How to store rice so that it does not give birth to insects?

First of all, it is necessary to remove impurities from the rice. After the rice is harvested, it generally contains bran ash, barnyard grains and deflated grains, etc., these impurities have large water content and strong hygroscopicity, which makes the porosity of the grain pile smaller, the internal damp heat is easy to accumulate and is not easy to dissipate, and the bacteria and pests are easy to infect and multiply. Therefore, these impurities should be removed by sieving and other methods to reduce the impurity content to the following.

After the rice is removed, the precipitation should be dried immediately by drying, exhausting, drying and other methods to make it reach below the safe storage moisture. The safe storage moisture of rice varies slightly depending on the variety, and indica, japonica and waxy rice are generally % respectively. Poor thermal conductivity of rice accumulation, you can take advantage of the favorable opportunity when the temperature gradually decreases after the autumn coolness, open the doors and windows of the warehouse, the container mouth to ventilate and cool, and seal the gland, implement low-temperature and low-oxygen storage, and enhance the stability of storage, so that there will be no insects.

If the rice wants to be preserved without insects, then it is necessary to clean the rice and dry it, store it in a dry and ventilated place, and you can choose some anthelmintic drugs to put in it.

First of all, the impurities in the rice should be removed, then it should be dried to reduce the moisture content of the rice, and finally it should be stored at low temperature and low humidity.

To store the grains, you can put peppercorns, so that there are not easy bugs. You can wrap the peppercorns with gauze into several hangings, put them into the top, middle and bottom of the rice bowl respectively, and cover the lid tightly to prevent insects in the grains.

Kelp can also act as an insect repellent effect. Rice and kelp are mixed and packaged in a ratio of 10 to 1, and after 10 days, the kelp is taken out, dried and then put into a rice jar, so that it can be repeated several times to prevent rice insects. Dried kelp has strong hygroscopic properties and has an insecticidal and mold-inhibiting effect.

Paddy storage notes:

1. Store in an appropriate amount according to the season.

During the year, depending on the season, you can adjust the amount of rice at home. In general, the weather temperature is higher in summer and the air humidity.

Larger, rice is very susceptible to moisture and mold, and it is difficult to store, so it should be stored less. In autumn and winter, the temperature is low and the climate is dry, and the rice is not easy to be affected by the environment, and its edible quality can be stored in moderation.

2. Timely ventilation, moisture-proof and heat insulation.

In summer, the preservation of rice should pay attention to moisture-proof and heat insulation, and store it in a cool, dry and easily ventilated place as much as possible. Specifically, it is necessary to pay attention to moisture-proof and should not be mixed; Pay attention to heat insulation and keep away from heat sources; Pay attention to dry in the shade and avoid exposure to the sun.

3. Natural hypoxia, scientific insect control.

During the season of high temperature and humidity, there are many historical experiences in preventing rice insects. For example, mix a few heads of dried garlic in a rice bag (garlic food); Or take peppercorns or fennel.

Wrap it in several gauze bags, put it in a rice bag and seal it.

The main reason for this problem is that the aged rice has a slight dampness due to the longevity of the rice. The eggs carried in the grains begin to hatch, first a small number of small moths, if not treated, small hard-shelled insects will appear one by one rice weevils (commonly known as cattle If the number of dry rice is not particularly large, we can also put the dried rice in the refrigerator to freeze, so that the insects in the dry rice can be directly frozen to death, and then they can be easily picked out from the rice.

The kiln lime block is wrapped in cloth at the ratio of 3% to 5%, and put it at the bottom of the grain storage container or directly put it at the bottom with a palm block, cloth block, paper block septum, and then put the grain for sealing. By drying and absorbing moisture, the grain is preserved by sealing and drying, and the exposure is to act on the insect body with solar radiation heat, destroying the insect tissue and life function, and killing the pest. At the same time, exposure also has the effect of moisture and mildew.

Wheat, corn, peas, broad beans and other food pests can use this method.

The rice harvested early is usually milled and sold as new rice after being dried for a few days, and is rarely stockpiled. Because every year, the new rice that comes on the market early can be sold at a good price. Rice insect control is a science.

Especially in the next year, it is difficult to prevent insects. There are many ways to control insects in our hometown. One is to go to the mountains to pick three to five catties of mountain pepper (also known as mountain pulp) to dry.

I am also a rural person, my rice will also be regular, insects: white moths, acorns, research the reason is that the current rural people, the container for putting grain, are iron silos, plus underground, although there is a cement underground, but the iron sheet itself is easy to absorb moisture, the agent used to kill the pests of stored grain is strictly selected, must have two important conditions: one is the chemical properties are relatively stable, not easy to burn and burn; Second, it can kill a variety of pests, and there is no residual poison or minimal residual toxicity.

