Abstract

The invention discloses a freshness keeping device for fruits and vegetables in supermarkets, and belongs to the technical field of freshness keeping devices for fruits and vegetables. The freshness keeping device comprises a temperature detection unit, a humidity detection unit, a carbon dioxide concentration detection unit, a control unit, a temperature control unit, a humidity control unit, an ozone generation unit and a high-pressure electrostatic generation unit, wherein the high-pressure electrostatic generation unit comprises a direct-current high-voltage power supply, a positive-negative high-voltage filter circuit, a positive-negative ionic discharge electrode, a frequency producing module and a frequency selection module. According to the device disclosed by the invention, a high-voltage electrostatic field is adopted, so that the respiratory metabolism activity of the vegetables and the fruits is restrained, moisture content in the vegetables and the fruits is effectively maintained, and a freshness keeping effect is achieved.

Description

technical field [0001] The invention relates to a fruit and vegetable fresh-keeping device for supermarkets, belonging to the technical field of fruit and vegetable fresh-keeping devices. Background technique [0002] Supermarkets are increasingly becoming the first choice for housewives to purchase daily necessities due to the wide distribution of outlets, most of them are close to residential areas, and a complete range of commodities. In order to facilitate people's lives, many supermarkets have added counters for selling vegetables and fruits. Since the prices of vegetables and fruits in supermarkets are generally higher than those in vegetable markets, there is generally a surplus at the end of each day's business. However, the fresh-keeping time of vegetables and fruits is short, and it is inevitable to wilt, rot, and deteriorate for a long storage time, which in turn affects sales. [0003] The application number is 201410292960.X, and the application date is June 25...
