EvapCare™-S Short Path Evaporator: Advanced Purification for High Molecular Weight Compounds

Introduction

Purifying compounds with high molecular weight or extreme heat sensitivity is a significant challenge in many industries, from chemicals and pharmaceuticals to food and cosmetics. Traditional evaporation methods often fall short, risking product degradation or insufficient separation. Sulzer’s EvapCare-S short path evaporator is engineered to overcome these challenges, offering a cutting-edge solution for advanced purification and high yields.

What Makes the Short Path Evaporator Unique?

The short path evaporator is designed specifically for substances that require gentle treatment and efficient separation. Its innovative design places a vertical condenser inside the wiped evaporation chamber, minimizing the distance between the heating and condensing surfaces. This unique setup enables evaporation at very low pressures—well below 1 mbar, and in special cases, down to 0.01 mbar.

Key Features

• Low Residence Time:The product spends minimal time on the heated surface, reducing the risk of thermal degradation and secondary reactions.

• No Liquid Hold-Up:The design prevents product retention, ensuring high purity and yield.

• Very Low Pressure Drop:Enables operation at ultra-low pressures, crucial for heat-sensitive and high-boiling-point components.

• Mechanical Film Creation:Like in wiped film evaporators, a rotor ensures a uniform and stable liquid film for optimal heat transfer.

  
  

Typical Applications

The short path evaporator is the preferred choice for:

• Evaporation of High Molecular Weight Organic Compounds (usually over 200 g/mol)

• Purification of Fats and Derivatives

• Concentration of Active Pharmaceutical Ingredients (APIs)

• Purification of Additives for Food Products and Cosmetics

• Removal of Residual Monomers after Polymerization

• Purification and Deodorization of Edible Oils

  
  

This versatility makes it invaluable for industries where product quality, purity, and gentle processing are non-negotiable.

How the Short Path Evaporator Supports Your Process

By operating under high vacuum with a minimized distance between heating and condensing surfaces, the short path evaporator allows for the gentle evaporation of even the most sensitive compounds.

This is essential for preserving color, aroma, and functional properties critical for food, fine chemicals, and pharmaceutical products.

Sulzer’s expertise ensures that each short path evaporator is tailored to your process requirements, with options for specialized rotor designs, GMP compliance, and flexible operation.
