1. Overview and Extraction Principle
We define an aromatic oil extraction tank as a refining equipment used to recover aromatic oil substances. Its extraction principle is clear and straightforward, with specific steps as follows:
First, we add the extraction solvent and plant materials containing aromatic oils to the tank according to a specified technological ratio. Next, we use the jacket to heat the mixture inside the tank.
Once the mixture reaches the evaporation temperature, we adjust the input of jacket steam. This adjustment maintains the internal temperature for a set period, as required by the process.
As the heating proceeds, the aromatic oils volatilize into vapor. We then use a cooling system to cool this vapor. Finally, we use an oil-water separator to separate the cooled material into oil and water.
2. Key Characteristics and Plant Distribution of Aromatic Oils
The aromatic oil extraction tank features simple operation, reliable technology, and high extraction efficiency. Aromatic oils predominantly exist in plants, with their distribution concentrated in specific parts.
Generally, we can find them in petals, leaves, or tree trunks of plants. Although the extraction processes for different plant parts are largely similar, significant differences exist in oil content and extraction yield.
3. Tank Material and Structural Design
We fabricate the main body of the aromatic oil extraction tank from high-quality non-toxic and clean 304 stainless steel. For all other parts that do not come into contact with materials, we adopt specified materials as required.
We design the sections in contact with the liquid medicine without any dead corners. Additionally, we smoothly treat the surface of these sections to prevent material accumulation and facilitate easy cleaning.
We also design the equipment structure rationally to meet process requirements. This rational design also allows for easy cleaning, reducing maintenance workload.
4. Process Nozzles and Cleaning Configuration
We equip the extraction tank with various process nozzles to meet different operational needs. These nozzles include CIP (Clean-In-Place) ports, drinking water ports, steam ports, and condensate water ports.
We also install nozzles for a thermometer, pressure gauge, liquid outlet, circulation, liquid inlet, and reflux. Furthermore, we fit the tank with a cleaning ball to enable convenient online cleaning, ensuring hygiene standards are met.
5. Filtration System
5.1 Bottom Filtration
We adopt a bottom filtration design for the tank, which provides a large filtration area. This design enhances filtration efficiency and ensures thorough solid-liquid separation.
5.2 Filter Mesh
We manufacture the filter mesh to be firm and strong enough to resist damage. We also design it to be detachable, making it easy to clean after use.
This detachable and durable mesh effectively achieves solid-liquid separation, ensuring the purity of the extracted aromatic oil.
6. Auxiliary Equipment
We configure the aromatic oil extraction tank with a full set of auxiliary equipment to improve extraction efficiency and operational convenience. Each auxiliary device has a specific function, as follows:
First, the foam catcher: we design it to efficiently capture material foam, preventing overflow during extraction. It also features easy-cleaning properties to save maintenance time.
Second, the condenser: we use it to effectively condense the liquid medicine vapor into a liquid state. We also design it for convenient cleaning to ensure long-term stable operation.
Third, the cooler: it is easy to clean, and we use it to cool the condensed liquid medicine to below 30°C. This low temperature optimizes the subsequent oil-water separation process.
Fourth, the oil-water separator: we use it to facilitate efficient separation of oil and water from the cooled liquid medicine. It is also equipped with a protective structure to prevent the medicine from flowing into the recovered volatile oil.
Fifth, the filter: it enables continuous operation of the equipment. It also avoids liquid outlet blockage caused by residue accumulation and is easy to disassemble and clean.
7. Heating System
We equip the extraction tank with a multi-section jacket and a central heating drum. This dual heating design allows us to heat the tank simultaneously or independently, depending on process needs.
Moreover, this design ensures the liquid medicine remains in a gentle boiling state, preventing violent boiling that could damage the materials. It also achieves excellent heating efficiency, reducing energy consumption.
8. Electrical Protection
We seal the electrical components of the equipment to prevent water erosion. This sealing design ensures the equipment operates safely and reliably, avoiding electrical faults caused by moisture.
