Embodiment Construction

[0062] According to the present disclosure, crushing under a pressure-controlled atmosphere is used instead of the traditional crushing step. Additionally, the traditional mixing step can be replaced with vacuum mixing to provide the treated raw material in the form of a paste. The oily raw material may be exposed to a vacuum in a vacuum vessel, also known as a vacuum extractor, which applies a vacuum to extract water from the oily raw material by evaporation or boiling.

[0063] In this application, the so-called oleaginous raw materials refer to biological raw materials including oil-containing and water-containing cells. According to one embodiment, the oleaginous raw material may be of animal origin, ie comprising animal cells. According to another embodiment, the oleaginous raw material is plant-based, including for example oily fruits, grains, seeds, nuts and legumes. Examples of suitable plant-based raw materials include, but are not limited to, olives, avocados, palm...

Abstract

The present invention relates to a method and system of extracting an oil from an oil- containing raw material comprising the steps of providing a non-crushed oil-containing raw material, and treating the non-crushed oil-containing raw material. The treatment is performed by exposing the oil-containing raw material to vacuum, wherein the vacuum defines an absolute pressure of between 1 mm Hg and 150 mm Hg, and a temperature of between 0 DEG C and 45 DEG C, and by subjecting the oil-containing raw material to crushing, simultaneously and / or subsequently to the step of exposing the oil-containing raw material to the vacuum, to provide a treated oil-containing raw material. By the method and system, high yield of oil with high quality can be obtained.

Description

technical field [0001] The present disclosure relates to a method of processing an oleaginous raw material and a system for processing an oleaginous raw material as defined in the appended claims. Background technique [0002] The process of producing oil from oily fruits by physical means is well known, and current technology is based on principles similar to those used for centuries. However, a lot of manual work is replaced by machines, which reduce labor costs and time. One of the major changes in the production process of olive oil, or any other oil from oily fruits, is caused by the introduction of a method that uses centrifugal force to separate the oil from the pulp (also known as the paste) after blending. The use of centrifuges for the separation step makes it possible to produce oil using a continuous system. [0003] The traditional oil production process includes the steps of delimbing, defoliating and washing the raw material (i.e. freshly harvested oily frui...
