The dry heat source of the rotogravure printing machine

Since the ink layer of the rotogravure printing machine is thicker than the offset printing, it is necessary to use a drying system to rapidly evaporate and dry the ink solvent on the printed matter so that the ink is fixed on the substrate. Each color should be dried and the ink drying speed is matched to the printing speed.
Rotogravure printing machine drying method is usually hot air drying, the drying device by the heating equipment, ventilation equipment and exhaust port, etc. constitute a hot air drying room, printing from the hot air drying room through the drying. After adjusting the size of the air to control the drying speed. Selection of this boring equipment, sheet deformation is small, is conducive to ensuring the quality of printed materials. The sheets are usually cooled by hot air and should also be cooled by a cooling roll.

ROTOGRAVURE PRINTING MACHINE

Now rotogravure printing machine drying heat mainly has the following options:
1.Through the electric heating tube drying process;
2.Through the high temperature steam drying process;
3.Through the coal-fired boiler drying process;
4.Through the burning of diesel drying process;
5.Use the Covea hot air dryer as a heat source for drying.
