New technology maize oil production plant

The production capacity of a New technology maize oil production plant is between 1.5 and 10 kg of solid per m2 of filtering surface. For every filter press model, the chamber volume and the filtering surface depend on the number of Cooking oil making machine of complete set certificated by CE ISO BV plates.In practical terms pressing times are less then four hours. Filtration time depends on:cake thickness,sludge concentration,specific resistance,compressibility coefficient.One of the advantages of the Shandong Leader Machinery Co.,ltd. is that it can accept sludge with average filterability. New technology maize oil production plant is always advantageous to optimally thicken sludge before filter press operations.When the Cooking oil making machine of complete set certificated by CE ISO BV has stopped, the filtrate circuits and central duct, which is still filled with liquid sludge, are purged by compressed air.Shandong Leader Machinery Co.,ltd. Washing of clothes should be carried out every 15-30 processing oprations. For mid- or large units this take place on press using water sprayers at very high pressure (80-100 bar).

New technology maize oil production plant

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 might be in the peanut. 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 peanut oil refinery workshop, and the cake will sent to peanut oil extraction workshop.

2.Craft flow for corn oil extraction workshop

solvent

↓

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

Wet meal → DTDC toaster → corn cake

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 the 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 .

The standards of refined corn oil

The oil machine is suitable for different materials, but the process of each materials is different. If you really need to process oilseeds, welcom to know much from us. The main materials is palm, palm kernel, rice bran, peanut, sunflower, corn germ, soybean, sesame, cottonseeds and so on.

New technology maize oil production plant

After finish degumming process about New technology maize oil production plant, at once add into lye carrying alkali refining deacid, lye concentration 16 ° Be ′, super alkali is 0.1to0.3% oil weight, after finish adding, continuous stirring 30min, when soap particles accumulated condensing, should reduce stirring speed, 30r/min avoid emulsion. After adding alkali, gradually rising temp to the end temp 65 ° C, see to that the rising temp speed should control at 1 degree per minute, not too fast. Shut off neutral pot drive part, theoil settled in the pot 6-8 hours, make oilseparate from soap.
