Problems solved by technology

[0002] Due to their own physiological characteristics, fruit and vegetable foods are extremely intolerant to storage. After a short period of storage, the fruit and vegetable peels and pulp may rot, which greatly affects the operation of businesses and consumers' purchase behavior. How to ensure food value is a major problem
At present, chemical methods are mainly used for fresh-keeping of fruits and vegetables. Chemical methods mainly use chemical reagents or fresh-keeping film to keep fresh. However, the existing coating preservatives contain chemical substances that are harmful to human health, and the fresh-keeping effect is not satisfactory.

Abstract

The invention relates to a device and method for maintaining the freshness of fruits and vegetables. The device comprises a shell and an upper cover, wherein a switch is arranged on the outer side of the upper cover, a power interface is arranged at one end of the switch on the outer side of the upper cover and is used for connecting with a direct current battery, and the other end of the inner side of the upper cover is sequentially connected with a high-frequency oscillation source device and an effective factor generator; the high-frequency oscillation source device is used for generating high-frequency alternating current to enable the effective factor generator to generate O3 and negative ions, and the O3 and negative ions circulate in the shell for maintaining the freshness of the fruits and vegetables during long-distance transportation; and the effective factor generator comprises O3 generators arranged in mirror symmetry and internal and external electrodes connected between the O3 generators.

Description

technical field [0001] The invention relates to a device and a method for maintaining freshness of fruits and vegetables. Background technique [0002] Due to their own physiological characteristics, fruit and vegetable foods are extremely intolerant to storage. After a short period of storage, the fruit and vegetable peels and pulp may rot, which greatly affects the operation of businesses and consumers' purchase behavior. How to guarantee the edible value is a major problem. At present, chemical methods are mainly used for fresh-keeping of fruits and vegetables. Chemical methods mainly use chemical reagents or fresh-keeping film with fresh-keeping effect to keep fresh. However, the existing coating preservatives contain chemical substances that are harmful to human health, and the fresh-keeping effect is not satisfactory. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a device for maintaining freshness of f...
