Vegetable oil extractor: what is this and why is it used

Extraction is a popular way to extract vegetable oil. This method allows increasing the yield of the product. Extractors are a universal type of equipment used in production process. The extraction method of oil production can be used both in its pure form and in combination with mechanical pressing, which will allow you to get even more product. Vegetable oil extractors Extraction is the process of transferring oil from an oil-containing material to a solvent by means of molecular and convective diffusion. Continuous extraction is the main method for the degreasing of oilseeds. During the extraction process, the solvent can move either towards the raw material or in the same direction as it. In the first case, the process is called countercurrent, and in the second – forward flow. Extractor operation principle The entire extraction process includes 4 main steps: Continuous methods are used to extract oil from raw materials. […]

How vegetable oil is refined

Vegetable oil is one of the key ingredients in the food industry. It is widely used for cooking and food production. However, crude vegetable oil usually contains undesirable impurities such as free fatty acids, waxes, pigments, seed residues, and other substances that can affect quality and stability of oil. To remove these impurities, a refining process consisting of several stages is carried out. We tell you how oil is refined. The main stages of the vegetable oil refining process Refining process includes several stages, each of which removes different impurities from the oil. Water degumming and neutralization The first step in the refining process is water degumming and neutralization. The crude vegetable oil is treated with steam or hot water, which moisturizes it and removes phosphorus and other hydrophilic substances. A neutralizing agent, usually an alkali, is then added to the oil to bind free fatty acids and other acidic […]

Are vegetable oils obtained by means of solvent extraction method  safe?

One of the most efficient methods of edible oil production is solvent extraction. In this process, the oil cake, i.e. the material from which the oil is extracted, is immersed in a solvent. The combination of heat and solvents is able to separate and extract the oil from the raw material of plant origin. The use of an extraction line allows you to get more oil from raw materials than with a technology that uses only a screw oil press, so this method is popular with manufacturers. But consumers often have a question: Is solvent-extracted oil safe? To answer this question, it is necessary to explain some details of the extraction process. Solvent extraction process of vegetable oils Extraction is the process of obtaining the oil from the cake using solvents. For efficient operation of the line, the seeds are preliminary pressed, which significantly increases the oil yield. Main steps […]

What is oil deodorization and why is it done?

Дезодорація — це процес видалення з олії та рослинних жирів одорантів, пігментів та домішок. В цьому процесі певна кількість очищувача, яким виступає пара, пропускається протягом певного періоду часу через гарячу олію під низьким тиском.
