01Convert output into conveyor speed
Assume 600 parts per hour, two parts per row and a row pitch of 0.20m in the direction of travel. The feed rate is 600 / 60 / 2 = 5 rows per minute. The required conveyor speed is 5 × 0.20 = 1.0m/min, approximately 3.28ft/min.
Pitch is measured from one row start to the next. A 0.15m-long part with a 0.05m gap gives a 0.20m pitch. This is ideal continuous loading; missed positions, changeovers and stops are not included.
02Apply the validated residence time
Heated travel length L = conveyor speed v × residence time t. If the product process requires 12 minutes in the heated path, the example needs 1.0 × 12 = 12m, approximately 39.4ft.
Clarify whether those 12 minutes include product heat-up and the required soak. “Hold for eight minutes after the product reaches temperature” does not mean total residence can be eight minutes. Chamber setpoint alone does not verify the product condition.
03Check the same relationship in either direction
| Known inputs | Calculation | Illustrative result |
|---|---|---|
| 1m/min and 12min | L = v × t | 12m heated travel |
| 12m and 15min | v = L / t | 0.8m/min |
| 12m and 1.5m/min | t = L / v | 8min |
04Allow for the rest of the line
Check loading, unloading, transitions, cooling, drive equipment and service space separately. State the time and temperature required in each zone. Usable loading width also needs a check against the actual arrangement and clearances.
Use the conveyor timing calculator to check the conversions. Send a loading sketch, product dimensions, output target, temperature profile and available floor plan with the inquiry. Heater power needs a separate heat balance.
