Part One: Introduction to the Extraction Unit for Essential Oils from Natural Aromatic Plants

For example: The distillation pot has a total volume of 1.5 cubic meters, and the essential oil and floral water extraction equipment requires approximately 200 to 300 jin of raw materials per batch.
1. Equipment Parameters
This production line equipment consists of a distillation kettle, a rectification unit, primary and secondary condensers, a re-distillation system, an oil-water separator, an aroma extraction unit, an alcohol-accelerating and deodorizing unit, a viewing window equipped with a wiper, temperature and flow control valves, a stainless steel operating platform, a stainless steel non-slip ladder complete with anti-slip steps, a stainless steel process safety fence, RO reverse osmosis purified water, and a steam generator.
This device combines jacket heating of the distillation kettle with direct heating via pure copper steam pipes to purify water by distillation. The distillation kettle is made of high-quality SUS304 stainless steel that comes into contact with the material, while the internal steam coil consists of copper tubes and pure copper sieve plates.
1. Structural Design: The equipment consists of a distillation kettle, a condenser, an oil-water separator, and an essential oil separation buffer tank. Both the interior and exterior surfaces of the equipment are polished to eliminate sanitary dead corners and meet GMP requirements.
2. Distillation kettle: Effective working volume: 1000 L; it employs direct steam heating and jacket heating.
Inside the vessel: Working pressure: atmospheric; Design temperature: 110℃; Operating temperature: approximately ≤100℃. Working medium: water. Pneumatic automatic slag-discharge door: diameter 800mm.
3. Demister Filter: The filter has a diameter of Φ150mm and is a pipeline-flow type, featuring a flush-mounted installation. The demister is easy to clean and complies with GMP requirements.
4. Condensing tower: Horizontal or vertical condensation.
Pressure vessel: Design pressure: Atmospheric pressure; Operating pressure: Atmospheric pressure; Design temperature: 100℃; Operating temperature ≤ 45℃. Working medium: Secondary steam. Material: S30408.
Shell side: Design pressure: 0.3 MPa; operating pressure: atmospheric pressure; design temperature: 100℃; operating temperature: around 35℃. Working medium: cooling water. Shell-side shell body: δ = 3 mm / S30408.
5. Oil-water separator: SUS304 stainless steel tank body, glass sight glass, and dedicated oil-water separator. The tank volume is 80L, with a cylinder wall thickness of δ=3mm/S30408. Sealed piping for oil collection, sight glass for oil monitoring, and condensate collection piping.
 

The equipment occupies an area of 2m × 3m × 4.5m per unit.

Part Two: Current Status of Essential Oil Extraction Equipment in the International Market
2.1 Overseas: Essential oil extraction equipment from Europe, Southeast Asia, and South Asia:

2.2、Domestic essential oil extraction equipment:

2.3 Conclusion:
Whether they are overseas or domestic essential oil companies, the equipment currently in use is all of the traditional, outdated distillation type. The shortcomings of this equipment are:

1. The kettle is made of thin material, resulting in poor steam circulation and unstable heat retention during heating. Its appearance is rough and unattractive, with dead corners that are difficult to clean and prone to secondary contamination. Moreover, the improper heating process affects both the oil yield and the quality of the extracted oil.
2. The proportions of pipe and certain accessory models, as well as the process steps, are incorrect.
3. The condenser’s heat transfer area and structure are incorrect.
4. The essential oil extract is impure, lacks sufficient clarity, and contains excessive impurities.
4. The oil-water separator is too small.
5. The oil yield expected from aromatic plants was not achieved.
6. Without fully enclosed material collection and effective filtration control, plant fibers and impurities in the hydrosol and essential oil will accelerate microbial growth and spoilage. During the subsequent settling and maturation of the essence, this accelerated microbial growth will further lead to product deterioration, off-flavors, and a reduction in the natural aromatic scent.

Part 3: Improved Natural Aromatic Plant Extraction Equipment: (Shengcai Equipment)

Oil extraction efficiency of the Shengcai extraction equipment:

Conclusion: The improved equipment boasts energy efficiency, high productivity, and an aesthetically pleasing, sophisticated appearance. It achieves the highest oil yield for the same batch of materials, producing oil that is crystal-clear and exceptionally pure. Compared to traditional distillation methods, this equipment significantly boosts both oil yield and the quality of the resulting essence. Overall, it offers substantial energy savings, high efficiency, and stable product quality. Fully aligning with the spirit of the 15th Five-Year Plan, we are phasing out outdated equipment and introducing new, technologically advanced, and continuously innovative machinery—creating superior products under the brand name Shengcai Zao.
