To calculate how many tons of peanut oil can be extracted from 10 tons of peanuts, you can use formula of oil output: (oil output rate - residual oil rate) * processing capacity. In two conditions, if only the pressing method is used, the oil content of peanuts is between 40-55%, and the residual oil rate is 6-7%, so it can be calculated that 10 tons of peanuts can press 3.3-4.9 tons of peanut oil. If the solvent extraction method is used, the solvent leaching residual oil rate is 1%, and 3.9-5.4 tons of peanut oil can be obtained. Of course, the above calculation formula is in an ideal state to calculate how many tons of peanut oil can be extracted from 10 tons of peanuts, but in fact, the amount of oil extracted by peanuts is also affected by multiple factors.

Mechanical Pressing: A Traditional & Natural Approach

Mechanical pressing, also known as cold pressing or expeller pressing, is a natural method of extracting peanut oil. This process involves crushing the peanuts under high pressure to release the oil. Typically, mechanical pressing can extract 40-55% of the oil content from peanuts, depending on factors such as peanut variety, moisture content, and pressing technique. Peanuts in the harvest, transportation and storage process will contain some impurities, such as sediment, peanut shell, stone, metal substances, etc., these impurities mixed in the peanut seed will affect the machine operation, thus affecting the peanut oil efficiency and actual oil output. Large cooking oil processing plants are generally equipped with pretreatment equipment to remove these impurities, and small oil mills do not have the ability to purchase a whole peanut oil processing line, often not carefully cleaned, but choose direct pressing, the oil yield will be reduced accordingly. For instance, if you extract peanut oil from 10 tons of peanuts, mechanical pressing alone can yield approximately 3.3-4.9 tons of peanut oil. This method is highly preferred for producing high-quality, chemical-free, and nutrient-rich peanut oil.

Solvent Extraction: Maximizing Oil Recovery

To further increase the oil yield, many producers turn to solvent extraction, a process that involves using a food-grade solvent, usually n-hexane, to dissolve and extract the remaining oil from the peanut cake left after mechanical pressing. This method can recover up to 99% of the total oil content in peanuts, significantly boosting efficiency.

By applying solvent extraction after mechanical pressing, you can extract 3.9-5.4 tons of peanut oil from 10 tons of peanuts ultimately, ensuring almost complete oil recovery. This technique is widely used in large-scale commercial production to maximize profitability.

Direct solvent extraction machines

How many tons of peanut oil can you extract from 10 tons of peanuts? can be directly calculated by the formula, and the theoretical value range can be obtained. Both mechanical pressing and solvent extraction have their unique advantages. If you prioritize pure, chemical-free peanut oil, mechanical pressing is the best choice. However, if your goal is to extract the maximum possible oil yield and increase profitability, combining pressing with solvent extraction is the most efficient approach.

No matter which method you choose, extracting peanut oil from 10 tons of peanuts with high quality equipment and advanced technology will ensure you get the best yield and highest quality peanut oil for your customers.
