You’re not alone if your peanut oil tastes bland or has a shorter shelf life than expected. Many small-scale oil mill owners overlook one critical factor: temperature control during pressing. In fact, studies show that when press temperatures exceed 55°C, up to 40% of vitamin E can be lost — and that’s before you even consider plant sterols or flavor compounds.
Unlike traditional high-heat extraction methods, low-temperature cold pressing (ideally under 45°C) preserves the natural nutrients in peanuts. A real-world case from a family-run mill in Henan province showed an 8% increase in yield after adjusting their screw press settings — and customers reported clearer oil with better aroma and longer storage stability.
Modern automated screw cold presses offer precision temperature control, which is essential for maintaining oil integrity. One user noted they reduced manual adjustments by 70% while increasing daily production capacity by 25%. No more guesswork — just stable, repeatable performance.
If you're serious about improving both yield and product value, it's time to rethink how you handle heat. The difference between a good batch and a great one isn’t just skill — it’s science, consistency, and smart tools.
Discover how our industrial-grade screw cold press delivers precise temperature control, higher yields, and less waste — all designed for small mills like yours.
