How to Zone Functional Areas in a Central Kitchen

Brands like KFC and McDonald’s deliver standardized taste via central kitchens. How should functional zones be divided when building one? CHINENG explains.

Central kitchen functional zones

1. Cooking zone: where ingredients and seasonings become finished dishes—layout must support smooth cook flow.

2. Wash zone: sinks and detergents for ingredient washing and dish washing.

3. Hot kitchen: cut, hold, and cook semi-finished items—sized for high volume and complex steps.

4. Produce rough prep: wash and primary cut of fruit/vegetables, with chilled rooms for storage and turnover.

5. Meat rough prep: wash and primary cut of meat with chill/freeze rooms.

6. Bakery/staple room: cook noodles and steamed goods with tables, sinks, and refrigerators.

7. Packing room: packaging line plus worktables for finish and case packing.

8. Ware storage: orderly, dust- and pest-protected tool and dish storage.

9. Wash/sanitize room: crate and ware cleaning with scrap stations, large sinks, crate washers, and racks.

10. Storage: easy access without blocking other zones.

11. Waste holding: waste chill rooms, processors, and sterilizing lamps.

Summary: store, prep, wash, cook, pack, and clean—equip each zone to need. Contact CHINENG for efficient low-cost commissary design.
