How it works

Recipe-based drying with PID control of air flow and temperature

SUKI dries electronic components for TDK Croatia in Kutina. Wet components are placed into the machine in a basket, and the operator selects the drying parameters from a recipe matched to the component type.

The air flow and temperature are regulated by a PID controller according to the selected parameters, while PT100 probes continuously measure the temperature throughout the entire cycle. Overheat protection is provided by thermostats, and basket lock sensors check that the basket is locked before the cycle starts.

Control

Interface and control logic

Drying follows a recipe that defines the air flow and temperature, with continuous PT100 probe monitoring and overheat protection provided by thermostats.

Physical control station

  • Basket locking latch
  • Emergency stop
  • Overheat protection thermostats

Functionality

  • Selection of the drying recipe by component type
  • Real-time display of air flow and temperature
  • Signaling of drying cycle completion
Installed equipment and features

Technical details

PID control

The air flow and temperature are precisely regulated according to the parameters of the selected recipe.

PT100 probes

Continuous temperature measurement throughout the entire drying cycle.

Safety locking

Basket lock sensors check that the basket is locked before the machine allows the cycle to start.

Thermal protection

Thermostats protect the motors and heaters from overheating during longer drying cycles.
