The peanut sieving machine is a key piece of equipment in the peanut processing line, responsible for separating peanuts of different sizes and removing impurities such as stones, soil, or broken shells. Its screening accuracy directly determines the efficiency, purity, and final quality of the processed peanuts.

In industrial peanut processing, accurate screening ensures consistent product grading and higher market value. There are many factors that affect the screening accuracy of peanut sieving machine. The following are some key points:

First, the design and quality of screen plays a decisive role in screening accuracy. The pore size and shape of the screen need to match the size and shape of peanuts. If the pore of the screen is too large, small particles or impurities may not be effectively removed; If the pore size is too small, it may affect the passing rate of peanuts and reduce the screening efficiency. Therefore, it is very important to choose the appropriate screen material and design.

Second, the vibration frequency and intensity of the machine are also important factors affecting the screening accuracy. Peanut sieving machine usually separates peanuts from impurities by vibration. Too high or too low vibration frequency will affect the screening effect. Proper vibration setting can ensure the uniform distribution of peanuts on the screen surface and effectively remove impurities.

Besides, the moisture content and shape of peanuts will also affect the screening accuracy. If peanuts are too dry or wet, it may lead to particle adhesion or poor sliding during the screening process, thus reducing the screening effect. In addition, the irregular shape of peanuts may also increase the difficulty of screening, and the equipment parameters need to be adjusted according to the actual situation.

Moreover, the maintenance condition of the machine can not be ignored. After long-term use, the screen may be blocked or damaged, and the vibrating device may lose its best working condition, which will affect the screening accuracy. Therefore, regular inspection and maintenance of equipment is an important measure to ensure its stable performance.

Last, the skill level of operators also has a certain influence on the screening accuracy. Skilled operators can flexibly adjust machine parameters according to the characteristics of different batches of peanuts to improve screening efficiency and accuracy.

In summary, the screening accuracy of a peanut sieving machine is determined by a combination of equipment design, vibration parameters, peanut characteristics, maintenance quality, and operator expertise. By optimizing these factors and integrating the sieving machine within a complete peanut processing line, manufacturers can significantly enhance product consistency, yield, and market competitiveness.

Whether used for peanut cleaning, grading, or pre-processing before oil extraction, a well-designed peanut sieving machine ensures stable performance, high throughput, and excellent product quality.
