Direct Answer / Key Takeaway: Compare a conveyor with a manual tray line using the same menu, dispatch window and staffing record. Identify which work actually disappears and which simply moves.
A conveyor is a worthwhile investment when it removes a demonstrated restriction in meal assembly. It is a poor remedy for a problem elsewhere, such as late food replenishment, missing menu information or an insufficient number of dispatch carts. Compare the present process with a proposed process before putting a labour-saving figure into the business case.
Map what the manual line does today
Observe a representative meal wave from component staging to release of the last completed cart. Record the people involved and the time spent presenting trays, carrying them between positions, portioning, checking, replenishing and dispatching. Include people who help briefly from another department. Those visits are part of the work even when they do not appear on the tray-line roster.
Count completed, correct meals against the actual dispatch deadline. Keep late or reworked trays visible. The baseline should describe the process that staff can sustain, not the best few minutes observed during an unusually quiet menu. This places the comparison within the wider central kitchen operating model.
Identify the mechanism behind each claimed saving
For every task the proposal says will disappear, ask what replaces it. A moving belt may remove repeated tray carrying while leaving food replenishment and finished-cart handling unchanged. A new line might also introduce belt cleaning, setup, inspection or a different replenishment route. List those changes explicitly.
| Proposed benefit | Evidence needed |
|---|---|
| Fewer tray transfers | Observed transfer actions before and after, including any new end-of-line lift |
| Better station balance | Completed-tray timing and queues at each staffed position |
| Reduced staffing demand | A demonstrated roster for the same menu, checks and dispatch workload |
| More dependable dispatch | Results over representative waves, including normal replenishment and cart exchanges |
Do not convert every minute saved into a cash saving. Explain whether the change removes paid hours, avoids overtime, releases staff for another required task or simply creates spare time inside the same shift. These outcomes have different financial meanings.
Test the alternative before committing the room
Use the proposed tray arrangement and actual menu components in a demonstration or a carefully planned mock-up. Keep the comparison conditions consistent. If one process is supplied by a dedicated replenishment assistant and the other is not, the resulting staffing difference does not belong entirely to the conveyor.
Include setup and cleaning time in the daily comparison, particularly when the line runs for short meal waves. Consider the effect of a stop: where trays wait, how staff resume checks and whether there is a workable fallback process. A capacity improvement that cannot tolerate an ordinary interruption may not address the operator's real requirement.
Keep the purchase decision conditional on the result
Separate equipment price, installation changes, training, additional accessories and continuing service costs. Use supplier quotations and the site's own labour rates for financial calculations. A hypothetical annual saving should be labelled as an assumption until the underlying work changes have been demonstrated.
The accepted capacity and service-window assessment should accompany the recommendation. Purchase when the proposed arrangement demonstrably improves the required workload at an acceptable total cost. If the main restriction remains food availability or dispatch handling, address that restriction before expecting a moving tray surface to solve it.
