Gaofu Anti-blocking Flour Rotary Vibrating Sieve Food Powder Screening Device

Gaofu Anti-blocking Flour Rotary Vibrating Sieve Food Powder Screening Device

Food-Grade Screening, Safeguarding the Quality of Every Grain of Flour
In the food processing industry, flour screening is a critical step in ensuring product quality. Xinxiang Gaofu Machinery Co., Ltd. has been deeply engaged in the screening equipment field for many years. Our flour-dedicated rotary vibrating sieve is specifically designed for food powder screening applications, committed to providing stable and reliable screening solutions for flour production enterprises.

Five Game-Changing Innovations That Redefine Food Powder Screening

  • Anti-blocking Design for Sustained Throughput
Equipped with optional bouncing balls or an ultrasonic anti-blinding system, the sieve effectively prevents mesh clogging—especially critical for cohesive and adsorptive fine powders such as flour. Screening precision ranges from 2 to 200 mesh (approximately 0.075mm to 10mm).
  • Three-Dimensional Vibration Motion for Uniform Screening
Driven by a vertical vibration motor with eccentric weights mounted at both ends, rotational motion is converted into horizontal, vertical, and inclined three-dimensional movement. This ensures comprehensive material distribution across the screen surface, significantly improving both efficiency and accuracy.
  • Fully Enclosed, Food-Grade Construction
The fully sealed design prevents powder dispersion and liquid leakage, meeting food production hygiene standards. All product-contact surfaces are made from 304/316 stainless steel with food-grade silicone seals, finished with internal and external mirror polishing for easy cleaning and zero contamination risk.
  • Quick Screen Change for Minimal Downtime

The proprietary screen frame design enables screen replacement in just 3–5 minutes by a single operator, drastically reducing production interruptions. The compact footprint and mobility further enhance operational flexibility.

  • Multi-Layer Configuration for Simultaneous Grading

With 1 to 5 screen layers available, the unit completes multi-stage classification in a single pass, streamlining production workflows.

Screening Objectives

    • Impurity Removal & Filtration: Eliminate foreign matter such as thread, metal debris, and lumps from flour, starch, and other raw materials to ensure food safety;


    • Particle Size Classification: Separate powders into specified mesh sizes to meet diverse product formulation requirements;


    • Slurry Filtration: Perform solid-liquid separation for food slurries, including juice clarification and soybean milk residue removal.
