Factors Affecting the Production of Peanut Oil

The oil yield directly impacts the profitability and long-term development of enterprises. The oil yield is considered one of the standards for evaluating the performance of a set of peanut oil processing equipment. For peanut oil processing equipment, its quality, performance, processing technology, and operating specifications can directly or indirectly affect the oil yield. Let's take a look at the main factors affecting the oil yield of peanut oil.

Factors Affecting Peanut Oil Yield:

Quality and Performance of the Equipment

High-quality, high-performance, and well-configured peanut oil processing equipment can fully press peanuts, reduce oil loss, and thus obtain more peanut oil, improving the oil yield. Many oil press manufacturers are continuously upgrading the press chamber of oil presses, significantly enhancing pressing efficiency and oil yield.

Processing Technology:

Shelling, Steaming, Frying, Pre-pressing, and Extraction

Besides the quality and performance of the equipment, operations such as shelling, steaming, and frying peanuts before pressing can also significantly improve the oil yield.

Shelling: The oil in peanuts is mainly concentrated in the kernels, with very little oil in the shells. Pressing peanuts with shells not only yields less oil but also causes the shells to absorb oil, reducing the oil yield. Shelling helps increase the oil yield and the reasonable production capacity of the equipment.

Steaming and Frying: "Three parts pressing, seven parts frying" indicates that steaming and frying peanuts before pressing is a major method to improve oil yield. Steaming and frying break the internal cells of peanuts, denature proteins, gather oil, and reduce the viscosity and surface tension of the oil, allowing more oil to be extracted.

Pre-pressing and Extraction: Peanuts are high-oil crops. After a single pressing, the residual oil rate in the cake is relatively high. Using the pre-pressing and extraction method, the residual oil in the pre-pressed cake can be extracted by soaking it in a solvent. Thus, after shelling, steaming, frying, and pre-pressing extraction, the oil yield of peanuts is improved.

Standardized Operation of Equipment

Regularly cleaning the oil seams of the pressing bars and rings, reasonably controlling the feeding speed, timely adjusting the feeding amount, and raising the temperature inside the press chamber can all create good pressing conditions. This ensures normal oil output while maintaining a high oil yield for peanut oil
