Start-up

Automatic feeding, boiler on
On the control cabinet, set chest feeding to automatic: elevator 1, the cleaner and elevator 2 start by themselves and follow the chest level, starting at low and stopping at high. About 35 minutes later, start the boiler.
- Boiler: press On/Off once, then Start/Stop; it fills with water and heats up by itself (see the boiler manual)
Steam on, cooking starts
When the boiler reaches 0.5–0.6 MPa, open the steam valves on the chest and cook for about 45 minutes. Watch for steam at the outlet of the transfer screw.
- Valve openings: lower edge of valves 1 to 3 at about mark 4, valve 4 at about mark 4.5
Pre-heater 1 on
At the same time, open pre-heater 1; its display should read about 120 °C.
Start the flaker
After about 45 minutes of cooking, start the flaker: start the two motors one after the other, the second once the first runs smoothly.
Pre-heat the transfer screw
Open the valve of pre-heater 2 to warm up the transfer screw; the display should read about 140–150 °C.
Close the rolls, start the discharge conveyor
After the flaker has run for about a minute, close the rolls: turn the red knob on the hydraulic unit clockwise and set the pressure to about 4 on the gauge. Then start the conveyor at the flaker outlet.
50 minutes of cooking
After 50 minutes of cooking, with steam coming out at the transfer screw outlet, production can start.
Start the screws
Start the transfer screw, then the chest screw, and check that the chest screw’s inverter reading is steady. Set the transfer screw to about 30 Hz to begin with.
Set the flake thickness
Check the flakes and raise the hydraulic pressure step by step to set the thickness, up to 8–9 on the gauge.
Steady running, full output
Once running steadily, speed up the transfer screw step by step, up to 50 Hz.
