“Low Temperature Large Air Volume” Drying Technology

“Low Temperature Large Air Volume” Drying Technology is researched by ZJN technical R&D Team, is an important technical invention based on the principle of water evaporation. It has been successfully applied in the ZJN patented product “Rotary Rake Three-stage Multi-loops” high-humidity and high-viscosity material drying equipment, and obtained excellent drying effect.

As the name suggested,“Low Temperature Large Air Volume” is a drying process that when the input temperature is low, to increase the hot air volume appropriately within the set range, thus reach to the drying effects.

In the specific drying practice, the "low temperature large air volume" drying process has many obvious technical advantages:

Firstly, the most significant effect is energy saving, because the hot air temperature is reduced, the heat used in the drying process is relatively reduced, thus the energy demand is reduced.

Secondly, this drying technology can effectively suppress the generation of harmful dioxin gases in the drying process, especially when drying sludge materials, lowering the temperature means reducing the chance of dioxin formation (It does not produce dioxins under 300 degrees.) Thus it also facilitates the treatment of later exhaust emissions.

Thirdly, it can ensure the stability of materials’ physical and chemical properties, especially when the feed and residues materials are dried. After drying, the materials won’t be burnt, and the color is bright, and the trace elements and nutrients also won’t be damaged.

At last, the“Low Temperature Large Air Volume”drying technology can suppress the corrosion of harmful gases to the equipment, thus effectively extending the service life of the equipment. At the same time, the "low temperature large air volume" drying process also provides the necessary conditions for the implementation of the drying process of "utilizing boiler flue gas waste heat" by ZJN.
