Problems solved by technology

The main mode of action of essential oils is fumigation and contact treatment. The fumigation takes a long time and does not directly contact the fruit, which avoids the negative effects of multiple operations on the fruit. Therefore, it is especially suitable for blueberries, sweet cherries, strawberries, etc. Fruits with thin peel and delicate flesh, but due to the high volatility of essential oils, two extreme phenomena are prone to occur. One is the phytotoxicity caused by high concentration or short-distance vertical action, and the other is that the low concentration will not achieve antibacterial effect. Therefore, How to continuously and stably volatilize essential oils and evenly act on fruits has become an urgent problem to be solved. Therefore, it is particularly important to develop specific loading forms and supporting devices for essential oil fumigation; Carbon dioxide-resistant fruit, the effect of spontaneous air conditioning will be more obvious
Therefore, essential oil fumigation combined with spontaneous modified atmosphere technology is particularly suitable for the postharvest preservation of these three fruits, but there are no detailed reports on this aspect of research

Abstract

The invention discloses an essential oil application device and application method for small fruit controlled atmosphere storage and shelf preservation. The device comprises an outer shell body, fumigation trays and a non-woven fabric, wherein the fumigation trays are arranged in the outer shell body, the non-woven fabric is attached to a side wall in the outer shell body and is loaded with an essential oil, a side of the outer shell body is open and provided with a sealing side cover, the fumigation trays can be separated from the outer shell body by pulling, each fumigation tray is providedwith a plurality of independent fumigation chambers, a partition is arranged between the adjacent fumigation chambers, an outer edge of each fumigation tray is higher than the partition, an arc-shapedopening is arranged on the partition between the vertically adjacent fumigation chambers, the diagonally disposed fumigation chambers are provided with anti-pressure protrusions on opposite corners,a side edge of the fumigation chamber, the anti-pressure protrusion and the arc-shaped opening jointly form a vertical ventilation passage, the side edge of the fumigation chamber, the anti-pressure protrusion and the partition jointly form a lateral ventilation passage, and a side wall of each fumigation chamber is uniformly provided with holes. The device can not only delay a respiratory processof fruits, meet the requirements of inhibiting pathogenic bacteria, but also achieve an accurate, stable, uniform and effective essential oil fumigation effect.

Description

technical field [0001] The invention relates to the technical field of fruit storage and preservation, in particular to an essential oil applicator and application method for controlled atmosphere storage and shelf preservation of small fruits. Background technique [0002] In recent years, with the continuous expansion of the planting scale and industrialization of emerging small and rare fruit varieties such as blueberries, sweet cherries, and strawberries, small and rare fruits have become an important part of the country to adjust the agricultural planting structure, promote regional economic development, and drive farmers to become rich and develop. One of the fastest emerging industries. Among them, blueberry, as the third-generation golden fruit, has attracted the attention and favor of consumers because of its unique flavor, rich nutrition and various functional characteristics. King of Berries". China's blueberry industry has become the fastest-growing emerging fr...
