The role of shelling machines in modern sunflower oil extraction

In the world of edible oils, sunflower oil is prized for its delicate flavor, high smoke point and heart-healthy properties. While cookers and presses typically take center stage in modern sunflower oil extraction, sunflower seed shelling machines also play a key role in modern sunflower oil extraction, ensuring efficiency, quality and sustainability. Let’s take a closer look at the specific roles of shelling machines in modern sunflower oil extraction.

1. Separating Shells and Kernels to Improve Oil Yield

Sunflower seeds consist of a hard shell and a kernel. The kernel has a much higher oil content (about 40%-50%) than the shell (which contains almost no oil). The sunflower seed shelling machines used in modern sunflower oil extraction usually utilize mechanical force to break the shell and separate it from the kernel without damaging the precious oil-containing interior. By removing the shell, the subsequent sunflower oil extraction process can focus on the kernel, significantly increasing the oil yield per unit of raw material.

2. Enhancing the Quality of Sunflower Oil

Shells contain large amounts of fiber, pigments and other impurities. If shells enter the sunflower oil extraction process, they may introduce unwanted components into the sunflower oil, affecting its color, taste and shelf life. The sunflower seed shelling machines used in modern sunflower oil extraction can separate most shells, ensuring that the kernels entering the sunflower oil press machine are relatively pure. This reduces the workload of subsequent sunflower oil refining processes and helps produce high-quality, clear sunflower oil.

3. Improving Production Efficiency and Reducing Costs

The sunflower seed shelling machines used in modern sunflower oil extraction can automatically separate the shells and kernels, replacing the traditional manual or inefficient methods. This greatly reduces labor costs and increases the processing capacity of the sunflower oil extraction line. In addition, sunflower seed shells are hard and abrasive. If they enter sunflower oil extraction equipment (such as sunflower oil press machines or filters), they will cause mechanical wear, shortening the life of the sunflower oil extraction equipment and even leading to interruptions in the modern sunflower oil extraction process. It is worth mentioning that the sunflower seed shelling machines produced by Henan Glory Company can not only reliably handle modern sunflower oil extraction lines with large capacities (50 tons/day to 1000 tons/day), but also protect related sunflower oil extraction equipment and reduce maintenance costs.
