Have you ever wondered how the high - quality peanut oil on your dining table is produced? In this special report, we will take you on a journey through the entire production process of peanut oil, from shelling the peanuts to making edible peanut oil. This will not only deepen your understanding of this complex process but also enhance your trust in our brand that is committed to producing top - notch peanut oil.
The first step in peanut oil production is shelling the peanuts. Specialized shelling machines are used to separate the peanuts from their shells. These machines can process a large amount of peanuts efficiently. For example, a medium - sized shelling machine can shell up to 500 kilograms of peanuts per hour, ensuring a continuous supply of shelled peanuts for the subsequent production steps.
There are two main methods of extracting peanut oil: hot pressing and cold pressing. In hot pressing, the peanuts are first roasted at a high temperature, usually around 120 - 130 degrees Celsius. This process enhances the aroma of the oil but may also cause some loss of nutrients. The hot - pressed oil has a rich and strong flavor, which is favored by many consumers. On the other hand, cold pressing is carried out at a lower temperature, typically below 60 degrees Celsius. This method preserves more nutrients in the oil but may result in a lighter flavor. The oil cakes produced from hot pressing are often used as animal feed, while those from cold pressing can be further processed into peanut meal for human consumption in some cases.
After shelling, the peanuts need to be cleaned. Special cleaning machines are employed to remove impurities such as dirt, stones, and broken peanut shells. These machines use a combination of screening, air separation, and magnetic separation techniques. For instance, a screening machine can separate peanuts of different sizes, while an air separator can blow away lightweight impurities. This ensures that only clean and high - quality peanuts enter the next stage of production.
Baking temperature plays a crucial role in producing fragrant peanut oil. When the baking temperature is around 150 - 160 degrees Celsius, the peanuts develop a rich and intense aroma. For example, if the temperature is too low, the peanuts may not release enough aroma, resulting in a less fragrant oil. Conversely, if the temperature is too high, the peanuts may burn, affecting the quality of the oil.
Crushing the peanuts is an important step to increase the oil yield. By crushing the peanuts into smaller particles, the oil cells are broken, making it easier to extract the oil. After crushing, the oil yield can be increased by about 5 - 10% compared to uncrushed peanuts. Moreover, the peanut skins removed during the crushing process can be used as a raw material for producing natural antioxidants or as an ingredient in some health products.
During the oil extraction process, parameters such as pressure and temperature need to be precisely controlled. For example, the pressure is usually maintained at around 30 - 40 MPa to ensure efficient oil extraction. After the oil is extracted, the remaining oil cakes still contain a certain amount of oil. They can be further processed through solvent extraction to obtain more oil. The final oil cakes can be used as high - quality organic fertilizers or animal feed.
| Question | Answer |
|---|---|
| Is hot - pressed peanut oil healthier than cold - pressed peanut oil? | It depends on your needs. Cold - pressed peanut oil retains more nutrients, while hot - pressed peanut oil has a stronger flavor. You can choose according to your preference. |
| Can I use the peanut skins at home? | Yes, you can use them to make tea or add them to some health - related recipes. However, make sure to clean them thoroughly first. |
As we can see, the production of high - quality peanut oil is a professional and complex process. Our brand is dedicated to strictly controlling every step of the production process to ensure the production of the best - quality peanut oil. We hope that after learning about this process, you will have more trust in our brand and choose our peanut oil with confidence.
