Temperature relationship in the freezer

we all know, freezers in different temperature, so have different purposes. If use the commercial freezer to store fruits and vegetables, then put on the temperature control is very strict. Because in the air-conditioner temperature determines the quality of fruits and vegetables and cold storage time. Below and take a look at the commercial freezer price, its relationship with fruits and vegetables. A refrigerated storage temperature is high, breathing, evaporate faster. Low temperature, breathing is abate, slow evaporation. Storage temperature fluctuation is large, also can promote the moisture to evaporate. High temperature, saturation deficit increases, accommodate the amount of water vapor in the air, to speed up the fruit and vegetable evaporation. Lower refrigerating temperature, can make the fruit and vegetable respiration, water evaporation is abate, to reduce the consumption of nutrients, microbial breeding, can make the storage period of fruits and vegetables. Fruits and vegetables refrigeration temperature in 0 ℃ or so commonly, but due to the different kinds of fruits and vegetables, variety, adaptability of low temperature are also different. For growth or mature fruit in summer in the south, is suitable for high temperature storage, improper or freezing in low temperature will affect the normal physiological function of the fruit, the quality and the flavor change or produce physiological disease, unfavorable to storage. Such as banana can't long-term in less than 12 ℃ temperature ripening, even short-term suffer from low temperature damage of banana and after ripening fruit still heart hard, black skin, these are the effect of temperature on fruits and vegetables in the commercial freezer. People later in order to make the cooler can better refrigerated fresh fruits and vegetables, to a large number of experiments. Experience has shown that storage temperature should be 6 - mandarin class 8 ℃, citrus is eight About 15 ℃, orange class is 5 ℃. The pineapple storage temperature should not be less than 6 ℃. And north in the fall and winter of ripe fruit, such as apple, pear, hawthorn, etc. , generally can endure low temperature, even in the case of slight freeze, don't hurt their living quality. This kind of fruit can be stored at 0 ℃ or so commonly, only is limited to prevent freezing. Learn from production practice, the appropriate crown, the red star apple at 0. 5 - 1 ℃ temperature storage, cockscomb, ralls appropriate in 0 - - - - - - 1 ℃ temperature storage, Chinese cabbage, green soy bean, onion, garlic in - 1 - Storage under 0 ℃, sword bean, green pea in 1 - 3 ℃ under storage. Therefore, fruits, vegetables, cooling storage should be controlled according to the different varieties of the most appropriate storage temperature, even the same species, also because of the variety, maturity, cultivation conditions are different. Therefore, when a large number of storage, prior to their optimum temperature choice experiment. Required storage temperature stability in the freezer, avoid violent change, these you can understand why it is important to the cooler temperature.