Farmers collect paddy, and the methods of the predecessors are adapted to local conditions, and local materials can be borrowed. After the former farmers retrieved the rice from the field, it was turned over and exposed to the sun in the sun through a spacious barning field.

If there is not much food, it can be sealed in the refrigerator and frozen for about 24 hours, when there is more food, we can not only clean pests by basking in the sun, but also prevent it in advance, keep the food storage space ventilated, and put things with a strong smell into the food.

The stored rice must be dried thoroughly, the warehouse must be rainproof and ventilated, regularly check whether there are signs of insects, or the temperature of the stored rice generally can not exceed 20, the temperature is too high will cause the rice to deteriorate, too low will be the rice damp and insects.

Rice preservation method:

The principle of storing rice is "dry, low-temperature, and airtight".

1. Control the moisture of rice.

Strictly control the moisture of the stored rice to make it meet the safe moisture standard, and the safe moisture standard of rice changes with the type of grain, season and climatic conditions.

2. Remove rice impurities.

Before storage, air lifting, sieving or mechanical impurity removal are carried out to reduce the impurity content to a minimum, so as to improve the storage stability of rice. Reduce the impurity content in rice to the following and improve the storage stability of rice.

3. Graded storage of paddy.

Rice should be stored in different grades, that is, it should be stacked separately according to variety, good order, new age, dry and wet, and insects and insects.

4. Rice ventilation and cooling.

After the rice is put into storage, it should be ventilated and cooled in time to prevent condensation. In three phases of September and October, November and December, and January and February, intermittent mechanical ventilation can reduce the grain temperature from 33 to 35 degrees Celsius to below 10 degrees Celsius in stages.

5. Control rice pests.

After the rice is put into storage, effective measures should be taken in time to comprehensively control pests. Usually the use of protective agents or fumigants for prevention and control.

6. Closed rice grain pile.

In late winter and early spring, when the grain temperature is the lowest before the temperature rises, Chenglin Grain adopts effective methods to cover the grain surface and store it in a closed storage to keep the rice pile in a low temperature (15 degrees Celsius) or quasi-low temperature (20 degrees Celsius) state. The commonly used methods of sealing grain piles are: the whole warehouse is sealed, the top of the plastic film cover is sealed, and a small amount of grain can also be sealed with grass ash or dry river sand cover.

Insect rice treatment method:

1. Put it in the refrigerator and freeze for 24 hours. If the insects are not serious, you can put the rice in the freezer with the bag and take it out after 24 hours, at this time the insects are frozen to death and turn red and black, which is easy to pick up, and will not affect the original taste of the rice.

2. Place in a cool place to dry. After the rice is insected, people often like to expose the rice to the sun, which not only fails to achieve the purpose of killing the rice worms, but will be counterproductive, because after two or three days, the rice worms in the rice will increase unabated, and the exposed rice will also lose moisture and affect the taste.

The correct way to do this is to put the rice in a cool and ventilated place, let the insects crawl out slowly, and then sieve again.

The insect-infested rice can be placed in an airtight container, and a piece of grain insect net fumigation can be added for every 1 cubic meter of rice. The main ingredient of Grain Insect Net is aluminum phosphide, which will release highly toxic phosphine gas when exposed to water, so be careful when using it.

Many farmers will grow rice for food, and after the harvest every year, they will save it for daily use. So how to preserve rice so that it will not give birth to insects?

1. How to save it. If the rice is free of insects, it should be dried through a sieve and stored in a dry and low temperature place. Clean the inside and outside of the granary first and then place it for a few days until the air is dry, the ground should be covered with moisture-proof wooden boards and straw mats, and the rice that has been screened and dried for 3 days is placed in a dry and cool place, and the paper bags mixed with plant ash, coal ash, pepper and other moisture-proof and insect-proof paper bags can be spread on the rice.

2. Insect treatment. Rice insects can be sieved or smoked with pesticides. If there are not many insects in the rice, you can put dried stinky leaves in the rice, which can prevent sorghum aphids and malt worms, and wait for a night, sieve the rice to remove the remaining insects, or smoke it according to the national standard of pesticides.

3. Mold treatment. Rice that is not seriously moldy can be turned and exposed to the sun in the sun. Remove the rice that has been seriously moldy, and expose the remaining rice to the sun on a sunny day, spread the rice evenly on the ground, with a thickness of about 4 cm, and turn the rice twice every half an hour, which needs to be dried for about 6 hours.

That's all there is to you about how to preserve rice so that it doesn't get insects.

The main purpose of rice storage is to prevent moisture, mildew and insect damage. The easiest way is to wash and dry the granary and hoard, and then put 20 to 30 cm of moisture-insulating wooden planks away from the wall. Then the sun-dried rice is loaded, the surface is covered with paper, and an appropriate amount of mixed plant ash, sugar ash, lime and coal ash is placed on the paper, which can be moisture-proof and insect-proof.
