Corn germ oil machinery
Corn,a good material which is treasure of the whole body,it could be flour,starch,oil and more.If corn oil plant,it has process into corn germ from fresh corn.
When oil press operating, the prepared materials enter the pressing chamber from the hopper and then move forwards by the rotating of pressing screw and is pressed under the high-pressure condition in the chamber, friction between material and chamber will be created, which also created friction and relative movement among material particles, on the other hand, root diameter of the pressing screw carries larger from one end to the other. hence, when rotating, it not only pushed particles moving forwards but also turns them outwards as well, meanwhile, particles adjacent the screw will rotation along with screw’ rotating, causing every particle inside the chamber to possess different speed, therefore relative movement among particle creates heat which is necessary during manufacturing. because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil productivity.
There is rich impurity in the crude corn oil,such as fatty acid,waxiness,soap and more,so the crude corn oil have to refine before eating.The flowing is oil refining machine of corn oil plant.

Corn oil plant main process:
Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.
Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.
Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.
Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.
Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).
