Technical Field
[0001] The utility model relates to the technical field of fresh-keeping equipment, and more specifically, to an essential oil application device for shelf fresh-keeping. Background Art
[0002] In recent years, with the continuous expansion of the planting scale and industrial development of emerging small and rare fruit varieties such as blueberries, sweet cherries, and strawberries, small and rare fruits have become a new and rapidly developing industry for adjusting the agricultural planting structure, promoting regional economic development, driving farmers to get rich across the country. Among them, blueberries, as the third-generation golden fruit, have attracted much attention and favor from consumers due to their unique flavor, rich nutrition, and diverse functional characteristics. They are recommended by the Food and Agriculture Organization of the United Nations as one of the five healthy foods and are known as the "king of berries". The blueberry industry in China has currently become one of the fastest-growing new fruit tree industries in China, with an average annual growth rate of the planting area of more than 150%. Blueberries, sweet cherries, and strawberries have small single fruit weights, thin skins, and juicy flesh, and are easily damaged by mechanical injuries such as bumps and bruises during harvesting, storage, and transportation. In addition, their mature harvesting periods are mostly in summer, and the respiratory intensity and physiological metabolism of the fruits after harvesting are enhanced, resulting in extremely poor storability. Quality deterioration phenomena such as fruit softening, fruit stalk depression, and easy infection by pathogenic bacteria and rotting occur, seriously restricting the sustainable development of the industry. Therefore, it is imperative to research and develop the key technologies for post-harvest storage and shelf-life fresh-keeping of small and rare fruits, which plays an important role in promoting the development of the industry.
[0003] In recent years, plant essential oils have been widely recommended as the most promising natural products for inhibiting harmful microorganisms and improving the antioxidant capacity of fruits and vegetables themselves. They have high biological safety, biodegradability, and the ability to resist the resistance of pathogenic microorganisms. The main action modes of essential oils are fumigation and contact treatment. The fumigation time is relatively long and does not directly contact the fruits, avoiding the negative effects caused by multiple operations on the fruits. Therefore, it is especially suitable for fruits with thin skins and delicate flesh such as blueberries, sweet cherries, and strawberries.
[0004] The fumigation trays currently used are generally installed on the fruit and vegetable shelves or placed on the ground between the fruit and vegetable shelves. However, obviously, in these two ways, the closer to the fumigation tray, the higher the concentration of essential oil in the air, and the farther away from the fumigation tray, the lower the concentration of essential oil in the air. The level of essential oil concentration has a great impact on the fresh-keeping of fruits and vegetables, which will cause the shortening of the fresh-keeping time of fruits and vegetables in the area with a lower essential oil concentration. The utility model proposes a new solution to the above problems. Content of the Utility Model
