Description

Barn automatic de-worm sterilization non-toxic technology

The invention relates to a barn automatic de-worming sterilization non-toxic technology, in particular to a technical method for replacing the sterilization and sterilization of traditional corn flour, grain and agricultural product storage with chemical agents for disease vector control.

Investigate, the current vector control technologies for barns, grain silos, and agricultural products (such as flour) are roughly as follows.

The first type is cleared by human physics, mainly through the entry of workers into the barn to remove pests and residual grains. There is no chemical hazard to the grain by manpower cleaning the barn, but the disadvantages are: (1) It is inevitable that some eggs and insects cannot be cleaned up by manpower cleaning the barn, so these insects will grow in the barn after a few weeks; (2) The biggest problem in the way of manpower clearance is that the barn in order to protect the grain, grain flour, and agricultural products does not deteriorate, and the air mobility of the storage space is not high. Therefore, the operator may have an accident such as lack of oxygen; (3) The manpower clearance method is limited to the barn and is not suitable for the grain bin (safety factor).

The second type is to use chemical agents to control the disease vector. The environmental protection drugs and pesticides of the Environmental Protection Agency are used, and a certain proportion is sealed in the closed warehouse for 7 to 30 days. After the toxicity of the drug declines to the concentration that does not harm the human body, The first grain (powder) material is put into the warehouse, and the grain (powder) material is used for clearing, and the valley (powder) which may be contaminated is completely discarded, and the second edible material is used as the normal edible valley (powder). The use of low toxicity in the warehouse to inhibit the growth of vector pests in the body for 3 to 6 months, to achieve the purpose of pest control preservation of the valley (powder). However, the disadvantages of using chemical agents to control disease vectors are as follows: (1) Each time the chemical agent method is implemented, it must be stopped for 7 to 30 days, and the construction period is longer; (2) although the prevention of disease vectors and insects can last for about one year, in other words, That is, the toxin residue is longer, and there is concern about food safety; (3) This method is not allowed on organic certified products.

There is also a control method for injecting nitrogen into the barn, which mainly uses suffocating elimination of the vector, but the gas of nitrogen is light in weight, and when the residual oxygen is lowered, the disease medium and the worm move to the lower half of the barn, so The effect is limited.

The main object of the present invention is to provide a barn automatic sterilization and sterilization non-toxic technology, which mainly uses nitrogen gas combined with carbon dioxide to be injected into the storage space of the barn, and reduces the residual oxygen content in the barn to less than 1.8%, thereby achieving prevention and treatment of the disease in the barn. The efficacy of the media, and the preservation of cereals, flour, and agricultural products are safe and non-toxic.

The method for achieving the above object comprises the following steps: Step 1: emptying the storage space of a barn; Step 2: injecting a gas of mixed nitrogen and carbon dioxide into the barn; Step 3: mixing the nitrogen gas through the air inlet of the barn And the mixed gas of carbon dioxide, the powder and the worm body on the wall of the storage space of the barn are blown off during the spraying process; Step 4: the storage space of the barn is sterilized by nitrogen and carbon dioxide; Step 5: Sealing The storage space is 1 to 24 hours, while blocking gas ingress and static sterilization for any species in the barn.

In the foregoing embodiment, the optimal conditions for controlling the vector are: 40% to 81% of nitrogen, 19% to 60% of carbon dioxide, and 1.8% or less of residual oxygen, and the state of sealing the barn in this state is 40 minutes. The above can achieve the effect of prevention and control, and then the grain and the grain powder can be injected into the barn after the gas (material) is opened, so that the control method of the invention can be implemented on the barn as long as there is a feed gap, and the quality of the barn can be ensured. The grain, grain and agricultural products shipped from the barn are non-toxic and safe.

In the foregoing embodiment, a gas inlet for injecting mixed nitrogen and carbon dioxide is disposed above the barn, which mainly provides a mixed gas to enter, and another feature is that the mixed gas of nitrogen and carbon dioxide is mixed through the air inlet. During the spraying process, the powder and the worm body on the wall of the storage space of the barn are blown off, thereby maintaining the product quality in the barn.

In the foregoing embodiments, the use of nitrogen and carbon dioxide has a non-toxic property, which changes the permeability of any cell after the addition of carbon dioxide, causes cell abnormalities of the worm body, accelerates the death effect of the worm in the suffocation space, and further carbon dioxide and The atmospheric moisture in the storage space further generates a chemical reaction to form carbonic acid, on the one hand, the water vapor content is reduced (ie, dehumidification), and on the other hand, the decrease in the pH value in the storage space makes the mold unable to survive to the advantage of preventing mold.

In order to enable the reviewing committee to have a better understanding and recognition of the features and characteristics of the present invention, the following preferred embodiments are illustrated with the following description: Please refer to Figures 1 to 5 for automatic barn sterilization of the barn of the present invention. Non-toxic technology mainly includes the following steps:

Step 1 S1: The storage space 11 of a barn 10 is emptied, and the technique of the present invention is implemented in a state where the barn 10 is empty, so that the suffocating effect of the disease vector in the storage space 11 in the barn 10 can be sufficiently produced.

Step 2: S2: Injecting a gas A of mixed nitrogen and carbon dioxide into the barn 10, mixing the nitrogen gas with carbon dioxide by a nitrogen generator and a carbon dioxide gas and a gas mixer, and passing through the air inlet 12 of the barn 10 The mixed gas A is injected into the storage space 11.

Step 3: S3: blowing the gas and the worm body W on the wall of the storage space of the barn during the spraying process through the air inlet 12 of the barn;

Step 3: S4: The gas A mixed with nitrogen and carbon dioxide is used to chemically react the suffocating insecticide W and the carbon dioxide in the storage space 11 of the barn 10 with the atmospheric moisture in the storage space 11 to convert the carbon dioxide into the carbonic acid, thereby reducing the storage space. The moisture inside (ie, dehumidification), on the other hand, carbonic acid production reduces the pH value in the barn 10, making the mold difficult to survive.

Step S5: sealing the storage space for 1 to 24 hours while blocking the entry of the gas A, and performing static sterilization on any species in the barn.

The grain and cereal powder preserved by the present invention are non-toxic and highly safe, comply with the regulations of organic certified foods, and the disease medium does not easily survive in the storage space 11, and the quality of the grain and the flour can be maintained.

In the above-mentioned embodiment, the optimal conditions for controlling the vector are: nitrogen 40-81%, carbon dioxide 19-60%, and residual oxygen content 1.8% or less. In this state, the sealing state of the barn 10 is maintained at 1~ The effect of prevention and control can be achieved within 24 hours, and then the grain and the grain powder can be injected into the barn 10 after the gas (material) is opened, so that the control method of the invention can be implemented on the barn 10 as long as there is a feed gap. The quality of the barn 10 is ensured, and the grain and flour that are shipped from the barn 10 are non-toxic and highly safe. In the above embodiment, the lower the residual oxygen amount, the more easily the worms in the barn 10 are suffocated, and the ratio of the air in the storage space 11 after the combination of nitrogen and carbon dioxide is 100%. The oxygen residual after mixing with nitrogen and carbon dioxide is below 1.8%. For example, when the nitrogen concentration is 72%, the carbon dioxide concentration is 28%, and the residual oxygen is 1.8% or less after mixing with nitrogen and carbon dioxide. In this state, it has a good effect on biological control.
