When evaluating machinery, prioritize production capacity (e.g., 10,000 to 30,000 sticks per hour) to match your business scale. Key components include the rotary cutting machine, tri-section carver, and polishing machine. Ensure the equipment uses food-grade stainless steel (SUS304) for parts in contact with wood to prevent contamination. Additionally, check the thickness tolerance; high-quality machines should maintain a precision of ±0.05mm to ensure compatibility with automated ice cream filling lines.
