Rotary Sugar Dryer & Cooler

Sugar is a common product found in kitchens worldwide. From its familiar appearance to its unmistakable taste, commercial sugar of today is easily recognizable. But even a staple as basic as sugar requires a great deal of processing in order to create a consistent final product. One fundamental step in sugar processing is the use of a sugar dryer. Drying is traditionally achieved using high-grade equipment, typically a rotary dryer, in order to produce a consistent, quality product free of lumps and discoloration.

Storing sugar at the right sugar temperature and humidity is very important to avoid sugar caking. Therefore, the sugar temperature should be reduced to less than 6K above the temperature and the sugar moisture kept below 0.04 %. In many sugar mills the final temperature of sugar usually remains above 40 °C causing constant caking problems. In general, a lot of caked sugar is reprocessed which requires additional energy & efforts causing loss of revenues.

Hengyang rotary sugar dryer & cooler is designed for optimum sugar residence time and a drum diameter to preserve the final quality of a sugar curtain, which improves contact of sugar with the air flows, again improving the heat exchange efficiency. The breakage of crystals during the drying/cooling process in minimized.

Besides the traditional chain drive arrangement, Dryer plus alternatively comes with friction drives to reduce the annual maintenance cost as well as flexing and torsion of the drum body.
