Product Details

　　Disc type continuous dryerWorking Principle:

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 auxiliary equipment such as fin heaters, solvent recovery condensers, bag filters, dry material mixing mechanisms, and induced draft fans, the production capacity of drying can be improved. Drying paste like and heat sensitive materials can facilitate solvent recovery and enable pyrolysis and reaction operations.

1、 Characteristics and economy of disc dryer:

1. Continuous operation, high thermal efficiency.

2. Low power consumption and low noise.

3. The material is heated evenly and has a short drying time.

4. Small material loss and good environmental protection.

5. High drying ability.

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

7. The drying medium can utilize the steam generated by the waste heat boiler, thereby saving a large amount of coal.

8. The product quality is stable.

　　2、 Application scope:

1. Organic chemical products include polyvinyl chloride resin, polytetrafluoroethylene resin, fumaric acid, anthraquinone, nitroanthraquinone, melamine, cyanuric acid, p-aminobenzenesulfonic acid, antioxidant 168, phenol As, stearate, nitroaniline, calcium formate, triethylenediamine EDTA、 Rubber accelerators, sodium benzenesulfonate, isophthalic acid, sodium dimethyl pentasulfonate, thiourea, oil soluble aniline black dye, acid black dye, indigo and other organic chemical raw materials and intermediates.

2. Inorganic chemical products include light calcium carbonate, active calcium carbonate, nanoscale ultrafine calcium carbonate, magnesium carbonate, sulfur concentrate, pyrite, copper nickel ore, white ash black, strontium carbonate, barium carbonate, potassium carbonate, lithopone, insurance powder, silicon micro powder, potassium sulfate, microsphere catalyst, copper sulfate, nickel sulfate, nickel nitrate, sodium molybdate, sodium chloride, cryolite, iron oxide red, nickel oxalate, cobalt oxalate, iron oxide black, lithium hydroxide, nickel hydroxide, sulfur, etc.

3. Pharmaceutical, food, tea, flower extracts, ginkgo leaves, chocolate powder, starch, corn germ and other raw materials and pharmaceutical intermediates.

4. Feed, fertilizer potassium carbonate, bio potassium fertilizer, protein feed, feed mycelium, bran, distiller's grains, grain seeds, herbicide cellulose, etc.

　　3、 Operation process:

1. Basic configuration of disc dryer process: Wet material is evenly added to the top of the disc continuous dryer through a quantitative feeder, and the drying process is completed when it flows through the dryer. Dry material is discharged from the bottom of the dryer.

2. Process of adding a heat exchanger to a disc dryer: suitable for drying processes with high evaporation intensity. On the basis of the basic configuration, a fin heater is added to introduce a small flow of hot air into the dryer, which is used to absorb the water vapor escaping from the material during the drying process and prevent moisture from condensing at the top of the dryer and exhaust pipe.

3. Process of adding hot air system to disc dryer: suitable for drying processes with high evaporation intensity. On the basis of the basic configuration, equipped with fin heaters and exhaust induced draft fans, the moisture released during the drying process is quickly carried away by the incoming hot air, further enhancing heat transfer and drying process, and preventing moisture condensation in the exhaust pipe at the top of the dryer.

4. Process of adding dust removal device to disc dryer: Suitable for drying toxic, harmful materials that can cause environmental pollution and easily floating materials such as pesticides, dyes and their intermediates. On the basis of basic configuration, equipped with bag filter fin heater and induced draft fan to capture trace, particularly fine and light materials carried in the exhaust gas, in order to protect the environment and reduce product loss.

The new type of vibrating disc dryer is a new type of high-efficiency and energy-saving disc dryer that fully utilizes the principles of vibration and conduction heat transfer, integrating radiation and conduction into one. The heat and mass transfer rate is increased by 30% compared to ordinary disc dryers. The advantage of being suitable for drying powder materials is that the vibration does not damage the materials. Especially suitable for drying materials that require the preservation of intact particle size. The vibrating disc dryer has the characteristics of high thermal efficiency, low energy consumption, good product quality, small footprint, simple configuration, easy operation and control, and good operating environment. It is widely used for drying ultrafine powder materials in industries such as chemical, pharmaceutical, pesticide, food, feed, and agricultural products processing.
