Description

Technical Field

[0001] This utility model relates to the technical field of agricultural products, and in particular to a high-frequency ion mist preservation treatment device for harvested apricots. Background Technology

[0002] Apricots, with their orange-yellow color, tender flesh, and sweet-sour taste, are widely loved by consumers. They are also rich in inorganic salts such as phosphorus, iron, potassium, and calcium, as well as various vitamins, offering good medicinal benefits. The apricot harvest season is relatively concentrated, typically occurring between June and July. As a climacteric fruit, apricots release large amounts of ethylene gas after harvesting, causing them to age rapidly, soften, and eventually rot. This makes them unsuitable for long-term storage, resulting in significant economic losses due to spoilage during storage and transportation.

[0003] Currently, there are not many post-harvest preservation methods for apricots. The patent "A Pre-cooling Device for White Apricots" (application number: 201721815191.2) uses a soft rot rate of 15% as the critical value, allowing apricots to reach their storage period after 50 days post-harvest; and uses an 80% marketable rate as the critical value, allowing apricots to have basic commercial value after 25 days of cold storage. This effectively reduces post-harvest water loss and desiccation of white apricots, resulting in plump, glossy apricots, delaying the ripening and yellowing process, and reducing the levels of amino acids and fats metabolized in the conversion of aroma precursors. The patent "A Modified Atmosphere Preservation Method for White Apricots" (CN201711399443.2) allows modified atmosphere packaging bags made of either PP or PET materials. The volume ratio of apricots to gas in the packaging bag is 1:3 to 1:6. The concentration of O2 gas in the modified atmosphere packaging mixture is 8% to 10%, and the concentration of CO2 gas is 2% to 4%. The preservation method provided can still achieve a good fruit rate of 80% after 25 to 30 days of storage, extending the shelf life of white apricots by 10 to 15 days. The patent "An Apricot Preservation Device with Intelligent LED" (CN202321126131.5) describes a new invention that uses LED light to preserve apricots. The temperature and humidity display screen and control panel can obtain the LED light dose and the temperature and humidity inside the box in real time to maintain constant light, temperature and humidity inside the box, thereby preserving apricots for a long time.

[0004] Using non-toxic and harmless safe preservatives is an important method for post-harvest preservation of apricots. However, traditional preservative treatment methods have certain drawbacks. The treated liquid tends to accumulate at the bottom of the apricots, causing them to rot. At the same time, the preservative recovery efficiency is low, resulting in waste.

[0005] Therefore, there is an urgent need for a high-frequency ion mist preservation treatment device for apricots after harvesting. Utility Model Content
