ANALYSIS OF OPTIMAL PARAMETER IN DRY SHRIMP PEELING PROCESS
Keywords:
Dried Shrimp, Experimental Design, Dry Shrimp Peeling ProcessAbstract
This research aims to analyze the factors influencing the peeling efficiency of dried shrimp shells and determines the optimal parameters for the shell separation process using a dried shrimp peeling machine. A 3-level factorial experimental design was applied to identify root causes and screen factors potentially affecting the outcomes. Based on brainstorming, three factors were selected for investigation, each with three levels: impeller speed at 115–120, 145–150, and 175–180 RPM; moisture content at <19%, 19–21%, and >21%; and three impeller shapes, namely cylindrical, rectangular, and hybrid designs. The research findings show that the highest peeling efficiency of dried shrimp, at y = 292.33 PCS, can be achieved with the following optimal parameters: motor speed (Sp) of 145–150 RPM, moisture content (Mo) of 19–21%, and impeller shape (Sh) type 3 (hybrid design). The 95% confidence interval (CI) indicates that the mean peeling efficiency is likely to fall within the range of 280.83 to 303.84, with a 95% probability.
