What is the rapeseed oil production process?

Rapeseed oil is a common vegetable oil that is extracted from rapeseed. The production process of rapeseed oil includes multiple steps such as pretreatment, rapeseed oil press, solvent extraction, filter, and refining. If you are interested inrapeseed oil production process or are ready to set up a rapeseed oil processing plant, Henan Glory Company can provide not only a complete set of rapeseed oil production equipment but also help you to design your factory depending on your requests and your budget, but what is the rapeseed oil production process, let’s explain it to you today.

For the rapeseed oil production process, we explain according to different production and quality requirements:

1. If the capacity is less than 5 tons, you can directly use the screw oil press machine, which is very simple and easy to operate and has very high efficiency. Or you can use our automatic temperature control all-in-one machine, our automatic temperature control all-in-one machine can automatically adjust the temperature, and bring a small frying pan to help you get more oil while heating up the oil, our all-in-one machine It also comes with two filter barrels, which can help you get cleaner oil. Our all-in-one machine has a processing capacity of 1.3 tons to 11 tons per day for your choice.

2. There are two options for the capacity of 5-10tons, one option is the screw oil press equipment, and the other is small scale production line, including roaster, press and filter. Before extracting oil, roast the rapeseed in the small roaster, it will improve the oil yield and make the flavor of rapeseed oil better. Rapeseed oil press equipment uses the action of external mechanical forces to press the pre-treated rapeseed, squeezing the oil out of it to obtain pressed rapeseed oil. Our oil press machine has the characteristics of low residual oil rate, good quality, easy operation, good-looking appearance and so on. Filtration - The plate filter removes impurities layer by layer and takes away part of the water.

3. If the capacity is 10-30tons, we recommend pretreatment equipment before pressing and filtering. After the rapeseed is pre-treated, you can obtain higher quality rapeseed oil, the rapeseed oil production process and equipment are as follow, pretreatment equipment includes vibrating separation, magnetic separator, destoner, crushing equipment, softening equipment, cooking etc, the main purpose is to remove various impurities and moisture conditioning, improving the quality and yield of rapeseed oil.

4. If the capacity is more than 30tons, the pre-press solvent extraction method can be used in the rapeseed oil production process. The rapeseed oil obtained by rapeseed oil press equipment does not contain additives, and its nutrient content is relatively ideal, but the content of residual oil in the cake after pressing on the rapeseed oil press equipment is high. Therefore, if the budget is sufficient, and there are higher requirements for the yield and quality of rapeseed oil, oil refineries often use pre-press solvent extraction to increase the yield of rapeseed oil, which requires the use of rapeseed oil solvent extraction equipment. The rapeseed oil solvent extraction equipment uses the solvent(n-hexane) in full contact with the oil to produce oil, and the oil contained in the rapeseed oil is leached to extract blended oil. Rapeseed oil extractor produces rapeseed oil with high extraction efficiency, but the crude oil extracted by rapeseed oil extractor contains a small amount of solvent residue, and the extracted crude oil must be refined.

Refining equipment - through the steps of degumming, deacidification, decolorization, deodorization etc. The rapeseed oil refining process is used to remove gums, FFA, pigments and bad odors, aiming at improving the rapeseed oil storage stability, flavor and color. Henan Doing Company's rapeseed oil refining equipment has three kinds of intermittent, semi-continuous and fully continuous, which can be selected according to the output. The first-grade oil can be sold to the market.
