Optimum temperature and humidity for grain storage

When the water content is low (below 12.5%) and the ambient temperature is low (below 15 ~ 20℃), the respiratory intensity is weak, but it can maintain the minimum life activities and is beneficial to storage.

During normal storage, the water content of grain is generally below 12%, which is a safe state and there will be no sudden temperature change. Once the moisture content of grain reaches more than 20% due to water condensation in the granary.

Because the grain is wet, the germs germinate, the metabolism is accelerated, and the respiratory heat is generated, so that the local grain temperature suddenly rises, which will inevitably lead to the "fever" and mildew of the grain, and may form a chain reaction, causing irreparable losses.

Almost all foods and drinks are very sensitive to temperature, humidity and light. Different foods and drinks have different degrees under the same temperature, humidity and light conditions. Therefore, different foods and drinks should be stored in different warehouses, and given different temperature, humidity and lighting conditions, so that foods and drinks are always in the best edible state.

Optimum storage temperature of different foods;

1, the best cold storage temperature of fresh fish is about -3 degrees Celsius. If it is about-18 degrees Celsius, it can keep fresh fish for half a year.

2. Meat can be stored at 2-5 degrees Celsius for one week.

3. Barreled beer and bottled beer should be stored at 0- 15 degrees Celsius, while bottled mature beer should be stored at about 10- 15 degrees Celsius.

4. The optimum temperature of fresh milk in cold storage is 1-6 degrees Celsius, which can inhibit the reproduction of bacteria and prevent deterioration.

5. Storing tea at -20℃ can keep its excellent quality for a long time and protect its vitamins from being destroyed.
