10 Layers 1200mm Disc diameter Pharmaceutical Continuous Disc Plate Dryer
CPD Series Continuous disc dryer is a high efficiency conducting and continuous drying equipment. Its unique structure and operating principle determine that it has advantages of high heat efficiency, low energy consumption, small occupied area, simple configuration, easy operation and control as well as good operating environment and etc. It can be widely used in drying process in the fields of chemical, pharmaceuticals, agricultural, foodstuff, feed, and other industries.
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
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 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.
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.
