Cold-Press vs Hot-Press: Optimizing Peanut Oil Yield & Quality with Automated Production Lines

This technical brief examines QIE Group’s fully automated peanut oil production line, focusing on how integrated cold-press and hot-press workflows maximize oil yield and quality across variable peanut raw-material conditions. It explains the process principles behind cold pressing (minimal heat, higher nutritional retention) and hot pressing (pre-treatment and thermal extraction for higher recovery), and outlines decision criteria—moisture, kernel size, and free fatty acid levels—that determine optimal process selection. The article highlights the high-efficiency refining module and 304 stainless-steel construction that ensure food-safety, corrosion resistance and environmental compliance, and compares energy-consumption and yield trade-offs between the two approaches. Practical value is reinforced with Southeast Asia, Africa and Middle East case studies, process diagrams, key process-parameter tables and an energy-consumption comparison chart. The paper also summarizes international certifications, export-compliance considerations and QIE Group’s after-sales service model to support procurement decisions and overseas operations.
