Abstract: 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.
