Spray Dryer

Food & Biotech Engineers (India) Pvt Ltd offers a Spray Dryer. Spray drying is transformation of feed from a fluid state into dried particulate form by spraying the feed into a hot drying medium. It is a continuous particle-processing drying operation. The feed can be a solution suspension, dispersion, emulsion or slip. The dried product can be in the form of powders, granules, or agglomerates. Feed is finely atomised and introduced in the drying chamber along with hot air. During this residence time, the feed droplets loose its moisture to the hot air and are converted into dry powder particles. The dry powder falling on to the conical portion of drying chamber slides down to bottom of drying chamber with the assistance of vibrators/knockers and is collected in collection bag/bottle through the rotary valve located at the bottom of drying chamber. The air leaving the drying chamber entrains some of the dry powder, which is recovered in the cyclone separator and collected through rotary airlock. The air leaving the cyclone separator still has traces of dry powder, which is further recovered by scrubbing in wet scrubber or passing it through bag filter.
