The 6YL-80A automatic sunflower seed oil press is an advanced, compact, and versatile oil extraction machine designed for small to medium-sized oil processing plants. This robust oil press efficiently extracts high-quality edible oil from over 20 types of oilseeds, including sunflower seeds, peanuts, soybeans, flaxseeds, rapeseeds, sesame seeds, and cottonseeds. Engineered for continuous operation, this screw oil press combines high productivity with excellent oil yield, making it ideal for commercial and industrial applications.
Key Features and Benefits of the 6YL-80A Seed Oil Press
1. Robust Construction and Advanced Design
Constructed from premium carbon steel and stainless steel, this seed oil press ensures long-lasting durability and corrosion resistance. Its ergonomic design enables easy operation with minimal maintenance requirements.
2. Flexible Pressing Options
The equipment supports both hot and cold pressing methods to accommodate diverse oilseed processing requirements. Its four-stage pressing system combined with vacuum filtration produces clear, aromatic, and pure oils suitable for direct consumption or bottling.
3. High Efficiency & Energy Savings
Compared to traditional oil expellers, the 6YL-80A sunflower oil press achieves up to 60% electricity savings and 40% labor cost reduction while maintaining high oil extraction rates. Its broad applicability makes it a cost-effective choice for processing diverse oilseeds.
4. Ideal for Multiple Oil Seeds
From sunflower seed oil extraction to processing peanuts, soybeans, and rapeseed, this fully automatic oil press is widely used in medium to large-scale edible oil plants, significantly boosting production capacity and profitability.
Should Sunflower Seeds Be Shelled Before Pressing?
Sunflower seeds contain 22% to 50% oil, depending on the variety. “Oil-type sunflowers,” specifically bred for oil extraction, can reach up to 50% oil content. While shelled seeds can be pressed, hulling before processing is strongly recommended for the following reasons:
1. Reduced Wax Content
Sunflower seed hulls contain 0.4% to 10.7% wax, accounting for approximately 75% of the total wax in sunflower seeds. Crushing with hulls increases wax content in crude oil (0.02% to 0.35%), complicating the oil refining process. Shelling reduces wax content to 0.011%–0.015%, ensuring superior oil clarity and stability.
2. Minimizing Oil Loss
Sunflower seed hulls absorb significant amounts of oil, typically twice that of the meal. For instance, if the meal residual oil rate is 10%–13%, the oil content in the hulls can reach 24%–28%. Hull removal improves oil recovery and reduces waste.
3. The Shell Contains 60% of Crude Fiber
Shells contain about 60% crude fiber, which can hinder feeding, reduce oil press capacity, and accelerate wear on the sunflower seed oil expeller. Additionally, sunflower kernels have a soft texture and low fiber content; excessive moisture or seed hulls can cause blockages. Proper hulling ensures smoother machine operation and higher-quality sunflower oil.
Optimizing Sunflower Oil Production
For best results when using a hydraulic oil press or screw oil press, ensure sunflower seeds are properly cleaned, dried (moisture controlled at 8%–10%), and ideally hulled. This enhances oil flowability, protects equipment, and produces cleaner, market-standard edible oil.
