Grafica Introduces Hybrid Dryer (Gas + Electric) for drying wide variety of textile inks

Grafica’s hybrid dryer is meant for drying jobs printed with wide range of inks on a variety of substrates.

Single touch screen display automatically diagnosis for safety & faults during operation supported by artificial intelligence system with error message display on screen with alarm.

It’s insulated with high density rock wool and double fabrication throughout to retain maximum heat inside the chamber while keeping the outside relatively cool.

Exceptionally imposing airflow management system is facilitated by a very powerful low noise blower that discharges air circulating uniformly around the entire heating chamber’s inner hood through strategically placed holes. Incoming airflow passes through heating system to the printed surface. Because air creates a vacuum-like behaviour at the side of the conveyor and re-circulated to the top again.

Powerful air re-circulation with air purification system effectively scrubs solvents/ water away from the ink surface, thereby allowing faster drying times while lowering temperature requirements for a superior processing.

Heated air is recycled, which in effect reduces power consumption considerably, the heating bank consisting of extremely effective heaters are not continuously engaged and drawing power in order to maintain temperature setting. Air circulation system maintains equal heat distribution all over the chambers. External variable airflow damper is provided to adjust exhausted air, according to solvent saturation during production, so that the drying system can always operate in its most efficient manner thus reduces power consumption.

To further improve efficient and energy conservation, a tool- free adjustable entry and exit stainless steel shields are provided to further prevent heat from spilling out to the production area. Exhaust fan below the electrical box is purposely intended to keep the electrical components cool and fully operational.

Single touch screen display with high quality thermocouple sensor, keeps precise temperature inside the chamber to ensure perfect control of drying.

The dryer’s inner chamber has a separate module from the heater to prevent escaping heat from spilling out into the production area.

High quality PTFE coated antistatic conveyor belt comes as standard, which is firmly driven by an AC geared motor with a frequency inverter for precise speed control—a handy feature at times when the belt is fully.

The rubberised conveyor drive roller is specifically cambered for superior belt tracking irrespective if the workload is off centred drying on the conveyor.

The dryer is completely portable in design for ease of mobility or it can be anchored to the floor with its own foundation bolts for a more permanent location.

Finally, to keep the dryer in optimum operation condition, a fine graded filter collects fine fibers and lint which prevents them from detrimentally sticking to the heaters themselves.
