In citrus essential oil extraction, centrifuges are primarily used for the efficient separation of essential oils from the aqueous phase. Centrifugal force rapidly separates the oil-water mixture produced by pressing or distillation, significantly improving separation efficiency and essential oil purity.
The application process consists of two steps:
1. Pretreatment: The post-extraction "oil-water mixture" (containing essential oil, water, and a small amount of pulp residue) is filtered to remove solid impurities and prevent damage to the centrifuge's internal components.
2. Centrifugal Separation: The filtered mixture is fed into the centrifuge. The centrifugal force generated by high-speed rotation rapidly separates the essential oil (lower density) and water (higher density) into separate layers based on their density differences. The resulting pure essential oil layer and the recyclable aqueous phase are then collected.
Comparison of different types of centrifuge selection
Centrifuge Types | Core Advantages | Applicable Scenarios | Key Considerations |
Disc Centrifuge | 1. Extremely high separation efficiency, continuous feeding and discharging, suitable for large-scale industrial production; | Large-scale citrus essential oil processing plants, with daily processing capacity ranging from several to tens of tons, require continuous and efficient production (e.g., mass production of orange and lemon oils). | 1. The initial investment and maintenance costs are high. |
Tubular Centrifuge | 1. Extremely high speed (up to 15,000-20,000 rpm) and a large separation factor enable separation of oil-water mixtures with high viscosity or slightly emulsified content, resulting in higher purity essential oils; | 1. Small-scale production or laboratory research and development, such as small-batch trial production of new essential oils (e.g., blood orange and grapefruit oils); | 1. This is a batch operation with a small processing capacity, making it unsuitable for large-scale continuous production. |
Decanter Centrifuge | 1. Simultaneous solid-liquid separation and oil-water separation are possible, eliminating the need for separate filtration and deslagging, simplifying the process; | Small and medium-sized processing plants, where the post-extraction mixture contains high residue content (e.g., when using a screw press method with incomplete filtration), seek to simplify pretreatment steps. | 1. Separation accuracy is slightly lower than that of disc and tubular centrifuges, and secondary separation may be required to improve essential oil purity. |
