What are the equipment characteristics of paddle dryer?

2022-07-23

1. Low energy consumption of paddle dryer: due to indirect heating, it does not carry a large amount of air to take away heat. The outer wall of the dryer is provided with an insulating layer. For paddle like materials, only 1.2-1.5kg steam is required to evaporate 1kg water.

2. Low cost of paddle dryer system: there is a huge heat transfer surface in the unit effective volume, which shortens the processing time and reduces the size of the equipment. It greatly reduces the building area and building space.
3. Wide range of materials: different thermal media can be used to treat both heat sensitive materials and materials requiring high temperature treatment. Common media include: steam, heat transfer oil, hot water, cooling water, etc. It can be operated continuously or intermittently, and can be used in many fields.
4. Little air pollution caused by the use of materials. The evaporation capacity of material solvent is very small, which is convenient for treatment. Closed circuit circulation can be adopted for contaminated materials or working conditions requiring solvent recovery.
5. Low operating cost: the equipment operates normally, only 1 hour / day · person. Low speed mixing and reasonable structure. The wear is small and the maintenance cost is very low.

6. Stable operation: due to the special compression expansion mixing function of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial range, the gradient of temperature, humidity and mixing degree of the material is very small, so as to ensure the stability of the process.
