Rice Bran Oil Machinery Introduction

1.Separating bran from fine broken rice section

The section is mainly used to remove broken rice and crude bran shell as well as other impurities, and it can reduce equipment failure,ensure normal operation,lower residual oil yield and solvent consumption.The screening method and wind separation method are usually used in the section. 

2.Rice bran softening and conditioning section

Before entering the expander,rice bran is heated in advance, temperature of rice bran before expansion is increased,and expansion quality of rice bran is improved.Softening pot is mainly used to soften rice bran,improve its plasticity so as to improve extraction efficiency.

3.Rice bran expanding section

The section is a process before oil extraction, expanded rice bran can improve extraction efficiency, lower solvent and steam consumption,and increase oil yield and quality of crude oil.Main machine is rice bran expander.

4.Rice bran drying section

Using plate dryer to adjust the moisture and temperature to suit for extraction.

5.Extraction section

Oil extraction is an advanced oil production craft, now widely applied to oil plants,and it’s an organic solvent extraction method,oil is extracted from rice bran by contact(soaking or spraying) of solvent and rice bran.

The advantages are as following:

1. 1. high oil yield, low residual oil rate of meal;
2. 2. low labor intensity;
3. 3. good working environment;
4. 4. good meal quality.

6.Desolventizing-toasting section

 The meal from extractor contains 25-35% solvent, for recovering solvent and getting better meal, solvent can be toasted by heating.High material layer toaster is usually applied to remove solvent from meal as well as dry extracted meal; DTDC desolventizer should be used for extracted rice bran meal.

7.Evaporation section

Solvent of mixed oil is vaporized by heating to improve oil concentration of mixed oil, i.e. volatile solvent is separated from nonvolatile matters. Long-pipe evaporator(also named raising film evaporator) is widely used for this section.

8.Steam-stripping section
Use steam distillation to reduce boiling point of mixed oil,so as to remove trace solvent off at lower temperature.   

9.Crude oil degumming section

Add hot water and food grade phosphoric acid to mix with crude rice bran oil to finish degumming, mainly removing phospholipids,protein, grume and trace metal ions.Separate oil foots from oil with centrifuge, then dehydrate and dry oil.

10.Alkali refining deacidification section

Add caustic soda to neutralize free fatty acid to form sodium fatty acid,which will be separated from oil.

11.Decolorization section

Mix active bleaching clay with oil under vacuum condition for adsorption bleaching,and use leaf filter to remove waste bleaching clay.

12.Deodorization section

Under high temperature and high vacuum condition,utilize water vapour distillation to remove odor of oil.  

13.Dewaxing & defatting section

Utilize winterization crystallization method to remove wax and fat,then through filtration separate wax and fat from oil. 

Henan Huatai can provide you with 10 to 25 kilograms (test equipment), 2 to 1,000 tons / day of oil refining projects , Henan Huatai naturally is your preferred partner for different oil quality. in Henan Huatai here are different options, batch chemical refining, semi-continuous physical refining, continuous physical refining program, where Henan Huatai provide you with the design (process, civil, electrical), manufacturing, installation, commissioning, training of technical personnel to the sale a full-service; advanced automatic control system to ensure that the entire production line of automatic, smooth operation; heat saving each segment to ensure that the processing costs to a minimum.

The main refining plant processes: degumming, dehydration, bleaching, deacidification, deodorization, dewaxing, degreasing. Crude oil in squeeze, extraction crude oil 
can be obtained national quality standards of edible oil through 
refining plant 
.

Refining workshop process: fully continuous refining equipment, refining equipment, and semi-continuous batch refining equipment.

Huatai Oil refining machinery characteristics:
1, continuous alkali refining shorten the contact time of oil and lye, reduce fat saponification, low power consumption and improve efficiency;
2, bleaching and steam stirring decolorization premixed combination of technology, improve the decolorization efficiency, saving the amount of clay, simple operation; a negative pressure and oxygen in the air to avoid contact with hot oil, to ensure the quality of oil, acid value rise suppression, reduce excessive oxidation number.
3, using the new continuous physical refining deacidification deodorization, deacidification deodorizing suitable for high acid value and low gum content of the vegetable oil, the actual production proves that the process has the following salient features: strong acid removal ability, good heat decolorization, refining rate, good quality oil.
4. The process multiple heat exchange systems take advantage of the heat, reduce steam consumption, the production process also has an adjustable, flexible operation, high automatic degree of sanitation.

Applicable oil: soybean oil, sunflower oil, rapeseed oil, cottonseed oil, peanut oil, palm oil, copra oil, rice bran oil, animal oil all need refining oil.

Refining plant capacity: 10-1000T / D
