Comparison of oil press for jatropha oil - a review

Abstract

Siregar A.N., Ghani J.A., Haron C.H.C., Rizal M., Yaakob Z., Kamarudin S.K. (2015): Comparison of oil press for jatropha oil -a review. Res. Agr. Eng., 61: 1-13.As petrol will soon be exhausted in the near future, Jatropha is going to be one of the substitute candidates for future biodiesel production. Countries of South-East Asia, such as Malaysia, they are going to start the establishment of Jatropha plantations assuming that Jatropha will be the main resource for biodiesel production. A press is commonly used to extract oils from Jatropha. An oil press can be manually driven or engine-powered. In this paper, we will review some available advances focused on mechanical extraction techniques, covering three types of press for Jatropha oil extraction. We have found that major points like operating principles, oil extraction levels, advantages and disadvantages of each press and important factors to increase oil recovery. Based on the study, three types of press are: ram press, which is ineffective; strainer press, which is able to produce more oil than others and cylinder-hole press, which is the best due to its capacity in extracting oil from Jatropha seeds for about 89.4% of oil yields.

Screw press extraction of Sacha inchi seeds: Oil yield and its chemical composition and antioxidant properties

“…The mechanical pressing method of oil extraction from seeds has received much interest (Achten et al, ; Subroto, Manurung, Heeres, & Broekhuis, ). There are several advantages of using mechanical extraction compared to other methods, such as simple equipment, ease of operation, low investment, and low operating cost, as well as the absence of solvent in the oil product (Siregar et al, ). However, various operating conditions including pretreatment of the Sacha inchi seeds, extraction pressure, press head temperature, and storage condition affect the quality and quantity of the obtained oil.…”

Supercritical CO2 extraction of oil from Jatropha curcas: An experimental and modelling study

“…As a consequence, JC seeds represent an encouraging source of oil from which biodiesel may be derived by transesterification [3][4][5][6][8][9][10][11][12][13][14][15][16]. JC oil can be extracted by different methods, however mechanical extraction methods [15,[17][18][19] are generally preferred because the operational costs are low and they can easily be carried out by semi-skilled operators. Furthermore, the residue can be used for biogas production.…”

“…Using a cylinder-hole oil press (an expeller) with a twin-screw rotating core, it is possible to extract about 90% of the oil content of the seed, by weight. However, this is an upper limit, while a value of 80% seems to be a better practical average (Siregar et al, 2015). This percentage is called the oil extraction efficiency.…”
