摘　　要：【目的】研究设计并制造一款新型加工番茄果实全自动耐压力测定仪。【方法】以不同品种的新鲜加工番茄果实为试材,分析对测定仪的制造工艺及开展耐压试验的重要性,并比较不同仪器用以验证该仪器的性能。【结果】石番45、亨氏3501与其它4种加工番茄相比品质较高,耐压性较好(13.58 mm/个);单果测定耐压力会受到果实果型指数、单果重、果肉厚度等的影响;全自动耐压测定仪可以准确记录耐压力值及变形值的变化过程,且果实破裂瞬间呈现明显变化,数据清晰且精密度高;测定1次即可得到某品种果实平均耐压力;测试范围宽(0~5000 N),测试行程远(0~140 mm),运行速度可调节(0~200 mm/min无级变速)。【结论】耐压力测定仪不受环境影响,数据精密度高;可有效用于测定不同品种加工番茄耐压力大小,测定效率高;操作简单、经济实用。【Objective】This research aims to design and manufacture a new type of automatic stress tolerance tester for tomato fruits.【Methods】Different varieties of fresh tomato fruits were used as test materials to carry out pressure test.The manufacturing process of the measuring instrument and the importance of pressure test were analyzed,and different instruments were compared to verify the reliability of the instrument.【Results】Shifan 45 and Heinz 3501 had higher quality compared with the other 4 kinds of tomatoes;the pressure tolerance of single fruit will be affected by the fruit type index,single fruit weight,pulp thickness,etc.;the fully automatic pressure tester could accurately record single fruit and the change process of the average pressure resistance value and deformation value,and the fruit showed obvious changes at the moment of rupture,the data was clear and accurate;the average value of the pressure resistance of a variety of fruits could be obtained after one measurement;the hardness and flexibility can be measured;the test range was wide(0-5,000 N)with long test stroke(0-140 mm),and the operating speed was adjustable(0-200 mm/min stepless speed change).【Conclusion】The pressure resistance tester manufactured in this study is not affected by the environment,and the data is more accurate,so it can be effectively used to measure the pressure resistance of different varieties of tomatoes and improve the measurement efficiency;What is more,it is simple to operate,economical and practical,and has a wide range of popularization values.
