Abstract

A 2 in 1 chopper and flour machine is a machine device designed to perform two main functions at once, namely chopping and flouring certain ingredients. This study aimed to assess the performance of the 2 in 1 type YCC985S chopper and flour machine in corn flour production, employing varied sieve sizes. The research, conducted at the Sub-Laboratory of Agricultural Energy and Sub-Laboratory of Machinery, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, spanned from November 13 to December 19, 2023. The descriptive method was employed with treatments involving different sieve sizes utilizing a pulley size A-21 cm. Observation data used in this study are : 1) Input (kg) and Output (kg), 2) Flouring time, and 3) electric power (W). While the observation parameters used in this study are : 1) Energy Requirements (Wh), 2) Percentage of Material remaining in the Tool, and 3) Effective Working Capacity (kg/jam). The data and parameters apply to 2.5 mm and 3.5 mm sieves. Material weights of 1 kg, 2 kg, and 3 kg were applied in each treatment, and three repetitions were conducted on sieves measuring 2.5 mm and 3.5 mm in diameter. The outcomes revealed that the flour yield on 2.5 mm and 3.5 mm sieves was 1.85 kg and 1.81 kg, respectively, influenced by the material and sieve dimensions. Material and sieve variations also impacted electric current, voltage, power, milling time, and energy requirements. The study demonstrated that the 2.5 mm sieve exhibited an average electric current of 6.47 A, compared to 6.57 A for the 3.5 mm sieve. Additionally, the average voltage, power, and energy requirements were lower for the 2.5 mm sieve, resulting in longer milling times compared to the 3.5 mm sieve. Notably, the highest material residue percentage was observed with the 3.5 mm sieve at 1 kg weight (16.50%), while the lowest residue occurred with the 2.5 mm sieve at 3 kg weight (5.83%). The maximum working capacity was achieved with the 3.5 mm sieve at 3 kg weight (25.59 kg/h), contrasting with the minimum working capacity of the 2.5 mm sieve at 1 kg weight (15.31 kg/h). Finally, the highest difference in engine rotation speed was recorded with the 3.5 mm sieve at 3 kg weight (53.67 RPM), while the lowest speed decrease occurred with the 2.5 mm sieve at 1 kg weight (20 RPM). The difference in engine rotation speed on a 2.5 mm sieve is 30.67 RPM and the difference in engine rotation speed on a 3.5 mm sieve is 40.11 RPM.
