A method and device for predicting microorganisms in stored grain

Abstract

The invention discloses a method and a device for predicting stored grain microorganisms. A specific implementation of the method includes: collecting the temperature value and humidity value of the grain pile; calculating the moisture content of the grain according to the humidity value of the grain pile, and substituting the temperature value and moisture content of the grain pile and the storage time of the grain pile as prediction parameters into The prediction model in the form of an index is used to calculate the predicted value of stored grain microorganisms. This embodiment can timely and accurately predict the microbial growth of grain piles.

Description

technical field [0001] The invention relates to the technical field of food science. More specifically, it relates to a method and device for predicting stored grain microorganisms. Background technique [0002] At present, there are thousands of national and local grain depots in my country, which are distributed all over the country. The loss of stored grain in our country is mainly caused by rats, pests and microorganisms (fungi). The hazards of stored grain rats and pests have been effectively prevented. However, the hazards of stored grain microorganisms have not been resolved, and it has affected the security of my country's stored grains. [0003] At present, the detection of grain conditions in my country's grain depots mainly uses the method of measuring grain temperature to predict grain conditions. This method has the following shortcomings in grain situation prediction: 1) Grain is a bad conductor. method to predict the grain situation, there is a serious lag,...

However, the hazards of stored grain microorganisms have not been resolved, and it has affected the safety of my country's stored grains

[0003] At present, the detection of grain conditions in my country's grain depots mainly uses the method of measuring grain temperature to predict grain conditions. This method has the following shortcomings in grain situation prediction: 1) Grain is a bad conductor. method to predict the grain situation, there is a serious lag, so that the staff can not take measures to deal with it in time; 2) Some fungi produce very low heat during the growth process, such as Aspergillus gray aeruginosa, so it is impossible to use the current method of measuring grain temperature Comprehensive prediction of fungal hazards in stored grain; 3) The method of measuring grain temperature is seriously affected by environmental factors, and the accuracy is not high; 4) The measurement temperature range is small
