from 2024%. Solvent extraction of the oil from the prepressed meal can reduce the residual oil content in the meal to less than 1%. Several factors can affect the efficiency of the solvent extraction process such as the type of solvent used, extraction temperature, solventtomeal ratio and the number of extraction stages. In order to achieve ...

Compared to distillation, extraction processes have the disadvantage that a new component is added to the system. This leads to additional impurities as complete immiscibility does only exist in theory. Furthermore a subsequent separation process is required to regenerate the solvent. However, there are a number of situations in which extraction is advantageous and they are summarized in the ...

Prepress/solvent extraction processes are, therefore, not applied to soybeans. It will be recalled from Chapter 1, that in the case of soybeans, the commercial value of the meal is usually higher than the income from sales of the corresponding quantity of oil. The quality of the meal is therefore a factor of particular importance in the selection of a processing method for soybeans. In this ...

solventsolvent extractions in general. A requirement of a solventsolvent extraction is that the two solvents be mostly insoluble in one another. That is, a mixture of the two solvents will separate into two layers. It is important to note that the upper layer is that which is less dense. For example, a mixture of tertbutyl methyl ether and water will separate into two layers, with the ether ...
