[0002] Peanut is a common agricultural economic crop. Due to its low requirements for the growing environment, peanut fruits contain protein, fat, carbohydrates, vitamin A, vitamin B6, vitamin E, vitamin K, as well as minerals such as calcium, phosphorus, and iron. In addition to being eaten directly, it can also be processed into peanut oil. Peanut oil is light yellow and transparent, with a clear color, fragrant smell, and delicious taste. It is a relatively easy to digest edible oil.

[0003] The existing technology has the following problems:

6. A method for increasing the squalene content in peanut oil by using the baking device according to any one of claims 1 to 5, characterized in that: The baking method for increasing the squalene content in peanut oil comprises the following steps: Step 1: Preparation of peanut raw materials: You need to prepare fresh peanuts, and the peanuts should be purple-skinned peanuts; Step 2: Peanut cleaning: Rinse the raw peanuts with clean water to remove impurities and sand on the surface, and then dry the peanuts; Step 3: Screening of peanuts: The dried peanuts are screened by a screening machine, and peanuts of different sizes are stored separately; Step 4: Peanut roasting: pre-treat the peanuts in hot water, remove the peanut skins, and control the moisture content of the peanuts to 20%-30%. Then, roast the peanuts of different sizes in batches at 170℃-180℃ for 20-30 minutes, so that the moisture content of the peanuts reaches 11.49%. Then, use cold air to reduce the temperature of the peanuts to below 40℃. Step 5: Peanut pressing: Take out the roasted peanuts and quickly grind them into powder using a grinder to ensure the fineness of the peanut powder. Put the ground peanut powder into an oil press to extract the oil, and separate the oil from the peanut powder by applying pressure.
