What is the difference between oil expeller & dehulled soybeans?
The oil extracted from the oil expeller machine is transported to an oil refinery, while the deoiled cake is processed for other applications, like use as animal feed. Meanwhile, the dehulled soybeans go through further cooking or conditioning, flaking and extrusion before they are ready for solvent extraction.
How to start a soybean oil manufacturing plant?
Investing in a plot of land as well as the construction costs of your facility will be the other significant chunk of your overall investment in the soybean oil manufacturing plant cost. Before you can begin production of any sort, you should ensure that you have all the necessary licenses and certifications associated with soybean oil production.
What equipment do you need for oil extraction?
Equipment will form one of the largest chunks of your investment. You will need a seed cleaner, a cooker and conditioner, a cracker or dehuller, an expander, and a flaker for your oilseed preparation. You will need an expeller press machine for mechanical extraction and an oil extractor machine for solvent extraction.
How is soybean oil extracted?
In the solvent extraction process, food-grade hexane is sprayed over the extruded soybean flakes, with counter-current flow leading to oil extraction and distillation allowing for the separation of solvent and oil. Again, the deoiled meal is also desolventized before it can be processed for other applications. How is soybean oil refined?
