Extracting Oil From Shea-Nuts Equipment Ce in Egypt

How do you extract oil from shea nuts?
The milled Shea nuts (1600g) were extracted using hexane (2.5 litres) in a soxhlet apparatus (Konte USA) for 6 hours at 60°C. The oil was obtained after evaporating over water bath at 70 o C to remove excess solvent, dried in an oven and cooled in the desiccators and then re-weighed to determine the amount of oil extracted . … …
How is shea nut oil made?
The process of making Shea Nut Oil is similar to the production process of other fractionated carrier oils. The raw Shea Butter pressed from the Shea nut undergoes a process known as fractionation, which allows its liquid oil (the ‘olein’) to separate from the heavier components (the ‘stearin’).
What is the mechanical press method of shea butter extraction?
The mechanical press method of shea butter extraction has been reported by FAO and CFC (2002) but one of the earliest research on the use of the mechanical press was by Marchand (1988). His research revealed that equipped with a jack that exerts 30 tonnes of force, a shea butter press could crush more than 3 kg of shea kernels within 20 minutes.
How is shea butter extracted?
The fruit primarily undergoes several processes – de-pulping, boiling, drying, deshelling, winnowing and sorting – to obtain the kernel from which the shea butter is extracted. Mechanical processing technology referred to as the Cold Press Extraction method, does not involve the various different heating stages involved in traditional processing.
