In the peanut processing process, peanut sieving machine is a commonly used agricultural product grading equipment. Its main function is to classify peanuts according to their size, shape or other characteristics to meet different uses or market demands. However, the moisture content of peanuts will directly affect the physical properties, thus interfering with the grading effect.

Moisture content alters the physical properties of peanuts. Peanuts with high moisture content are more prone to sticking, which can prevent smooth flow through the peanut sieving machine and affect grading accuracy. Furthermore, peanuts with excessive moisture content can increase their weight, making it difficult for the screening mechanism to accurately distinguish between different grades.

Low moisture content can also cause problems. Dry peanuts are brittle, especially during the mechanical grading process, which can produce a large amount of debris. This debris not only affects the proper functioning of the peanut sieving machine but can also be mixed into different grades of peanuts, reducing the purity and quality of the final product.

To ensure effective grading, the moisture content of peanuts must be kept within an appropriate range. Generally speaking, the optimal moisture content for peanuts is between 8% and 12%. Within this range, the peanuts are neither too moist, causing them to stick together, nor too dry, causing them to become brittle. Proper drying or humidification can effectively optimize the physical condition of the peanuts, thereby improving the efficiency of the peanut sieving machine

In addition, during actual operation, the performance of the peanut sieving machine and the condition of the screens must be regularly checked to ensure that the equipment can accommodate peanuts of varying moisture contents. At the same time, combining with other auxiliary equipment, such as air separators or vibrating screens, can further improve the classification effect.

In short, the moisture content of peanuts is an important factor affecting the grading effect. Proper moisture control not only improves production efficiency but also ensures product quality, laying a solid foundation for subsequent processing. Therefore, in practice, peanut moisture should be scientifically managed based on specific circumstances to optimize the grading performance of peanut sieving machine.
