1. 设备概述与原理

** Equipment Overview ** :

**设备概述**：

High-speed centrifugal spray dryer is an advanced equipment that atomizes liquid materials into tiny droplets by using a high-speed rotating centrifugal disc and completes the drying process quickly in a hot air environment.

高速离心喷雾干燥机是一种利用高速旋转的离心盘将液态物料雾化成微小液滴，并在热风环境中迅速完成干燥过程的*设备。

It is widely used in pharmaceutical, food, chemical, dyes, ceramic materials and other industries, can efficiently transform wet materials into powder or granular products, and the product particles are uniform, good solubility, high purity.

它广泛应用于制药、食品、化工、染料、陶瓷材料等行业，能够高效地将湿物料转化为粉末或颗粒状产品，且产品颗粒均匀、溶解性好、纯度高。

** Working principle ** :

**工作原理**：

The working principle of the high speed centrifugal spray dryer is based on the action of centrifugal force.

高速离心喷雾干燥机的工作原理基于离心力的作用。

The liquid material enters the high-speed rotating centrifugal disc through the feed tube, and is thrown out and atomized into tiny droplets under the action of centrifugal force.

液态物料通过进料管进入高速旋转的离心盘，在离心力的作用下被甩出并雾化成微小的液滴。

At the same time, after the hot air is heated to a predetermined temperature by the heater, it enters the drying chamber in the tangential direction and carries out sufficient heat and mass exchange with the atomized droplets, so that the water in the droplets quickly evaporates.

同时，热空气经过加热器加热至预定温度后，以切线方向进入干燥室，与雾化的液滴进行充分的热质交换，使液滴中的水分迅速蒸发。

The dried product enters the collection system with the air flow, and the tail gas is discharged after being treated by the dust removal device.

干燥后的产品随气流进入收集系统，尾气则通过除尘装置处理后排放。

The speed of the centrifugal disc can be adjusted according to the nature of the material and drying requirements to achieve the best atomization effect.

离心盘的转速可根据物料的性质和干燥要求进行调节，以达到*佳的雾化效果。
