　　Hollow blade dryer

：On the basis of absorbing technology, our company has made improvements and optimized the design of the wedge shapeHollow blade dryerIt can indirectly heat or cool paste like, granular, powdered, and slurry like materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature calcination. The special wedge-shaped stirring heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of the heat transfer surface.

　　Hollow blade dryer：Wedge shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area within a unit effective volume is large, and the temperature of the heat medium ranges from -40 ° C to 320C. It can be steam or liquid, such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry away heat with air, and the heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation layer of the device body. The wedge-shaped blade heat transfer surface has self-cleaning function. The relative motion between material particles and the wedge-shaped surface produces a washing effect, which can wash away the wedge-shaped surface Attach materials to maintain a clean heat transfer surface during operation. The shell of the blade dryer is W-shaped, and generally two to four hollow mixing shafts are arranged inside the shell. The shell has sealed end caps and upper caps to prevent material dust leakage and collect material solvent vapor. Set up a stopper at the discharge port to ensure the height of the material level, so that the heat transfer surface is covered by the material and fully utilized. The heat medium flows through the shell jacket and hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures according to the type of heat medium to ensure good heat transfer effect.

Features:

Wide range of material processing: using different heat media, it can handle both thermosensitive materials and materials that require high-temperature treatment. Common media include steam, thermal oil, hot water, cooling water, etc. It can operate continuously or intermittently and can be applied in many fields.

<>Low environmental pollution: No use of portable air, minimal dust and material entrainment. The solvent evaporation of the material is very small, making it easy to handle. For materials that are contaminated or require solvent recovery, closed-loop circulation can be used.

Low operating costs: The device operates normally with only 1-2 people per day. Low speed stirring and reasonable structure. The wear and tear is small, and the maintenance cost is very low.

Stable operation: Due to the special compression expansion stirring effect of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial range, the temperature, humidity, and mixing gradient of the material are very small, thereby ensuring the stability of the process.

The blade dryer has low energy consumption: due to indirect heating, it does not carry a large amount of air to take away heat. The outer wall of the dryer is also equipped with an insulation layer. For blade shaped materials, only 1.22kg of water vapor is needed to evaporate 1kg of water.

The blade dryer system has low cost: it has a huge heat transfer surface per unit effective volume, which shortens the processing time. The reduction in equipment size greatly reduces the building area and space.
