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

Pressing Method

The pressing method, also known as the "physical pressing method," uses external force to squeeze the oil out of the oilseeds without using other chemical solvents, thus avoiding residual organic solvents in the oil. Xinxiang Hongyang Company's pressing process largely retains the effective components in rapeseed—such as polyunsaturated fatty acids, proteins, dietary fiber, vitamins, and trace elements—which are beneficial to human health and suitable for targeted nutritional supplements.

Production Process

Harvesting and screening rapeseed → Rapeseed → Cleaning impurities → Drying → Roasting → Pressing → Pressed rapeseed crude oil → Coarse filtration → Fine filtration → Rapeseed oil

Rapeseed oil, commonly known as vegetable oil, also called canola oil or fragrant vegetable oil, is a type of edible oil pressed from rapeseed. The oil is golden yellow or brownish-yellow in color and has a certain pungent odor, known as "green odor" among the people, which is due to the presence of glucosinolates. However, premium varieties of rapeseed do not contain this substance.

Rapeseed oil is one of the main edible oils in China, primarily produced in the Yangtze River Basin, and in the southwest and northwest regions, with the highest production in the world. The human body can absorb up to 99% of rapeseed oil. It has the effects of softening blood vessels and delaying aging.

Since the raw materials for pressing oil are plant seeds, they generally contain a certain amount of seed phospholipids, which are crucial for the development of blood vessels, nerves, and the brain.

Rapeseed oil contains very little or almost no cholesterol, making it a safe choice for those who need to control their cholesterol intake.

Rapeseed oil has a particularly high content of erucic acid, and there is still debate on whether it can cause myocardial fat deposition and heart damage. Therefore, patients with coronary heart disease and high blood pressure should consume it with caution.

According to traditional Chinese medicine, rapeseed oil is sweet, pungent, and warm in nature. It can moisten dryness, kill parasites, reduce fire, and relieve swelling and toxicity.
