Rapeseed Oil Refining Process

2025-06-06

As one of the important edible oil varieties in the world, the refining process of rapeseed oil directly affects the stability, flavor and nutritional value of the oil. Modern rapeseed oil refining process systematically removes impurities through physical and chemical means, and realizes the quality upgrade from crude oil to finished oil. The following process flow, key parameters and technical points are analyzed. I. Pre-treatment stage: laying the foundation for refining Gross oil pretreatment Rapeseed oil should be settled to remove surface foam, adjust the oil temperature to 25-35℃ and keep the oil surface smooth. At this stage, it is necessary to test the acid value of the oil, phospholipid content and other indicators, for example, if the acid value exceeds 3mg KOH/g, it is necessary to increase the intensity of alkaline refining. Lye preparation According to the characteristics of the oil, make 20-30°Bé lye at the ratio of 1kg caustic soda + 5kg water, and make sure the lye is completely dissolved by circulating pump. The concentration of lye should be dynamically adjusted according to the free fatty acid content, for example, for every 1mg KOH/g increase in acid price, the concentration of lye should be increased by 0.5°Bé. Second, the core refining process: multi-dimensional quality improvement 1. Lye refining and deacidification: the key link of chemical neutralization Operating parameters: after the oil temperature rises to 60 ℃, add lye in 5-10 minutes at an even speed, stirring speed from 20r/min to 60r/min, neutralization time control in 1 hour. Soap foot separation: the temperature rises to 65 ℃ to stop stirring, standing 4-6 hours after the discharge of soap foot. Need to control the oil content of the soap foot is less than 3%, otherwise it needs to be centrifuged through the second recovery. 2. Soap washing: fine control…

How much oil does soybean oil press machine produce per hundred pounds?

2025-06-05

The oil yield of soybean oil press is the core index to measure the performance and economic efficiency of the equipment, which directly affects the operating cost and market competitiveness of the oil mill. According to industry data and equipment testing, soybean oil presses per 100 pounds of soybean oil yield is usually between 12-18 pounds, but the actual value of the quality of raw materials, pressing process, equipment type and operating practices and other factors. In this paper, from the technical principle, raw material differences, process selection and equipment optimization dimensions, systematic analysis of soybean oil press fluctuations in oil yield mechanism. First, the quality of raw materials: soybean oil content and the key role of pretreatmentThe oil content of soybeans is the basis for determining the oil yield. Domestic soybean oil content is generally 16% -18%, while the oil content of imported soybeans (such as U.S. genetically modified soybeans) can be up to 18% -20%. This difference stems from the selection of varieties and planting environment: imported soybean due to large-scale planting and genetic improvement, seed fullness is higher, oil accumulation is more adequate. For example, an oil mill using domestic soybeans, every hundred pounds of oil output stabilized at 15-16 pounds; switch to imported soybeans, the oil yield increased to 17-18 pounds, directly reflecting the decisive impact of raw material quality on oil yield.Pretreatment process is another key link to improve the oil yield. The hot pressing process requires soybean screening, crushing, steaming and stir-frying steps, of which the stir-frying temperature needs to be controlled at 110-120 ℃, in order to destroy the cell structure and reduce the viscosity of oil. If the steaming and frying is insufficient, the cell wall is not fully ruptured, the oil yield may be reduced by 2-3%; if excessive steaming and…
