8% Moisture target hit
3 Mole runs to balance
½ day To production restart

HEB’s hearth-plate oven was running uneven: control side and non-control side at visibly different temperatures, with the damper run open as a workaround. Hank Pickering and Morgan Henry were on site for two days: baseline mole runs across three zones, burner balance, ignitor and flex-hose and gas-line repairs, and coloraider re-positioning. By the afternoon of day one, production was back up. The result: full bake throughout, ~8% moisture, minimal color variance.

The challenge

HEB's Baker Thermal DFG hearth-plate oven was baking unevenly, with the control side and non-control side at visibly different temperatures and the damper run open as a workaround. Uneven bake, efficiency complaint.

The work

Baseline and balancing via mole runs across three zones (Control Side, Center, Non-Control Side), followed by ignitor, flex-hose, and gas-line repairs and coloraider re-positioning.

The outcome

Full bake throughout, ~8% moisture, minimal color variance. Production restarted by the afternoon of day one.
