Effective pressure is the key factor affecting the spraying effect and drying efficiency of centrifugal spray dryers.

Centrifugal spray dryer is a kind of drying equipment widely used in chemical, pharmaceutical and food industries, and its effective pressure is one of the key factors affecting spray effect and drying efficiency.

Effective pressure refers to the centrifugal spray dryer in normal working conditions, the pressure generated by the nebulizer, which is related to the nature of the material, the performance of the nebulizer and the parameters of the drying medium and other factors. The size of the effective pressure directly affects the atomization effect of the sprayer and the flow and temperature of the drying medium.

In the design and use of centrifugal spray dryer, according to the characteristics of the material and production process requirements to determine the appropriate effective pressure. Effective pressure is too low will lead to the material can not be fully atomized, affecting the drying effect; and effective pressure is too high will lead to drying medium flow is too large, resulting in energy waste and equipment wear.

In order to increase the effective pressure of centrifugal spray dryer, some measures can be taken. For example, according to the material characteristics of the choice of suitable sprayer model and parameters, in order to rise the atomization effect of the material; optimize the structural design of the equipment, rise the overall performance and stability of the equipment, in order to maintain the stability of the effective pressure; improve the parameters of the drying medium, such as the rise of the drying medium temperature and flow rate, in order to accelerate the speed of drying and the rise of drying effect.

In short, the effective pressure of centrifugal spray dryer is one of the important factors affecting the spray effect and drying efficiency. In the selection and use of equipment, need to be based on the actual situation for comprehensive consideration and adjustment, in order to achieve good drying effect and economic benefits.
