ABSTRACT:
A drying and freezing method without cooling medium comprises the steps of removing moisture, separating cold air from hot air and mixing the cold air with the hot air. Under the condition of no cooling medium, the above-mentioned steps separate the moisture from the compressed air, separate the cold air from the hot air and mix the cold air with the hot air. The system using the drying and freezing method without cooling medium comprises at least one air dryer having an air-moisture separation chamber for separating air from moisture and at least one separator having a separation chamber for separating cold air from hot air. The separator is connected to a pipeline to mix the cold air with the hot air.
