Large-Scale Food and Chemical Drying Machines

The hollow paddle dryer is a horizontal stirring dryer that uses heat conduction. It is named the hollow paddle dryer because its internal hollow stirring blades are shaped like paddles. The heat required by this drying equipment is indirectly heated through heat conduction. During the drying process, only a small amount of gas is needed to carry away the moisture, which greatly reduces the loss of heat carried away by the gas and improves the heat utilization rate. The dynamic drying hollow paddle dryer is an energy-saving drying equipment, suitable for drying granular and powdered materials, and can also smoothly dry paste-like materials.

Features:
1. Compact structure: The main heat transfer component of the dryer is the shovel-shaped blades, which are densely arranged at certain intervals on a fixed rotating shaft, thus achieving a relatively high heat transfer capacity per unit volume. For this reason, the structure of this equipment is very compact and it occupies a small area.
2. Efficient heat transfer: Due to the continuous mixing of raw materials, the relatively rotating shovel-shaped blades and the inclined blade surfaces, as well as the heating and cooling of the machine body, all surfaces in contact with the product can conduct heat uniformly.
3. Self-cleaning performance: Due to the relative rotation of the blades, they continuously self-clean the nearby inner surfaces. The products adhering to the blades and accumulating can be removed and re-enter the production process.
4. Easy control: The drying process and residence time can be simply inspected, controlled and adjusted. The number of shafts or blades, rotational speed, temperature of the heat transfer medium and drying time can be set and adjusted respectively according to the physical properties of the dried products.
5. Less dust and odor generated: Due to the small gas flow rate used in the drying process, less dust and odor are produced. Therefore, vacuum cleaners or deodorants are rarely or never needed.
6. Suitable for drying materials with high humidity: Due to the use of paddle drying elements and continuous stirring, it can dry materials with high viscosity and high humidity. Its structural design prevents materials from accumulating in dead corners and avoids overheating or damage caused by material accumulation.
7. Almost no wear and material loss: The blade speed is extremely low, only 10 to 40 revolutions per minute, effectively avoiding wear and rapid depletion of machine tools and equipment. Caused by wear and tear. In addition, the risk of fracture of metallic materials has also been reduced to the minimum.
