Whether in the form of cold-pressed oil for haute cuisine or as a raw material for cosmetics and pharmaceutical products, avocado oil is fashionable. The boom came at about the same time as the rapid growth of the olive oil market.
So GEA Westfalia Separator Group logically transferred its positive experience with the 2-phase system for olive oil to obtaining avocado oil. By adapting this technology, the conventional method of obtaining this oil using 3-phase decanters was supplemented by an even more economical variant.
Conventionally, the oil used to be obtained from the fruit of the avocado tree with the aid of 3-phase decanters. A key drawback was the relatively high consumption of water. The 2-phase system works in the decanter stage without the addition of water, achieving yields of 80 to 90 percent. The method of operation, which is gentle on the product, makes this process particularly suitable for the production of top-quality avocado oil obtained by the cold process.
Once the stones and skins have been removed, the avocados first pass to a disintegrator and then to a kneader. The 2-phase decanter separates the mass into deoiled fruit flesh and an oil phase. In a final step, extremely fine contamination is removed from the oil by a polishing separator so that top-quality clear avocado oil results.
The significantly lower water consumption and the associated reduced quantity of waste water make the 2-phase system a highly economical process, the potential of which is leading to wider and wider applications.
