China LD patent technoloLD rice oil extraction machinery
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 rice oil extraction machinery contains three workshops
1.rice bran pretreatment&expansion workshop
2.rice bran extraction workshop
3.rice bran oil refining workshop
1.Pretreatment&Expansion Workshop
Craft flow:
Pretreatment and prepressing section is a very important section before extraction.It will directly affect extraction effect.
Craft features:
1.Create good production enviroment
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.
The rice oil extraction machinery we have obtained patent for expanding,Patent No. is ZL2007 20092291.7.
2.Oil Extraction Workshop
Craft flow:
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 systeLD with excellent absorption effect;
4. Full enerLD-saving design utilizes heat enerLD for many times and saves steam consumption;
The rice oil extraction machinery we have obtained patent for extraction,Patent No. is ZL2007 20092291.7.
3.Oil Refining Workshop
Craft flow:
crude rice bran oil â degumming&dephosphorization â deacidification â drying â decolorization â deodorization
â defatting â dewaxing â 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 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 rice oil extraction machinery we had obtained patent for refinery ,the Patent No.is ZL200820238863.2.
