A wiped film evaporator (WFE) is used for various processes including concentration, distillation, stripping, dehydration, and deodorization.
These processes are particularly beneficial for heat-sensitive or viscous products.
Industries that commonly use wiped film evaporators include chemical, food and beverage, pharmaceutical, biotechnology, and nuclear sectors.
4 Key Applications and Benefits of Wiped Film Evaporators
1. Enhanced Manufacturing Efficiency
The wiped film distillation process helps manufacturers by reducing operating temperatures and pressures.
This reduction increases evaporation rates and shortens residence time.
These improvements allow for fine separations and low-temperature distillations to be performed.
2. How a Wiped Film Evaporator Works
A wiped film evaporator operates with three main parts: a feed inlet, rotor blades, and outlets for product concentrate and vapor.
The feed is introduced at the top of the device.
The rotor blades distribute the liquid to create a thin film on the evaporative surface.
This thin film maximizes surface area and heat transfer, facilitating efficient evaporation.
3. Industry-Specific Applications
Wiped film evaporators are prevalent in industries that require devolatilization, purification, and stripping of raw liquids.
For example, in the cannabis industry, it is used to separate residual waxes, fats, terpenes, chlorophyll, and plant materials from cannabidiol.
4. Differences Between Wiped Film Evaporators and Short-Path Distillation
Firstly, the condenser in a wiped film evaporator is placed outside of the heated evaporator surface.
In contrast, in short-path distillation, the condenser is placed inside the evaporator body.
Secondly, the wiped film evaporator creates a consistent thin film of material along the evaporative surface, maximizing surface area and heat transfer.
Short-path distillation involves the heating of a raw material on a heated tube's internal surface until the boiling component begins to evaporate.
Lastly, the applications of short-path distillation and wiped film evaporators may differ based on their design details.
