2.7-110m2 Aluminum Hydroxide Hollow Paddle Dryer Machine Wedge shaped blades

2.7-110 ㎡ High Efficiency High Quality Aluminum Hydroxide Paddle Dryer for Different Country

Product introduction

Wedge-shaped hollow blades are densely arranged on the hollow shaft, and the thermal medium flows through the blades through the hollow shaft. The unit effective volume has a large heat transfer area. The temperature of the thermal medium ranges from - 40 ° C to 320 ° C, which can be water vapor or liquid type: such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat. Heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer of the reactor body. The heat transfer surface of the wedge-shaped blade has the function of self-cleaning. The relative movement of the material particles and the wedge-shaped surface can wash off the attached materials on the wedge-shaped surface, so that the clean heat transfer surface is kept in motion all the time.

Technical parameters

Applications 

It has been successfully used in the food, chemical, petrochemical, dyes, industrial sludge and other fields. Heat transfer equipment, cooled, stirred solution of the following characteristics makes it possible to complete the unit operations: calcination (low temperature), cooled, dried (solvent recovery), heating (melting), the reaction and sterilization. Stirring blades while the heat transfer surface, so that the heat transfer area per unit effective volume is increased, the processing time is shortened. Wedge-shaped blade heat transfer surface and having a self-cleaning function. Compression - expansion of the material mixture evenly mixing function. Material axially into a "plug flow" movement in the axial zone, material temperature, humidity, mixing gradient is very small.

Main feature:

1) Blade dryer low with energy consumption: As a result of indirect heating, no large amount hot air with lot of energy been carry away , high thermal efficiency.

2) Blade dryer unit has a huge effective heat transfer surface area, the smaller the size of the device. It greatly reduces the construction area and building space.

3) wide range of materials handling: the use of different media, both heat-sensitive materials can handle, but also handle high-temperature materials. Common media are: water vapor, thermal oil, hot water, cooling water (cooling) and so on. Can be continuous operation can be intermittent operation, can be applied in many fields.

4) Environmental pollution is small: carry the amount of air is very small, dust material entrainment rarely. For contaminated materials or solvent recovery conditions, closed-loop can be used.

5) low operating costs: the normal operation of the device, only 1 person / day. Low-speed mixing and reasonable structure. Low wear, low maintenance costs.

6) Stable operation: Due to the special compression-expansion stirring of the wedge blades, the particle composition of the material is in contact with the heat transfer surface. In the axial section, the temperature, humidity and the mixing temperature gradient of the material are small, and the heat transfer coefficient is large .
