摘要

本研究在理论模型的基础上,以现有蒸煮挤出机的运行数据和实践为指导,设计了一种用于膨化零食生产的小容量单螺杆蒸煮挤出机。建筑使用当地可获得的工程材料,在满足卫生设计标准的中型机械车间进行,并使用木薯和脱脂大豆粉的混合物进行测试。所研制的挤出机的输送量、螺杆转速、料筒直径、长径比和功率要求分别为13.0 kg/h、200 rpm、40 mm、12和1.908 kW。2016年开发挤出机的成本估计为65万挪威克朗。所有处理的膨化率和胰蛋白酶抑制剂降低率分别为1.82 ~ 2.98和61.07% ~ 87.93%。本研究表明,低容量、经济实惠的实验单螺杆挤出机是可以在国内设计和制造的,可以扩大规模用于膨化零食的中试和工业应用。

Single-Screw Laboratory Extruder for Production of Expanded Products: Design, Construction and Performance Testing
In this study, a low-capacity single-screw cooking extruder for the manufacture of expanded snacks was designed based on theoretical models and guided operating data and practices of existing cooking extruders. Construction was carried out using locally available engineering materials in modest machine shops satisfying sanitary design criteria and tested using blends of cassava and defatted soybean flour. The extruder developed has throughput, screw speed, barrel diameter, length-to-diameter ratio and power requirement of 13.0 kg/h, 200 rpm, 40 mm, 12 and 1.908 kW, respectively. The cost of the extruder developed was estimated N650,000 in 2016. Extrudates had expansion ratio and trypsin inhibitor reduction which ranged from 1.82 to 2.98 and 61.07% to 87.93%, respectively, across all treatments. This study demonstrates that a low-capacity and affordable experimental single-screw extruder can be designed and built domestically which can be scaled-up for pilot and industrial applications for the production of expanded snacks.
