The birth of the industrial sublimation dryer

Since ancient times, in the high mountains of South America, the Incas in Peru were able to freeze meat and other foods. Under sunlight and low pressure, stored food tends to freeze and dry out.

All types of food are stored in military backpacks during operations. Later, in 1533, warehouses to preserve vegetables were also born.

By 1906, two French physicists Bordas and Darsonval researched and created a steam condenser by mixing acetone into snow during the drying process. After that, this method continued to be perfected to serve the US-Japan war.

By 1942 and 1943, the equipment was gradually perfected with greater capacity and introduced into the high-end preservation and processing industry. Currently, dryers with this technology are often applied to materials that need to be dried with high economic value.
