Dryer Operation
Set the Heat:
With the dryer plugged in, rotate the Variable Control Timer to the desired setting. Often times, it is
best to run the dryer on HI and adjust your belt speed and heater height to achieve a proper cure.
Curing Plastisol with infrared:
Plastisol ink can fully cure in approximately 20-30* seconds. Most inks must achieve 320°-330 F (160°-165°C) throughout to
cure and fuse to the garment. The thicker the ink the hotter the top skin has to be in order to be cured completely to the garment.
Discharge or water based:
(A powered exhaust is recommended)
Water based products require more time than plastisol to cure due to the fact that the water/moisture must be evaporated before
the ink can cure. We have seen cure times from 50 to 90* seconds to achieve a full cure or discharge and not damage the gar-
ment. Please note as the time is increased the temperature must be decreased to protect the garment from scorching.
*Actual cure times can vary depending on conditions such as garment moisture and color, ink color, ink thickness, and
environmental conditions. All three variables should be used to maximize production while insuring a proper cure.
Turn on the Heat
:
Turn the Variable Heat Control dial on HI for 10-15 minutes to allow the dryer to warm up.
Set the Belt Speed
:
Rotate the Belt Speed Control Knob clockwise to increase speed and counter-clockwise to
decrease it. For Plastisol inks, a good starting point is 20-25 seconds in the chamber. The
dial numbers are for reference only. They do not represent seconds in the chamber.
Set the Heater Height
:
Set the desired heater height for your job. On each side of the heating chamber, there is a knob to
raise and lower the heater. It is recommended to run the heater height at about 2” - 3” above the
garment. The heater can be run at an angle for curing non-flat sub-straights such as hats.
Turn on Conveyor
:
Set belt speed with the Belt Speed Control on the conveyor, near the motor.
Check belt path:
Remove any objects from the conveyor and belt.
Plug in Dryer:
Be sure the breaker and dryer controls are switched off. Plug the dryer into a properly
rated outlet and turn the breaker on.
Startup Procedure
Operation Tips
While machine is in operation, it is necessary to have the belt moving while the heater is above 300°F (149°C).
Allow approximately 15 minutes for dryer to reach Full temperature.
If no garments are being run through the dryer for more than 10 minutes, it is recommended to lower the dryer
heat control to “4” or lower. It will take approximately 10 minutes to return to operating temperature.
Periodically check ink temperature at the exit of the dryer. It is recommended that you check the temperature of
the ink towards the outside of the printed image.
When checking temperature with a laser gun, shoot the ink while it is still under the heating elements.
Turn off Breaker
:
Turn off the breaker controlling the dryers at the end of each shift and unplug them from
their outlets.
Turn off Conveyor
:
Once the dryer cools down to 300°F (149
°
C)
or lower, turn the Belt Speed down to the off
position. Skip this step if leaving the conveyor belt speed set for the following shift.
Turn off Heat:
Turn the Heat Control off. Allow the heaters to cool for 10-15 minutes before shutting the
conveyor off. Belt damage may result from stopping the conveyor with hot elements.
