The principle of fruit and vegetable dryer

After the fruits and vegetables to be processed are processed, they are put into a closed container, and then the materials to be processed are heated inside the container by introducing high-temperature airflow generated by the heating device. During this process, moisture will continue to be emitted from the surface of the material, and the emitted moisture will rise to the outside of the upper chamber with the air flow.
The bypass airflow is then cooled using a cooling device. When the cooling device cools the bypass airflow, the moisture will be atomized and then flow back into the room in the form of mist. During this process, a large amount of moisture is constantly emitted from the food, atomized, and returned to the room; in addition, as time goes by, the material will gradually dry out. When all the water is completely extracted, dry fruit and vegetable products will be obtained.
