4 Shaft Blade Hollow Paddle Dryer

1. Compact structure: the main heat transfer components of the dryer are shovel-shaped blades, which are dense and intersected on fixed rotating shafts at specified intervals, so the heat transfer per unit volume is relatively high. For this reason, the structure of the equipment is very compact, small area.

2. High heat transfer efficiency: due to good mixing and stirring of raw materials, heating and cooling of the relative rotating blade and sloping blade surface and the body, all surfaces in contact with the product can transfer heat energy uniformly.

3. Self-cleaning performance: because the blade motion is relative rotation, they play a continuous self-cleaning effect on the inner surface nearby. Products that are bonded and stacked on the blades can be removed and re-entered the production process.

4. Simple control: drying process and residence time can be easily checked, controlled and adjusted. They can be individually set and adjusted according to the physical properties of the dried product, and the number of shafts or blades, the rotational speed, the temperature of the heat transfer body and the drying time can be set and adjusted.

5. Less dust and odors: the amount of dust and odors that can be produced is small because the flow of gas used in the drying process is small. As a result, the associated vacuum cleaner or deodorizer is small or not required at all.

6. Suitable for drying of high humidity products: the use of blade drying elements and continuous mixing allows drying of highly viscous, high humidity materials. It is designed to avoid product retention at dead ends and overheating or spoilage caused by product retention.

7. There is little wear and wear: the blade has a low rotational speed of only 1040 revolutions per minute, which effectively avoids abrasion and rapid wear of machine tool equipment caused by abrasion. In addition, the fracture risk of metallic materials is minimized.
