Fully automatic Sunflower seed oil extraction/crude oil refinery process with lower consumption

Fully automatic Sunflower seed oil extraction/crude oil refinery process with lower consumption

Oil production process includes three important parts :oil material pretreatment process,

oil solvent extracting process and oil refining process.

1.Oil material pretreatment process

1. Create a good product environment.

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 processing according to different raw materials.

2.Solvent extraction process

1,Adopting negative pressure evaporation can ensure excellent oil quality

2,Extraction system is highly adaptable and can adapt to different raw materials

3,All equipment is 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.

3. Refining process

1. Continuous alkali refining shortens contact time between oil and lye ,reduces grease

saponification ,lowers refining consumption ,and improve efficiency

2. Decolorization adopts the technology of combining premixing and steam mixing bleaching ,

which improves the efficiency ,saves the consumption of bleaching clay , and it is 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 equipments which is applicable for

plant oil deacidification and deodorization of 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 ,steam economization ,good oil quality and the like

4. The process has multiple heat exchange, which makes full use of heat energy system,

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

process,
