Summary
Golden needle mushrooms are delicate fungi currently harvested by hand because traditional cutting machines damage them. Researchers designed a new high-speed rotating blade device that cuts mushroom roots cleanly and efficiently by using fast spinning cuts that minimize compression damage. The optimized machine reduces energy use by nearly 25% while improving cutting quality, making mushroom farming more practical and efficient.
Background
Golden needle mushroom (Flammulina velutipes) harvesting is currently performed manually due to challenges in mechanizing the process. The mushrooms grow in dense clusters with slender, fragile stems that are easily damaged by traditional low-speed cutting methods, limiting mechanization and automation in the industry.
Objective
This study aimed to design and optimize a novel high-speed rotary cutter device with a slitting cutting angle to improve harvesting efficiency, cutting quality, and reduce energy consumption in golden needle mushroom root cutting operations.
Results
Optimal cutter parameters were identified: sliding cutting angle 26°, edge angle 15°, thickness 2 mm. Best operational parameters: cutting speed 1400 r/min, turntable feed speed 6 r/min, cutting height 20 mm. The optimized design reduced cutting force by 39.4% and unit area power consumption by 24.5% while significantly improving cut surface flatness.
Conclusion
The high-speed rotary cutter device with optimized slitting angle design effectively addresses key challenges in mechanized golden needle mushroom harvesting by reducing damage, improving cutting quality, and reducing energy consumption. The device represents a practical solution for advancing mechanization in golden needle mushroom production.
