latest technics maize oil solvent extraction machinery

latest technics maize oil solvent extraction machinery

The whole production line contains three workshops: corn germ pretreatment & expansion workshop, corn germ extraction workshop, crude corn germ oil refining workshop

Part I  Corn germ pretreatment & expansion workshop

 1.1 Flow Chart:

Crude corn germ → cleaning  →   softening   →  expanding  →   drying →  to extraction workshop

Pretreatment and prepressing section is a very important section before extraction.

It will directly affect extraction effect.

1.2 Craft features:

1.Create good production 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 processes according to different materials.

Part II Corn germ oil extraction workshop

      ↓                                                                                 ↓       

extraction   → mixed oil   → evaporation→ steam-stripping  → crude corn germ oil

2.2 Extractor types:

Level rotation extractor, loop type extractor, chain extractor

2.3 Extraction methods:

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

2.4 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.

5.Negative pressure evaporation helps to improve crude oil quality.

2.5 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

Part III Corn germ oil refining workshop 

3.1 Flow chart:

crude corn germ oil → degumming&dephosphorization → deacidification  → drying → decolorization → deodorization → defatting  → product oil.

3.2 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.

3.3 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.

3.4 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 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.
