    氣調式冷庫

    氣調冷庫是在冷藏庫的基礎上增加氣體成分調節通過對貯藏環境中溫度、濕度、二氧化碳、氧氣濃度和乙烯濃度等條件的控制抑制果蔬呼吸作用和自我消耗使之處于近休眠狀態減少失水減少病害發生延緩其新陳代謝過程從而較長間的保持被儲物的質地、色澤口感、營養等基本不變更好地保持果蔬新鮮度達到延長果蔬貯藏期的目的是目前國際上使用最普遍效最好、最先進的貯藏保鮮技術之一
    The air-conditioning cold storage is based on the increase of gas composition in the cold storage. By controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, the respiration and self-consumption of fruits and vegetables are reduced to reduce the water loss. Reducing the occurrence of diseases and delaying its metabolic process, so as to maintain the texture, color, taste and nutrition of the storage materials for a long period of time, to maintain the freshness of fruits and vegetables, and to extend the storage period of fruits and vegetables, the most common use in the world is currently the best. One of the most advanced storage and preservation technologies
     
     

    氣調庫儲藏的原理

    傳統的果蔬貯藏保鮮方法有簡易貯藏、通風庫貯藏輻射保鮮化學保解冷庫保鮮簡易貯藏通風庫貯藏設備簡單投資少但貯藏效果差貯藏期短腐爛損失嚴重輻射及化學保鮮在部分水果上有一定適用性但存在輻射及化學殘留污染不是所有果疏都能應用氣調貯藏能在適當低溫條件下通過改變貯藏環境氣體成分相對溫度最大程度地創造果蔬貯藏最佳環境其效果表現在以下方面氣調貯藏營造的低氧(一般02含量為1%5%適當的CO2濃度能有效地抑制呼吸作用減果蔬中營養物質的損耗同時抑制病原菌的滋生繁殖控制某些生理病害的發生清除貯藏環境氣體中的乙烯以抑制其對果蔬的催熟作用延緩后熟和衰過程增加環境氣體中的相對濕度以降低果蔬的蒸騰作用從而達到果蔬長期貯藏保鮮的目的
    The traditional method of storage and preservation of fruits and vegetables has simple storage, ventilation storage, radiation preservation, chemical preservation, cold storage, fresh storage, simple storage, ventilation storage, simple storage, low storage, but poor storage. Short storage time, short decay, severe radiation and chemical preservation. Sexual but there are radiation and chemical residual pollution. Not all the fruits can be used. The modified atmosphere can be used to create the optimal environment for the storage of fruits and vegetables by changing the relative temperature of the gas components under the appropriate low temperature conditions. The effect is as follows: Hypoxia (usually 02 content of 1% 5%) The appropriate CO2 concentration can effectively inhibit the respiration and reduce the loss of nutrients in fruits and vegetables while inhibiting the growth and reproduction of pathogenic bacteria to control the occurrence of certain physiological diseases. In order to inhibit the ripening effect of fruits and vegetables, the relative humidity in the ambient gas is increased to reduce the transpiration of fruits and vegetables, thereby achieving the purpose of long-term storage and preservation of fruits and vegetables.
     

    氣調庫儲藏的原理

    構成氣調庫一般由氣密庫體氣調系統制冷系統加濕系統壓力平衡系統以及溫度濕度、02.Co2氣體自動檢測控制系統構成 
    The air conditioning library is generally composed of a pressure balance system of the air conditioning system air conditioning system refrigeration system humidification system and temperature and humidity, 02.Co2 gas automatic detection and control system
     

    氣調貯藏效果

    抑制呼吸作用減少有機物質的消耗保持果蔬優良風味和芳香氣味
    抑制水分蒸發保持果蔬新鮮度
    抑制病原菌的滋生繁殖控制某些生理病害的發生降低果實腐爛率
    抑制某些后熟酶的活性抑制乙烯產生延緩后熟和衰老過程長期保持果實硬度有較長的儲藏期
    Inhibition of respiration reduces the consumption of organic matter and maintains the excellent flavor and aroma of fruits and vegetables
    Inhibit water evaporation to maintain freshness of fruits and vegetables
    Inhibit the breeding of pathogenic bacteria, control the occurrence of certain physiological diseases, reduce the rate of fruit decay
    Inhibition of certain post-mature enzyme activities inhibits ethylene production delays Post-ripening and senescence processes maintain long-term fruit firmness for a long shelf life
     

    控制系統

    要使氣調庫達到所要求的氣體成分并保持相對穩定除了要有符合要求的氣密性庫體外還要有相應氣體調節設備、管道、閥門所組成的系統即氣調系統整個氣調系統包括制氮系統、二氧化碳脫除系統乙烯脫除系統溫度、濕度及氣體成分自動檢測
    To make the air-conditioned storage reach theand maintain the relative stable, it is required to equip es apart from the airtight storage that meets with em,carbon dioxide deprivation system,ethylene defection and control system.
     
     

    采用桶泵機組特點

    采用桶泵機組后回氣在桶中實現氣液分離后使進入壓縮機的工質實現為干燥氣體避免了壓縮機濕沖程運行的可能性
    采用氟泵強制供液方式多倍量滿液供液由于蒸發器內供液量工治流速加快使蒸發器的冷卻效率提高從而提高了通型設備的換熱效果桶泵內氣液間的相互換熱(氣過熱液過冷)取得了雙底的效果從而有效解決了壓縮機氟系統的回油問題
    桶泵機組裝有自動手動回油裝置系統中換熱器的油高校的而回到壓縮機有效解決了壓縮機氟系統的回油問題提高系統運行的可靠性
    After the barrel pump unit is used, the gas return to the gas in the barrel is realized, and the working medium entering the compressor is realized as a dry gas to avoid the possibility of the compressor running on the wet stroke.
    The use of a fluorine pump to force the liquid supply method to multiply the full liquid supply due to the increase in the flow rate of the liquid supply in the evaporator, so that the cooling efficiency of the evaporator is improved, thereby improving the heat exchange effect of the through-type equipment. The heat exchange (gas superheated liquid is too cold) has achieved the effect of double bottom, which effectively solves the oil return problem of the compressor fluorine system.
    The barrel pump unit is equipped with an automatic manual oil return system in the heat exchanger of the oil university and returns to the compressor to effectively solve the oil return problem of the compressor fluorine system and improve the reliability of the system operation.
