Selection Guide

Material Comparison

Tips to Avoid Pitfalls: Low-quality 201 stainless steel on the market is prone to rust and leaching heavy metals; its use for storing cooking oil is strictly prohibited. When purchasing, look for food-grade certification labels and specific material stamps on the container. Avoid unqualified, low-quality containers to ensure the safety of your oil storage.

Maintenance and Care

Pre-treatment (For New Tanks)

• Use a 3.5% citric acid solution and circulate at 85°C for 30 minutes to neutralize alkaline residues and promote the formation of a passivation film, increasing density by 27%.
• Then rinse with pure water until neutral (pH 6.5–7.5) and wipe the inner walls dry before storing oil. Business Recommendation: Have our technicians provide on-site guidance before first use.

Routine Cleaning

• Prohibited: Steel wool, chlorine-based cleaners, hydrochloric acid-based products (these will damage the passivation film and cause chloride ion deposition).
• Correct Procedure: Scrub the inner walls with a neutral detergent and a soft sponge, then rinse three times with pure water (soaking for 5 minutes each time).
• Frequency: Cleaning is mandatory when changing oil types; Clean and drain at least once a month when storing the same type of oil long-term.

Regular Monitoring

• Monthly: Use a flashlight to inspect the inner walls for rust spots and check the condition of the sealing rings.
• Quarterly: Take samples to test the acid value (safe limit ≤ 0.5 mg/kg) and peroxide value of the oil.
• Commercial Smart Module (Optional): Monitors six parameters online—temperature, humidity, liquid level, metal leaching, and acid value trends—with automatic alerts for exceedances.

Why Choose Us?

• Our stainless steel tanks are constructed from high-quality, thick-gauge stainless steel, offering excellent corrosion resistance and ensuring safety and reliability.
• The inner walls of our stainless steel tanks’ manholes are fitted with food-grade rubber gaskets that provide a tight, airtight seal, preventing any contamination.
• Our stainless steel oil storage tanks are equipped with dedicated level gauge valves that operate smoothly and responsively. No tools are required, and oil levels can be read instantly.
• We use argon arc welding with a fish-scale pattern, resulting in uniform, dense welds that ensure the quality of edible oil over the long term.

We offer not only a variety of stainless steel edible oil storage tanks but also machinery for edible oil production, such as oil presses. If you require oil extraction or storage equipment, please contact us. We specialize in customization to meet your diverse needs.
