Adhering to strict food safety standards, it features full food-grade construction, dust-free enclosed design and gentle conveying, perfectly matching flour sieving, mixing, packaging and other production links, realizing clean, low-loss and efficient material transfer for food processing lines of all scales.

Core Advantages

1. Food-Grade Hygienic Construction: All material contact parts are made of AISI 304/316L stainless steel with polished, crevice-free and easy-to-clean surfaces, complying with FDA, 3-A and BISSC food safety standards. No dead corners for material residue, avoiding cross-contamination and meeting the strictest hygiene requirements of flour and food processing.
2. Gentle Conveying & Low Material Loss: Adopts food-grade PU/PVC anti-stick conveyor belt with smooth surface, minimizing flour adhesion and raw material loss (≤0.2%). The soft conveying mode prevents flour agglomeration and particle breakage, ensuring the original quality and particle size distribution of flour.
3. Dust-Free & Sealed Operation: Fully enclosed cover design with dust-proof feeding/discharging hoppers effectively prevents flour dust leakage, moisture absorption and secondary pollution, maintaining a clean workshop environment and complying with industrial environmental protection and occupational health standards.
4. Smooth & Energy-Efficient Operation: Optimized roller and belt tension structure ensures stable, slip-free and low-noise (≤70dB) conveying; energy-efficient motor with VFD enables stepless speed adjustment (0.5-3m/s), matching different production line speeds and reducing energy consumption by 20% compared with conventional models.
5. Easy Cleaning & Maintenance: Tool-free quick disassembly of belt, cover and hopper; all components are designed for CIP (Clean-in-Place) compatibility, facilitating daily cleaning and sterilization. Fewer moving parts with sealed bearings reduce maintenance work and downtime, suitable for 24/7 continuous production.
6. Flexible Customization & Line Integration: Customizable belt width (300-1200mm), conveying length and angle (0°-25°); modular design supports horizontal/inclined conveying and seamless connection with XUANYU flour sieving machines, mixers and packaging equipment. Optional cleated belts/side guards prevent material spillage for inclined conveying of flour and granular materials.
7. Safe & Reliable Performance: Equipped with food-grade emergency stop buttons, overload protection and anti-slip devices; all electrical components meet IP65 protection grade, resistant to water and dust, ensuring safe operation in food processing workshops and avoiding equipment damage and material waste.

Working Principle

1. Hygienic Feeding: The milled or sieved flour is evenly fed onto the food-grade conveyor belt via a sealed hopper/feeder with guide plates, preventing dust leakage and material spillage at the feeding end.
2. Gentle Conveying: The motor drives the food-grade roller to rotate via a food-grade reducer, driving the anti-stick belt to run at a set speed. Flour moves synchronously with the belt along the enclosed path under the action of friction, with idler rollers supporting the belt to reduce resistance and ensure smooth conveying.
3. Dust-Free Discharging: Flour is smoothly transferred to the next process (mixing, packaging, storage) via the sealed discharging hopper at the end of the belt; the anti-stick belt surface and scraper device ensure complete material discharge with minimal residue.
4. Safety & Regulation: The tensioning device maintains stable belt tightness to prevent slipping; the overload protection system immediately cuts off power in case of abnormal operation (e.g., material blockage), and the emergency stop button ensures the safety of operators and equipment.

XUANYU Sieving Solution for Flour

Core Advantages

Flour-Specific Precision Sieving: Tailored exclusively for wheat flour, high-gluten flour, low-gluten flour, and whole-wheat flour sieving, integrating ultrasonic vibrating sieves and rotary vibration sieves. The optimized sieve structure and gentle vibration mode avoid flour agglomeration and overheating, with sieving accuracy ranging from 40μm to 500μm (40–325 mesh), ensuring uniform particle size distribution, pure flour quality, and consistent baking performance.

Food-Grade Hygiene & Safety: All contact parts (sieve mesh, sieve chamber, feeding hopper, discharging port) are made of AISI 304/316L stainless steel with polished, crevice-free surfaces, complying with FDA, 3-A, and BISSC food safety standards. The fully enclosed design prevents dust leakage, cross-contamination, and moisture absorption, ensuring the flour remains clean and meets food processing hygiene requirements.

Anti-Blocking & Anti-Agglomeration: Adopting ultrasonic anti-blocking technology and food-grade anti-stick coatings, it effectively solves the problem of fine flour particles blocking sieve meshes and agglomerating due to static electricity or moisture. The continuous online cleaning function ensures uninterrupted production, reducing the need for frequent manual cleaning and improving work efficiency.

Low Flour Loss & High Yield: Optimized internal flow channels and anti-residue design minimize flour adhesion on equipment surfaces, reducing raw material loss to ≤0.3%. The integrated sieving process avoids intermediate material transfer loss, and the sieve residue recovery system can reprocess coarse particles (such as bran) to further improve flour yield and reduce production costs.

Easy Operation & Low Maintenance: PLC+HMI touchscreen control enables one-key start-stop, adjustable vibration frequency and amplitude, and real-time monitoring of sieving status. Tool-free sieve mesh replacement (completed in 30 seconds) and detachable components facilitate quick cleaning and maintenance, reducing downtime and labor intensity.

Flexible Customization & System Integration: Modular design supports flexible combination of single-machine or multi-stage sieving equipment according to flour production scale (small workshops to large flour mills) and process requirements. Customizable sieve mesh specifications, flow rate (500 kg/h–20 t/h), and equipment size, perfectly matching flour milling, mixing, and packaging systems, adapting to different types of flour processing needs.

Working Principle

Flour Feeding: After milling, the crude flour is evenly fed into the vibrating sieve via a screw feeder or hopper, ensuring stable and uniform feeding without causing sieve mesh overload.

Precision Sieving: Driven by a high-frequency vibration exciter, the sieve body generates gentle linear or elliptical vibration. Under the combined action of vibration force and gravity, flour particles move forward and jump on the sieve surface; qualified fine flour particles pass through the sieve mesh, while coarse impurities (such as bran, broken wheat grains) and agglomerates are discharged separately.

Anti-Blocking & Cleaning: During the sieving process, the ultrasonic anti-blocking system works synchronously to break up agglomerated flour and clear blocked sieve meshes. The food-grade anti-stick coating prevents flour from adhering to the sieve chamber, ensuring smooth sieving and reducing residue.

Finished Product Collection: The sieved fine flour is collected through the lower discharge port and conveyed to the next process (mixing, packaging, or storage) via a conveyor. Coarse residues are discharged through the slag discharge port for reprocessing or other uses, completing the entire flour sieving process.
