喷雾干燥塔 多级干燥机 的喷雾干燥塔

FSD Minor™ 喷雾干燥机是 FSD™ 喷雾干燥塔系列中最小的一款,用于研发和小规模生产。它适用于生产粗粒、复聚、自由流动和无尘的粉末。

干燥塔底部配备一体式流化床,FSD™ 喷雾干燥机将喷雾和流化床技术结合成稳妥的工艺流程,单个工序即可完成干燥和复聚。这样获得的颗粒结构可与一串葡萄相媲美。该技术尤其适用于食品应用,包括粘性、吸湿、芳香剂和热敏感产品

干燥工艺

SSP型 多级干燥机 1200x675

在初步干燥阶段,浓缩物通过位于干燥气道中的顺流喷嘴雾化。空气通过空气分布器高速垂直进入喷雾干燥塔,确保雾化液滴与干燥空气实现最优混合。在向下通过干燥塔腔室的垂直流动过程中,蒸发过程即启动。在此初级干燥阶段,颗粒将不会完全干燥。
At high moisture contents, the powder will exhibit high thermo plasticity and become very sticky. However, the air flow in the FSD™ spray dryer is designed to prevent particles from sticking to the drying chamber leading them directly to the integrated static fluid bed for second-stage drying. If the carbohydrate and/or fat contents of the powder are high, cold air will be used to pre-cool the product. The integrated static fluid bed is supplied with air at a velocity sufficient for fluidizing the product and for adapting the temperature for the second stage drying. The drying air from both primary and second-stage drying leaves the chamber from the top.

Agglomerated powders are in high demand as they will frequently have improved flowability and dispersibility compared to fine powders; and, moreover, they are less dusty.
