In the process of food processing and grinding, square plansifter and circular screen are two common screening equipments. They have certain differences in structure, screening method and scope of application. This article will provide an in-depth comparison of the characteristics and applications of square plansifters and round screens in food processing and grinding to help you choose the screening equipment that suits your needs.

 1. Structural comparison:

The screen frame of the square plansifter is square or rectangular, and the screen mesh covers the bottom of the screen frame. The vibration mechanism causes the screen frame and screen mesh to vibrate to achieve screening of granular materials. The screen frame of the circular screen is circular, and the screen mesh is arranged in an annular shape on the screen frame. The vibration mechanism of the screen frame and screen mesh is also achieved through a vibration mechanism.

 2. Comparison of screening methods:

The square plansifter is mainly used for primary screening and coarse screening in food processing and grinding, and is suitable for coarse screening of raw materials with larger particles. The circular screen is often used for fine screening and fine powder classification processes, which can achieve a finer screening effect.

 3. Comparison of applicable scope:

The square plansifter is suitable for preliminary screening and coarse screening of food processing raw materials with larger particles, such as preliminary screening of wheat, rice and other grains. The circular sieve is more suitable for fine screening and classification of powders and fine powders, such as flour, starch and other fine powders.

 4. Comparison of screening efficiency and accuracy:

Because the screen layout of the square plansifter is relatively simple, the screening efficiency is generally slightly lower than that of the circular screen. The circular screen has a more uniform screen layout, higher screening efficiency and precision, and is suitable for fine screening of powder.
