Device for keeping fresh by controlled atmosphere combined with light

Abstract

The invention discloses a device for keeping fresh by controlled atmosphere combined with light, aiming to provide a device for effectively inhibiting the respiratory intensity of fruits and vegetables through the combination of weak light and gas components under the condition of weak light, which is beneficial to prolonging the shelf life of fruits and vegetables. The device comprises a box, a temperature and humidity regulation system, a gas composition regulation system, a light regulation system and an exhaust unit; the gas composition regulation system includes a nitrogen making machine,a gas composition acquisition unit, a gas transportation unit and a gas analyzing unit, and the nitrogen making machine is communicated with the inside of the box; the light regulation system includes a light parameter acquisition unit, LED modules and an LED controller, the LED modules include a red light module and a blue light module which are installed at the top of the box, and the total light intensity of red light of the red light module and blue light of the blue light module are 8-15 mu mol m<-2> s<-1>. The respiratory intensity of the fruits and vegetables is effectively inhibited through comprehensive control, the storage period and preservation period of the fruits and vegetables are prolonged, and more convenient adjustment operation is achieved.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, and more specifically, relates to a controllable atmosphere-modulated light integrated fresh-keeping device. Background technique [0002] The core of fruit and vegetable storage technology is to maintain slow respiration that can maintain normal physiological activities, reduce the consumption of organic matter and make fruits and vegetables still have good quality and commerciality after storage. [0003] The current fresh-keeping devices focus on the optical fresh-keeping and modified-atmosphere fresh-keeping of specific varieties, and do not have universality. Moreover, due to the interaction between multiple parameters, a small change in one of the parameters can cause a change in the storage environment, thereby affecting the fresh flavor and nutritional value of fruits and vegetables, and affecting the shelf life of fruits and vegetables.
