At present, most countries in the world mainly use hot pressing for oil extraction, but in some areas cold pressing is mainly used. This is determined by the customs of each region. The cold pressing process of peanut oil press is different from hot pressing. Today, Benteng Machinery will tell you the cold pressing process of peanut oil press.
Cold pressing means that peanuts go directly to the inside of the oil press without the need for frying seeds. (The shelled peanuts can also be directly fed into the oil press.) Generally, cold pressing is processed in an environment below 60°C, and the nutrients are kept intact. The cold pressed peanut cake needs to enter the oil press again for a second pressing. The oil yield achieved after the second pressing is the peanut oil yield. The cold-pressed peanut oil needs to be filtered through a straight air filter (or a small oil filter). The filtered peanut oil can be used directly for cooking.
The main difference between cold pressing and hot pressing is that hot pressing needs to go through the process of fried seeds, while cold pressing does not have the process of fried seeds. But cold pressing needs to be pressed twice. Hot-squeeze it again.
Cold pressing avoids the adverse effects of traditional high-temperature oil pressing processing. The flavor and color of the oil are preserved in the cold-pressed refined oil, and the physiological substances in the oil are completely preserved (vitamins have anti-aging functions, sterols have skin-building effects and enhance human metabolism). The cold-pressed oil has the original flavor and is a healthy life. s Choice. And the cold-squeezed peanut oil does not smoke when cooking in the pan.
