Steam Stripping Dryer for CMC Production | CMC Steam Stripping Dryer
The Steam Stripping Dryer, also known as a Stripper Dryer, is a key solvent removal equipment used in modern CMC and PAC production lines, designed for efficient IPA stripping, solvent recovery, and stable downstream processing after the etherification reaction.
It plays a critical role in improving product purity, production yield, and overall process stability in industrial CMC manufacturing.
Function & Role in CMC Production Line
In a typical CMC production process, the stripping dryer is installed after etherification and before washing and final drying.
Its main functions include:
Removal of reaction solvents such as isopropanol (IPA)
Reduction of residual alkali and volatile impurities
Conditioning of CMC slurry for stable washing and separation
Improving yield and consistency of final CMC products
This step is essential for both high-viscosity and low-viscosity CMC production lines.
During CMC production, the steam stripping dryer operates through a combination of:
Controlled heating (steam or thermal medium)
Vacuum system
Mechanical agitation
to continuously strip IPA and other volatile solvents from the wet CMC mixture.
This process helps to:
Break up agglomerates
Improve slurry fluidity
Enhance mass transfer efficiency
Prepare the material for downstream washing, centrifugation, and drying
The design ensures stable operation, efficient solvent recovery, and consistent product quality.
Key Features & Benefits
