摘要

Tool miscuts during single-process coring often cause flower bud damage. This study proposed a double-process coring method to address this issue. Experiments were conducted to minimize the cutting damage rate of broccoli (CDR-B). These included both single-factor and multi-factor experiments. Single-factor results indicated that the CDR-B exhibits a significant cubic polynomial relationship with the inner diameter of the cylindrical cutting tool (ID-CCT) and the cutting position of the arc-shaped cutting tool (CP-ACT), and a quadratic relationship with the cutting depth (CD-CCT). Multi-factor orthogonal experiments revealed that the CP-ACT had the most significant impact on CDR-B, followed by CD-CCT and ID-CCT. The optimal parameter combination was determined to be an ID-CCT of 55 mm, CD-CCT of 80 mm, and CP-ACT of 45 mm, yielding a predicted CDR-B of 1.36%. Validation experiments confirmed a CDR-B of 1.39%, representing a 15.76% improvement over the experimental table’s best result. This study provides a theoretical basis for designing low-damage broccoli coring equipment.
