16 Layers Chemical Multilayer Disc Drying Machine
On the basis of intermittent stirring dryer, a disc plate dryer is a kind of multi-layer fixed hollow heating circular carrier disc developed by continuous improvement, which is developed by continuous improvement. The drying process is to pass the heat carrier into each layer of hollow disc. In the way of heat conduction, the wet material placed on the surface of the disk is heated indirectly, and the wet portion of the rolling material is evaporated under the operating temperature under the action of rotating the rake and rake, and the steam is discharged with the tail gas of the equipment, so that the qualified dry finished products are continuously obtained at the bottom of the equipment.
Compared with the traditional drying equipment, it has the advantages of high thermal efficiency, low energy consumption, uniform drying, good product quality, small occupation, less auxiliary equipment, less pollution, continuous production, convenient operation and wide range of application. Therefore, there is a broad prospect in drying technology, which has attracted more and more attention and research.
According to the product performance, drying requirements and processing capacity, the disc dryer adopts a series of measures, such as adjusting the speed of spindle step-less, manually adjusting the height of the disc feeder, controlling the temperature distribution of each layer of the heating disk, and cooling at the end of the period, etc. Give full play to the disc continuous dryer's superior performance.
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.
