In the soybean processing industry chain, by-products such as soybean hulls and soybean meal, characterized by poor self-flowing and a propensity to bridging, have long plagued enterprises' storage and discharging efficiency. Hongrain has developed the soybean meal discharging machine to target this industry's pain point. Innovative structural design and intelligent control provide an efficient and reliable solution for forced reclaiming of materials like soybean hulls and soybean meal.
1. Discharging Challenges: Deep-seated Difficulties from Material Properties and Process Bottlenecks
- Constraints from Material Properties
Soybean meal and other powdery materials have fine particles and high fiber content, making them prone to moisture absorption and caking in humid environments. Their poor self-flowing results in a large natural angle of repose, rendering traditional gravity discharging inadequate for large-scale production needs. In particular, arch structures tend to form at the bottom of conical silos, blocking the discharge outlet.
- Bottlenecks in Process Efficiency and Safety
Unsmooth discharging prolongs operation cycles and requires frequent manual intervention, such as loosening arches and clearing blockages, which not only increases operational costs but also poses safety risks such as dust explosions and mechanical injuries.
2. Hongrain's Solution: Core Technological Breakthroughs of the Spiral Cantilever Discharging Machine
- Synergistic Effect of Forced Discharging and Anti-Bridging
The equipment uses a spiral shaft that rotates to convey materials while revolving around the silo center, creating dual forces to achieve uniform full-silo discharging. This design follows the FIFO (First-In-First-Out) principle, effectively inhibiting material caking caused by stagnation. The powerful main shaft and revolution drive ensure the machine's forced start capability.
- Intelligent Control System
The electrical system communicates with the customer's central PLC via Ethernet, supporting functions such as remote and local operation, one-button start, alarm, and shutdown under abnormal conditions, and operation status recording, featuring high automation.
- Safety and Maintenance Convenience
External Power Design: Power output components are placed outside the silo and do not rotate, ensuring a safe and convenient power supply, eliminating dust explosion risks, and enabling high maintainability.
- Technical Parameters
Applicable silo diameter: 8-16m (for materials with poor self-flowing and a high tendency to form intricate lumps/arches, e.g., soybean meal, rapeseed meal, wheat bran, etc.
8-21m (for materials with poor self-flowing but low tendency to form intricate lumps/arches, e.g., soybean hulls, rice bran meal, etc.
Liquidation capacity: 10- 150tph
Hongrain's discharging machine, centered on "structural innovation + intelligent control," resolves the self-flowing bottlenecks and safety risks in the by-product discharging process. It has mature application cases in the oil processing industry, including Kerry Oils and Grains, Jiusan Tianjin, and Gangqing Oils, demonstrating stable and reliable performance. It provides a standardized path for enterprises to achieve cost reduction, efficiency improvement, and green production. In the future, as the feed and food industries raise requirements for raw material quality, this technology will continue to empower the intelligent transformation of the industrial chain.
