A low-temperature plasma generating device and method for keeping fruits and vegetables fresh

Abstract

The present application discloses a low-temperature plasma generating device and method for keeping fruits and vegetables fresh, which are used to solve the problem that the existing devices using low-temperature plasma to sterilize fruits and vegetables cannot efficiently and stably generate low-temperature plasma. The device includes: a low-temperature plasma generation module; the low-temperature plasma generation module includes a barrier dielectric plate, a rhombic mesh electrode, and a flat electrode; the first surface of the rhombus mesh electrode is in contact with the first side of the barrier dielectric plate, and the first surface of the flat electrode The surface is in contact with the second side of the blocking dielectric plate; wherein, the length of the first diagonal of several rhombus grids included in the rhombic mesh electrode is 1 mm, and the length of the second diagonal is 2 mm; the material of the blocking dielectric plate is nitrogen Aluminum AlN. In this application, a barrier dielectric plate made of AlN and a rhombic mesh electrode with a rhombic grid diagonal of 1mm×2mm are selected to ensure that the low-temperature plasma generator can efficiently and stably generate low-temperature plasma.

Description

technical field [0001] The present application relates to the technical field of fruit and vegetable preservation, in particular to a low-temperature plasma generating device and method for fruit and vegetable preservation. Background technique [0002] Compared with the traditional fruit and vegetable preservation technology, the application of low-temperature plasma for fruit and vegetable preservation is a non-thermal processing technology that has emerged in recent years. Its temperature is close to room temperature, which can kill microorganisms attached to the surface of fruits and vegetables and degrade the ethylene gas synthesized by fruits and vegetables. , Inhibit the metabolism of fruits and vegetables, has the advantages of high efficiency, no pollution, no residue, no heat damage, significant antibacterial effect, etc., and has a very good application prospect. [0003] In recent years, with the rise of the use of low-temperature plasma for fruit and vegetable p...
