Modified Atmosphere Refrigerator - QT160, with microelectronics technology, is for making preservation experiment on fruits, vegetables, flowers and plants in modified atmosphere conditions, and keeps them fresh by controlling the concentration of O2, N2, CO2, and C2H4 and the temperature and humidity in the boxes. It is widely used in industries of microorganisms, environmental, food, research institute and so on. 

    Features/Advantages

    Hardware and software

    • Computer controlling and runs fully automatically.
    • Configured with: transparent window, sterilization system, built-in headlight and self-occlusive design cabinet.
    • Can automatically record the respiratory status of fruits and vegetables and check data handily.
    • Real color touch screen displays the parameters and results visually.
    • With software, real time monitor and continuous record of gas composition, temperature and humidity.
    • Imported precise sensors ensure wide test range and high accuracy.
    • Cooling system uses scroll compressor, with high performance and little noise.
    • With ethylene removing device.
    • Online analysis system is optionally available.

    Temperature control

    • Temperature controlling system adopts scroll compressor which makes stable performance and low noise.
    • Program stepping temperature controlling system controls the temperature precisely, evenly and constantly, without rigid mechanical contacts and with long lifetime.

    Humidity control

    • Advanced Double pressure humidifier provides large humidification range and stable humidity. Can humidify for a long time without getting hot.
    • Automatically humidifies after setting the humidity parameters, reach the set humidity and stay at that humidity constantly.

    Gas control

    • Automatically control the concentration, temperature and humidity of the gases.
    • With ethylene eliminating device and gas substituting pump, controls the concentration of ethylene effectively.
    • Accurate flow controller (resolution ratio: 0.01ml/min) controls the gas flow exactly.
    • Auto replacement of gas, fast removal.
    Theory/Method

    In a closed system, with a variety of adjusting methods to obtain gas component constituents different from that of normal atmospheric gas, microbial life activities resulting in product deterioration are inhibited. The key of atmosphere preservation technology is to adjust the gas concentration. In addition to the concentration and component constituents of the gas, two core controlling conditions: temperature and relative humidity should also be considered. Not only pay attention to their individual impact, but also emphasize on the combined effects of the various conditions of the environment overall.

    The Modified Atmosphere Refrigerator can simulate above conditions to find out the optimal preservation conditions of different products correspondingly.
