1. Introduction and application:
Continuous hollow blade paddle dryer is applied to dry or cool paste, particles, powdery materials, and slurry state materials. It performs the process of drying, cooling, heating, sterilizing, reacting and combustion under low temperature. The special agitating and heat transferring blades achieve high heat transfer efficiency and provide self-cleaning function.

2. Working Principle:
Hollow chock shaped blades or wedge-shaped blades are concentrated on the hollow shaft. Heating media flows through the blades from the hollow shaft. The heat transfer area in the effective volume is very high.
The temperature range of heating media is -40 ºC to 320 ºC. Heating source could be steam, liquid state, such as steam, thermal oil etc.
Indirect heating, there's no heat carried out by air. All heat is utilized to dry the materials except the lost of heat insulation layers. The surface of chock shaped blade has self-cleaning function.
The relative movements of the product particles and the chocked shaped blades surface might clean the materials attached to the blades surface, so the heat transferring surface is clean during working.
The shell of hollow blade paddle dryer is Ω shape. 2 or 4 pieces of hollow stirring shaft are usually equipped in the shell. To avoid any leakage of materials and dust, there're sealed terminal cover and top cover with the shell. The heat transferring media flow through the rotation connector, jacket's shell and hollow stirring shaft.
The heat transfer medium passes through the rotary joint, through the housing jacket and hollow shaft, the hollow mixing shaft in accordance with the type of the heat media has a different internal structure, to ensure optimum heat transfer effect.

3. Features:
(1) Low energy consumption: No heat carried out by the air due to indirect heat. There's no heat insulation layer with the exterior wall of the dryer. It consumes 1.2kg steam to evaporate 1kg water for drying slurry materials.
(2) Low cost of the blade dryer system: the unit effective volume has a large heat transfer surface, so the processing time is shorted, the size of the equipment becomes small. It greatly reduces the floor area and building space.
(3) Handling wide range of materials: Heat sensitive material and the materials to be processed under high temperature might be processed with different heating media.
(4) Common media are: steam, thermal oil, hot water and cooling water, etc. (5) Continuous operation or intermittent batch operation, widely used in many fields.
(6) Environmental pollution is less: Without any carrying air, very few powder is carried out. Evaporation of the solvent material is very small, easy to handle. For the materials that might cause pollution or the solvent to be recovered, it might adopt sealed circulation.
(7) Low operating cost: the structure.1 hour/day for the operator is enough for normal operation. Low stirring speed and reasonable structure makes a low maintenance cost.
(8) stable operation: the wedge-shaped blades will do special compression, expansion of stirring effect, the material particles will fullly contact with the heat transfer surface in the axial section. The difference of the temperature, humidity and mixing effect are very small in the different axial area, so to ensure the stability of process.
(9) Low speed will not break the granular materials or sliced materials.

Paddle dryer has been successfully used in food, chemical, petrochemical, dyes, industrial sludge and other fields. Heat transfer equipment, cooling, mixing characteristics makes it possible to complete the following unit operations: The Burning (low temperature), cooling, drying (solvent recovery), heating (melting), response and sterilization.
Used to do medium heat blade dryer work to be completed by low-temperature combustion. Such as: calcium sulfate dihydrate (Ca2SO4 · 2H2O) combustion into calcium sulfate hemihydrate (Ca2SO4 · 1/22H2O). Sodium bicarbonate (NaHCO3) into calcined soda ash (Na2HCO3) and so on.
Pass into the cooling medium, such as water, salt water, etc. Eg: used in soda ash industry paddle cool base machine, replace the old air-cooled cooler base machine, saving energy and exhaust gas treatment equipment, reducing operating costs.
In need of recycling solvent, flammable oxidation sensitive materials especially adapted. Has been widely used in fine chemical, petrochemical, dye industry.
Axial interval, temperature, humidity, degree of mixing uniformity, making the device used to heat or melt, or some solid material reactions. In the fertilizer and modified starch industry have been used successfully. Blade dryer can be used to sterilize food and flour processing. Unit effective volume large heating area, will soon be heated to sterilization temperature, avoiding prolonged heating to change the quality of materials.
