Why choose drying equipments to dry food instead of natural drying?

In the past, drying food to extend its storage period was a common way of storing food from a long time ago. In the past, people began to hang food on the beams or put it in dry and ventilated places for storage, but this way of preservation is too constrained and the production capacity is also very low. Since natural drying is far from being able to meet the long-term preservation of some perishable foods, we will use drying machinery and equipment to replace natural drying.

Why is drying equipment better than natural drying?

1. Natural drying takes longer time, but drying machine can dry the material faster. In the industrial sector, this will increase production.
2. Natural drying will be affected by weather and temperature, but the drying equipments can be used no matter what weather or temperature.
3. The new drying equipments we developed can retain more of the original nutrients of the food.
4. The dryer can better control the drying temperature and grasp the drying state of the food.
5. The output of the dryer is more hygienic, but natural drying will inevitably have dust, and even tiny organisms.
