If it's only one or two bags, just sieve it with a finer sieve.

If the quantity is large, there is no good way, so we have to pull it to a larger flour mill for recycling. The flour mill has large-scale recycling equipment, which is easy to handle.

Some measures should be taken to prevent insects:

1, well ventilated

Flour has the function of breathing, so let the air circulate and let the flour have air.

2. Humidity drying

Flour will change its water content according to the temperature and humidity of the environment. The higher the humidity, the higher the water content of flour, which is easy to agglomerate. The lower the humidity, the lower the water content of flour. The ideal humidity is about 60%-70%.

3. Comfortable temperature

Storage temperature will affect the ripening time of flour. The higher the temperature, the faster the maturity. But the temperature will also shorten the shelf life of flour. The recommended ideal temperature for flour storage is 18℃-24℃.

4. Clean environment

A clean environment can reduce the breeding of pests and microorganisms, thus reducing the chance of flour pollution.

5, no odor

Flour is a substance that can absorb and store the odor in the air, so there should be no odor in the surrounding environment where flour is stored.

Step 6 get away from walls and floors

In order to have good ventilation, reduce moisture, reduce the pollution of insects and rats and the provisions of the law, this is necessary.

Plastic products should be used for stacking plates. If you use wood products, you should pay attention to avoid wood thorns and make them polluted.

7. First in first out

Ensure the stability of flour and reduce the artificial expiration of flour.

8, regular cleaning

Reduce the breeding of insects and rats, and then reduce the probability of flour pollution and packaging damage.
