Hollow paddle dryer is a kind of horizontal stirring dryer with heat conduction. Because the internal hollow mixing blade is similar to the paddle, it is called hollow paddle dryer. Because the heat required by the drying equipment is indirectly heated by heat conduction, only a small amount of gas is needed to take away the moisture in the drying process, which greatly reduces the loss of this part of heat taken away by the gas and improves the utilization rate of heat. The dynamic drying hollow blade dryer is an energy-saving drying equipment. It is suitable for the drying of granular and powder materials, and it can also dry the paste materials smoothly.
Paddle dryer is a kind of horizontal agitating dryer, which is mainly conductive. The main structure is a W-shaped shell with a jacket. A pair of hollow low-speed rotary hollow shafts are installed in the shell. A number of stirring blades are welded on the shaft. The jacket and the hollow stirring blades are filled with heat carriers. The two heating surfaces heat the materials at the same time. The heat carrier is usually fed from the middle of the dryer and discharged from the other side through the surface of the material layer in a stirred state.
Wedge shaped hollow blades are densely arranged on the hollow shaft, and the thermal medium flows through the blades through the hollow shaft. The heat transfer area in the unit effective volume is very large, and the temperature of the heat medium ranges from - 40 ° C to 320 ° C. It can be water vapor or liquid, such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat, heat is used to heat materials, heat loss is only through the body insulation layer to the environment. The heat transfer surface of wedge-shaped blade has self-cleaning function. The relative movement of material particles and wedge-shaped surface produces washing effect, which can wash away the attached materials on wedge-shaped surface and keep clean heat transfer surface all the time

Special Design of Our Hallow Blade Dryer
* Compact structure: The main heat transfer component of the dryer is the shovel shaped blades, which are densely packed and arranged crosswise on a fixed rotating shaft at specified intervals, resulting in higher heat transfer per unit volume. For this reason, this device has a very compact structure and a small footprint.
* High heat transfer efficiency: Due to the excellent continuous mixing and stirring of raw materials, the relatively rotating shovel shaped blades and inclined blade surfaces, as well as the heating and cooling of the body, ensure that all surfaces in contact with the product can evenly transfer heat energy.
* Self cleaning performance: Due to the relative rotation of the blade movement, they have a continuous self-cleaning effect on the nearby inner surface. The products that adhere to each other and accumulate on the blades can be removed and re-entered into the production process.
* Simple control: The drying process and residence time can be easily checked, controlled, and adjusted. They can be individually set and adjusted based on the physical properties of the dried product, including the number of shafts or blades, rotational speed, temperature of the heat exchanger, and drying time.
* The generated dust and odor are relatively small: Due to the small gas flow used during the drying process, the dust and odor that can be generated are also very small. Therefore, the vacuum cleaner or deodorizer used in conjunction with it is also very small or unnecessary to use at all.
* Almost no wear and material loss: The rotational speed of the blades is very low, only 10 to 40 revolutions per minute, which effectively avoids wear and rapid wear of machine equipment caused by wear. In addition, the risk of metal material rupture is also minimized.
* Suitable for drying products with high humidity: Tue to the use of paddle type drying elements and continuous mixing and stirring, it can dry materials with high viscosity and high humidity. Its structural design avoids product accumulation in dead corners and overheating or spoilage caused by product accumulation.
