Problems solved by technology

Due to the large warehouse and deep grain pile, there are still disadvantages such as poor ventilation uniformity, long operation time, and large energy consumption. Therefore, it is very easy to cause insects, heat, humidity, mold, and agglomeration in the grain pile. The method of ensuring the quality of stored grain by means of ventilation and cooling, which can effectively detect and treat microorganisms in stored crops, has never been reported.

Embodiment 1

[0030] Embodiment 1: (storage agricultural crop is Jiangxi paddy sample)

[0031] The present invention arranges 7 points per 10 square meters, and after the fixed-point sampling is carried out with the sampling device 7 from the upper, middle and lower layers, the rapid microbial detection instrument is used to analyze, detect and judge, and finally use a multi-functional processing device to detect and judge when the over-standard The sample point of the sample was treated with ozone; again, it was analyzed and judged by the rapid microbial detector, and the above steps were repeated until the microbial activity of the sample sample was below 200 activity units. A total of 21 samples were taken this time.

[0032] The upper layer sampling point of the present invention refers to that the distance from the sampler probe 7 to the crop pile surface is 40 centimeters.

[0033] The lower sampling point of the present invention refers to that the distance from the sampler probe 7...

Embodiment 2

[0044] Embodiment 2: (the crops in the storage bin are rapeseed)

[0045] The present invention arranges 5 points per 10 square meters, and after the fixed-point sampling is carried out with the sampling device 7 from the upper, middle and lower three layers, the rapid microbial detection instrument is used to analyze, detect and judge, and finally use a multi-functional processing device to detect and judge when the over-standard The sample point of the sample was treated with ozone; again, it was analyzed and judged by the rapid microbial detector, and the above steps were repeated until the microbial activity of the sample sample was below 200 activity units. A total of 15 samples were taken this time.

[0046] The upper layer sampling point of the present invention refers to that the distance from the sampler probe 7 to the crop pile surface is 20 centimeters.

[0047] The lower sampling point of the present invention refers to that the distance from the sampler probe 7 t...

Embodiment 3

[0057] It can be seen from the above table that the total microbial activity and the number of mold spores in rapeseed treated with ozone are lower than those before treatment. Embodiment 3: (stored crops are tobacco)

[0058] The present invention arranges 5 points per 10 square meters, and after the fixed-point sampling is carried out with the sampling device 7 from the upper, middle and lower three layers, the rapid microbial detection instrument is used to analyze, detect and judge, and finally use a multi-functional processing device to detect and judge when the over-standard The sample point of the sample was treated with ozone; again, it was analyzed and judged by the rapid microbial detector, and the above steps were repeated until the microbial activity of the sample sample was below 150 activity units. A total of 15 samples were sampled this time.

[0059] The upper layer sampling point of the present invention refers to that the distance from the sampler probe 7 to...

Abstract

Samples are taken from three layers: upper, middle and lower in at least 5 points per 10 m2 by using pointed metal tube. Quick microbe detector analyzes judgment of detection. Multifunctional processing device lets ozone into unqualified points. Judgment of detection is operated again. The said procedure is repeated till microbial activity in samples is lower than 200 active units. Features of the invention are: short operation time, small energy consumption.

Description

Technical field: [0001] The invention relates to a method for detecting and treating microorganisms, in particular to a method for detecting and treating microorganisms in bulk crop storage. Background technique: [0002] Due to the characteristics of small microorganisms, rapid reproduction, wide distribution, easy cultivation, and favorable mutation, microorganisms will multiply at an alarming rate under appropriate temperature and humidity. In addition, the thermal conductivity of food is poor, and microbial metabolism will generate a lot of heat, etc. Objective factors, pests, mycotoxins, stored crop germination and other hazards will follow. Therefore, in the storage process of bulk grain, it is necessary to detect, judge and treat microorganisms, because this is directly related to the quality of the stored crops. Good or bad, if the microorganisms cannot be reasonably controlled, it will cause a series of serious hazards such as heat generation, reduced scattering, ag...
