  • How to process shea nut kernels?
  • For processing Shea nut kernels, we need a combination of mechanical pressing unit ( Oil Mill ) and solvent extraction plant (SEP). The following are steps involved in Shea Butter Extraction Plant : Shea nut kernels are separated and cleaned to remove impurities such as dust, metal, plant stalks.
  • 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 researches works on the use of the mechanical press was 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 min.
  • Is shea nut cake a waste product from shea butter processing?
  • Biochemical and microbiological analysis of shea nut cake: A waste product from shea butter processing. Thesis submitted to the Department of Biochemistry and Biotechnology in partial fulfilment for the award of Master of Philosophy in Biochemistry. Kwame Nkrumah University of Science and Technology, Kumasi, Ghana.
  • How is shea butter extracted in Ghana?
  • Extraction of shea butter is a major income generating activity in Ghana, particularly in the Northern Regions. It is estimated that about 80% of the shea butter produced in Ghana is processed by women using traditional aqueous extraction method. Commercial extraction using continuous screw press accounts for about 20% of production.
  • How is canola oil pressed?
  • In Mechanical Press, Canola oilseeds are pressed in a series of Screw Presses / Expellers. The mechanical process uses no chemical and leaves about 15-18 % residual butter in the pressed Cake/Meal. This cake is then cooled down in a meal cooler before being subjected to Solvent Extraction for further Extraction of Shea Butter.
  • What is a mechanical extraction press?
  • The mechanical extraction press principle involves separating the oil, water, and shea nut cake from pre-prepared water–paste emulsion shown in Fig. 5. The extraction machine encompasses a movable unit driven by a motor/engine. The separated entities (oil, water, and cake) occur in layers and according to their mass.
