气调库的使用的具体的特点介绍

作者:admin 来源:本站 发布时间:2018-3-13 20:06:23

气调库库体建设不仅要求隔热保温、防潮,而且要求能阻隔气体,要求较高的气密性,以维持库内所需的氧气和二氧化碳气浓度,并在库内气压变动时,库体能承受一定的压力。气密层通常采用镀锌铁板、薄铁板焊接密封,也有采用高密度胶合板,铝箔夹心板来粘合密封。
The construction of gas storage reservoir not only requires thermal insulation and moisture-proof, but also requires blocking gas and requiring higher air tightness to maintain the concentration of oxygen and carbon dioxide in the reservoir. When the barometric pressure changes, the storeroom can bear certain pressure. The airtight layer usually adopts galvanized iron plate, thin iron plate welding seal, and also has high density plywood, aluminum foil sandwich plate to glue and seal.
气调库内的气体成分要靠气调设备来调节,主要是降氧和二氧化碳脱除设备。降氧设备从初级到高级的四种类型是,燃烧式制氮机、碳分子筛制氮机、中空纤维膜制氮机和裂解氨制氮机。二氧化碳脱除设备主要用活性炭吸附洗脱,也可用氢氧化钢水溶液洗脱,还可用硅橡胶膜过滤来洗脱,最简单是用消石灰吸收。

The gas composition in the gas reservoir should be regulated by the air conditioning equipment, which is mainly the equipment for reducing oxygen and removing carbon dioxide. The four types of oxygen reduction equipment from primary to advanced are combustion nitrogen making machine, carbon molecular sieve nitrogen making machine, hollow fiber membrane nitrogen making machine, and pyrolysis ammonia nitrogen making machine. Carbon dioxide removal equipment is mainly activated carbon adsorption and elution. It can also be eluted by hydrated steel solution, and can also be removed by silicone rubber membrane filtration. The simplest way is to use lime to absorb.

气调库能根据不同果蔬的要求调控适宜的温湿度以及低氧和高二氧化碳气体环境,并能排除其呼吸代谢放出的乙烯等有害气体,从而达到比单纯冷藏更好的抑制产品呼吸强度,延迟后熟衰老的贮藏保鲜目的。
CA storage of fruits and vegetables according to the different requirements of the regulation of suitable temperature and humidity and low oxygen and high carbon dioxide environment, which can eliminate the respiratory metabolism of ethylene release and other harmful gases, so as to inhibit the respiratory intensity of simple cold storage products than better, delayed ripening and senescence of storage preservation purposes.
气调库虽然具有上述优点,但并不是什么果蔬都可放到气调库内贮藏,而且贮藏效果都会超过冷藏的。气调库是一种大规模集中进出库贮藏、销售的保鲜设施,它不像普通冷库那样进出灵活,因为整个库间调节一次气体成分较费事。集中短时间收贮装满一库间产品之后,须将库门密封好,然后靠制冷和气调机械来调节内部的温度和气体。贮藏期间管理人员不能随意进库(若进入需配戴呼吸器),一般只能通过观察孔去查看内部情况和根据市场需要,一直到贮藏结束才能开库,使其气体恢复正常,才能进入出货。
Although the gas storehouse has the above advantages, but not what fruits and vegetables can be stored in a gas reservoir, and the storage effect will be more than refrigerated. The air conditioned warehouse is a large-scale preservation and storage facility for storing and selling in large scale. It is not as flexible and flexible as the ordinary cold store, because adjusting the gas composition between the entire storages is more difficult. After a short time centralized storage a library full of products, should be sealed by the door, and then refrigeration machines to regulate the internal temperature and gas. During storage, management personnel can't enter the library at will. If we need to wear respirator when entering, we can only observe the internal condition and observe the market demand through the observation hole, until the end of storage, so that we can open the storehouse and make the gas return to normal, so that we can enter the shipment.
气调库贮藏(简称“CA贮藏”),主要适宜贮藏采后具有典型呼吸跃变(高峰)的苹果(如金冠、红星等元帅系苹果)、梨(洋梨、香梨、鸭梨等人猕猴桃等果品。国际国内能用气调库贮藏的果品种类不多,柑橘、香蕉、葡萄等不适合气调库贮藏。至于蔬菜的气调库贮藏,国际国内很少应用。
The storage of modified atmosphere storehouse (short for "CA storage") is mainly suitable for storing apples that have typical climacteric climacteric (such as golden delicious, red star and other Apple), pear (pear, pear, pear and kiwi fruit). There are not many kinds of fruits stored in international and domestic gas storehouses. Citrus, bananas, and grapes are not suitable for storage in gas storage. As for the storage of vegetable gas storehouse, it is rarely used in international and domestic.
就是适宜气调库贮藏的苹果、梨等,由于入贮要求较高,操作管理复杂费事,加之市场效益不高等原因,我国这些年各地建的一大批气调库,真正用气调库贮藏创效益的不多,多数都改做普通冷库用。所以,不能认为气调库是什么都能贮的高效贮库。切莫轻易耗费大笔资金,盲目立项建设气调库。但若搞苹果出口贸易,必须建气调库贮藏。
Is suitable for gas storage of apple, pear and so on, because of higher requirement to the operation and management of complex, cumbersome, and the market efficiency is not high in our country these years, built around a large number of CA storage, real gas storage efficiency is not much, most of them to do the ordinary cold pool. Therefore, it is not considered that the gas reservoir is the efficient storage of what can be stored. Not easy to spend a lot of money, blindly set up the construction of gas reservoir. But if we make apple export trade, it must be stored in gas storage.
