyed continuously through the drier. The dried material falls from the last plate onto the bottom surface of the drying chamber where it is conveyed by means of plows to the discharge duct. The moisture is evaporated from the material during transport through the drier, At the same time, the hot air after being filtered and heated is blown into the drying chamber. The temperature of the hot air is similar to the plates temperature and its main function is to convey the moisture from the material. The wet gas will be exhausted into the air after being filtered.
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
