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.
How is shea butter extracted?
Extraction of shea butter from shea kernels can be done via either water extraction i.e. boiling with water, mechanical extraction, solvent extraction, or a combination of these processes. The traditional method of how shea butter is made involves water extraction – boiling the shea kernels with water and skimming off the released oils.
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.
How is shea butter made in Africa?
The shea tree is considered the second most important oil crop in Africa after the oil palm tree . Following de-pulping (for consumption or conservation), the dried shea kernels are processed into shea butter through grinding, roasting, milling, churning, washing, and heating (Figures 2 and 3) . … …
What is the shea butter export market?
The shea export market traditionally traded raw shea kernels rather than shea butter or other finished products. However, as shea applications have evolved and processing methods have improved, shea butter exports have increased as producing countries invest in more advanced equipment.
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.
