Problems solved by technology

Traditional photolysis instruments (or light aging chambers) usually use xenon lamps and fluorescent lamps as simulated light sources. These light sources have short service life, high power consumption, and large heat generation. They cannot be used continuously for a long time, and the simulation of natural light is not enough.

Abstract

The invention discloses a device for simulating illumination deterioration of food components. The device comprises a box body (1) provided with circulating ventilation equipment, and switchable LED lamp panels (5), wherein the box body (1) is collocated with heating equipment (7), refrigeration equipment (8), a humidifier (9), a dehumidifier, oxygen supply equipment (10), nitrogen supply equipment (11) and a sensor component; at least two LED lamp panels (5) are arranged in the box body (1) and each LED lamp panel (5) consists of a plurality of LED lamp beads (12); a numerical control panel (2) and a light intensity adjusting device (6) are arranged on the box body (1), and each LED lamp panel (5) is electrically connected with the light intensity adjusting device (6) respectively; and a heat insulation layer is arranged on the inner wall of the box body (1) at first, and then a light-reflecting layer is arranged on the inner wall of the box body (1). By use of the device, an illumination deterioration condition of the food components can be simply and efficiently simulated.

Description

technical field [0001] The invention relates to the technical field of light deterioration devices, in particular to a device for simulating light deterioration of food components. Background technique [0002] In the process of food storage, light plays an important role in the deterioration and degradation of food components, and in the process of light deterioration, it is easy to interact with oxygen, temperature, humidity and other factors to accelerate the reaction of oxidation and deterioration. Therefore, while simulating well-enhanced natural light irradiation, it is particularly important to effectively control other deterioration factors for the smooth progress of food ingredient light deterioration experiments. However, existing equipment cannot meet the above requirements. Traditional photolysis instruments (or light aging chambers) usually use xenon lamps and fluorescent lamps as simulated light sources. These light sources have short service life, high power ...
