stainless steel edible cooking oil storage tanks

Core Specifications & Features

1. Material Selection

◦ Main body: Food-grade SUS304 stainless steel for general edible oils; SUS316L stainless steel for high-acid oils (e.g., linseed oil, perilla oil) to enhance corrosion resistance.

◦ Inner wall: Mirror-polished (Ra ≤ 0.4 μm) for easy cleaning and to avoid oil residue adhesion; outer wall can be coated with anti-corrosion paint or wrapped with insulation materials.

2. Structural Design

◦ Closed structure: Equipped with a sealed manway and a 0.22 μm air filter on the breathing port to prevent dust, bacteria, and moisture from entering, which avoids oil rancidity caused by contact with air.

◦ Jacket or coil insulation: Some models have a jacket/coil structure for temperature control (storage temperature recommended at 15–25°C) to reduce the impact of high temperature on oil quality; nitrogen blanketing systems are optional for long-term storage of premium oils, isolating oxygen completely.

◦ Bottom design: Sloped bottom or conical bottom for complete discharge of oil, with a sanitary ball valve or butterfly valve at the outlet for smooth, residue-free flow.

3. Key Accessories

◦ Level gauge: Float-type or radar level gauge for real-time monitoring of oil volume, supporting automatic alarm for high/low levels.

◦ Sampling valve: Installed at the lower part of the tank for regular oil quality testing (acidity value, peroxide value).

◦ Cleaning ports: CIP cleaning ball for automated cleaning, eliminating the need for manual entry and reducing contamination risks.

Application Scenarios

Ideal for oil refineries, edible oil processing plants, and food manufacturing enterprises, suitable for both bulk storage of raw oil and temporary storage of finished oil before filling.
