If you’re looking for an efficient solution to remove sunflower seed shells and streamline your processing workflow, a professional sunflower seed shelling machine is the key. This equipment is designed to solve the pain point of manual dehulling—saving time, reducing labor costs, and ensuring consistent results. Below, we’ll detail its core capacity, complete processing steps, and how each component works together to optimize sunflower seed processing.
The sunflower seed shelling machine we focus on has a stable processing capacity of 0.8-1.2 tons per hour (T/H). This capacity is ideal for small to medium-sized agricultural processing plants, seed cleaning facilities, or food factories that need to handle bulk sunflower seeds. Unlike low-capacity manual tools or unstable low-end machines, this equipment maintains consistent output without compromising dehulling quality—whether you’re processing raw sunflower seeds for edible use, oil extraction, or further processing.
The machine operates as part of a seamless 4-step line, ensuring every stage (from feeding to final separation) is automated and efficient. Here’s how each component works:
The process starts with an elevator—a vertical conveying device that automatically feeds raw sunflower seeds into the shelling system. This eliminates manual lifting and pouring, which not only reduces labor intensity but also prevents uneven feeding (a common cause of shelling inefficiency). The elevator’s design is tailored to sunflower seeds’ shape and size, avoiding seed damage during conveying and ensuring a steady flow to the next stage.
After feeding, seeds enter the shelling unit—the core part of the machine. This unit uses a gentle yet effective mechanical method (usually a combination of rolling and friction) to crack sunflower seed shells without breaking the inner kernels. The dehulling rate is over 95% (depending on seed variety), minimizing kernel loss. The shelling unit is adjustable to adapt to different sunflower seed sizes (e.g., large or small varieties), making it versatile for various raw materials.
Once shells are cracked, the mixture of kernels and shells moves to the vibration grader. This component uses high-frequency vibration and multi-layered screens to separate light shells from heavy kernels. The screens are designed with precise mesh sizes—shells (lighter and larger) are sifted to the top and discharged as waste, while kernels (denser and smaller) fall through to the next stage. This step achieves an initial separation rate of over 90%, laying the foundation for clean kernels.
To further improve kernel purity, the partially separated kernels go through a gravity table. This device uses air flow and slight tilting to separate any remaining small shell fragments or impurities from the kernels. Since shells and kernels have different densities, the gravity table’s air system lifts lighter shell bits, while kernels stay on the table surface and are collected as the final product. This step ensures the final kernels have a purity rate of over 98%, meeting food-grade or industrial standards.
High Efficiency: The 0.8-1.2T/H capacity and automated line cut processing time by 70% compared to manual work.
Low Kernel Damage: Gentle shelling and conveying design keep kernel integrity intact, reducing waste.
Easy Operation: All components are controlled via a simple panel, requiring minimal training for workers.
Low Maintenance: Durable materials (e.g., stainless steel for contact parts) resist wear, lowering maintenance costs.
