ZOOMRY
1. Product Overview
The ZOOMRY grain spiral scraper conveyor is specialized equipment designed for global grain storage scenarios, focusing on efficient scraping and conveying of bulk grains such as wheat, corn, and rice, with a broad capacity range of 100–2,000 tph. Featuring three core designs — "anti-breakage spiral, grain depot-specific chassis, and full-process residue prevention" — it meets the specialized needs of grain handling for low breakage, ground protection, and high cleanliness.
Equipped with a 500–800 mm spiral system and an 800–1,600 mm wide Conveyor Belt, supporting 100-meter wireless remote control operation, it is perfectly suited for grain depot leveling and agricultural storage transfer scenarios. Certified by CE, EAC, and EU EC 1935/2004 food contact standards, the equipment stands out as the preferred choice for "high quality, strong adaptability, and easy maintenance" in grain scraper conveyors and grain depot handling equipment.
2. Specialized Grain Handling Advantages
The core competitiveness of the ZOOMRY Grain spiral scraper conveyor lies in its deep alignment with grain characteristics — prone to breakage, mold susceptibility, and high hygiene requirements — as well as the operational constraints of grain depots, such as limited space and ground protection needs.
Low-Breakage Design
The 6–8 mm thick wear-resistant manganese steel blades undergo rounded-edge polishing to eliminate sharp edges that could scratch grain particles. Inlaid alloy teeth adopt a 15° tilt angle arrangement, replacing traditional vertical grabbing methods to significantly reduce grain impact. Paired with a precisely adjustable spiral linear speed of 2.5–3.0 m/s — lowered to 2.5 m/s for fragile grains like rice and increased to 3.0 m/s for hard grains like corn — the grain breakage rate is controlled below 0.5%, far surpassing the industry average of 1.5%. For enhanced grain quality protection, the spiral scraper conveyor system uses layered scraping logic to avoid pile compression.
Grain Depot-Friendly Chassis Design
The 400 mm wide dual-configuration tracked chassis features rubber tracks (model 400×90×68, effective length 2.9 m) using food-grade high-elasticity rubber compliant with EU EC 1935/2004 standards, with ground pressure of only 0.07 MPa to protect depot floors. With a minimum turning radius of 5 m, it allows flexible movement in narrow gaps between grain piles. Optional steel tracks (model 400×135×54, effective length 3.6 m) are made of passivated Q355B steel with no sharp edges, offering high wear resistance for long-term operations. Both track types deliver 3,500 N·m torque for smooth start-stop under full load, with vibration amplitude maintained at ≤3 mm.
Full-Process Residue Prevention
The hopper's inner wall is lined with 1.5 mm thick PTFE anti-stick coating with a surface friction coefficient of only 0.04, achieving a grain residue rate of ≤0.2%. The "V-shaped" flow-guiding structure with 15° angled discharge port ensures residue-free grain transfer. The conveyor belt uses nylon-core polished anti-slip rubber with surface roughness Ra≤0.8 μm. Two sets of polyurethane cleaning scrapers at the head achieve a 99% cleaning rate, preventing cross-contamination between different grain types. For enclosed applications, Rain Covers protect grain from moisture and external contaminants.
3. Core Systems
Spiral Drive System
The drive core consists of 22–75 kW customized motors with IP55 protection and anti-corrosion-treated housing to withstand 60–80% high-humidity depot environments. Operating noise is ≤70 dB. The ZLY250 hard-tooth surface reducer achieves 97% transmission efficiency with stepless speed regulation of 0–30 r/min — set to 15 r/min for rice and 25 r/min for corn, balancing efficiency and low breakage.
Grain Depot-Specific Conveyor Belt System
Belt width ranges from 800–1,600 mm with nylon-core anti-slip rubber (longitudinal tensile strength 1,600 N/mm). The 15–30 kW electric drum has built-in overheat protection (automatic shutdown above 120°C). The 12–15 m long conveyor belt with 4-meter fixed discharge height directly connects to grain depot elevators or silo feed ports, eliminating secondary transfers. Side skirts made of food-grade rubber have an anti-aging lifespan exceeding 2,000 hours.
Precise Control and Food-Grade Hydraulic System
The 12-inch HMI touchscreen supports multiple languages and stores five sets of grain operation parameters for one-touch retrieval. The 100-meter wireless remote control allows operators to monitor from safe depot areas. The hydraulic system uses an 11–18.5 kW pump station with FDA-compliant food-grade hydraulic oil and stainless steel connectors, with an annual system failure rate below 0.5%.
4. Grain Depot-Friendly Transport and Installation
Modular Disassembly Design
The equipment disassembles into four standard units — spiral scraper, conveyor belt, tracked chassis, and control module — each sized for a 40-foot high-cube container, with single-unit weights ≤20 tons. This design reduces cross-border logistics costs by 40% compared to traditional integrated scraper equipment. Core components are factory-packaged with dust-proof and scratch-resistant materials.
High Pre-Assembly Ratio
The equipment is 90% pre-assembled at the factory, undergoing 80 hours of simulated grain depot full-load testing with mixed wheat and corn. On-site installation takes two people 2 hours for assembly plus ≤1 hour for hydraulic and electrical connections. Full commissioning by a skilled team completes in one day. ZOOMRY provides multi-language technical manuals and 24-hour online support.
5. Global Compliance and Grain-Specific Quality Testing
Global Compliance
The equipment has passed EU CE certification and EAC certification for CIS countries. Core grain-contact components comply with EU EC 1935/2004 and U.S. FDA 21 CFR Part 177 food contact material standards. The equipment also adheres to ISO 22000 food safety management systems with fully traceable production processes.
Grain-Specific Quality Testing
ZOOMRY's in-house grain equipment testing laboratory conducts rigorous testing: continuous 100-hour scraping of wheat, rice, and corn achieves breakage rates of 0.3%, 0.5%, and 0.2% respectively; residue tests result in ≤0.2 g/m², well below the 1 g/m² standard; hygiene tests show bacterial count ≤10 CFU/cm² with no E. coli or mold. Each unit undergoes 16 specialized tests including grain type switching, depot ground adaptability, and low-temperature startup before delivery.
