The traditional vibrating water draining machine adopts the spring and ordinary vibrating motor to achieve the vibration leaching and grading effect, but the disadvantage is that the noise is large and the vibration is not stable, and the grading effect is not satisfactory. Now, Ningbo Zhengguang Food Machinery Co., Ltd. has successfully developed rubber vibrating arm and imported vibration motor to solve the shortcomings of the traditional machines through efforts, realizing low noise, strong exciting force, stable material advancement and better grading effect.
