The temperature state of the material particles in the flash dryer is affected by a combination of factors. First of all, the material particles usually have a certain initial temperature when they enter the dryer. During the drying process, the particles exchange heat with the hot air, absorbing heat and evaporating water. As a result, the temperature of the material particles gradually increases as the drying process progresses.
Secondly, the temperature of the material particles is also affected by the internal temperature environment of the dryer. Factors such as the temperature of the hot air of the dryer, the contact time between the material and the hot air, and the degree of mixing of the hot air with the material will affect the temperature of the material particles. For example, the higher the temperature of the hot air, the more heat absorbed by the material particles and the higher the temperature.
In addition, the temperature of the material particles is also related to its own physical and chemical properties. For example, the thermal conductivity, specific heat capacity, and water evaporation rate of a material all affect its temperature state.
In summary, the temperature state of material particles in the flash dryer is a complex and changeable process, which is affected by many factors such as the initial temperature, hot air temperature, material properties and the internal environment of the dryer. In order to obtain the best drying effect, it is necessary to reasonably control the operating parameters and environmental conditions of the dryer according to the characteristics of the material and the drying requirements.
