摘要
为开发节能高效的柑桔贮藏保鲜库,通过设计、性能测试、贮藏试验,研制出湿冷通风库。库体总热阻为5.07m2·℃/W,耗能为2.27kW·h/100m3·h,比普通冷库减少能耗50%;温度可降至-5℃以下,自动控制精度±0.1℃;相对湿度可升到99%,自动控制精度±2%。锦橙、椪柑在湿冷通风库中贮藏的呼吸强度分别为4.29、2.34mg/kg·h,锦橙湿冷通风贮藏150d腐烂率为6.32%,椪柑湿冷通风贮藏120d腐烂率为5.38%,腐烂率明显低于在改良通风库贮藏(锦橙10.67%、椪柑12.04%)。锦橙湿冷通风库贮藏150d,有机酸质量浓度0.58g/100mL、总糖质量浓度8.33g/100mL、维生素C质量浓度41.11mg/100mL,椪柑湿冷通风库贮藏120d,有机酸质量浓度0.22g/100mL、总糖质量浓度6.41g/100mL、维生素C质量浓度15.62mg/100mL,品质和风味也优于通风库贮藏。结果表明,湿冷通风贮藏是具自然冷源降温、机械制冷、加湿功能节能的贮藏设施,柑桔贮藏效果良好。
In order to study energy-saving and efficient techniques for citrus storage,the author developed a new type of storehouse— the ventilating storehouse with refrigerating and wetting systems. The system performance test and storage test were conducted. The thermal resistance of the storehouse was 5.07 m2·℃ /W,and the energy consumption was 2.27 kW·h/100 m2·h which was 50% of the energy consumption in cold storage. In the storehouse,temperature could fall to-5℃ below,control accuracy was ±0.1℃,humidity could rise to 99% and control accuracy was ±2%. In the ventilating storehouse with refrigerating and wetting systems,the respiration rate of citrus was 4.29 mg/kg·h（for Jinchen） and 2.34 mg/kg·h（for Ponkan） respectively,which was lower than that in the simple ventilating storehouse,and the decay rate of citrus was less,which was 6.32%（for Jinchen store 150 days） and 5.38%（for Ponkan store 120 days） respectively,and the quality and the flavor were better. After 150 days storage for Jinchen,organic acid was 0.58 g/100 mL,sugar was 8.33 g/100 mL,vitamin C was 41.11 mg/100 mL,after 120 days storage for Ponkan,organic acid was 0.22 g/100 mL,sugar was 6.41 g/100 mL,vitamin C was 15.62 mg/100 mL. The results show that the ventilating storehouse with refrigerating and wetting systems are an energy-saving and good effect storage facility,in which the temperature decrease with nature cold source or refrigerating system,and humidity increase in the storage.
