“…No study similar to this one was found in the literatures. Mpagalile et al (2006) and Pighinelli et al (2008) evaluated the effect of moisture content of A. hypogaea L. and Helianthus annus L., respectively, in oil extraction by mechanical pressing through which the second author found the range of 8 to 8.5% that would be the maximum …”

The selection of species that accumulate oil with potential for biofuel production has favored advancements in the scientific and technological domains within the Brazilian biofuel program. The equipments and methods used for such selection have always prosecuted the objective of increasing oil extraction. The aim of this paper was to evaluate the yield of oil extracted from five vegetable species -castor oil plant (Ricinus communis), physic nut (Jatropha curcas), soybean (Glycine max), groundnut (Arachis hypogaea L.), and crambe (Crambe abyssinica) with two different moisture contents and using two different solvents, hexane and ethanol. The experimental design was factorial (5 × 2 × 2), in which grains of each of the five vegetable species in two different moisture contents were used for oil extraction. It can be concluded from this study that grain moisture content and solvent type had great influence in determining oil yield; and that hexane extraction was most efficient. J. curcas had the greatest increase of oil yield with 30.70% when performing extraction with grain moisture. The smallest differences between the solvents were found in the species R. communis with 12% of higher efficiency with hexane extraction.

“…These include solar stills, humidifi ers and dehumidifi ers, membrane distillers, reverse osmosis or electro-dialysis water desalinators (Mathioulakis et al, 2007), water pumps using solar PV and an AC or DC motor (Delgado-Torres and Garcia- Rodriguez, 2007), solar adsorption refrigerators (Lemmini and Errougani, 2007) and oilseed presses (Mpagalile et al, 2005). Various other forms of load management may also be important for balancing autonomous systems that feature signifi cant amounts of supply and demand variability.…”

“…The physical extraction by crushing in a screw is based on submitting the seeds to the intense mechanical action provided by conveyer screws turning within a fixed barrel (Dufaure et al, 1999). Optimization of the oil extraction process consists of defining the optimum parameters, for example, rotation speed of the screw, grain temperature and moisture content to reach the highest oil yields (Mpagalile et al, 2006). The advantage of this technology is the low installation cost and consequently small traders can use it to process their oilseeds.…”
