当固体物料表面水的蒸汽压大于干燥介质中水蒸汽的分压时,物料表面的水分就会不断汽化而进入空气,而物料内部水分不断扩散到物料表面。
When the vapor pressure of the water on the surface of the solid material is greater than the partial pressure of the water vapor in the drying medium, the water on the surface of the material will continue to vaporize and enter the air, and the water inside the material will continue to diffuse to the surface of the material.
干燥推动力为物料表面水的蒸汽压与干燥介质中水蒸汽的分压的差值。
The drying driving force is the difference between the steam pressure of water on the material surface and the partial pressure of water vapor in the drying medium.
针对于近来我们广大的客户关于干燥机上所选择的一些疑问,我们的工程师总结了以下的在选择干燥设备时候要考虑到的因素,希望能对广大的客户在选择的时候有个参考依据:
In view of our customers' questions about the selection of dryer recently, our engineers summarized the following factors to be considered in the selection of drying equipment, hoping to have a reference basis for our customers in the selection:
1.干燥机的生产能力,物料的进给方式(间歇/连续)
1. Production capacity of dryer and feeding mode of materials (intermittent / continuous)
2.湿物料的物理,化学及生化特征,以及对产品的质量要求;
2. Physical, chemical and biochemical characteristics of wet materials and quality requirements for products;
3.顺流或者逆流生产工艺
3. Downstream or countercurrent production process
4.原料和产品的含量
4. Content of raw materials and products
5.干燥动力学特征,湿物料的吸湿等温线
5. Drying kinetic characteristics, moisture absorption isotherm of wet materials
6.质量参数(物理,化学,生化);
6. Quality parameters (physical, chemical, biochemical);
7.安全方面,例如着火和爆炸危险,毒性;
7. Safety aspects, such as fire and explosion hazards, toxicity;
8.产品价值
8. Product value
9.自动控制方面的要求
9. Requirements for automatic control
10.产品毒性学特征
10. Toxicological characteristics of products
11.翻动率,生产能力可调性
11. Turnover rate, production capacity and adjustability
12.燃料的类型和消耗,电力消耗
12. Fuel type and consumption, power consumption
13.环保法规,对环境的污染性,以及生产的安全性等等
13. Environmental protection regulations, environmental pollution, production safety, etc
14.工厂的空间,设备在车间的放置,检修空间的余留等
14. Plant space, equipment placement in the workshop, remaining maintenance space, etc
15.行业性考虑:对于食品和生物制品的干燥需要遵守GMP法规和卫生设备的设计及操作要求。
15. Industrial considerations: the drying of food and biological products needs to comply with GMP regulations and the design and operation requirements of sanitary equipment.
