Automatic Sunflower Oil Extraction Machine

We are HUATAI OIL MACHINERY with more than 60-year experience in Sunflower Oil Extraction Machine. Huatai is dedicated to providing complete solutions of Oil Milling to Oil Refining and the leading supplier and exporter of Palm Fruit Oil Mill Plants in China. The complete array of machines and equipment give excellent crushing efficiency.

1. Sunflower oil pre-press process

Raw seeds - cleaning impurity - dehulling - flaking - Cooking - Pre-ressing

First, use magnetic separator, destoner and vibrate cleaning sieve to remove metals, small stones, impurities from sunflower raw seeds.

Second, husking machine is used to remove husks, separating screen to separate husk and sunflower kernel, here separating screen must not separate completely, or it will be too slippery for oil pre- press.

Third, cooking sunflower seeds are ready for oil pre-press.

Fourth, pre-press sunflower seeds. Here only pre-press part of sunflower oil, oil residue inside cake (about 12-16%) will be extracted in oil extraction process. After pre-pressed, the crude sunflower oil will be delivered directly to sunflower oil refining, and pressed cake to oil extraction.

2. Sunflower oil extraction process

The extraction machines Huatai produces will meet your requirement for oil extraction, high efficient and low consumption.

First, extract oil from sunflower oil cake inside oil extractor after solvent mixing, and the final products are mixed oil and wet meal.

Second, the mixed oil will pass through two evaporators to make solvent inside transform into gas, and solvent will be recovered through condensers and reused. These two evaporators are not with same size, the first evaporator is bigger than the second one because there are more solvent inside mixed oil in the beginning. After evaporating, the oil will be pump into the stripping tower. Finally, we will get crude sunflower oil ready for oil refining.

Third, the wet meal will be delivered to desolventizer to dry and be separated with solvent. The dry meal will be packaged for sale as animal feed, in which oil residue inside meal is less than 1%.

1. Sunflower oil refining process

Crude oil AcA A degumming AcA A deacidification AcA A decolorization AcA A deodorization AcA A refining oil

First, degumming is mainly to remove phosphatide inside crude sunflower oil in order to reduce oil loss and improve quality of oil. Second, decoloration using bleaching clay to absorb darker colorant inside crude oil. Third, deodorization is using high temperature to remove the impurities with bad smell. Forth, dewaxing is using low temperature to freeze wax inside refined oil and then separate wax with vibrating screen.

Technological Characteristic:

1. Strong deacidification capacity

2. Good decolorization effect

3. Excellent oil quality
