Description

Technical Field

[0001] The utility model belongs to the technical field of peach preservation, and particularly relates to a device for long-term preservation of peaches. Background Art

[0002] Peach is a fruit with crisp, sweet flesh and rich aroma. Its fruit is brightly colored and its flesh is rich in nutrients, such as soluble solids, sugar, vitamin C, inorganic salts, protein and crude fiber. Eating peach can not only promote the production of body fluids and relieve summer heat, but also stimulate the appetite and strengthen the spleen. It is an ideal fruit in the off-season of summer and autumn. Peaches are easily affected by the external environment during transportation and storage, which may cause corruption and deterioration of peaches and shorten their shelf life. Fresh-keeping boxes are needed to maintain the quality and taste of peaches, extend the shelf life and reduce losses.

[0003] However, the fresh-keeping boxes currently on the market generally have the problem of single function and are unable to automatically adjust the humidity inside the fresh-keeping boxes according to actual needs. A common practice is to simply spray some water on the surface of the peaches to increase the humidity before transportation or storage, but this method has obvious limitations. As time goes by, the sprayed water will quickly be absorbed or evaporated by the peaches, resulting in the humidity in the fresh-keeping box cannot be maintained within a stable and appropriate range, thereby failing to effectively extend the shelf life of the peaches. Utility Model Content

[0004] The purpose of the utility model is to provide a device for long-term preservation of peaches, which can automatically humidify the peaches in the fresh-keeping box, thereby extending the shelf life of the peaches.
