The hollow shaft is densely arranged with a wedge shaped hollow blade, and the heat medium flows through the blade through the hollow shaft. The effective heat transfer area of the unit effective volume is very large, the heat medium temperature from -40 to 320 degrees Celsius, can be water vapor, also can be liquid type: such as hot water, heat conduction oil, etc.. Indirect conduction heating, without carrying air away heat, heat is used to heat the material. Heat loss is only through the thermal insulation layer to the environment. Wedge shaped blade heat transfer surface with self cleaning function. The relative motion of the material particles and the wedge shaped surface has a cleaning action, which can wash off the adhesive material on the wedge surface, so that the heat transfer surface can be kept clean during operation. The shell of paddle dryer is W type, and the shell is generally arranged between two and four hollow shafts. The shell is provided with a sealing end cover and an upper cover to prevent the material from leaking out and collecting the solvent vapor of the material. The discharge port is provided with a blocking plate to ensure the material level height, so that the heat transfer surface is fully covered by the material. The heat medium flows through the rotary joint, flows through the shell jacket and the hollow mixing shaft, and the hollow mixing shaft has different internal structure according to the type of the heat medium, so as to ensure the best heat transfer effect.
Paddle dryer has been successfully used in food, chemical, petrochemical, dyestuff, industrial sludge and other fields. Equipment heat transfer, cooling, mixing characteristics of the following units can be completed operation: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), reaction and sterilization. The stirring paddle is also a heat transfer surface, which increases the heat transfer area in the effective volume of the unit, and shortens the processing time. Wedge shaped blade heat transfer surface and self cleaning function. Compression - expansion mixing function to make the material mixture evenly. Material along the axis into a "piston flow" movement in the axial range, the material temperature, humidity, mixed degree gradient is very small.
The heat conducting oil as heat medium, can complete the work of calcined paddle dryer. Such as: two calcium sulfate (2H2O Ca2SO4) to the conversion of calcium sulfate and calcium sulfate (1/2H2O Ca2SO4). Sodium bicarbonate (NaHCO3) calcined into soda ash (Na2CO3) etc..
- pass into the cooling medium, such as water, cooling water can be used for cooling. Such as: used in blades of soda industry type alkali cooling machine, replace old-fashioned air cooling alkali cooling machine, energy saving and exhaust gas treatment equipment, reduce operating costs, but also can be used for titanium, nickel iron alloy powder and powder material cooling. In a single machine, the material can be cooled from 1000 to less than 40.
The function of drying, the main equipment, do not use hot air, the solvent recovery, energy consumption and environmental control are easy to deal with the ideal state. Is especially suitable for the solvent to be recovered, flammable and oxidation heat sensitive materials. Has been widely used in fine chemical, petrochemical, dye industry.
The axial range, temperature, humidity, mixed degree of uniformity, the equipment can be used for heating or melting, or some solid material reaction. In the compound fertilizer and modified starch industry have been successfully used. Paddle dryer can be used for the sterilization of food and flour. Large heating area within the effective volume of the unit, it will soon be heated to the temperature of the sterilization temperature, to avoid a long time to change the quality of the material.

The paddle dryer: due to low energy consumption of indirect heating, not a lot of air carrying away heat, drying and heat preservation layer is arranged on the outer wall, slurry materials, the evaporation of 1kg of water is only 1.22kg water vapor.
The paddle dryer system construction cost is low: the unit effective volume has great heat transfer surface, shortens the processing time, the size of the equipment becomes small. Greatly reduced the size of the building and building space.
Processing range: - materials with different heating media can handle heat sensitive materials, can also deal with the need for high temperature processing materials. Commonly used media are: water vapor, heat conduction oil, hot water, cooling water, etc.. Both continuous operation can be intermittent operation, can be applied in many areas.
The environmental pollution is small: do not use carrying air, dust material entrainment rarely. Material solvent evaporation is very small, easy to deal with. In the case of contaminated materials or the need to recycle the solvent, the closed circuit can be used.
The operation cost is low: the normal operation of the equipment, only 1-2 / day. Low speed mixing and reasonable structure. Wear small, low maintenance costs.
The stable operation: because the wedge blade special compression - expansion stirring, the particles fully with the heat transfer surface contact in the axial range, material temperature and humidity, the mixed gradient is very small, so as to ensure the stability of the process.
