How can the peanut roasting machine retain the nutrients of peanuts to the maximum extent?

Peanuts are a kind of nutritious food, which contains a lot of protein, unsaturated fatty acids, vitamins and minerals, and are a common food on people’s table. In the process of processing, how to retain the nutrients of peanuts to the maximum extent has become the focus of many producers. Peanut roasting machines (also known as nut roasters) are common equipment whose design and operation are crucial for preserving nutrients.

Proper temperature control is the key. During high temperature roasting, some nutrients in peanuts, such as vitamin E, may be destroyed by overheating. Therefore, the roaster should have accurate temperature control function. It is usually suggested to control the temperature between 120℃ and 160℃, which can not only ensure the peanut to be completely roasted, but also reduce the loss of nutrients.

Uniform heat distribution is very important. If the heating area of the roaster is uneven, some peanuts will be overheated, while others will be insufficiently heated. It not only affects the taste, but also may lead to uneven loss of nutrients. Therefore, the modern peanut roasting machine usually adopts a circulating hot air system to make the heat evenly distributed, thus ensuring that every peanut can be roasted under suitable conditions.

Time control is also a factor that cannot be ignored. Too long roasting can easily lead to the oxidation of oil in peanuts, thus affecting their nutritional value and taste. Generally speaking, according to the size and water content of peanuts, the roasting time should be controlled between 20 and 30 minutes. Advanced peanut roasters are usually equipped with automatic timers, which can accurately set the time and avoid human error.

In order to further retain the nutrients of peanuts, some modern roasters are also equipped with low oxygen environment function. This technology can reduce the oxidation effect of oxygen on peanut oil, thus better maintaining its natural flavor and nutritional value.

Finally, different types of peanuts—such as high-oil or low-oil varieties—require customized roasting profiles. Versatile commercial nut roasters allow for tailored temperature and time settings to match specific nut characteristics. Regardless of the raw materials used, this flexibility helps producers optimize nutrient retention.

To sum up, many factors need to be considered comprehensively in order to keep the nutrients of peanuts to the maximum extent in the peanut roasting machine. By optimizing these links, consumers can not only enjoy healthier and more delicious peanut products, but also improve the competitiveness of processing enterprises.
