With the continuous improvement of industrial production technology, higher technical requirements have been put forward for drying equipment, and energy-saving and environmentally friendly disc drying equipment is increasingly favored by production enterprises. The ZPLG series vacuum disc dryer is widely used in drying operations in industries such as chemical, pharmaceutical, pesticide, food, feed, and agricultural products processing due to its unique advantages of high efficiency, low energy consumption, continuous drying, solvent recovery, small footprint, and simple operation.

The vacuum disc continuous dryer designed and produced by our company is an efficient and energy-saving continuous drying equipment that has been improved and innovated based on the absorption of domestic and foreign technologies. It has become a good choice for many production units and has brought more benefits and value to society.

Wet materials are continuously added to the pressure resistant hopper, and the materials are distributed into the material tank in turn through the upper vacuum ball valve. The upper and lower vacuum ball valves of the material tank are alternately opened and closed. The materials are continuously added to the first layer of the drying disc on the upper part of the dryer under the action of the mixing motor. The rake arm with rake blades rotates to make the rake blades continuously flip the materials, allowing the materials to fully absorb heat. The materials flow through the surface of the drying disc along the exponential spiral line. The materials on the small drying disc are transferred to the outer edge and fall to the outer edge of the large drying disc below. The materials on the large drying disc move inward and fall into the lower small drying disc from the middle discharge port. The large and small drying discs are alternately arranged up and down, and the materials can continuously flow through the entire dryer. The hollow drying disc Introduce heating medium inside. The heating medium enters the drying disc from one end and exits from the other end. The dried material falls from the bottom drying tray onto the cooled bottom layer of the shell, and is then transferred by the rake blade to the discharge port and discharged from the bottom material tank. It is then rotated through the upper and lower vacuum ball valves for discharge. The moisture evaporates and evaporates from the material, and is forcibly extracted by a vacuum pump. The solvent condenses through a condenser and enters a buffer tank for recovery. The entire operation process is carried out under negative pressure, and the moisture is then emptied.

（1） Easy regulation and strong applicability

By adjusting the thickness of the material layer, spindle speed, number of rake arms, and rake blade size, the drying process can be optimized.

Each layer of the drying tray can be separately filled with hot or cold medium to heat or cool the material, and the temperature control of the material is accurate and easy.

The residence time of materials can be precisely adjusted.

The material has a single flow direction, no backmixing phenomenon, uniform drying, stable quality, and does not require mixing.

（2） Simple and easy to operate

The operation of driving and parking the dryer is very simple.

After stopping the feeding, the scraper blades for conveying material can quickly empty the material inside the dryer.

Through the specialized large size inspection door mirror, careful cleaning and observation can be carried out inside the equipment.

（3） Low energy consumption

The material layer is very thin, the spindle speed is low, the system requires less power, and consumes less electricity.

Drying with conductive heat results in high thermal efficiency and low energy consumption.

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

Atmospheric pressure type: Due to the low airflow velocity and low humidity inside the equipment, it is difficult for dust to float to the top of the equipment. Therefore, the exhaust gas discharged from the top exhaust outlet contains almost no dust.

Sealed type: equipped with a party solvent recovery device, which can easily recover organic solvents from moist gases. The solvent recovery device is simple and has a low recovery rate. For flammable, explosive, toxic, and easily oxidizable materials, nitrogen can be used as a carrier gas for half cycle circulation to ensure safe operation. Specially suitable for drying flammable, explosive, and toxic materials.

（5） Easy installation and small footprint

The dryer is shipped as a whole and only needs to be lifted into place for easy installation and positioning.

Due to the vertical arrangement and installation of the drying tray layer, even if the drying area is large, the footprint is also very small.
