Embodiment Construction

[0014] The specific implementation will be described below in conjunction with the accompanying drawings and three main working schemes of the device of the present invention.

[0015] (1) Reduce moisture, sterilize, prevent mold, prevent insects and ventilate

[0016] Such as figure 2 As shown, set the target value of the temperature and humidity sensor controller (7) and the standard time value in the intelligent control system (4), the relative humidity of the air in the warehouse will be adjusted to be lower than the equilibrium relative humidity of the processed grain moisture; Open fan (8), air supply door (9) and fresh air door (11); open high-power ozone generating system (1) and air drying subsystem (6). The device automatically runs to the humidity setting target value to balance the dryness; the device automatically stops when it runs to the specified time. The device can reduce the moisture content of the grain while reducing the amount of bacteria in the grain....

Abstract

The invention provides an intelligent ozone quality / freshness keeping device for grain storage and transportation process. The device consists of a high-power ozone generation system, a temperature / humidity measurement and control system, a direct / loop air supply system and an intelligent control system. The device, based mainly upon the characteristics of ozone, is used for loop fumigation, quality regulation or drying of stored grains by taking air as carrier, in order to change the composition of gas ingredients and the temperature / humidity in barn, destroy the growth environment of pests and mildews, prohibit physiological respiration of grains, and realize mildew prevention and sterilization, moth prevention and pest elimination, quality regulation and freshness keeping and quality keeping and drying, thus the purpose of storing grains in an economical, practical and green way is achieved. The device, which is different from the previous single-grain-storage technology, not only has the functions of preventing mildew and moth and keeping quality, but is also capable of in-barn drying, quality regulation and freshness keeping. The device can implement the quality / freshness keeping storage of grains with higher moisture, enhance the quality of stored grains and reduce the decrement loss of moisture. The device is safe, green and environmentally-friendly, and can degrade mycotoxin and organophosphorus pesticide residues in grains without causing secondary pollution to grain quality as well as storage and transportation environments.

Description

1. Technical field [0001] The invention relates to a technical device used in the grain storage and transportation process. More specifically, it relates to a technique of using ozone to prevent insects, mildew, temper and preserve freshness, and preserve quality and dry grain storage. 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. Considerably increase the cultivated area of ​​land by 15 million to 20 million mu. Due to my country's ba...
