Characteristics of residence time in single-stage continuous fluidization dryer

The characteristics of residence time in single-stage continuous fluidization drier are mainly as follows:

Wider distribution of residence time: due to the structure and working principle of the fluidization drier, the residence time of the material in the drier will have certain differences, and the distribution of residence time is wider.

Residence time is related to particle size: smaller particles have shorter residence time in the dryer, and larger particles have longer residence time in the dryer. Therefore, the residence time of the material can be estimated on the basis of particle size.

Residence time is related to feeding speed: the faster the feeding speed, the shorter the residence time of the material in the dryer; the slower the feeding speed, the longer the residence time of the material in the dryer.

Residence time and drying conditions: different drying conditions will affect the residence time of the material in the dryer. For example, when a higher air flow rate or a higher drying temperature is used, the residence time of the material may be shortened.

Residence time is related to the nature of the material: different nature of the material in the same fluidization dryer residence time may be different. For example, materials with strong hygroscopicity may need longer residence time to achieve the same drying effect.

In summary, the characteristics of the residence time in a single-stage continuous fluidization dryer is the result of a combination of factors, for specific materials and drying conditions, it is necessary to determine the optimal residence time by experiment.
