AI Technical Summary
The drying equipment in existing gravure printing presses consumes a lot of energy and needs to be improved to reduce energy consumption.
Heat exchange is achieved through a ventilation duct assembly within the enclosure. The design incorporates inlet, outlet, and return air ducts, utilizing thin metal plates within the exchange core for heat recovery and heating. Combined with a condenser dehumidifier and heater, this process converts hot, humid air into cool, dry air, reducing the temperature of high-temperature fluids and increasing the temperature of low-temperature fluids, thus achieving energy savings.
Energy savings were achieved in the ink drying process of gravure printing machines, reducing energy consumption, and further energy savings were achieved through the recovery of condensate.
