What Equipment Is Essential for High-Quality Perilla Oil Production?

Perilla Seed Oil is a highly unsaturated oil extracted from the seeds of the perilla plant. It contains a large amount of unsaturated fatty acids, primarily composed of essential fatty acids required by the human body such as oleic acid, linoleic acid, and linolenic acid. Notably, its α-linolenic acid content is as high as approximately 67%. It also contains various nutrients like vitamin E, giving it high nutritional value.

Perilla seed oil processing typically employs the physical pressing method. This process relies on oil presses to physically squeeze out the oil, allowing the produced oil to retain more nutrients. The cold pressing process further minimizes nutrient loss during production, resulting in oil that is more nutritious and healthier. However, pressing alone cannot fully extract the oil, leaving a high residual oil content in the cake (meal)To fully utilize the oilseed material, some manufacturers adopt a combined pressing and solvent extraction process to extract perilla seed oil. First, the oil press extracts the majority of the oil. The resulting pressed cake is then crushed and sent to solvent extraction equipment to extract the remaining oil. This approach both fully extracts the oil, improving the oil yield, and produces high-quality meal.

Finished perilla seed oil must meet the standards stipulated in edible oil quality regulations to be a qualified commercial product. Therefore, oil produced by both pressing and solvent extraction processes requires refining treatment. Crude oil contains various impurities, such as sediment and meal powder introduced during processing, as well as phospholipids, pigments, free fatty acids naturally present in the oil, and contaminants from the raw material harvesting process. The presence of these impurities is detrimental to human health and negatively affects the quality and appearance of the finished oil. Consequently, during production, refining equipment is used to remove impurities through processes like degumming, deacidification, decolorization, deodorization, and dewaxing, yielding a healthy edible oil that complies with national standards.

Refining equipment plays a vital role in edible oil production. It determines the quality and healthfulness of the finished oil and is an indispensable part of the edible oil production line. The quality of the refining equipment and the refining process determine the quality and yield of the finished oil. Therefore, during equipment selection, it is crucial to focus on the equipment quality and the manufacturer's after-sales service. Choosing to collaborate with a manufacturer possessing strong technical capabilities and a comprehensive after-sales service system provides a solid foundation for the long-term stable operation of the oil mill.
