Have you ever wondered how high - quality peanut oil is born? In the world of peanut oil production, there are two main processes: hot - pressed and cold - pressed. Today, let's embark on a journey to explore the mysteries behind these two processes.
The first step in making peanut oil is to remove the shells from the peanuts. Specialized shelling machines are used to crack the shells and separate the peanuts. This is a crucial initial step as clean, shelled peanuts are the foundation for high - quality oil production. Our brand uses advanced shelling equipment that can handle large volumes of peanuts with high efficiency, ensuring that the peanuts are not damaged during the shelling process.
Hot - Pressed Process: The hot - pressed process involves several steps. First, the peanuts are cleaned to remove any impurities. Then, they are crushed into smaller pieces. After that, the crushed peanuts are steamed at a high temperature (usually around 120 - 130°C). Finally, the steamed peanuts are sent to the oil press. This process generally has a higher oil yield, usually around 40% - 45%. The hot - pressed peanut oil has a rich and strong flavor, which is very popular among consumers who like a more intense taste. The oil cake left after hot - pressing can be used as high - quality animal feed.
Cold - Pressed Process: In the cold - pressed process, the peanuts are also cleaned first. Then, they go through a conditioning step to adjust their moisture content. The cold - pressing is carried out at a relatively low temperature (below 60°C). The oil yield of the cold - pressed process is slightly lower, around 35% - 40%. However, the cold - pressed peanut oil retains more nutrients, such as vitamins and antioxidants. The oil has a lighter flavor and is more suitable for those who prefer a milder taste. The oil cake from cold - pressing can be used in the production of fertilizers.
| Process | Oil Yield | Product Characteristics | Oil Cake Use |
|---|---|---|---|
| Hot - Pressed | 40% - 45% | Rich and strong flavor | Animal feed |
| Cold - Pressed | 35% - 40% | Lighter flavor, more nutrients | Fertilizer production |
Peanut cleaning is an important part of the production process. Our brand uses advanced peanut cleaning machines, including vibrating screens and air separators. The vibrating screen can separate peanuts of different sizes, while the air separator can remove dust, stones, and other light impurities. These machines ensure that the peanuts entering the next stage are clean and of high quality.
Baking temperature plays a vital role in producing aromatic peanut oil. When the baking temperature is around 150 - 160°C, the Maillard reaction occurs in the peanuts, which produces a rich and pleasant aroma. However, if the temperature is too high, it may lead to the loss of some nutrients and affect the quality of the oil. Our brand has precisely controlled the baking temperature through years of research and experience to ensure the best flavor and quality of the peanut oil.
The crushing step breaks the peanuts into smaller pieces, increasing the surface area of the peanuts. This allows the oil to be more easily released during the pressing process. Our brand uses high - quality crushing equipment that can crush the peanuts evenly, effectively improving the oil yield.
For both hot - pressed and cold - pressed processes, proper parameter setting is crucial. For example, in the hot - pressing process, the pressure of the oil press and the duration of steaming need to be precisely controlled. After pressing, the oil cake is further processed. As mentioned before, it can be used as animal feed or for fertilizer production, achieving comprehensive utilization.
Now, here's a question for you: Which process do you think is more suitable for your daily cooking, hot - pressed or cold - pressed? If you're still unsure, don't worry.
