Feb 06, 2008 The rotary dryer was modeled after a continuous industrial rotary dryer used for the production of molecular sieves; it represents a “slice” of the industrial rotary dryer near the end of the drying process. It was operated in batch mode with regard to the solids.
Vacuum Rotary / Paddle Dryers provide fast, uniform, low temperature drying of press cake, filter cake, and slurry type materials requiring agitation and recovery of solvents during drying. The batch drying time depends on the composition, nature and amount of solvent present in the wet product.
About 70 h of continuous drying was needed to complete the drying process at the overall thermal efficiency of 10%. Although the thermal efficiency is not that satisfactory, the dryer was found to be economical in comparison to other methods due to the quality of the final product and the ability to perform under adverse environmental conditions.
drying gas in either single or multi cyclones, and/or bag filters. Sometimes cyclones are followed by scrubbers for final cleaning of the exhaust gases. The Ring Dryer employs the same basic principle as the flash dryer in that the material to be dried is dispersed and conveyed through the dryer in a hot air stream. However the Ring Dryer
Rotary Vacuum Paddle Dryer (RVPD) is used to obtain dry prowder from a wet cake or solution. The drying is carried out in a batch process under vacuum, making this one of the most economical solution for drying. RVPDs are ideally suited for low temperature drying, solvent recovery, mixing, blending and extraction of useful liquids.

Rotary Wood Dryer Introduction Rotary wood dryer, a kind of traditional drying machinery, is widely applied in industrial manufacture. Especially, it is a good option to dry biomass materials with high moisture in wood pellet process.The rotary dryer machine provided by us is suitable for drying sawdust, wood shavings, wood chips, bagasse, alfalfa, straw and other materials.
The rotary sugar dryer . In a rotary sugar dryer, for instance, sugar is dried in countercurrent or co-current air flows, while tumbling through the rotating, cylindrical drums. Rotary drum dryers are not prone to stickiness or clumping. However, fine, low-weight sugar particles might be entrained with the gas or air that flows through the dryer.
