“Conveyor dryers, rotary dryers, dryers with transport chains, and transport carts.”
In continuous dryers the material travels through the dryers made up of several zones; in each zone several different physical and chemical processes take place. The dryers differ with regard to the manner the products are transported through the dryer: conveyor belt, transport chains, transport carts or rotary pumps.
“Achieving even material dryness through strict parameter control in the dryer.”
As the goal in the initial zones of the dryer is to raise the product temperature, a high level of moisture of the air circulating around the product is necessary. This increases the diffusion in the product interior onto the surface. In the further zones, the level of moisture in the circulating air increases – as a result the diffusion from the product surface into the air increases as well.
Through proper moisture and temperature parameter control we can achieve the even dryness of materials throughout and prevent the surface of materials from overbaking. Where the goal is the binder polymerization of products, the temperature at which the binder polymerizes and the product takes shape also changes.
To achieve the evenness of products, a powerful, forceful mixing of particles in the atmosphere takes place, with the help of an appropriately powerful air flow vent.
“Saving on the invested energy.”
With continuous dryers smaller energy investments are required per material unit as the dryers do not need to be cooled down and reheated when a new batch is introduced. As the products travel against the current, against the air flow, the products of lower temperature can make use of the higher temperatures in the dryer.
“Technically superior dryer equipment.”
To achieve the required parameters the dryer is equipped with:
- the needed number of gas burners
- temperature and moisture monitors in different zones
- with a moisture outlet system
- built-in recuperative burner to maximize the use of the energy source
- Scada steering system and user panel.
