Product Introduction / INTRODUCE

A Disc Continuous Dryer is a conduction-type continuous drying equipment. Its structure and working principle determine its high thermal efficiency, low energy consumption, small land occupation, simple configuration, easy operation and control, and good operating environment, making it widely applicable to drying operations in industries such as chemicals, food, feed, and agricultural and sideline products processing.

Product Specifications / Parameter

PRINCIPLE OF OPERATION

Moist material is continuously added to the top layer of the dryer's first drying tray from the feeder. The scraper arm with rake blades performs a circular motion, continuously flipping the material. The material flows over the surface of the drying tray along an exponential spiral line; the material on the small drying tray is moved to the outer edge and falls into the outer edge of the larger drying tray below. The material on the larger tray moves inward and falls through the center discharge opening into the next layer of smaller trays. The trays of different sizes are alternately arranged vertically, allowing the material to continuously pass through the entire dryer. A heating medium, such as saturated steam, hot water, or thermal oil, is introduced into the hollow drying trays, entering at one end and exiting at the other. The dried material falls from the upper tray to the bottom of the shell and is then conveyed by the rake blades to the discharge opening. Moisture is released from the material and排出 through a moisture exhaust port located on the top cover; the moisture from the vacuum disk dryer is discharged through a vacuum pump port on the top cover. The dried material discharged from the bottom can be directly packaged. By adding auxiliary equipment such as finned heaters, solvent recovery condensers, bag filters, dry material blending mechanisms, induced draft fans, etc., the drying capacity can be increased, allowing for the drying of paste-like and heat-sensitive materials, convenient recovery of solvents, and the ability to perform thermal decomposition and reaction operations.

Product Features/ Characteristics

(1) Easy to regulate; versatile

Adjust the thickness of the material layer, spindle speed, number of rakes, and type and size of the rake blades to achieve an ideal drying process.

Each layer of the drying tray can be individually heated or cooled using hot or cold medium, providing accurate and easy temperature control of the material.

The material's dwell time is adjustable.

The material flows in a single direction without any mixing back, it is dry and uniform, with stable quality and does not require further mixing.

(2) User-friendly and easy to operate

● The operation of starting and stopping the dryer is extremely simple.

After stopping the material supply, the conveying material scraper blades can quickly empty the material from the dryer.

● Through the viewports of the specific inspection door, a thorough cleaning and observation of the equipment interior can be conducted.

(3) Low energy consumption

● Thin material layers, low main shaft speed, and a small power requirement for the material conveying system, resulting in low energy consumption.

● Drying by conducting heat, high thermal efficiency, low energy consumption.

(4) Excellent operating environment, recyclable solvents, and dust emissions meet requirements.

● Atmospheric Pressure Type: Due to the low air flow velocity inside the equipment and the humidity distribution being higher at the top and lower at the bottom, dust is difficult to rise to the top of the equipment. Therefore, the exhaust gas emitted from the moisture exhaust outlet at the top contains almost no dust.

● Sealed Type: Equipped with a solvent recovery unit, which allows for easy recovery of organic solvents from wet gases. The solvent recovery unit is simple and boasts a high recovery rate. For flammable, explosive, toxic, and easily oxidizable materials, nitrogen can be used as the wetting gas for closed-loop circulation, ensuring stable operation. Particularly suitable for drying flammable, explosive, and toxic materials.

● Vacuum Type: A disk dryer operated under vacuum, particularly suitable for drying heat-sensitive materials.

(5) Easy installation, minimal land area required

The dehydrator is factory-assembled and shipped as a whole unit, requiring only hoisting into place for easy installation and alignment.

● Due to the dry disk layer arrangement and vertical installation, even with a large drying area, the footprint is small.
