DG  Air Stream Drying Machine (Air stream dryers ) (Ring Dryer)( Air cooler)

Preface

DG Series Air Stream Dryer is drying plant for to dry maize, potato alike and other starch material processed by wet method after dewatering process. It's also for to dry heat sensitive powder or slice state material with fast speed.

Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.

In the dryer, high-speed hot air stream sustain raw material in the suspending state, then the material is dried. Since air stream speed is very high, and material is suspending in air stream, the heat transfer surface between air and solid is large, heat transfer rate is high, and drying time is short(usually within several seconds). It’s specially suitable for drying heat sensitive materials.

In drying process, clean cool air is heated by air heater, and mixed with wet starch sent by spiral feeder and material raiser. Wet starch is dried momentarily. Dry starch is discharged though centrifuge separator and star shape unloader . Exhaust air is let out into atmosphere.

Pneumatic coolers are a simple and reliable method of cooling and conveying dried product. In many instances ambient air will achieve the desired cooling duty. Where required, greater cooling capacity and a finer degree of control can be achieved with conditioned air at a controlled humidity and temperature.
