The use of a laser machine for the perforation process in bread for creating ventilation holes has the following advantages: High Precision: Laser machines can achieve extremely high precision, enabling accurate perforation on the surface of the bread to ensure precise hole shapes and positions. Non-Contact Processing: Laser perforation is a non-contact method, avoiding physical deformation or damage to the bread's surface and maintaining its integrity. Flexibility: Laser machines are highly flexible and can be customized based on different design requirements and bread types, accommodating various hole sizes and arrangements. High Efficiency: Laser perforation operates at a fast speed, making it suitable for large-scale production and improving overall production efficiency. Clean and Environmentally Friendly: Laser perforation is a pollution-free process, requiring no additional cooling fluids or lubricants, aligning with food safety and environmental requirements. Fine Control: Precise control over the diameter, depth, and spacing of each hole can be achieved, ensuring consistent perforation results. Automation Integration: Laser machines can be integrated into automated systems, enabling automated production lines and reducing manual intervention.
