The industrial process of solvent extraction of castor oil
Castor meal is the main by-product of the industrial oil extraction of castor seed (Ricinus communis L.). It was observed that castor meal could be separated by sieving into apparently distinct

The industrial process of solvent extraction of castor oil
Periodically, the oil-rich filtrate is removed and mixed with the castor cake in order to extract the remaining oil in the step of solvent extraction. The cake enters another extruder and is subjected to heat, shear stress, and high pressure followed by quick decompression (expansion) in order to increase its porosity.

Production of Biodiesel from Castor Oil: A Review
Figure 2 shows a general scheme for castor oil extraction. To perform mechanical oil extraction from castor beans it is necessary to consider the high oil viscosity. On the contrary, this is not necessary if the oil is extracted with solvents, but an evaporation step would be needed to recover the solvent.

Castor Oil: Properties, Uses, and Optimization of Processing
Castor oil seed contains about 30%–50% oil (m/m). 74, 75 Castor oil can be extracted from castor beans by either mechanical pressing, solvent extraction, or a combination of pressing and extraction. 74 After harvesting, the seeds are allowed to dry so that the seed hull will split open, releasing the seed inside. The extraction process begins

Liquid-liquid equilibria of water + ethanol + castor oil
Offeman et al. [5] investigated a variety of vegetable oils such as castor oil, coconut oil, olive oil, and safflower oil to extract ethanol from an initial aqueous ethanol concentration of 5 wt%. Plant based oils used as solvents for liquid–liquid extraction of ethanol have shown high distribution coefficients and separation factors [5].

The industrial process of solvent extraction of castor oil
Castor seed entering in the industry has approximately 48% of oil content (Severino et al., 2015), and the castor cake sampled just after the expeller press had the oil content reduced to 10.96% ± 1.93 (Table 2). The extraction with solvent reduced the oil content of the wet castor meal to 1.71% ± 0.57 (Table 2).

How castor oil is
Castor oil is made from the seeds of the Ricinus communis plant through a process called extraction. The seeds, also known as castor beans, are harvested, cleaned, and dried. The oil is then extracted by either pressing or solvent extraction methods. The extracted oil is refined to remove impurities and improve its quality.

Optimization of Process Parameters for Castor Oil Production
Cold-pressed castor oil has low acid and iodine values, a slightly higher saponification value compared to that extracted using solvent extraction as well as being lighter in colour [3]. In literature, various attempts were made to optimize castor oil recovery. The optimum results were a recovery and moisture content of 48.75% and 5.8%

Enhanced castor seed oil extraction assisted by the
Castor oil extraction is performed using mainly two techniques: the crushing of seeds (hydraulic press or expeller-based techniques) and solvent extraction. The most commonly used solvent for the solvent extraction technique is hexane; however, hexane (non-polar solvent) is not an effective extractor due to the difference in polarity with some

Kinetic and Thermodynamics studies for Castor Oil Extraction
There are many extraction methods for obtaining the oil from the castor seeds. The extraction of oil from the castor seeds could be carried out in one step or combination of multi steps, such as mechanical pressing and solvent extraction18）. The examples of the mechanical pressing were hydrate presses and continuous screw presses.
