STRIPPER MACHINE

Stripper Machine for CMC Production

A Stripper Machine is a key processing unit in modern Sodium Carboxymethyl Cellulose (CMC) and Polyanionic Cellulose (PAC) production, designed to efficiently separate solvent, impurities, and by-products from CMC slurry after the etherification reaction. Its role is critical in ensuring product purity, improving yield, and enhancing overall production stability.

Working Principle

During CMC production, the stripper machine uses controlled heating, vacuum, and mechanical agitation to remove reaction solvents such as isopropanol (IPA) and other volatiles from the wet CMC mixture. This step helps break up lumps, promotes uniform material flow, and prepares the CMC for downstream washing and drying.

Key Features & Benefits

• High Efficiency Solvent Removal
  Ensures thorough stripping of IPA and reaction residues, contributing to clean and stable product quality.

• Improved Product Consistency
  Helps achieve uniform viscosity and DS (Degree of Substitution) distribution.

• Energy-Saving Design
  Optimized heat transfer and mechanical structure reduce energy consumption during solvent recovery.

• Robust Construction
  Made with corrosion-resistant materials suitable for alkaline environments, ensuring long service life.

• Customizable for Different Grades
  Available in capacities and configurations tailored for industrial grade, detergent grade, food grade, and oil drilling grade CMC production.

Applications

The stripper machine is widely used in CMC plants for:

• Solvent removal after etherification

• Slurry conditioning before washing and separation

• Enhancing both high-viscosity and low-viscosity CMC production lines

• Ensuring cleaner final products for industries such as food, oil drilling, ceramics, textiles, and paper making
