introduction
Molecular distillation is an advanced liquid-liquid separation technology that operates under a high vacuum, allowing separation to occur at temperatures far lower than a substance's normal boiling point.
This technology utilizes the principle of the difference in the mean free path of molecular motion. The liquid mixture is heated on a heated surface, causing the lighter components to evaporate molecule by molecule. These vapor molecules then condense on a separate cooling surface, achieving effective separation.
Working Principle
Material enters the evaporator and is immediately spread into a thin film by rotor wiper blades. Heat from the heating source is transferred through the cylinder wall to the liquid film.
The liquid film undergoes evaporation, and the vapor enters the internal condenser, where it condenses back into liquid and is collected for discharge. The residual concentrate is collected from the bottom outlet.
Structure
The 0.5 m² four-stage molecular distillation unit consists of the following components:
One wiped film evaporator (first stage)
One to three short-path distillation units (subsequent stages)
A feeding unit
A vacuum system
A cooling system
A heating system
An electrical control unit
Features
Four-stage molecular distillation process, with an independent vacuum system for each stage.
The entire unit is constructed from SS304 or SS316 stainless steel, making it suitable for food-grade applications.
Excellent thermal insulation, including jacketed insulation for piping.
Capable of processing high-viscosity materials.
Customizable to meet local voltage requirements
A purely physical separation process.
Simple and user-friendly operation.
