China Hollow Paddle Dryer - Energy-Saving Continuous Dryer from Reliable Suppliers and Factory
Principle
There are wedge-shaped hollow paddles in hollow axis, and heat medium is from -40°C to 320°C, the heat medium is steam or hot air or heat conduction oil and so on. Indirectly heating way does not take the energy, so the energy is used for heating material. The energy loss is only heat emission of heat-keeping layer. The transferring heat of wedge-shape side takes cleaning actions. It can clean waste material in wedge-shaped size. The body of wedge-shaped hollow paddle dryer is W shape. There are 2-4 hollow mixing axes in the body. In order to avoid discharging material dust and to collect material solvent, there is a sealed cover on top of body. A baffle is on the outlet of discharging material, in order to keep the height of materials. The heat medium (such as steam or thermal oil) will flow into chamber jacket and hollow mixing axis through rotary joint. Hollow mixing axis has different inner structures according to different types of heat medium, which will ensure of best heat transfer efficient.

Features
Big heat transfer area, compact construction and less installing area.
Low energy consumption: as the heat flow is indirect, there is no large volume of sweep gas flow through the unit, which will carry heat away from dryer. Take slurry as example, heat requirement maybe as low as 1.2kg of steam/kg for evaporating 1kg water in hollow paddle dryer.
Paddle can be cleaned by itself during operating, which will improve heat transfer efficiency.
Wide variety of process problems can be solved by using any kinds of heating source. It is specially suitable for drying heat sensitive materials and high temperature materials. The normal heat transfer medium can be steam, heat transfer oil, hot water, as well as cooling water etc. The dryer can be used for continuous or batch processing. It has been widely used in many industry areas already.
Stable operating continuously: Because of the special compression and inflation of agitation function of paddle dryer, the material grains touch the heat-transfer area thoroughly. Within the axis direction, the temperature, moisture, mixture and grades of the materials is very small so as to guarantee the stability of whole process.
Low labor and maintenance expense: Only need 1 person per 1 day for 1 dryer which saves a lot of labor cost for customer. With our intelligent design and good manufacturing, the equipment is indefectible thus maintenance cost greatly saved.
