Abstract

The refrigerator is a rectangular container, one side of which is comported a small part of inner space for placing an air-conditioned unit and a refrigerating unit. The air-conditioned unit produces an inert gas and is connected to the storage chamber by ducts and valves. The refrigerating unit is connected with a fan in the storage chamber. An ethylene or carbon dioxide removing unit can be connected to the storage chamber by ducts and valves, if necessary. A humidifier is provided in the chamber. The two parts of the container are airproof each other. The storage chamber is closed by an airproof door. The other end of the container is closed by a venting shutter. Advantage of the above is that inert gas can restrain breath of fruit, minimize its metabolism, furthest delay its after maturation. Therefore, fruits may be preserved for a long period, especially longer than general low-temperature storage. The refrigerator can be used for road, rail transportation and large refrigerated storage.

Description

气调保鲜冷藏銪 技术领域  TECHNICAL FIELD
本实用新型涉及一种储藏保鲜水果、 蔬菜的设备。 背景技术  The utility model relates to a device for storing fresh-keeping fruits and vegetables. Background technique
水果、 蔬菜的储藏保鲜， 有很多方法， 比如低温保鲜， 真空保鲜， 化学保鲜等， 低温保鲜是原始的储藏方法， 也是其他储藏方法的基础， 它利用低温条件下果蔬呼吸 减弱的特点， 延长果蔬的后成熟， 达到储藏目的； 真空保鲜是利用抽真空过程中带走 大量热量， 达到冷却目的， 同时也使果蔬的呼吸达到最低， 从而使果蔬的生命得到延 长； 化学保鲜是在果蔬表面形成均匀的保护层， 以抑制果蔬的呼吸， 达达储藏目的； 但是， 上述储藏保鲜果蔬的方法， 都有许多缺陷：  There are many methods for the storage and preservation of fruits and vegetables, such as low-temperature preservation, vacuum preservation, chemical preservation, etc. Low-temperature preservation is the original storage method and the basis of other storage methods. It takes advantage of the reduced breathing of fruits and vegetables under low temperature conditions to prolong fruits and vegetables. The post-maturation can achieve the purpose of storage; vacuum preservation uses a large amount of heat during the evacuation process to achieve cooling, and also minimizes the respiration of fruits and vegetables, thereby extending the life of fruits and vegetables; chemical preservation is the uniform formation of fruits and vegetables on the surface Protective layer to inhibit the breathing of fruits and vegetables to achieve storage purposes; however, the above methods of storing fresh fruits and vegetables have many defects:
低温保鲜， 只解决了果蔬的后成熟的温度问题， 还不能抑制果蔬的正常呼吸， 因 而只能解决部份只对温度敏感的果蔬储藏， 而且储藏的时间也不是很长； 真空保藏只 适用于小型容器， 因为大型库体做到真空度高， 是很困难的， 另外储存在真空容器内 的果蔬， 会流失大量水份， 对很多果蔬而言， 也就起不到保鲜效果了， 所以真空储藏 保鲜，使用范围有限；化学保鲜， 由于化学保鲜剂肯定会对环境和果蔬本身带来污染, 因此， 上述保鲜方法， 都存在缺陷。 实用新型内容  Low temperature preservation only solves the post-maturity temperature problem of fruits and vegetables, and cannot inhibit the normal breathing of fruits and vegetables, so it can only solve the storage of some fruits and vegetables that are only sensitive to temperature, and the storage time is not very long; vacuum preservation is only suitable for For small containers, it is difficult to achieve a high degree of vacuum in a large container. In addition, fruits and vegetables stored in a vacuum container will lose a large amount of water. For many fruits and vegetables, the preservation effect will not be achieved, so the vacuum Storage is fresh, and the range of use is limited; chemical freshness, because chemical fresheners will definitely cause pollution to the environment and fruits and vegetables, so the above freshness preservation methods have defects. Utility model content
为了解决前述果蔬储藏保鲜存在的问题，本实用新型提供一种气调保鲜储藏装 置， 其是在一长方形箱体的一头，分隔一小部份容积空间， 装有通风的百叶窗门， 内设一产生惰性气体的气调机， 经管道和阀体连接至另一端冷藏箱内， 另设一制冷 机与冷藏箱体内的冷风机连接，根据需要，还可增设乙稀脱除机和二氧化碳洗涤机， 分别经过管道和阀体连接至冷藏箱体内， 箱体内设置有加湿器， 被分隔箱体的两头 之间是密封的， 冷藏箱体有密封的门关闭。  In order to solve the aforementioned problems of fresh storage of fruits and vegetables, the present invention provides an air-conditioning fresh-keeping storage device, which is a rectangular box at one end, which divides a small volume of space, and is equipped with a ventilated shutter door. The air conditioner that generates inert gas is connected to the refrigerator at the other end via a pipe and a valve body. Another refrigerator is connected to the cooler in the refrigerator. If necessary, an ethylene removal machine and a carbon dioxide scrubber can be added. It is connected to the refrigerating box through a pipe and a valve body, respectively. A humidifier is provided in the box, and the two ends of the separated box are sealed. The sealed door of the refrigerating box is closed.
本实用新型的优点是， 由于采用惰性气体抑制果蔬的呼吸， 使果蔬维持在正常 生命活动前提下， 新陈代谢达到最低， 可以最大限度地延长果蔬的后成熟， 使果蔬 长时间保持新鲜状态， 据测试， 与低温保鲜储藏相比， 气调储藏保鲜， 可以延长一 倍以上保鲜时间。另外，气调储藏保鲜，适用范围大， 可适用于任何大小的库（箱) 体， 可用于公路、 铁路和海上运输的果蔬储藏保鲜。 附图说明 The advantage of the utility model is that because the inert gas is used to inhibit the breathing of fruits and vegetables, so that the fruits and vegetables are maintained under the premise of normal life activities, the metabolism is minimized, the post-maturity of fruits and vegetables can be maximized, and the fruits and vegetables are kept fresh for a long time. According to tests Compared with low-temperature fresh-storage storage, modified atmosphere storage and fresh-storage can extend More than freshness time. In addition, the modified atmosphere storage and preservation has a wide range of applications, and can be applied to any size of storage (box), and can be used for road, rail and sea transportation of fruits and vegetables storage and preservation.
