Special report

This article explores the successful application and optimization of deacidification and deodorization technologies in Pengyuan Group’s proprietary soybean oil refining equipment. It details key aspects such as selection of deacidification agents, control of neutralization reaction kinetics, and critical parameters in deodorization processes—integrated with modern vacuum deodorization techniques to deliver a comprehensive processing solution. Through real-world case studies and technical analysis, this piece demonstrates how overseas soybean oil processors can enhance deacidification efficiency, reduce off-flavors, and ensure consistent oil quality—strengthening product competitiveness and brand reputation in global markets.

Optimizing Soybean Oil Refining: A Proven Path to Global Competitiveness

In today’s competitive global market, soybean oil processors must go beyond basic refining—they need intelligent, efficient, and scalable solutions that deliver consistent quality and meet international standards. At Penguin Group, we’ve helped multiple overseas refineries improve their de-gumming and deodorization processes through targeted technical upgrades and process integration.

Why De-Gumming & Deodorization Matter More Than Ever

According to a 2023 report by the International Oleochemical Association, up to 35% of exported soybean oil fails to meet premium-grade specifications due to residual gum content or off-odors—often stemming from suboptimal de-gumming agents or inconsistent temperature control during deodorization.

Process Step	Key Parameter	Recommended Range
De-Gumming Agent Selection	Water vs. Phosphoric Acid	pH 4.5–5.5 for water-based systems
Neutralization Time	Reaction Kinetics Control	25–35 min at 65°C
Deodorization Temp	Vacuum + Steam Flow Rate	240–250°C under 0.01–0.02 mbar vacuum

By focusing on these critical parameters—and integrating them into modular, automated systems—we’ve seen clients reduce odor complaints by over 70%, increase yield by up to 3%, and cut energy consumption by 12% in just six months.

Real Results from Real Clients

A leading processor in Brazil upgraded their de-gumming unit using Penguin Group’s patented multi-stage mixer and real-time pH monitoring system. Within two months, they achieved:

Reduction in phospholipid residue from 120 ppm to ≤20 ppm
Elimination of “raw oil” smell in final product
Improved shelf life from 6 to 12 months (under ISO 22000 conditions)

What made the difference? It wasn’t just better equipment—it was smarter process design, local support, and continuous optimization based on actual production data.

The trend toward automation isn’t optional anymore—it’s essential. Modular designs allow facilities to scale without redesigning entire lines. And when issues arise, having a local engineering team means downtime drops from days to hours.

Whether you're operating in Southeast Asia, the Middle East, or Latin America, your soybean oil must compete—not just domestically, but globally. That starts with mastering the fundamentals: clean de-gumming, precise neutralization, and controlled deodorization.
