Conveying Machine

XUANYU Bucket Elevator is a high-efficiency, hygienic vertical material handling system engineered for food and grain processing, specially designed for seamless vertical lifting of flour, grain, sugar and other food-grade powders/granules. Adopting food-grade stainless steel construction and enclosed bucket design, it ensures dust-free, low-loss and gentle lifting, perfectly matching XUANYU flour sieving, conveying and packaging lines, complying with FDA/3-A/BISSC standards for all-scale food processing plants.

Core Advantages

1. Food-Grade Hygienic Construction: All material contact parts (buckets, casing, hopper) are made of AISI 304/316L stainless steel with polished, crevice-free and dead-corner-free surfaces, meeting FDA, 3-A and BISSC food safety standards. Easy to clean and sterilize, eliminating cross-contamination risks for flour processing.
2. Enclosed Dust-Free Lifting: Fully sealed casing and food-grade anti-spill buckets prevent flour dust leakage, moisture absorption and secondary pollution, maintaining a clean workshop environment and reducing raw material loss to ≤0.2%. No material scattering during vertical conveying.
3. Gentle Lifting & Flour Quality Protection: Optimized food-grade plastic/steel buckets with smooth inner walls and low-speed lifting mode avoid flour agglomeration, particle breakage and overheating, preserving the original particle size distribution and quality of flour for consistent baking performance.
4. High Lifting Efficiency & Stability: Heavy-duty chain/belt drive system with tension adjustment device ensures stable and continuous operation; customizable lifting height and capacity to match different production line requirements, enabling 24/7 continuous work with low failure rate.
5. Compact Structure & Space-Saving: Vertical design with small floor space, ideal for narrow workshop areas; easy to install and integrate with XUANYU stainless steel screw conveyors, food-grade belt conveyors and flour sieving equipment for a complete production line.
6. Easy Operation & Low Maintenance: PLC/HMI touchscreen control for one-key start-stop and speed adjustment; quick-release casing and detachable buckets for tool-free cleaning and maintenance; sealed bearings and wear-resistant components reduce daily upkeep and downtime, low noise (≤70dB).
7. Flexible Customization & Strong Adaptability: Customizable lifting height (1–30m), capacity (50kg/h–20t/h) and bucket type; optional food-grade plastic buckets (for light powder) or stainless steel buckets (for heavy granules); horizontal/vertical feeding/discharging to fit on-site layout.
8. Safe & Reliable Performance: Equipped with overload protection, emergency stop button, anti-breakage chain/belt and material level sensor; all electrical components meet IP65 protection grade, water and dust resistant, ensuring safe operation in food processing workshops and avoiding equipment damage.

Working Principle

1. Hygienic Feeding: The sieved or conveyed flour is evenly fed into the sealed feeding hopper of the elevator, with a guide plate to ensure smooth material entry into the moving buckets, preventing spillage and dust leakage.
2. Enclosed Vertical Lifting: The motor drives the chain/belt to rotate via a reducer, driving the evenly spaced buckets to move upward along the sealed stainless steel casing. Flour is held in the anti-spill buckets and lifted vertically without scattering or residue.
3. Stable Discharging: When the buckets reach the top of the casing, the flour is smoothly discharged into the sealed hopper via centrifugal force or gravity, and then transferred to the next process (mixing, packaging, storage) through connecting conveying equipment.
4. Safety Regulation: The overload protection system immediately cuts off power if the elevator is blocked by materials, preventing motor burnout; the tension adjustment device maintains stable operation of the chain/belt; emergency stop buttons at multiple positions ensure operator safety.
