Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable fresh-keeping, in particular to a cold chain storage and fresh-keeping device for fruits and vegetables. Background Art

[0002] Cestrum nocturnum is a plant with unique edible value and medicinal efficacy. Its flowers not only bloom at night, emitting a charming fragrance, but also are regarded as a precious ingredient in some regions of Asia, especially in Cantonese cuisine. The flower buds of Cestrum nocturnum are picked before blooming to maintain their best flavor and nutritional value. This flower can be enjoyed through various cooking methods, such as stir-frying, making soup or cold dressing, and each method can bring out the unique flavor of Cestrum nocturnum.

[0003] Since the shelf life of Cestrum nocturnum is relatively short and it has high requirements for storage conditions, changes in temperature, humidity and gas composition may all affect its quality. Therefore, in order to maintain the freshness of Cestrum nocturnum and extend its shelf life, a cold chain storage and fresh-keeping device for fruits and vegetables is usually needed. This device can provide a suitable temperature and humidity environment, and may also adjust the gas composition, such as reducing the oxygen concentration and increasing the carbon dioxide concentration, so as to slow down the respiration, reduce the consumption of nutrients, and maintain the color and taste of the flowers.

[0004] Taking Cestrum nocturnum as an example, although the existing fresh-keeping device effectively extends the fresh-keeping time by placing ice packs inside the vegetables to reduce the temperature, this method may cause physical damage to Cestrum nocturnum, such as bruising, which not only affects its appearance quality but also may reduce its market value. In addition, the installation method of traditional ice packs also limits the uniform distribution of the low-temperature fresh-keeping effect, and the Cestrum nocturnum at the inner edge of the fresh-keeping device does not receive sufficient low-temperature protection, resulting in an unsatisfactory fresh-keeping effect in these areas and having certain limitations in use.

[0005] Based on this, we propose a cold chain storage and fresh-keeping device for fruits and vegetables to solve the above-mentioned problems. Summary of the Utility Model
