“…Table 5 lists the oil content of residual meal extracted from camelina and canola seeds at 15 Hz. The solvent extraction method was capable of recovering about 99% oil contained in the oilseeds [34]. In this study, the oil content of residual meals was defined as the measured oil content of residual meals using solvent extraction method divided by 99%.…”

Bio-jet fuel produced from non-edible oilseeds can be an alternative to fossil fuels with the benefits of increasing national energy security, reducing environmental impact, and fostering rural economic growth. Efficient oil extraction from oilseeds is critical for economic production of bio-jet fuels. Oil extractions from camelina (sativa) and canola (Brassica napus) seeds were conducted using a cold press method. The effect of the frequency controlling the screw rotation speed on the oil recovery and quality was discussed. Characterization of the produced raw vegetable oils, such as heating value, elemental content and main chemical compositions, was carried out. The results showed that the oil recovery increased when the frequency decreased. The highest oil recoveries for camelina and canola seeds were 88.2% and 84.1% respectively, both at 15 Hz. The cold press frequency and processing temperature (97.2˚C -106.0˚C) had a minor influence on the qualities and recovery of both camelina and canola oils. In addition, camelina and canola oils produced at 15 Hz underwent catalytic cracking to examine potential hydrocarbon fuels production. It was observed that some of oil physicochemical properties were improved after catalytic cracking. Although more study is needed for further improvement of oil recovery and qualities, cold press could be an efficient method for oil extraction from non-edible oilseeds. Additionally, the preliminary results of upgrading the oils produced show very promising for future bio-jet fuels production.

“…However, the use of such a technology appears promising, even if the equipment and maintenance costs must be carefully considered. For the moment, mechanical oil extraction from jatropha seeds is generally carried out using a hydraulic press (Tambunan et al, 2012) or a single expeller press (Karaj and Müller, 2011;Pradhan et al, 2011;Ofori-Boateng et al, 2012). Similarly, oil extraction efficiency is quite promising using a Komet D85-1G (Germany) mechanical screw press (Karaj and Müller, 2011).…”

“…As principais tecnologias utilizadas atualmente para extração de óleos vegetais pela maioria das indústrias são a extração mecânica e a extração por solventes, principalmente em função de seu baixo custo, eficiência e simplicidade em comparação com outras técnicas (OFORI-BOATENG et al, 2012).…”

O principal objetivo deste estudo foi gerar tecnologias para a extração de óleo de pinhão manso, avaliando a quantidade e qualidade com diferentes métodos de extração. Para a extração do óleo foram utilizados dois tipos de extratores (fator A), prensa tipo expeller e prensa hidráulica, temperatura (fator B) frio (ambiente) e quente (80ºC) e diferentes níveis de descascado das sementes (fator C). Foi utilizado um delineamento inteiramente casualizado com arranjo fatorial AxBxC. As variáveis estudadas foram: quantidade e qualidade (acidez, teor de fósforo e umidade), do óleo bruto e filtrado, e a quantidade de torta. A prensa tipo expeller apresentou as maiores médias de desempenho de óleo bruto. A partir de três kg de sementes com 40% de descascado foi obtido 37,18% de óleo bruto. No índice de acidez, as menores médias foram observadas por prensa hidráulica, com 0% de cascas, com 4,11 mg KOH/g na acidez do óleo bruto e 5,17 mg KOH/g na acidez do óleo filtrado. Foram obtidos menores teores de fósforo, usando prensa hidráulica sem pré-aquecimento, com valores de 72,53 ppm no óleo bruto e 10,32 ppm no óleo filtrado. Foi alcançado maior teor de óleo com a prensa tipo expeller, mas de melhor qualidade na prensa hidráulica.Palavras Chave: bioenergia, biodiesel, teor de óleo.
