Complete full set Oil Extraction machine  Oil Press Processing line

Product Description

​

1.Cleaning
Utilizes aerodynamic differences between cottonseeds and impurities for wind-based separation, effectively

removing light dust and partial heavy residues like stones.

2.Dehulling
Employs disc hullers with high-strength alloy steel tooth plates to crush shells through torsional force, offering

durability and low maintenance.

3.Kernel-Shell Separation
Rotating cylinder screens with angled beating rods achieve precise separation through differential rotational

speeds and directional impacts.

4.Flaking
Alloy rollers paired with hydraulic systems destroy cellular structures (flakes ≤0.3mm), while sealed designs

minimize solvent loss.
5.Cooking
Layered conditioning pots maintain uniform mixing (5mm blade clearance) and humidity via full-sealing,

enhancing flake integrity.

6.Pressing
Dedicated cottonseed oil presses achieve 5-8% residual oil with energy-efficient, compact layouts.
7.Filtration
Automatic slag-removal filters recycle residual oil and reduce impurities, supporting downstream degumming.

1.Degumming
Bag filtration removes solids, followed by phosphoric acid mixing and alkali neutralization to eliminate colloids and starch. Automated temperature control ensures precision.

2.Deacidification
Free fatty acids are neutralized via alkali treatment, reducing acidity to food-grade levels.

3.Decoloring
Preheated oil blends with activated clay (50t/day system) for 30-60min adsorption, achieving pigment removal. Armagh filters separate waste clay, with residual particles refined through precision filtration.

4.Deodorization
High-vacuum steam stripping removes volatile compounds, yielding odor-free oil.

5.Dewaxing
Controlled cooling crystallizes waxes, filtered to enhance oil clarity.

6.Degossypol
Solvent extraction or alkaline refining reduces toxic gossypol to <0.045%, meeting safety standards
