Corn Germ Oil making 
Using corn as raw material, in the process of producing corn bran, corn starch or corn starch sugar, about 8%-12% of corn germ can be recovered, which can be used to prepare corn germ oil and corn germ protein.

The process, equipment and operation technology of corn germ oil are basically the same as those of other oil materials, and must be cleaned→ dried→ softened→ flaking→ cooking→ pressed→  refined and so on.

Corn gearm Cleaning
The corn germ recovered from corn grits is mixed with much corn flour, corn bran, and needs to be sieved with a double vibrating sieve. The first layer of screen removes large impurities, using 1.5 × 1.5 mesh / cm; the second layer removes corn flour, minced meat and dander, with 4 × 4 mesh / cm, if the sieve is still mixed more for the cuttings, you can use 5 × 5 mesh / cm or 7 × 7 mesh / cm to reduce the loss of corn germ. The corn germ recovered from corn starch is mixed with impurities such as dander and radicle sheath, and needs to be continuously rinsed several times with clear water by a shallow pan or a launder. For example, a factory equipped with a cyclone separator can be produced by using a swirling flow. Centrifugation separates the germ.


The corn germ recovered in the process of making corn grits and corn starches contains higher moisture content after cleaning, the enzyme activity is stronger and is easily propagated by microorganisms, which results in the deterioration and rancidity of oil esters, which affects the yield and quality of oil products. It will reduce the utilization value of the cake. In order to maintain the freshness of the corn germ during storage and transportation, the cleaned corn germ should be dried or dried immediately until the moisture content is below 10%.
The first treatment of oil preparation for corn germ. The moisture content of the corn germ can be adjusted to below 10% while being heated, and the plasticity of the material germ can be changed, then the germ can be rolled into a certain thickness and not easily crushed. In order to prevent the protein from denaturing prematurely, and to make the material lose its elasticity, which affects the processing of rolling, cooking and press oil.

Flaking.  After softening treatment, the corn germ is rolled into 0.3 mm-0.4 mm slices by Roller Mill, which leads to the destruction of the cell structure, shortening of the oil path, and being convenient for cooking and pressing of the material.

The moisture content of the flaker is not less than 12% when the flaker is steamed and cooked in the cooker. After 40 minutes-50 minutes, the moisture content of the flaker is gradually reduced from 12% to 3%-4% when the temperature of the flaker is over 100 °, and you can smell it without burning it. During the whole process of steaming and cooking, the material is subjected to the double-action process of steaming and then frying, and at the same time, the moisture, temperature, plasticity and elasticity of the material are slowly regulated and controlled The destruction of the colloid structure of the denaturation and the decrease of the viscosity of the oil in the oil prepared the conditions for extracting the oil from the material.

Pressing. The methods of making oil and fat include pressing, extraction and water substitution. The equipment and production scale of the press method can be divided into screw press and hydraulic press. Since the production of corn germ oil is mostly carried out in a small scale and auxiliary workshop, it is suitable to use the screw press, which can be a production plant of a slightly larger scale, depending on the production scale, the screw press can be assembled with steaming and cooking equipment. Steam and cooking both, continuous operation, easy to use, steam and cook materials, oil in a group of equipment to complete. When the temperature of the steamed-cooked material is 115 °c-120 °C and the moisture content is 2%-4%, the material will be directly pressed into the press for oil. At this time, the room temperature should be kept at 30 °c-40 °C, the initial material input of the material is less, and the temperature of the press chamber will rise after the press is in normal operation Then evenly feed, oil and the cake output, can smell the cake aroma, cake solid, smooth surface, back crack, oil output normal. If steaming and cooking temperature is low, the material flaker moisture content is on the high side, the cake piece is soft, the water vapor is very thick, the oil color is not good, the white frothing, and the oil production reduces. If steaming and cooking temperature is too high, the flakers moisture content is too low, then the cake color is too dark, the export smoke and has a burnt taste, the oil color is deep, the oil output is also reduced. Normal operation of the press, the general oil press speed control for 8 RPM, material in the press chamber pressing time for 2.5 minutes, 5mm-6mm thickness of the cake. The yield of oil from corn grits is 22%-26%, the yield of oil from corn starch is 25%-28%, and the residual oil in corn cake is 5%-6%. The pressed oil, commonly known as crude oil without refining, contains 0.3% water and volatile matter, 0.2% impurities, 6% acid value, 6% precipitate, pale yellow color and normal smell, heated at 280 °C, The crude oil is not good for storage because of its high content of water and impurities. It needs to be refined by hydration, Alkali refining and deodorization to obtain high quality refined corn oil.
