Have you ever wondered how the seemingly ordinary crushing process can bring about a miraculous increase in the yield of peanut oil? In this article, we'll embark on a journey to explore the exquisite production technology of peanut oil, with a special focus on the amazing role of the crushing stage.
There are two main methods for producing peanut oil: hot - pressing and cold - pressing. Hot - pressing involves heating peanuts to a certain temperature before extraction. This method can extract a relatively high amount of oil, with an average yield of about 40% - 45%. The oil produced by hot - pressing has a rich and intense flavor, which is very popular among consumers who love a strong - tasting oil.
Cold - pressing, on the other hand, is carried out at a lower temperature. It retains more of the nutrients in peanuts, such as vitamins and antioxidants. However, the oil yield is relatively lower, usually around 30% - 35%. The cold - pressed peanut oil has a lighter flavor, which is suitable for those who prefer a more natural and mild taste.
Before the pressing process, peanuts need to be thoroughly cleaned. Special peanut cleaning machines are used in this stage. These machines can remove impurities such as dirt, stones, and broken peanuts. For example, a high - efficiency peanut cleaning machine can process about 500 - 1000 kilograms of peanuts per hour, ensuring that only clean and high - quality peanuts enter the next production stage.
Baking is an important step in peanut oil production. Different baking temperatures can have a significant impact on the flavor of the oil. When the baking temperature is around 120 - 130°C, the peanuts release a light and delicate nutty flavor, which is transferred to the oil. If the temperature is increased to 150 - 160°C, the oil will have a more intense and roasted flavor. However, if the temperature is too high, it may cause some nutrients in the peanuts to be damaged.
The crushing process is the key to improving the oil yield. During crushing, the cell walls of peanuts are broken, allowing the oil to be more easily released. Through advanced crushing technology, the oil yield can be increased by about 5% - 10%. For example, if the original oil yield of a certain batch of peanuts is 40%, after proper crushing, it can reach 45% or even higher.
Our brand is committed to using the most advanced crushing technology to ensure the highest oil yield while maintaining the quality of the oil. Our professional R & D team has continuously optimized the crushing process to achieve the best balance between yield and quality.
After the oil is extracted, there are still oil cakes left. These oil cakes can be further processed. They can be used as high - quality animal feed because they still contain a certain amount of protein and other nutrients. In addition, they can also be used in the production of organic fertilizers, which is an environmentally friendly and resource - saving way of utilization.
As we can see, the production of peanut oil is a professional and complex process. Our brand, with its pursuit of professional production technology, is dedicated to providing consumers with high - quality peanut oil. We hope that through this article, you can have a deeper understanding of peanut oil production and gain more trust in our brand.
