Abstract


In this paper , on the basis of the research the advantages and disadvantages of the status quo of fresh fruits and vegetables and a variety of preservation methods , based on the characteristics of ozone fresh fruits and vegetables , an important part of the equipment of the new ozone fresh fruits and vegetables to the study and design of the impact its reliability , stability optimization and explore the depth and efficiency issues , and ultimately developed a stable performance of the ozone fruit and vegetable preservation device , and successfully applied to the fruit and vegetable storage . The paper focuses on the buffer circuit and output coupling capacitors affect the ozone generator power reliability problems , and by means of theoretical calculations and experimental studies to optimize the parameters selected under the load conditions , and a detailed analysis of the changes in the discharge tube temperature and control the chip temperature the impact of the discharge efficiency and the ozone generator . On this basis , design preservation equipment ozone generator required switching power supply and high-frequency step-up transformer . Secondly, the design of the accurate sampling circuit of the device , the protection circuit and the alarm circuit . Finally, based on the above research proposed open-loop control ozone put and successfully applied to the storage of cherries , good storage . Reliable the article designs ozone fruit and vegetable preservation device performance , resulting in higher ozone efficiency , and cost-effective to meet the design requirements and through the practical application of user praise .
