  • 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 are the steps involved in shea butter extraction plant?
  • 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. The cleaning process can reduce equipment friction, ensure safe operation, reduce butter loss, improve life of wear parts, increase yield and improve butter and meal quality.
  • What are the 4 layers of a shea nut?
  • The fruit is composed of four layers - the epicarp, mesocarp, shell and the kernel. The epicarp together with the mesocarp is called the pulp; the shell and the kernel compose the nut. The kernel is the oil-bearing material that can be obtained by processing the shea nut fruit.
  • 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 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.
  • When are shea nuts ripe?
  • Fruiting and gathering of shea nuts occur between May and August each year. In this stage, shea nuts are processed into kernel form. Both raw and ripe fruits are green but ripe fruit is occasionally yellowish and soft when felt. The fruit is composed of four layers - the epicarp, mesocarp, shell and the kernel.
