canola→Magnitic seperating( Metal impurities)→cleaning →pressing-Crude canola oil

Main Equipments:

1. canola: It’s one of main oil seeds from human beings. It’s used to make canola oil around the world. The oil content in canola is about 28%-45%.

2. Magnetic selector: Clearing the iron impurities which might be in the canola, The iron impurity will be harmful to the following machines, so we need take the iron impurities out.

3.Cleaning sieve: This parts have different size cleaning sieves to clean the different

impurities.After going through this part,most of the impurities are moved from peanut.

4. Husking machine:this can help improve the oil yield from canolas,and reduce wear to the machine.

5.Presser machine: After pressing, you can get pressed canola oil, it is with high quality and eidble for human being.

extraction → mixed oil → evaporation→ steam-stripping → crude canola oil

Extractor types:

Level rotation extractor, loop type extractor, chain extractor

Extraction methods:

Use organic solvent through soaking or spraying contact methods to extract oil from oilseeds.

Advantages of extraction craft:

1.High oil yield, low residual oil in meal; 2.Low labor intensity;

3.Good working environment; 4.Good meal quality.

Negative pressure evaporation helps to improve crude oil quality.

Craft features:

1. Adopting negative pressure evaporation can ensure excellent oil quality;

2. Extraction system is highly adaptable, and can adapt to different raw material ;

3. All equipments are provided with exhaust gas absorption systems with excellent absorption effect;

4. Full energy-saving design utilizes heat energy for many times and saves steam consumption

Main Process:

crude canola oil → degumming&dephosphorization → deacidification → drying → decolorization → deodorization → defatting → dewaxing → product oil.

Refining methods:

oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.

Advantages of refining craft:

1. After refining the impurity of oil must be less than 0.2% ;

2.Recycling system save power and money;

3.Lower oil waste.

Craft features:

1. Continuous alkali refining shortens contact time between oil and lye,reduces saponification of oil,lowers refining consumption,and improves efficiency.

2. Decolorization adopts technology of combining premixing and steam mixing bleaching,which improves bleaching efficiency,saves consumption of bleaching clay,and it's simple and convenient to operate;and negative pressure state avoids oxygen in the air from contacting with hot oil,thereby ensuring oil product quality,inhibiting acid value to rise again,and lowering peroxide value.

3. Deodorization adopts new type continuous deodorization equipment which is applicable for deacidification and deodorization of plant oil with high acid value and low-resin content,the actual production proves its most obvious advantages are strong deacidification ability,excellent hot bleaching effect,high refining rate,good oil quality and so on.

4. The process has multiple heat exchange,which makes full use of the heat energy system,effectively reduces steam consumption,and also has the advantages of adjustable production process,flexible operation,high automatic degree,environment sanitation and so on.
