Experimental spray dryer composition
The experimental spray dryer is mainly composed of a primary and secondary effect filter, an electric heating box, a spray tower main body, a frequency conversion atomizer, a cyclone separator, an induced draft fan, a hot air pipe, and an electric control box. All parts are concentrated on a frame, with wheels at the bottom of the frame for easy movement. The interface is simple, and it can be used just by turning on the power. The design of the whole machine is compact and movable. The machine is self-contained and can be used without auxiliary facilities. It adopts PLC control, touch screen display, Chinese and English operation interface. It is suitable for the drying of heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc. Because the sprayed materials are only exposed to high temperature when sprayed into mist-like particles, they are only heated instantly, which can keep these active materials in After drying, the active ingredients remain undamaged. To
After the experimental spray dryer air passes through the filter and the heating device, it enters the hot air distributor on the top of the drying chamber. The hot air passing through the air distributor enters the drying chamber in a spiral shape and uniformly. At the same time, the material and liquid are sent to the drying chamber by the pump. The centrifugal spray head on the top of the drying chamber sprays the material liquid into very small mist droplets, which greatly increases the specific surface area of the material liquid and the hot air.
