The pressed cake/meal containing about 15% to 18% butter is then processed by Solvent Extraction to bring down residual oil content to less than 1.5%. This De-oiled cake with less than 1.5% residual butter is used as a fuel for combustion in a boiler for steam generation. This is another speciality of GOYUM Shea Butter Extraction Plant.

Oil processing equipments of oil mill plant

The special design of the expellers are with lower residual oil left in cake and make higher oil output; The quality of oil cake from pressing is higher, more suits for downstream processing. Versatile to process many kinds of oil seeds, such as peanut kernels, rapeseeds, cotton seeds, sunflower seeds, corn germ, palm kernel, sesame, etc.

relatively low yield of oil recovery. Even the most powerful presses cannot reduce the level of residual oil in the press-cake below 3 to 5%. In the case of oil-rich seeds such as sesame or peanuts this may still be acceptable. Furthermore, most of the oil left in the cake can be recovered by a stage of solvent extraction.

These steps detail the procedure for recovering the solvent from the oil using a rotary evaporator, further drying the oil to remove the residual solvent, and quantification of the oil to determine the yield and then storage.

Shea Butter Oil Extraction Machine, Oil Press Group

Then, the flaked cake (5 ~ 7kg for each flaked) was pressed for the first time (pressure 40 ~ 50mpa, temperature 60℃ ~ 70℃), and the residual oil of the virgin flaked cake was 28% ~ 32%. According to the above process requirements, the virgin cake was broken, tempered and repressed, and the residual oil of the repressed cake was 18% ~ 23%.

In fact, the residual oil rate is one of the Best indicator to judge whether an oil press expeller is good or not. However, a lot of people don't know what the residual oil rate is. Today we're going to take screw oil press machine as an example to explain the residual oil rate. Low Oil Residual Rate Oil Press Machines for Sales

  • 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.
  • Does shea nut cake contain fat?
  • About 23% of fat still remain in the shea nut cake after a successful extraction (Abdul–Mumeen, 2013) and it is considered grossly inefficient, yielding not more than 35% of the oil with the product quality often low (Ata, 1978; Olaniyan and Oje 2007b; Niess, 1983).
  • 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.
  • How to extract butter from shea kernels?
  • The IMC method involves the use of a low pressure manual screw press to extract butter from shea kernels. The study established an optimum extraction temperature of 60 • C and moisture content of 12% at which butter extraction efficiency was between 65.9% and 68.5%.
  • Does shea butter need solvent extraction?
  • For these reasons, solvent extraction is generally not preferred for shea butter extraction—especially in food and cosmetic markets where consumers seek natural, organic ingredients. What is shea oil? Traditional water extraction, mechanical expeller pressing, and solvent extraction yield shea butter.
  • Should hexane be used for shea butter extraction?
  • The choice of hexane over other solvents for shea butter extraction is also informed by several factors: the physical properties of the solvent, the fAbdul-Mumeen et al. commercial economics of the butter and the edibility of shea oil from the extraction (Abdul–Mumeen, 2013).
