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 a shea nut Kettle?
The kettle uses steam for indirectly heating the Shea nut kernel. The kettle is specially designed to achieve a temperature of minimum 110°C at the outlet with a retention time of minimum 60 minutes. Coagulate the protein in the meal to facilitate separation of the oil from protein.
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 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.
