Our High-Capacity Commercial Oilseed Crushing Machinery is a professional-grade pre-press oil expeller engineered for industrial-scale vegetable oil production. Designed for unmatched durability and efficiency, this spiral oil mill machine operates continuously 24/7, 365 days a year, making it the ideal cornerstone for large-scale oil processing plants worldwide.

Specially optimized for rapeseed, peanut, sunflower seed, and persimmon seed, this machinery serves as a critical pre-pressing stage for solvent extraction or as a primary tool for double-pressing operations. By optimizing the structure of the pre-pressed cake, it ensures superior solvent penetration and delivers a higher quality of oil compared to traditional single-pressing methods.

Frequently Asked Questions

Q: Which oilseeds are most suitable for this commercial expeller?

This machine is specifically designed for high-oil seeds including rapeseed, peanut, sunflower seeds, and persimmon seeds, providing optimal extraction for each.

Q: What happens if the moisture content of the seeds is too low?

Low moisture can lead to cakes not breaking into tiles, increased motor load, and darker oil color. We recommend adjusting the steam pressure and feed valve immediately.

Q: Can this machine be used in a solvent extraction plant?

Yes, it is primarily used as a pre-press machine to create a loose cake, which significantly increases the efficiency of subsequent solvent extraction.

Q: How do I handle issues with oil foaming or white oil color?

This usually indicates the billet temperature is too low or moisture is too high. Gradually increase the steam pressure in the interlayer steamer to normalize.

Q: What is the typical residual oil content in the cake?

Under normal operating conditions, the residual oil content in the cake is approximately 13%, providing a high-quality base for further processing.

Q: Does this machine require a specialized installation team?

While the machine is designed for simple installation and maintenance, we recommend following the technical manual to ensure the 30KW motor and steam systems are correctly integrated.
