Distillation is an ancient separation method that is still essential in modern industries such as chemical, food and pharmaceutical. While the core of the process remains the same, innovations such as vacuum technology provide vast improvements in efficiency, quality and energy consumption. But how does distilling under vacuum work, and what role do DOVAC’s vacuum systems play in this process? In this blog, we dive into the world of vacuum distillation.
What is distillation?
Distillation is a technique that separates components of a liquid mixture based on their boiling points. By heating the mixture, the substances with lower boiling points evaporate first, after which they are collected and condensed.
Traditional distillation:
- Based on atmospheric pressure.
- Requires high temperatures, which can lead to thermal damage to sensitive products.
Vacuum distillation:
In this process, the pressure in the system is reduced, allowing liquids to evaporate even at lower temperatures. This makes it ideal for processes involving heat-sensitive or complex molecules.
How does distillation under vacuum work?
In vacuum distillation, a vacuum pump is used to reduce the pressure in the system. This has several advantages:
- Lower boiling points: Reduced pressure requires less heat, which minimizes the risk of product degradation.
- Energy savings: The process requires less energy because the temperatures are lower.
- Higher purity: Impurities are separated more effectively, resulting in a better final product.
The main applications of vacuum distillation
Chemical Industry
Vacuum distillation is widely used to purify chemicals with precise specifications, such as solvents and oils.
Food Industry
When producing alcohol, essential oils or pure aromas, vacuum distillation is crucial to preserve flavor and quality.
Pharmaceutical Manufacturing
In pharmacy, drugs and active ingredients are often distilled under vacuum to ensure stability and efficacy.
