As a common ingredient, garlic is not only rich in nutritional value, but also has multiple health benefits due to the garlic oil it contains. Garlic oil is a volatile oily liquid extracted from garlic, which mainly contains sulfide, alliin, alliin and other components, and has a strong garlic odor and spicy taste. In order to extract garlic oil from garlic efficiently and accurately, centrifugal extractor, as an advanced separation technology, has been widely used.

Introduction to garlic oil

Garlic oil is a volatile oily liquid extracted from garlic bulbs and has a strong garlic and pungent taste. Garlic oil mainly contains sulfide, alliin, alliin enzyme, a variety of amino acids, vitamins, trace elements and other components. These ingredients make garlic oil have a wide range of biological activities, such as antibacterial, anti-inflammatory, antioxidant, anti-tumor, etc. Therefore, garlic oil has a wide range of application prospects in food, health products, medicine and other fields.

Working principle of centrifugal extractor

Centrifugal extractor is a device that uses centrifugal force to accelerate the liquid-liquid extraction process. It uses the centrifugal force generated by rotation to separate the different components of the mixture according to density differences. When the mixture is placed in the centrifugal cup of the rotating centrifuge, the action of centrifugal force causes the denser material to move toward the outside of the centrifugal cup and the less dense material to move toward the center of the centrifugal cup. In this way, the matter is effectively separated. By controlling the rotation speed and centrifugal time of the centrifuge, the separation of the target material from other impurities can be precisely achieved.

Application of centrifugal extractor in garlic oil extraction

Raw material preparation:

Select fresh, good quality garlic as raw materials, peel, wash and chop to increase the contact area between garlic oil and solvent and improve extraction efficiency.

Solvent selection:

According to the dissolution characteristics of garlic oil, the appropriate solvent was selected for extraction. Garlic oil is slightly soluble in water, but soluble in ethanol, benzene, ether and other organic solvents. When choosing a solvent, consider its solubility, safety and convenience of subsequent treatment.

Mixing and stirring:

The chopped garlic is mixed with the selected solvent in a certain proportion, and fully stirred or soaked for a period of time under the appropriate conditions, so that the garlic oil can be fully dissolved into the solvent.

Centrifugal extraction:

The mixture is placed in a centrifugal extracter, which generates a strong centrifugal force through high-speed rotation, prompting the different components of the liquid to stratify according to density differences. The garlic oil dissolved in the solvent forms a solution that separates from the solid residue under centrifugal force.

Collection and purification:

After centrifugation is complete, the supernatant (i.e. the solvent containing garlic oil) is carefully removed and the garlic oil is further purified and collected by distillation, concentration and other methods.

Solvent recovery:

For the remaining solvent, it can be recycled through distillation and other ways, which both saves cost and is conducive to environmental protection.

Advantages of centrifugal extractor

High efficiency separation: The centrifugal extractor can quickly separate garlic oil from other impurities to improve extraction efficiency.

Strong controllability: By adjusting the rotation speed and centrifugal time of the centrifuge, the extraction process can be precisely controlled to ensure the purity of garlic oil.

Environmentally friendly: The centrifugal extraction process does not need to use a large number of chemical reagents, reducing environmental pollution.

Wide range of application: centrifugal extractor is not only suitable for laboratory scale garlic oil extraction, but also for large-scale extraction in industrial production.

Matters needing attention

In the actual operation process, the following points should also be noted:

Raw material selection: Ensure the selection of fresh and good quality garlic as raw materials to improve extraction efficiency and the quality of garlic oil.

Solvent selection: Choose a solvent that is good for garlic oil solubility, high safety and easy to recover.

Temperature control: Avoid operating under high temperature conditions to prevent oxidative degradation of garlic oil.

Safety: Follow the relevant safety operation procedures to ensure the safety of operators.

Centrifugal extractor, as an advanced separation technology, has significant advantages in the extraction process of garlic oil. Its characteristics of high efficiency, controllability and environmental protection make the extraction of garlic oil more efficient and accurate. With the continuous progress of technology and the deepening of application, centrifugal extractor will play a greater role in the extraction of garlic oil, providing more possibilities for food, health products, medicine and other industries.
