99% oil yield maize oil extracting machinery of cooking oil production line

Specifications

99% oil yield maize oil extracting machinery of cooking oil production line.

The whole corn oil machine contains three workshops: Oil seeds pretreatment and prepressing

workshop, solvent extraction workshop and oil refining workshop.

1.Craft flow for corn oil pretreatment and prepressing workshop

Corn germ→ magnetic box→ cleaning→ flaking roll → cooker →oil prepressing →to extraction

workshop

Main Equipments:

1. Materials:Peanut , sunflower seeds , rapeseeds, soyeban, rice bran and other oil seeds . 2. Magnetic box: Clearing the iron impurity which migLD be in the corn germ. Since in the

process of puffing, the iron

impurity will be harmful to the screw of extrusion machine, affect the puffing effect.

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities.

4. Crusher: Because of the big size of oil seeds. It need to be crushed to small pieces.

5. Cooker: This machine can adjust the water content of the oil seeds.

6. Prepressing: This machine is used to take parts of the oil from high oil content oil seeds.

Then the crude oil will sent to corn oil refinery workshop, and the cake will sent to corn oil

solvent extraction workshop.

solvent

↓

extractor → mixed oil → 1st and 2nd evaporation → stripping tower → crude corn oil

Wet meal → DTDC toaster → corn meal

Main Equipments:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Roary extractor: spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

3. DTDC: used to separate the solvent from the wet meal.

4. Miscella tanks: Purifying the miscella.

5. Miscella stripping: it will remove the remaining solvent in miscella.

6. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for

recycling.

3. Craft flow for corn oil refining workshop

Crude oil → degumming and deacidification→ decolorization →deodorization → refined oil.

Main Processes:

1. Degumming and deacidification: The gum is moved by phosphoric acid and hot water. There

are two ways to move the acid in the peanut oil. One is chemical way, the other one is physical

way. The chemical way is using NaOH to react with acid. This way is suitable for capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is

used for capacity from 30-600T per day.

2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the cooking oil accor-ding to the requirement of your market.

3. Deodorization: The function of this step is to move the special smell in the oil. This is an

important standard for refined oil. Because of the good smell of peanut oil, you can choose

this step according to your market.

4.Dewaxing section: Because there is some wax in the corn oil , if you want to get the first grade corn oil , you need to remove it .
