steam distillation apparatus for essential oils

Product Introduction

Steam distillation essential oils is a traditional method that uses water vapor to remove volatile components from plants and then condenses and separates them to obtain essential oils. It is particularly suitable for natural aromatic substances that are insoluble in water, have a high boiling point, or are easily decomposed when heated.

The steam distillation apparatus for essential oils is the most commonly used, low-cost, and mature technical solution for extracting thermosensitive plant essential oils in laboratories and small-scale production. The mainstream equipment capacity covers 20L – 1000L/batch, and the material is mainly SUS304/316 stainless steel. It has been widely used in dozens of aromatic plants such as roses, rosemary, and thyme.,etc

Product Advantage
1. Efficient extraction of active ingredients
By steam permeating plant tissues, volatile essential oils are released, preserving natural aroma and pharmacological activity.
Compared to solvent methods, there are no chemical residues and it meets food/drug safety standards.
2. Energy saving and compact design
The indirect heating system for heat conduction oil quickly heats up to 100 ° C with low energy consumption.
The 150L batch equipment only occupies 1.5 square meters and is suitable for small laboratories or factories.
3. Intelligent control and stability
The digital temperature control system monitors the distillation temperature in real time to avoid overheating and damaging the essential oil components.
Three layer stainless steel structure (SUS304/316) is corrosion-resistant and has a long service life.
4. Multi functional applicability
Compatible with various raw materials such as flowers, herbs, resins, etc. (such as lavender, rosemary, citrus).
Expandable vacuum distillation module for processing thermosensitive substances

Equipment structure and features
Steam generator; Pumpkin shaped design (non-traditional round bottom flask) enhances steam production efficiency.
Distillation tower: triple tube structure: inner tube for steam, middle layer for heating gas, outer layer for condensation reflux.
Condensation system: coil type water cooling design, efficient separation of essential oils and moisture.
Oil water separator; Using density differences to automatically stratify, essential oil collection purity>99%.
Intelligent control panel: adjusts temperature/pressure/time parameters, supports automated batch production

principle
steam distillation apparatus for essential oils  is introduced into the raw materials to lower the boiling point of essential oils, causing them to evaporate below 100 ° C.
Steam and essential oil azeotropic → condensation → oil-water separation → collection of pure essential oil.
Standardized process
