6YL series screw oil press machine boasts strong pressing structure and automatic heating system for highest oil output. Different from traditional small oil screw press, 6YL adds an automatic heater to increase the oil output rate by hot extrusion. This automatic oil press machine is ideal for vegetable oil making, from small oil pressing workshops to large-scale oil extrusion factory.

Main advantage of screw oil press machine:

1. High oil yield, small space occupied and low expense on equipment and electriciy.
2. Multi-functional used for pressing various of oil crops.
3. Simple operation and stable production performance.
4. Various machine models for options according to the capacity.
5. Widely used by small workshop and factories and hot selling at home and abroad.

Screw Oil Presser Working principle:
When the oil press is running, the processed material embryo enters the squeezing chamber from the hopper. The helix of the squeezed screw is pushed in and squeezed. The material embryo is carried out in the pressing chamber of the oil press. Under the condition of high pressure, there is a great friction resistance between the material embryo and the squeezing and squeezing chamber. The heat caused by the heat caused the thermal denaturation of the protein in the embryo, destroyed the colloid, increased the plasticity, and also reduced the viscosity of the oil and thus precipitated oil easily. The oil production rate of the oil press is improved.(See more: Factory Supplier

Main Steps of Making Sunflower Oil:

(1) Seed Cleaning: It is the first step to help ensure that a quality oil and meal are obtained. Aspiration,indent cleaning, sieving, or some combination of these are used in the cleaning process. During processing,meal quality can be affected by temperature and other factors.
(2)Pre-conditioning and Flaking: The cleaned seed is first heated to about 30-40ºC to prevent shattering. Some moisture adjustment may also be required. The preheated seed is then flaked on roller mills, set to very tight clearance.
(3) Cooking:The flaked seeds are then heated to about 75-100ºC in cookers. An important function of the cooking operation is to control enzymatic activity in the flaked seed, which depends on temperature and moisture content.
(4) Pressing: The heat-conditioned seed is passed into continuous sunflower screw oil press machine or expellers to reduce the oil content of the seed from about 42% (8% moisture basis) to 16-20% mechanically.
(5) Refining: To ensure good stability and shelf-life, the crude oil goes through a series of refining processes to remove compounds like phospholipids, mucilaginous gums, free fatty acids, colour pigments and fine meal particles.
