The disc dryer is intermittently stirredConductive dryerOn the basis of this, a series of advanced technologies have been integrated and continuously improved to develop a multi-layer fixed hollow heating circular loading tray, rotary rake stirring, vertical continuous drying equipment mainly based on heat conduction. This drying process involves passing a heat carrier into each hollow disk layer, indirectly heating the wet material placed on the disk surface through thermal conduction. Under the scraping action of the rotating rake blades, the moisture in the constantly moving and rolling material evaporates at the operating temperature, and its vapor is discharged with the equipment exhaust gas, thus continuously obtaining qualified dried products at the bottom of the equipment. In recent years, many countries have widely applied it in fields such as chemical engineering, dyes, pesticides, plastics, pharmaceuticals, and food, constantly improving and enhancing its use. Compared with traditional drying equipment, it has the advantages of high thermal efficiency, low energy consumption, uniform drying, good product quality, small footprint, fewer auxiliary equipment, less pollution, continuous production, convenient operation, and wide applicability. Therefore, there is a broad development prospect in drying technology, which has attracted more and more attention and research. Based on product performance, drying requirements, and processing capacity, the disc dryer adopts a series of measures such as spindle stepless speed regulation, manual adjustment of disc feeder height adjustment sleeve, control of temperature distribution of each layer of heating disc, and final cooling and temperature reduction, fully utilizingfinishDisc continuous dryerSuperior performance.

The wet material is continuously added to the first layer of drying disc on the upper part of the dryer by the feeder, and the rake arm with rake blades rotates to make the rake arm rotate and make the rake blades continuously flip the material. The material flows along an exponential spiral over the surface of the drying disc, and the material on the small drying disc is transferred to the outer edge, where it falls onto the outer edge of the large drying disc below. The material moves inward on the large drying disc and falls into the next layer of small drying disc from the middle discharge port. The drying plates of different sizes are arranged alternately up and down, allowing the material to flow continuously through the entire dryer. A hollow drying tray is filled with heating medium, which includes saturated steam, hot water, thermal oil, and high-temperature molten salt. The heating medium enters from one end of the drying tray and exits from the other end. The dried material falls from the last layer of the drying tray to the bottom of the shell, and is finally transferred by the rake blades to the discharge port for discharge. Moisture overflows from the material and is discharged through the dehumidification port located on the top cover. The moisture in the vacuum disc dryer is discharged through the vacuum pump port located on the top cover. Dry materials discharged from the bottom layer can be directly packaged. By adding fin heaters and solvent recovery condensers、Bag filter、Auxiliary equipment such as dry material mixing mechanism and induced draft fan can improve its drying production capacity. It can dry paste like and heat sensitive materials, conveniently recover solvents, and perform pyrolysis and reaction operations.

1. Continuous operation, high thermal efficiency. The disc continuous dryer uses conduction heat transfer for drying. During the drying process, only a very small amount (or no air) is introduced into the dryer, and the amount of exhaust gas carried is very small. Therefore, its thermal efficiency can reach over 65%.

2. Low power consumption and low noise. Due to the thin material layer and low spindle speed during the drying process, the material conveying system requires less power and consumes very little electricity. The power consumption of the entire drying device is only 1/5~1/7 of that of the convective heat transfer device, and the noise is very low.

3. The material is heated evenly and has a short drying time. Due to the material being transported along the drying tray during the drying processArchimedes spiralThe motion trajectory rolls forward, and the material travels 5 times the radius of the drying plate, falling layer by layer. Therefore, the time for the material to contact the heating plate is basically the same, and the heating is very uniform.

4. Small material loss and good environmental protection.

5. High drying capacity.

6. The equipment operates continuously in a closed environment, resulting in low labor intensity for workers.

7. The drying medium can be utilizedwaste heat boilerThe generated steam saves a significant amount of coal.

8. The product quality is stable.
