Products Description
The SED-10PG-H is a centrifugal spray dryer for converting pumpable liquids into powder. The original equipment specification includes dairy products among its applications. The dryer combines a filtered air supply, an electrically heated drying chamber and a cyclone collector on a common frame. A side-mounted control panel provides access to the settings used during a drying run.
Feed delivery and drying air
A peristaltic pump delivers filtered liquid to the rotary atomizer at the top of the chamber. Adjusting the pump changes the amount of liquid delivered to the atomizer. The rotating disc disperses the feed into fine droplets. Filtered air passes through the heater and enters the tower through a distributor. The drying air and droplets travel in the same direction through the chamber. Moisture evaporates along that path and the remaining solids form powder.
Powder collection
Powder separates from the drying air in the chamber and cyclone. A collection vessel receives the recovered powder, while the exhaust fan draws moisture-laden air away from the dryer. The chamber has a viewing port for checking the process with the door closed. The spray, drying and collection assemblies use stainless steel construction.
Monitoring a food drying run
The touchscreen supports automatic and manual control. The operator can monitor the inlet and outlet temperatures and adjust the feed rate and temperature settings to suit the liquid. Temperature control uses feedback from the dryer to regulate heat. A heater interlock requires the fan to be running before heating can start.
When processing a dairy feed, the operator selects conditions based on the feed composition and checks the powder against the intended moisture and particle characteristics. The adjustable feed and heat controls make it possible to compare operating settings while using the same chamber and powder collection arrangement.
