Soybean processing for oil extraction and biodiesel
Solvent Extraction Hexane is extensively used for oil extraction from soybeans and other oilseeds because of its low vaporization temperature, high stability, low corrosiveness
Economic feasibility analysis of soybean oil production by hexane
Hexane extraction process Crop preparation (handling), solvent extraction, degumming, desolvenization, and meal processing are main processes of the soybean oil hexane extraction process (Fig. 1). Crop preparation includes oil seed cleaning, cracking, dehulling, conditioning, and flaking.
Green solvents and technologies for oil extraction from oilseeds
Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to
Replacing hexane by ethanol for soybean oil extraction: Modeling
The soybean oil extraction occurs through a countercurrent percolation system. The solvent moves into the soybean flakes pores and extracts the oil. The extraction unit has two output streams: the miscella, rich in oil and the meal, a solid fraction rich in protein.
Effect of feed particle size and solvent flow rate on soybean
J Food Sci Technol (December 2022) 59(12):4723–4730 47251 3 Extraction of soybean oil using modied Soxhlet apparatus Soxhlet apparatus consisted of 250 mL round bottom ask tted with butt type extraction tube and condenser.
Economic feasibility analysis of soybean oil production by hexane
The extraction efficiency using solvents is dependent on the solvents?ability to solubilize the oils and extract them from the seeds, extraction temperature and seed particle size (Abdul Hakim Shaah et al., 2021; Nde and Foncha, 2020). n-Hexane is the most commonly used solvent for plant-based oil extraction due to its high oil yield and low costs, and remains as the accepted method
An energy-friendly alternative in the large-scale production
Soybean oil is widely used as cooking oil, whereas the soybean cake is a valuable ingredient for animal food. The extraction of soybean oil is an energy-intensive process, with additional significant impact on the environment via the wastewater and hexane emissions. The research investigated differe
Replacing hexane by ethanol for soybean oil extraction: Modeling
The authors considered the soybean field, the crushing/extraction process (with hexane as solvent) and biodiesel synthesis. Their results showed that soybean crops are strongly dependent on chemical inputs and technology in order to obtain high yields. And the most energy demanding stages are soybean plantation and biodiesel production.
Processes Free Full-Text Extraction Methods of Oils
For example, a TEA model on soybean oil hexane extraction identified that a plant capacity of 34.6 million kg of annual soybean oil production was needed for the process to financially breakeven []. For the EAEP of soybean oil to be profitable, annual oil production could not fall below 8.5 million kg [ 70 ].
Recent advances in green soybean oil extraction: A review
Perspectives for using green solvents in soybean oil extraction. Disregarding the information about reuse, recovery, and technical-economical, which has a considerable lack of literature, the replacement of hexane in the industrial processes with a green solvent seems to be the best alternative for soybean oil extraction.
