果蔬保鮮冷庫的濕度調(diào)節(jié)辦法

果蔬存放于果蔬保鮮冷庫中可以延長果蔬的儲藏期限,不過如果保鮮冷庫管理不當(dāng),也不能起到很好的保鮮儲藏果蔬的作用,那保鮮冷庫的投入使用就變得沒有意義了。對于果蔬來說,果蔬中含有的大量水分是維持果實(shí)生命活動和新鮮品質(zhì)的必要條件。采摘后的果蔬,不能再從母體上獲得水分的供給,在長期儲藏過程中,逐漸蒸發(fā)水分。大多數(shù)水果蔬菜其干耗(重量損失)超過5%時(shí),就會出現(xiàn)枯萎等鮮度下降的明顯象征。特別是水果,當(dāng)于耗達(dá)5%以后就不可能恢復(fù)原狀。所以在果蔬保鮮冷庫中儲藏果蔬除了要留意制冷系統(tǒng)的運(yùn)行是否能持續(xù)保持果蔬保鮮冷庫的低溫環(huán)境,還要留意保鮮冷庫中的濕度是否合適。
The fruits and vegetables stored in fresh fruits and vegetables in cold storage could prolong the storage period of fruits and vegetables, but if the improper management of refrigeration storage, can not play well the role of fruits and vegetables, the refrigeration is put into use becomes meaningless. For fruits and vegetables, a large amount of water contained in fruits and vegetables is a necessary condition for maintaining the life activities and fresh quality of fruits. After picking fruits and vegetables, can not be obtained from the mother of the supply of water, in the long-term storage process, the gradual evaporation of water. Most fruits and vegetables, dry loss (weight loss) of more than 5%, there will be a marked decline in the degree of Wilt and other fresh symbol. Especially fruit, when the consumption of up to 5%, it is impossible to restore the status quo. So in fruits and vegetables preservation of fruits and vegetables in addition to storage of fruits and vegetables in addition to pay attention to the operation of the refrigeration system is able to maintain the fruits and vegetables fresh cold storage of low temperature environment, but also pay attention to fresh cold storage in the humidity is suitable.
果蔬的水分蒸發(fā),一方面是由于呼吸作用,散發(fā)出一部分水分;另一方面是儲藏環(huán)境的空氣濕度過低,引起果蔬枯萎,降低了商品價(jià)值。因此,高溫庫的濕度要很好地進(jìn)行調(diào)節(jié),果蔬保鮮冷庫的濕度一般要求在85~90%,根據(jù)果蔬種類不同略有浮動。如果濕度過低,可在鼓風(fēng)機(jī)前配合自動噴霧器,隨冷風(fēng)將細(xì)微小霧送入庫房空氣中,加濕空氣。沒有自動噴霧器,也可在地面上灑些清潔的水,或?qū)竦牟菹w在包裝容器上,來增加冷藏間的相對濕度。但如果濕度過高,果蔬的表面過于潮濕,有時(shí)還凝有水珠,給微生物滋生創(chuàng)造了條件,果蔬容易腐爛,這時(shí)可在庫內(nèi)放些干石灰、無水綠化鈣或干燥的木炭吸潮。高溫冷藏間的溫度和相對濕度都應(yīng)盡量保持穩(wěn)定,不得有較大幅度波動,否則會刺激果蔬的呼吸作用,增加消耗,另外果蔬還會“出汗”,降低了它的儲藏性。
The water evaporation of fruits and vegetables, on the one hand, is due to respiration, emitting a part of moisture; on the other hand, the storage environment of the air humidity is too low, causing fruit and vegetables wilt, reduce the value of goods. Therefore, the high temperature storage of the humidity to be very good to adjust the humidity of fruits and vegetables fresh cold storage in 85~90%, according to the different types of fruits and vegetables slightly floating. If the humidity is too low, can be in front of the blower with automatic sprayer, with the cold air will be fine small mist to send storage room in the room, humidification air. No automatic sprayer can also sprinkle clean water on the ground, or the wet straw cover on the container, to increase the relative humidity of storage room. But if the humidity is too high, and the surface is too wet, sometimes there is water to condensate, microbial breeding to create the conditions for fruits and vegetables are perishable, then in a library, put some dry lime green or dry anhydrous calcium absorbent charcoal. High temperature storage room temperature and relative humidity should be kept stable, no fluctuations, otherwise it will stimulate the respiration of fruits and vegetables, increase the consumption of fruits and vegetables, also will be sweating, it reduces the storage.
