基于温度—含氧量的全自动堆肥通风控制系统设计(Design of Temperature/Oxygen Concentration-based Aeration Control System for Aerobic Composting)
堆肥 通风 温度 含氧量
2009/8/11
采用工业计算机和下位机的监测控制方式,开发了基于温度-含氧量的全自动堆肥通风控制系统,并实现了软硬件的配套设计。运行试验表明:采用该工艺堆肥,时间一般为2周,高温期(55~65℃)可维持9d以上,能有效杀灭病原微生物,产品稳定性好;可在整个堆肥过程中实现自动在线监控堆体温度、含氧量和湿度,运行稳定。
低温气调贮藏下氧气含量对双孢蘑菇品质的影响(Effects of Oxygen Concentration on Storage Quality of Agaricus bisporus under Low Temperature and Controlled Atmosphere Storage)
双孢蘑菇 气调贮藏 氧含量 贮藏品质
2010/5/5
研究了在3℃低温和95%相对湿度的气调条件下,贮藏环境中O2含量对双孢蘑菇采后贮藏品质的影响。结果表明,体积分数为5%的低氧含量能够有效地抑制双孢蘑菇的呼吸强度,并延迟呼吸高峰的出现;随着贮藏环境中O2含量的降低,双孢蘑菇的失重减少、褐变程度降低、软化速度减缓;低氧含量能够使双孢蘑菇保持较高的可溶性固形物含量,延缓其成熟。 The effects of oxygen concentration o...
