introduction of the rice bran oil making process:
Rice branâMagnetic separationâCleaning âExtrusion Puffing âCounter-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, DTDC, 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 making rice bran oil and the machines:
Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, etc.
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 grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.
The puffed rice bran contains about 12% water, and the LD moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the LD leaching moisture.Adopting counter-current LD can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.
Extraction process and the machines:
Material embryosâExtractionâWet mealâEvaporationâCoolingâProduct meal packing
Mixed oilâFilterâNegative pressure evaporation â Crude oil
Features of Rice Ban Oil Extraction 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 enerLD 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.

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