Electric heating machine for reducing the damp of wet cement in a screed |
(57) The present invention relates to an electric heating machine to reduce the damp of
wet cement in a screed by means of heat exchange with a liquid.
Such electric machine comprises an inlet duct for the entrance of the liquid inside
the machine, and an outlet duct for the exit of the liquid from it. Such ducts are
communicating.
The electric machine comprises, in addition, heat exchange devices, in fluid communication
with the inlet duct and able to increase the temperature of the incoming liquid and
circulation devices, able to make the liquid travel from the inlet duct to the outlet
duct and vice versa through a circuit in thermal contact with the damp cement of the
screed.
In addition, the electric machine is portable and comprises attachment and release
mechanisms of the ducts, such as to enable the easy connection and detachment of the
machine from the circuit.
