Different edible oils require different stages of refining. For example, peanut oil can be directly converted to domestic first-class oil provided it is discolored and deodorized, while rapeseed must undergo further dephosphorization and degreasing. Cottonseed oil needs to be de-molded, sunflower oil needs to be bleached and deodorized, and corn oil only needs to be bleached, des-sugar and degummed. The different methods of oil treatment are different and some sections do not make sense. When purchasing a complete set of oil extraction and oil refine machine equipment, we must understand our purpose and come up with a procurement plan that is tailored to our production needs.
Working principle of this mini vegetable oil refine machine small-scale edible oil refinery machine:
1. The mini sunflower corn oil refining machine for refining vegetable oil should be placed on a level surface.
2. After the wiring is connected properly, turn on the switch to debug whether the buttons on the control panel of the electrical box is normal.
3. After passing through the filter → the oil will be released into the hydration tank → turn on the low speed stirrer for heating → the system enters the heat preservation state → add a certain concentration of the saturated gel → turn on the high stirring speed → add the slightly boiling water → continue stirring at high speed → stirring to slow down → static heating, stirring to make it settle → discharge the saponin → heat → after dehydration → pump the oil into the fine filter decolorization tank → degumming oil finished → the process is completed.
Main Advantage of Oil Refine Machine:
1) Simple structure of linear type and easy installation and maintenance.
2) Adopting advanced components from China famous brands in electrical parts and operation parts.
3) Fully automatic and continuous work.
4) Running in high automation and intelligence without pollution.
5) Eco-friendly, low noise and power consumption
Main effect:
Degummed
Dehydration is the use of phospholipids and other insoluble hydrophilic impurities, a predetermined amount of hot water or dilute alkali, salt and aqueous phosphoric acid electrolyte solution are added with stirring into the hot crude oil, so that one of the gel of water absorption insoluble impurities added, then separated. This process uses the warm water type of hydration process, a small oil refinery in warm water method commonly used.In addition, by adding a certain amount of hydrated phosphoric acid, after the reaction, the oil into the non-hydratable phosphatide, becomes hydratable phosphatide. . Said phospholipid content is greatly reduced, you can achieve better results without sticking.
Deacidification
Crude oil contains a certain amount of free fatty acids, through refining, and crude oil can be in most of the large free fatty acids, the sodium salt of fatty acids does not dissolve generated in the oil, it becomes in substance of flocculation and sedimentation. Sodium hydroxide and fatty acid and generated sodium soaps, rapid response, and the resulting sodium soap surfactant adsorption and absorption capacity is strong, there may be a considerable amount of impurities, such as proteins, pigments, phospholipids and substances with Hydroxyl also in the sediment, suspended solids and even the spongy soap group can also be washed away, the most significant advantage of alkaline refining is that it has deacidification, disintegration, removal of solid impurities, the combined effects of discoloration.
Decolorization
In addition to its oil pigment prolapse, but also serve to reduce phospholipid content, peroxide number, soap amount, and the role of oil-containing metal ion content to improve color, taste and improve stability oxidative. The most widely used method is activated clay adsorption decolorization, that is, with clay that has a strong selective adsorption of this material, under certain conditions, in the removal of oil-soluble dve or with colloidal particles of the oil-dispersed pigment and other impurities, thus obtaining a better oil color.
