Double Decolorization Rice Bran Oil Making Machine

Double Decolorization Rice Bran Oil Making Machine

Introduction Of Rice Bran Oil Making Machine:

Rice bran→Magnetic separation→Cleaning →Extrusion Puffing →Counter-current

A.There are mainly three parts in the rice bran oil making process, pretreatment, leaching (extracting) and refining.in this oil making process,the Essential oil equipments have to used,such as extraction machine, LD, refining pot, degumming pot and so on.

B.After the refining of five steps about de-, we can get the grade 1 rice bran oil,you can get different grade oil with different equipment, the detail information we will talk in our specific condition.

Pretreatment Process Of Rice Bran Oil Making Machine:

Cleaning Process:

Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, etc.

Extrusion Process:

Adopting the expander can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on the one hand, can make solution lipase in the rice bran passivated under high temperature and high pressure condition,then prevent the rice bran oil rancidity; On the other hand, the extrusion puffing can make rice bran be porous material , and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.

Drying Process:

The puffed rice bran contains about 12% water, and the moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the leaching moisture.Adopting counter-current dryer can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.

Extraction Process Of Rice Bran Oil Making Machine:

Solvent recovery

Features of Rice Bran Oil Making Machine:

1. Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect;

2. The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;

3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity.

5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.

Hydration Degumming & Alkali Refining Deacidification Process

Continuous Refining Decoloring Process

The main function of decoloring process is to remove oil pigment, residual soap and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.

Continuous Refining Deodorizing Process

Rice Bran Oil Automatic control degrease workshop

Oil refining means separating impurity from oil based on the different characteristics of oil and impurity, in order to enhance the stability and security of oil. Oil refining including two technologies, physical refining and chemical refining.echnological process details of Double Decolorization Rice Bran Oil Making Machine:
AAA1

1. Acid reaction process
Oil temperature can be adjusted by screw plate heat exchanger. When the temperature is heated to about 80℃, mixing about 85% food grade phosphoric acid into acid reaction tank for reacting. In the tank, most non-hydrated phospholipid transfer into hydrated phospholipid.
AAA1

2. Neutralization process
In the neutral section, degummed oil with appropriate temperature and the appropriate concentration of alkali liquor, into the neutralization centrifugal mixer mixing, in order to achieve the effect of mixed, the mixture is then sent to neutralization tank for enough time, in this process, excessive alkali neutralization of free fatty acids and some phosphate form soapstock , after pumping oil soap mixture into heater oil heating to 85 ~ 90 ℃ in centrifuge separation oil - soap (or oil - glue). Oil soapstock of the separated (or foot) feet into the oil tank, and then to the salting out with soap pump tank isolated part of the oil.
AAA2

3. Washing process
Neutral oil from separator, still contains about 500 ppm soap, in order to reduce the residual content of soap, oil is joined by about 10% of hot water, washed in the washing mixer, hot water will absorb oil soap and other impurities, then in the water separator are separated.
