Research on Corn Ears’ Storage by Rectangle Small-scale Farm Bin with Steel Framework in Jizhou

2021

The moisture of most newly harvested corn ears could be as high as 30% in Jizhou, and the method of air-drying on sides of roads, which is weather-sensitive, is mostly adopted in rural areas.Considering the small-scale farm bin has been used widely in the northeast of China, it is meaningful to explore its applicability and optimal thickness in Jizhou. In this study, JSWD-120 (4×1.5×2 m) is chosen and modified into tree small-scale bins with the thickness of 0.8 m, 1.0 m and 1.2 m. The newly harvest corn ears are stored from the middle October to early April and different quality index are analyzed timely. Results show that corn ears stored in the bin with the thickness of 1.2 m show good quality in terms of moisture of 14.05%±0.001%, lower fatty acid values of (51.59±0.007) mgKOH/100g, crude starch content of (68.66±0.171) g/100g and amylose content of 20.65%. Moreover, mycotoxins, such as deoxynivalenol and ochratoxin A, are not detected. Based on the experiment results, it is reasonable to consider wider utilization of JSWD farm bins to the south of China
