Cooking oil solvent extraction machine

Removing solvent traces

5 .

Ninety percent of the solvent remaining in the extracted oil simply evaporates, and, as it does, it is collected for reuse.

The rest is retrieved with the use of a stripping column.

The oil is boiled by steam, and the lighter hexane floats upward.

As it condenses, it is collected.

Refining the oil

6 - The oil is next refined to remove color, odor, and bitterness.

Refining consists of heating the oil to between 107 and 188 degrees Fahrenheit (40 and 85 degrees Celsius) and mixing an alkaline substance such as sodium hydroxide or sodium carbonate with it.

Soap forms from the undesired fatty acids and the alkaline additive, and it is usually removed by centrifuge.

The oil is further washed to remove traces of soap and then dried.

7 - Oils are also degummed at this time by treating them with water heated to between 188 and 206 degrees Fahrenheit (85 and 95 degrees Celsius), steam, or water with acid.

The gums, most of which are phosphatides, precipitate out, and the dregs are removed by centrifuge.

8 .

Oil that will be heated (for use in cooking) is then bleached by filtering it through fuller's earth, activated carbon, or activated clays that absorb certain pigmented material from the oil.

By contrast, oil that will undergo refrigeration (because it is intended for salad dressing, for example) is winterized—rapidly chilled and filtered to remove waxes.

This procedure ensures that the oil will not partially solidify in the refrigerator.

9 - Finally, the oil is deodorized.

In this process, steam is passed over hot oil in a vacuum at between 440 and 485 degrees Fahrenheit (225 and 250 degrees Celsius), thus allowing the volatile taste and odor components to distill from the oil.

Typically, citric acid at.

01 percent is also added to oil after deodorization to inactivate trace metals that might promote oxidation within the oil and hence shorten its shelf-life.
