Screw oil press is a common oil pressing equipment, widely used in food, chemical, pharmaceutical and other industries. It obtains oil by squeezing materials. It has the advantages of simple operation, low cost and high oil content.
The working principle of the screw oil press is to add the material from the hopper into the screw extrusion chamber, and squeeze out the oil and protein through the rotating screw. This equipment can process a variety of oils, such as peanuts, beans, rapeseed, etc. Its structure is relatively simple, mainly consisting of a feed port, a screw shaft, a pressing chamber, an oil outlet, etc.
The performance and effect of screw oil press are closely related to those of screw press. The main difference between them is that screw oil press adopts a more complex mechanical structure, which makes the oil compression more complete, thus improving the oil yield.
Advantages and features of screw oil press:
1. Compact structure, strong and durable;
2. The two spiral shafts are specially meshed in the pressing chamber, which is not easy to slide and has strong adaptability;
3. Twin-screw shear feeding solves the problem of high oil content and low fiber oil content making it difficult to squeeze;
4. It has large thrust and strong self-cleaning ability, and can adapt to the cold pressing of various oil products with high oil content;
5. The vertical cake unloading mechanism can support the pressing screw shaft in a centered manner, and the cake thickness can be adjusted in time during operation;
6. The cage is divided into vertical planes and supported by hinges at both ends, so there is no slag accumulation on the cage, the oil is discharged smoothly, and maintenance and repair are convenient;
7. The wearing parts are wear-resistant and have a long service life.
In addition, the screw oil press has the advantages of large processing capacity, simple operation and convenient maintenance.
Screw oil press application scope:
It is suitable for pressing shelled peanut kernels, tea seed kernels, sunflower seed kernels, cotton seed kernels, rapeseed kernels, walnut kernels, rubber seed kernels, shelled soybeans and other kernels with high oil content at room temperature or low temperature.
Suitable for hot pressing of traditional vegetable oil pressing process.
It is suitable for low temperature pressing of special oils such as flaxseed, safflower seed, almond, rose seed, etc. after hot pressing or shelling (shelling).
