Wet sludge is introduced into the drier and homogenously deposited on the drying belt by means of an extruder that facilitates the flow of air and the transfer of heat. The system admits any heat source that allows it to operate with a hot water circuit (75/90ºC).
The belt carries the sludge through a closed tunnel, where air is circulated at 65/80ºC, condensing the humid air in such a way that water is only extracted to the exterior. The belts cover the entire tunnel to prevent the generation of dust and possible obstructions.
Once dry, the resulting product is easy to transport, having lost as much as 70% of its volume, guaranteeing a dry content rate of 90%.
Its low-temperature operation maximises the use of residual energy, such as exhaust gases from cogeneration or cooling water from engines.
An experienced and multi-disciplinary team covers all the phases of the project, from design and manufacturing through to assembly and maintenance. The driers are fully assembled and tested in the factory to make the process as easy as possible for the customer.
Outside the scope of application of the ATEX Directive (zero risk of explosion or fire).
It does not generate dust.
The drier can be adapted to the energy needs of any customer. The 75/90ºC hot water used in the process can be obtained from various energy sources, such as natural gas boilers, cogeneration engines and heat pump technologies.
Reduction of environmental impact. It limits greenhouse gas emissions. Its cold source and closed air system inside the tunnel reduce both the size of the deodorisation system and the emission of odours.
Easy to use
Quick and fully automated commissioning process.
Partial maintenance without shutdowns.
Easy access to all the equipment.
Possibility of maintenance contracts for up to 15 years.
Extremely safe and efficient technology.
