The advantage of pulse combustion drying

The advantage of pulse combustion drying
     For the analysis of the information publicly reported results, pulse combustion drying improves the thermal mass (moisture) transmission rate, reduces the drying time of the material, increasing the production capacity of industrial dryers. Moreover, the pulse combustion dryer thermal efficiency, can be effectively dried low or high viscosity liquid or paste materials. As the material in the drying chamber residence time is rather short, compared to other methods of combustion gas temperature drop value is low enough to produce oxides of nitrogen, the emissions of nitrogen oxides is very low. Such as the use of sulfur-free fuels such as natural gas, can be used for drying food and biological products. With conventional drying techniques (continuous drying) compared to pulse combustion drying has the following characteristics:
     1. Improve drying speed 2-3 times;
     2. reduce the unit air consumption 30% -40%;
     3 to avoid the feature quantity at various locations within the dryer (temperature, density, moisture content) of the uneven distribution of product quality;
     4 Easy handling sticky material caking or agglomeration (without mechanical stirring and crushing);
     5 dispersing liquids, slurries and suspensions (not rotary atomizer, or pressure nozzle);
     6 during operation, the gas and the product temperature is low;
     7 less air into the atmosphere;
     8 The system does not require use of blowers.
