1、 Product Overview
The laboratory centrifugal spray dryer is an efficient drying equipment specially designed for scientific research and small production, which is widely used in the fields of bio pharmaceutical, food chemical, etc. It achieves rapid drying and obtains uniform powdered products by atomizing liquid materials and fully contacting them with hot air. This device is particularly suitable for handling heat sensitive substances and can effectively maintain the active ingredients of the material.
2、 Working principle
Firstly, the liquid material is pumped into the atomizer of the equipment, and under the action of high-speed rotation, the liquid is dispersed into tiny droplets. These droplets then enter a drying chamber filled with hot air, where they undergo intense heat exchange with the hot air. The rapid evaporation of water causes the droplets to dry into solid particles in a short period of time. The dried particles are collected by a separation device, while the exhaust gas is purified and discharged. The entire process achieved an efficient transition from liquid to solid state.
