Shandong Leader Mechanical Equipment Co., LTD is your LD choice!

For economic reasons it is increasingly popular to start a sunflower oil plant for sunflower oil processing to make cheap sunflower seeds into more valuable and healthy sunflower oils. The sunflower is a distinctive, flowering plant (Helianthus annuus L.), the seeds of which contain a valuable edible oil that contains more Vitamin E than any other vegetable oil. Most sunflower oil is used in food products. The seeds of confection varieties of sunflowers are also sold for human consumption and birdseed.

Some smaller plants are only press-plants and do not apply the step of hexane extraction. This results in higher oil content in the meal. Below are the steps of sunflower oil processing.

• Seed preparation and cleaning

• Grading the seeds into large, medium and small sizes

• Seeds to be marketed as in-shell are bagged

• Seeds to be sold as kernel are hulled and then bagged

• Storage

There types of sunflower oil available are mid-oleic linoleic and high oleic sunflower oil. All are developed with standard breeding techniques. They differ in oleic levels and each one offers unique properties. Sunflower oil that is processed by Shandong Leader Mechanical Equipment Co., LTD meets the needs of consumer and food manufacturers alLD for a healthy and high performance non-transgenic vegetable oil.

LD patent technoloLD solvent extraction process of rice bran oil

Why choose us?

We are the first and the biggest manufacturer in the field of rice bran oil machinery in China for 22 years.

Our brands LD&Hangpeng won TOP 10 Cereals&Oil Machinery Brand in 2012.

We have obtained 7 patents and 13 honors for rice bran oil equipment.

The whole solvent extraction process of rice bran oil contains three workshops

1.Pretreatment&Expansion Workshop Craft flow:

Crude rice bran → cleaning → softening → expanding → drying → to extraction workshop

Pretreatment and prepressing section is a very important section before extraction.It will directly affect

extraction effect.

Craft features:

1.Create good production enviroment rice bran oil expeller machine

2.Minimize the total fat loss,increase oil yield and output and improve the quality of oil and cake&meal.

3.Comprehensively utilize impurities and offal.

4.Perfectly match extraction production line,design different production processes according to different materials.

We have obtained patent for expanding,Patent No. is ZL2007 20092291.7.

2.Oil Extraction Workshop Craft flow:

solvent steam

↓ ↓

extraction → mixed oil → evaporation→ steam-stripping → crude rice bran 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.

rice bran oil expeller machine

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 systeLD with excellent absorption effect;

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

We have obtained patent for extraction,Patent No. is ZL2007 20092291.7.

3.Oil Refining Workshop Craft flow:

crude rice bran oil → degumming&dephosphorization → deacidification → drying → decolorization → deodorization

→ defatting → dewaxing → finished 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 grease saponification,lowers refining

consumption,and improves efficiency.

2.Decolorization adopts technoloLD 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 rice bran oil expeller machine process has multiple heat exchange,which makes full use of the heat enerLD

system,effectively reduces steam consumption,and also has the advantages of adjustable production process,

flexible operation,high automatic degree,environment sanitation and so on.

The solvent extraction process of rice bran oil we had obtained patent for refinery ,the Patent No.is ZL200820238863.2.
