The whole edible oil pressing line contains a pre-treatment process and press process, Using a magnetic separator, weighing scale, and screener to remove impurities from the seeds. Crushing the oilseeds to ensure a good softening and flaking effect.
The main processes include Seed Cleaning & Weighing, Cracking, Flaking, Cooking, Pressing, and Filtering.
Cleaning
Using a magnetic separator, weighing scale, and screener to remove impurities from the seeds.
Cracking
Crushing the oilseeds to ensure a good softening and flaking effect.
Flaking
The roller flaker can crush and flake uniformly the broken seeds into thin flakes for the oil mechanical pressing.
Cooking
Using heating and cooking to adjust the temperature and moisture of the seeds, improving oil yield.
Pressing
Pressing the high-oil material to get oil and cake, then treated by solvent extraction.
Filtering
Separating oil residue by oil drag conveyor firstly, crude oil then enters to settling tank for further separation. Crude oil from the settling tank is pumped to a horizontal screw centrifuge or leaf filter for further removing impurities.
