What Is the Future Development Trend of Hopper Dryerdw?

Hopper dryer is a device used to perform drying operations in which the moisture (generally water or other volatile liquid components) in the material is vaporized and escapes by heating to obtain a solid material with a specified moisture content.

What is the principle of Hopper dryerd?

Hopper dryerd is the process of using heat energy to vaporize the moisture (water or other solvent) in the wet material, and the water vapor or steam is taken away by airflow or removed by vacuum pump to obtain a solid product. When drying wet materials, there are two drying processes, one is the surface vaporization process, heat transfer from the surrounding environment to the surface of the material, so that the surface moisture evaporation and the other is the internal diffusion control process, the internal moisture transfer to the surface of the material, and then evaporate. The drying rate of the material is controlled by the slower one of the above two processes.

Hopper dryerd what elements to consider when selecting?

1. physical and chemical properties of materials - morphology, water content, water nature, water of crystallization, particle size, weight, viscosity, heat sensitivity, softening point, phase change point, thixotropy, toxicity, corrosiveness, odor, flammability, explosiveness, electrostatic, permeability, agglomeration, easy to crush crystals or particles...

2. Drying characteristics of materials - drying curve, critical moisture content, equilibrium moisture content under the proposed drying conditions.

3. Drying output requirements and vision planning.

4. The commodity value of the material and the influence of drying effect on it. Such as product moisture, pollution, temperature, wear and tear, pulverization, crushing, rehydration... The impact of the product value.

What is the future development trend of Hopper dryerdw?

The future development of dryer will be developed and improved under the in-depth study of drying mechanism and material drying characteristics, mastering the optimal operating conditions for different materials; in addition, large-scale, high-intensity and high-economy, as well as improving the adaptability to raw materials and product quality, are the basic trends of dryer development; at the same time, further research and development of new high-efficiency and adaptable dryers with special requirements, such as combined dryer, microwave dryer and far-infrared dryer, microwave dryer and far-infrared dryer, etc. The development of Hopper dryer should also pay attention to energy saving and comprehensive utilization of energy, such as adopting various joint heating methods, transplanting heat pump and heat pipe technology, developing solar dryer, etc.; it should also develop automatic control technology of the dryer to ensure the realization of optimal operating conditions; in addition, as human beings attach importance to environmental protection, improving environmental protection measures of the dryer to reduce dust and exhaust gas leakage, etc. will also be the direction of in-depth research.
