Device and method capable of prolonging shelf life of fruits

Abstract

The invention provides a device and method capable of prolonging the shelf life of fruits, and belongs to the technical field of fresh keeping of fruits. The device comprises a storage cabinet, a plurality of moving mechanisms, a sterilization box, a steam spraying mechanism and an air inlet system, wherein a plurality of cavities are formed inside the storage cabinet; a moving cabin is rotatablyarranged in each cavity; the plurality of moving mechanisms are arranged in the corresponding cavities; each moving mechanism can drive the corresponding moving cabin to do reciprocating movement; thesterilization box is arranged in the inner cavity arranged at the back side of the storage cabinet; coil pipe assemblies are arranged in the sterilization box; the coil pipe assemblies communicate with the corresponding cavities; the steam spraying mechanism is arranged at one side of the sterilization cavity; the air inlet system is arranged at one side of the steam spraying mechanism, and communicates with a mist outlet pipe of the steam spraying mechanism; the mist outlet pipe of the steam spraying mechanism is detachably connected with the coil pipe assemblies; and a sterilization lamp group is arranged on the inner wall of the sterilization box. In a mode of combining controlled atmosphere and a preservative and fresh-keeping technology, the shelf life of the fruits can be prolonged;the commodity rate is improved; the cost is low; the use is convenient; and the device and the method are suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of fruit preservation, and in particular relates to a device and method capable of prolonging the shelf life of fruits. Background technique [0002] Fruits can provide rich nutrients for our daily life. Therefore, the supply and demand of fruits is very large. However, due to the high water content of fruits, they are very easy to lose their freshness for a period of time after they are ripe and picked, resulting in reduced quality and shortened shelf life. Reduced merchandise rate. The shelf life refers to the time when the fruit is placed on the shelf in the sales place for sale after the end of the suitable storage conditions. When the time comes, the shelf must be removed, that is, the shelf life is over. [0003] At present, there are many ways to extend the shelf life of fruits, such as spraying preservatives, modified atmosphere preservation, biological preservation, ozone preservation, irradiation ...

AI Technical Summary

Problems solved by technology

If the preservative is sprayed on the surface of the fruit, it will be difficult to remove the preservative when the fruit is eaten, and some preservatives will cause certain harm to the human body after eating

However, if the fruit is refrigerated to keep the fruit in a low-temperature state for a long time, more energy is required and the cost is higher; and some fruits will form tissue damage in a long-term low-temperature environment, and physiological metabolic disorders will occur when they are just out of the refrigerated environment. Drastic changes, resulting in shorter shelf life and lower commodity rates

The blue and red light required by the irradiation technology can prolong the shelf life of the fruit, but long-term viewing can cause damage to the eyes

The ozone required by ozone technology is easy to cause damage to the environment, which is not conducive to environmental protection

[0004] However, there is no attempt to combine several methods in the existing methods to extend the shelf life and maximize the commodity rate while reducing costs.
