Abstract

This study aims to analyze the comparison between straight blade and wavy blade designs on the slicing quality of crackers using a cracker-cutting machine. The parameters observed included cutting time, production capacity, cutting frequency, slice thickness, and uniformity of the resulting slices. The tests were conducted using 1 kg of crackers for each test, with motor speed variations of 1,000 rpm, 1,200 rpm, and 1,400 rpm, and slice thicknesses of 2 mm and 3 mm. The test results showed that the wavy blade had a higher production capacity than the straight blade at the tested rotational speeds. The highest production capacity of the wavy blade was obtained at 1,000 rpm, reaching 64.29 kg/hour, while the straight blade achieved 51.43 kg/hour. At 1,200 rpm, the production capacity of the wavy blade was 61.02 kg/hour, while at 1,400 rpm it was 63.16 kg/hour. Meanwhile, the straight blade produced capacities of 50.00 kg/hour and 50.70 kg/hour, respectively. In terms of quality, the straight blade tended to produce more regular and stable slices, while the wavy blade increased cutting capacity but required greater attention to slice uniformity. The cutting frequency of both blade designs at 1,400 rpm using two blades was 2,800 cuts/minute, with a blade peripheral speed of 18.31 m/s. Based on these results, the wavy blade design was superior in terms of production capacity, while the straight blade was better in terms of slice regularity and uniformity. Keywords: Cracker-Cutting Machine, Straight Blade, Wavy Blade.
