The large rapeseed oil extraction equipment, also known as rapeseed oil extraction equipment, is developed and produced by Xinxiang Hongyang Company. Its significance lies in extracting the high-nutrient edible oil from rapeseed.

Principle and Process

The production process of rapeseed oil generally involves two methods: pressing and extraction (refining).

Pressing Method

The pressing method, also known as "physical pressing," involves using external force to squeeze the oil out of the oilseeds without the use of other chemical solvents, thus avoiding the residue of organic solvents in the oil. Xinxiang Hongyang Company's pressing process retains a significant portion of the effective components of rapeseed, including polyunsaturated fatty acids, as well as proteins, dietary fiber, vitamins, trace elements, and other nutrients beneficial to the human body, making it more suitable for specific health supplements.

Extraction Method (Refining Method)

The extraction method, also known as the refining method, involves using organic solvents (such as gasoline, ethanol, etc.) to extract the oil from the oilseeds. The extraction method uses solvent oil (light gasoline No. 6) to extract the oil from the raw material after soaking, followed by high-temperature extraction to remove the oil. Initially, the "oil" extracted is a mixture of organic solvents and oil, which is not edible and must undergo a series of refining processes (such as degreasing, degumming, dehydrating, deodorizing, deacidifying, decolorizing, etc.) before it can be consumed. This oil generally has a lighter color and a weaker or no natural seed flavor. The extraction process can almost extract all the oil from the oilseeds, making it a highly economic and widely used method in the modern oil industry.

Production Process

The production process includes harvesting and selecting rapeseeds, cleaning impurities, drying, roasting, pressing, crude rapeseed oil pressing, coarse filtering, fine filtering, and finally, rapeseed oil.

Rapeseed Oil

Rapeseed oil, commonly known as rapeseed oil or vegetable oil, is an edible oil extracted from rapeseeds. It has a golden or brownish yellow color and a slight irritating odor, often referred to as "green odor." This odor is due to the presence of a certain amount of sinapine, but the best rapeseed varieties do not contain this substance.

It is one of the main edible oils in China, mainly produced in the Yangtze River basin and the southwest and northwest regions, with the world's highest production. The human absorption rate of rapeseed oil is very high, reaching 99%. Rapeseed oil has the effect of softening blood vessels and delaying aging.

Since the raw material for oil extraction is the seed of a plant, it usually contains a certain amount of seed lecithin, which is very important for the development of blood vessels, nerves, and the brain.

Rapeseed oil contains little or no cholesterol, so people who need to control their cholesterol intake can consume it with confidence.

Rapeseed oil has a particularly high content of erucic acid, which may or may not cause myocardial fat deposition and damage the heart. Therefore, patients with coronary heart disease and hypertension should be cautious and consume it in moderation.

According to traditional Chinese medicine, rapeseed oil is sweet, pungent, and warm in nature, and can moisten dryness, kill insects, dissipate fireballs, and eliminate swelling and toxicity.
