View Product Description

Sewage Industry Double-Shaft Vacuum Hollow Paddle Dryer

Paddle dryer consists of two rotating shafts with wedged paddles, jacketed drying chamber, drive motor and support frame. The drying process is completed in sealed drying chamber to prevent pollution by evaporated.

Paddle dryer is indirect heating drying processor. Heat medium can be steam, hot water or thermal oil which can flow through the hollow shafts and paddle via revolving joints, as well as jacketed drying chamber. Wet material is evenly fed into the drying chamber by screw feeder. With the rotation of two shafts and paddles, wet material is completely mixed and stirred to contact with the hot surface and move towards the discharge and heat transfer happens and moisture evaporates rapidly.


Product Working Principle

CHPD series Paddle Dryer / Processor are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. They are used for drying, heating, cooling, pasteurization, crystallizing, and reacting of pastes, cakes, powders, and granules.

Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing and optimize heat transfer. The use of hollow discs and drying chamber heating jacket for heat transfer results in a compact machine. The heat transfer medium: steam, hot water or hot oil is isolated from the process mass. The KJG series Paddle Dryer provides a reliable and efficient method for drying slurry, filter cakes and centrifuge concentrates.

Technical Advantage

1) High thermal efficiency which can reach 95%
2) Heat transfer medium does not contact the product.
3) Gas is not used to convey the product. Off-gas flow is minimal.
4) Precise control of temperature
5) Uniform product quality, through mixing and movement of the product
6) Continuous process on a once-through basis
7) High heat transfer area to process volume ratio - reduced floor space
8) Easy to operate, requires minimal attention
9) Safer than direct drying when processing combustible material
10) Simple durable design for easy and low maintenance
11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.


HEAT SOURCES(Temperature at 180ºC - 250ºC)
Heating by Steam
Steam enters the hollow shaft through a rotary joint and is evenly distributed to all paddles. Condensate is removed with each revolution.
Heating by Hot Oil(thermal fluid)

Hot oil(thermal fluid) enters and exits the hollow shaft through a rotary joint. Pressure from the supply pump forces liquid through the hollow paddles.


Product Application
Blade dryer has been successfully used in food, chemical, petrochemical, dye, industrial sludge and other fields. Equipment heat, cooling, mixing features make it to complete the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), response and sterilization. Mixing blades at the same time the heat transfer surface, the effective volume per unit area of heat transfer increases, reducing the processing time. Heat transfer surfaces in wedge-shaped blades with self-cleaning function. Compression - Expansion mixing features make the material mixed uniformly. Material along the axis into a "plug flow" movement, in the axial zone, the material temperature, humidity, mixing a very small degree of gradient.
1. Conducting oil to do with the heat medium, blade dryer to complete the work of low-temperature calcination. Such as: calcium sulfate dihydrate (Ca2SO4 · 2H2O) calcined into calcium sulfate hemihydrate (Ca2SO4 · 1/2H2O). Sodium bicarbonate (NaHCO3) into calcined soda (Na2CO3) and so on.
2. Pass into the cooling medium, such as water, salt, etc. can be used to cool the cooling. Such as: use of soda ash industry in blade-type cooler base machine to replace the old air-cooled cooler base machine, saving energy and exhaust gas processing equipment, lower operating costs, but also for titanium, nickel alloy powder and all kinds of powder granular materials cooling. On a single machine where the material can be cooled from 1000 °C to less than 40 °C.
3.Dry, the main function of equipment, do not use hot air to solvent recovery, energy consumption, environmental control is easy to deal with the ideal state. On the need to recover solvents, heat-sensitive materials, particularly flammable adapt easily oxidized. Has been widely used in fine chemical, petrochemical, dye industry.
4. Axial range, temperature, humidity, mixing degree of uniformity, so equipment can be used to heating or melting, or some solid material response. In the compound and modified starch industries have been successfully used. Blade dryer can be used to carry out sterilization of food and flour. Unit within the effective volume of a large heating area, will soon be material heated to sterilization temperature, to avoid prolonged heating change the quality of materials.
