Soybean Storage Before Soya Oil Processing
In the modern agricultural system, storing grains and oilseeds is a crucial aspect to ensure the food supply chain. Soybeans, as a versatile crop, provide abundant proteins and oils for human consumption and are widely cultivated in the agricultural sector. However, due to their high oil and protein content, soybean storage before extracting soybean oil will face unique challenges. (Related Aritcle: How to extract soybean oil?)

Three Key Details in Soybean Storage of Soya Oil Processing Business
To ensure optimal conditions for soybeans during storage, agricultural producers and soybean oil owners need to pay attention to several key details: thorough drying, timely ventilation, and low-temperature storage. These three key details constitute crucial elements in soybean storage, determining the quality and stability of soybean oil.
Soybean Harvest & Drying Details
-
1. Thorough drying, moisture content below 12.5%
After soybean threshing, it is essential to quickly air-dry to reduce moisture for safe storage. The moisture content of stored soybeans should not exceed 12.5% for long-term storage to prevent mold growth.
-
2. Ventilation and cooling 3-4 weeks after soybeans are stored
| Moisture content % | Minimum airflow rate (cubic feet per minute/bushel) |
|---|---|
| 18 to 20 | 3.0 |
| 15 to 18 | 2.0 |
| 13 to 15 | 1.0 |
| 11 to 13 | 0.5 |
-
3. Low-temperature storage at 40-60℉
In the harsh winter season, frozen soybeans are used in the soybean oil production process, with storage temperatures controlled between 40-60℉. This temperature range ensures optimal freshness, slows down lipid oxidation, and enhances product stability. Experimental data shows that this method reduces pest infestation by over 80% and slows down lipid oxidation by nearly 50%, ensuring the quality and taste of soybean oil.
Soybean Storage Techniques: Tailored for Different Scales of Soybean Oil Mills
From small-scale ordinary farmers to large-scale commercial oil mills, soybean storage methods vary with scale. Next, we will explore soybean storage techniques for different scales, providing comprehensive guidance for soybean oil producers and helping them achieve optimal storage results at different scales.
For Small-Scale Soybean Oil Workshops [Home Use]
Soya Storage for Farmer Use
-
Air drying and moisture reduction: After soybean harvesting, ordinary farmers must ensure thorough air-drying to reduce moisture content. The moisture level should be below 13% to prevent mold growth. During this stage, simple air-drying equipment such as drying racks or open-air spaces can be used.
-
Sealed storage in plastic bags: Small-scale soybean storage can adopt sealed plastic bags to reduce air circulation, preventing moisture and pest intrusion. Sealed storage helps maintain soybean quality and extends storage life.
-
Avoid high temperatures and direct sunlight: The storage location for soybeans should be well-ventilated, shaded to avoid direct sunlight, preventing the adverse effects of high temperatures and maintaining freshness.
-
Regular inspections: Regularly inspect stored soybeans for signs of mold, pest infestation, etc., and take timely measures to ensure storage quality. In humid and rainy environments, soybeans should be consumed or sold within a year to avoid deterioration.
For Large-Scale Commercial Soybean Oil Production Plants [Industry Investors]

-
Precision control of moisture content: Large-scale manufacturers control moisture content precisely during soybean acquisition, ensuring it remains within a controllable range, usually below 10%. Advanced drying equipment and meticulous testing procedures help maintain soybeans' moisture within optimal storage standards.
-
Large storage facilities: Commercial soybean oil production plants typically have large storage facilities such as warehouses and automated conveying systems to enhance storage efficiency and reduce labor costs.
-
Temperature and humidity control: Large manufacturers use advanced temperature and humidity control systems to ensure the soybean storage environment is optimal. Particularly in large-scale production, controlling temperature and humidity becomes crucial.
-
Regular testing and monitoring: Commercial plants use periodic soybean sample testing and real-time monitoring systems to detect and address potential issues promptly, ensuring stored soybeans consistently meet production standards, enhancing product stability and quality.
