What is the difference between a desiccant dryer and a hot air dryer?

In the industrial industry, dehumidification dryers have gradually replaced traditional hot air dryers. The reason is that the dehumidification dryer is superior to the hot air dryer in terms of performance and use. Of course, many people don't understand, what is the difference between a dehumidification dryer and a hot air dryer?

First, we need to understand the four elements of drying: temperature, air volume, time and dew point value.

Compared with ordinary hot air dryers, dehumidifying dryers first remove most of the moisture in the air, and then use air with little moisture content to circulate hot air to dry the materials (the dry air may reach the dew point). Minus tens of degrees Celsius), so that the dry air can more effectively remove moisture from the material under heating, which is especially effective for materials that are difficult to dry. It can dry the moisture-absorbing material more thoroughly. For an ordinary hot air dryer, it can only rely on heating to volatilize the water on the surface, and then blow it away with the wind. The moisture content of the final material can only be balanced with the moisture content of the air sucked in from the outside.

For materials with very low moisture content that need to be molded, ordinary hot air dryers cannot meet the requirements. At present, some reforms of the hot air recovery cycle connect the air outlet with the air inlet, and the water will always circulate inside, and there is no place for drainage, which is imperfect. However, Nigas dehumidification dryer has considered and effectively solved the above-mentioned problems. problem.
