Problems solved by technology

[0003] At present, most of the post-harvest pre-cooling treatments for plums on the market only use a single aeration or water immersion cooling treatment, which makes the post-harvest cooling effect of plums unsatisfactory, and the existing technology can only pre-cool them. It is impossible to achieve film formation and preservation on the surface of plums during the pre-cooling process

Abstract

The invention relates to the technical field of film-forming fresh keeping of fruits and in particular relates to a water-air combined pre-cooling and film forming device for plum fruits. According tothe water-air combined pre-cooling and film forming device, a water storage cavity, a fruit box and a liquid storage groove are combined, and an air homogenizing cabin is arranged at the bottom of the fruit box; a spraying nozzle is arranged in the air homogenizing cabin; the spraying nozzle is communicated with the liquid storage groove, so that liquid containing a fresh-keeping agent, which issprayed through the spraying nozzle, is blown into the fruit box in an air conveying process of the air homogenizing cabin; the liquid is in contact with the fruits in the fruit box from bottom to topat an atomized state, and a film is formed on the surfaces of the fruits, so that atomization and film formation are realized and the fresh-keeping effect of the pre-cooled fruits is improved.

Description

technical field [0001] The invention relates to the technical field of film-forming and fresh-keeping of fruits, in particular to a water-gas combined pre-cooling and film-forming device for plum fruits. Background technique [0002] Plums are rich in nutrients and are generally harvested in the high temperature season from June to July every year. Due to the concentrated harvesting time, the market economic benefits of harvesting and selling plums are poor. Therefore, most growers consider storing plums for freshness and prolonging Shelf life, avoid the peak period of market sales, in order to pursue better economic benefits. However, the temperature of plums is high during the harvest period, and post-ripening is faster after harvesting, which greatly shortens the storage period of plums. After harvesting, store them at room temperature for no more than 7 days, and the plums will soften and deteriorate. Some researchers have studied the best environment for storing plums....
