KJG Series Hollow Blade Dryer
KJG Series Hollow Blade Dryer
Detailed description
Overview:
The product can paste, granular, powder, paste material indirect heating or cooling, to be completed by drying, cooling, heating, sterilization, reaction, low temperature combustion unit operation. Wedge-shaped mixing device in a special heat transfer blade, has a high heat transfer efficiency and heat transfer surface self-cleaning function.
Densely lined with wedge-shaped hollow shaft hollow blades, heat medium through the hollow axial blades. Unit effective volume large heat transfer area, heat medium temperature from -40 ℃ -320-40 ℃, the water can also be liquid-type: such as hot water, thermal oil, etc. Indirect conduction heating, no air to carry away the heat, the heat are used to heat the material. Body heat loss is only through the device's thermal insulation to the environment. Wedge-shaped blades with cleaning heat transfer surfaces. Material particles and the relative movement of the wedge-shaped face wash effect can wash off the wedge-shaped surface attachment material, so that operation has maintained a clean heat transfer surfaces. Blade dryer for the Ω-shaped shell, the shell of the general arrangements for two to four hollow shaft. Shell and cover with sealing cover to prevent dust leakage of material and fully functional. Heat transfer medium through the rotary joint, through the shell jacket and the hollow shaft, hollow shaft according to the type of thermal media have different internal structures to ensure optimal heat transfer.
Features:
1, blades dry and low energy consumption, due to indirect heat, not a lot of space to carry
2, gas heat away, then set the dryer wall insulation, the slurry material, only a small amount of heat evaporate 1kg of water.
3, blade dryer system costs low, the unit has a huge effective volume of the heat transfer surface, shortening the processing time, the device size becomes smaller. Would greatly reduce the building area and building space.
4, dealing with a wide range of materials: using a different medium heat, can handle heat-sensitive materials, but also dealing with high temperature materials. Commonly used media are: water, steam, thermal oil, hot water, cooling water. Continuous operation can also be intermittent operation can be applied in many fields.
5, environmental pollution: do not use portable air entrained powder material rarely. Materials
Solvent evaporation is very small, easy to handle. To have contaminated materials or be recycled solvent conditions, can be closed loop.
(D) low operating costs: the device to normal operation, only 1 hour / day * person. Low-speed mixing and reasonable structure. Small amount of wear and tear, maintenance costs low.
(E) operation and stability: As the wedge-shaped blades special compression - expansion of stirring, the material particles sufficient surface contact with the heat transfer in the axial range, the material temperature, humidity, mixing gradient is very small, thus ensuring process stability.
