Intelligent nitrogen-enriched ozone atmosphere-controlling quality-guaranteeing freshness-preserving method and device for foodstuff storage and transportation process

Abstract

The invention provides an intelligent nitrogen-enriched ozone atmosphere-controlling quality-guaranteeing freshness-preserving method and an intelligent nitrogen-enriched ozone atmosphere-controlling quality-guaranteeing freshness-preserving device for foodstuff storage and transportation process. The device consists of a nitrogen and oxygen separation system, an ozone generation system, a temperature and humidity and gas concentration test control system, a direct circulation air supply system, a 360-degree uniform flow atmosphere control air supply system, and an intelligent control system. According to the method and the device, stored foodstuff is subjected to circulation atmosphere control, quality adjustment and freshness preservation or quality preservation drying treatment by utilizing the characteristics of nitrogen and ozone and taking air as a carrier, gas composition and temperature and humidity in a barn are changed to damage the growing environment of pests and molds, and the physiological respiration of the foodstuff is adjusted, so that mold resistance and sterilization, moth resistance and insect disinfestation, quality adjustment and freshness preservation, quality preservation drying and safe detoxication can be realized, and aims of economy and practicability and environment-friendly foodstuff storage are fulfilled. Compared with the conventional foodstuff preservation technology, the method and the device not only have the functions of mold and moth resistance and quality keeping, but also have the functions of quality preservation drying and quality adjustment and freshness preservation. By the method and the device, the functions of keeping quality and preserving freshness of the stored foodstuff with over high water content can be realized, the quality of the stored foodstuff can be improved and water content decrement loss is reduced. The device is environment-friendly, and mycotoxins and organic phosphorus pesticide residues in the foodstuff can be degraded, and the device and the method do not cause secondary pollution to the foodstuff and storage and transportation environment.

Description

1. Technical field [0001] The invention relates to a method and device used in grain storage and transportation. More specifically, it relates to a green ecological environment-friendly grain storage technology that utilizes nitrogen and ozone to prevent mildew and sterilize, prevent moth and kill insects, condition and preserve freshness, preserve quality and dry, and safely disinfect. 2. Background technology [0002] According to the results of a sample survey of post-harvest grain loss in 574 counties in 22 provinces across the country by China Agricultural University, the grain loss rate in rural areas in my country is 10% to 18%, and about 85 million tons of grain are wasted after harvesting in the country every year. If storage, processing, and transportation conditions can be improved, calculated by reducing the loss rate by 5%, the annual loss can be reduced by 15 million to 20 million tons. Calculated at 2,000 yuan per ton of grain, it is 30-40 billion yuan. Cons...
