蘋果大多數品種最適宜的貯藏溫度是-1~0℃,少數品種如青香蕉、小國光、印度等能耐-2℃的低溫。
The most suitable for apple varieties of storage temperature is -1~0 DEG C, low temperature and few varieties such as green banana, small Kuang, India. -2 c.
蘋果冷庫除作好庫體降溫備用外,還須注意以下事項:
Apple cold storage in addition to the library cool standby, but also pay attention to the following matters:
①果實在入蘋果冷藏庫前應及時進行預冷,盡早降低果溫,減少果實釋放的呼吸熱,除去果實帶回的田間熱。
Before entering the apple cold storage, the fruit should be pre cooled in time, reduce the temperature of the fruit as early as possible, reduce the heat of respiration and remove the heat from the fruit.
預冷常用水冷、冰冷、冷風等幾種冷卻方法。
Cold, cold, cold wind and other cooling methods.
目前我國主要采用冷風冷卻,強制性地進行庫內空氣循環、使冷熱空氣不斷交換對流而達到果實迅速降溫目的。
At present, our country mainly uses the cold wind cooling, the compulsory air circulation in the library, so that the hot and cold air exchange convection and achieve the purpose of rapid cooling fruit.
②果實入蘋果保鮮庫要分品種和等級堆垛。
The fruit into the apple storage to be divided into different varieties and grades of stacking.
堆垛時一定要離開庫壁30厘米以上,離開庫頂50厘米以上(不能高于出風口),離開蒸發器2米以上。
Stacking must leave the library wall 30 cm above, leaving the top 50 cm above the library (not higher than the air outlet), leaving the evaporator 2 meters above.
③在貯藏過程中,應保持庫溫的穩定,嚴格按要求掌握庫溫度,溫度變化幅度應控制在±1℃以內。 為防止果實水分蒸發,蘋果冷庫內相對濕度應保持90%左右。
In the process of storage, the temperature should be kept stable, master library in strict accordance with the requirements of temperature, temperature changes should be controlled within 1 DEG C. In order to prevent the evaporation of the fruit, the relative humidity in the apple cold storage should be kept about 90%.
貯藏后期要及時進行果實品質變化的檢測,要分期分批取樣并置于常溫下,觀察果實的貨價期,確定果實是否還有繼續貯藏的價值。
Storage period to timely detection of fruit quality changes, to stage sampling and under normal temperature, observe the fruit shelf-life, determine whether there is continued storage value of fruit.
