摘要
利用水蒸气蒸煮爆碎 (steam explosion)处理装置 ,研究了蒸煮温度和蒸煮时间对稻壳蒸爆过程的影响。得到多聚糖含量高的水相产物可用作提纯多聚糖的原料。经蒸爆后的稻壳表面致密层遭破坏 ,易于粉碎 ,且吸水性大大提高 ;蒸爆后的稻壳与其他材料配合可作为蘑菇的培养基。另外 ,通过对稻壳蒸爆前后成分分析发现 :水蒸气蒸煮爆碎过程可分解绝大部分的半纤维素 ,而其它成分基本不变。
A steam explosion apparatus was set up for the study of treatment of rice hull. Effects of cooking temperature and cooking time on liquid products, yield of exploded rice hull, content of different components in the rice hull were studied in detail. Liquid products, which contained 30%~40% oligomers, were a good feed for the purification of various oligomers. The exploded rice hull had a very good property in water absorption and was easy to be pulverized. It was proved that the exploded rice hull could be used partly as a culture medium for growing edible mushrooms. From the analyses of components in the rice hull, we could see that most of hemicellulose could be decomposed in the steam explosion process, while cellulose, lignin and SiO 2 was changed slightly.
