Summary
Conveyor dishwashers are built for continuous, high-volume warewashing in schools, hospitals, universities, and federal facilities. When properly designed with utilities, workflow, and staffing in mind, they deliver unmatched throughput, sanitation reliability, and inspection performance.
WHAT IS A CONVEYOR DISHWASHER?
A conveyor commercial dishwasher is a continuous-feed rack-based dish machine where racks move automatically through wash, rinse, and sanitize zones. Unlike door-type units that operate in batches, conveyor systems are designed for non-stop production during peak meal periods.
They are commonly paired with:
- Tray return systems
- Scrap troughs or pulpers
- Pre-rinse conveyor sections
- Clean outfeed conveyors
- High-capacity drying and rack storage
BEST USE CASES FOR CONVEYOR DISHWASHERS
Conveyor dish machines are ideal for:
- Public school districts
- Colleges & universities
- Hospitals & healthcare systems
- VA medical centers
- Corporate campuses
- Commissaries & production kitchens
- Correctional facilities
They are typically excessive for:
- Small restaurants
- Bars & cafés
- Churches
- Low-volume catering
Those environments are better served by door-type or undercounter machines.
HEAT VS CHEMICAL IN CONVEYOR SYSTEMS
Conveyor machines can use either sanitizing method, but selection is heavily influenced by inspection risk and volume:
High-Temp (Heat) Conveyor
- Final rinse at 180°F
- Preferred in:
- Schools
- Hospitals
- VA & federal environments
- Simplest inspection verification
Requires:
- Booster heater
- Significant hot water recovery
- Strong electrical or gas service
Low-Temp (Chemical) Conveyor
- Lower water temperatures
Requires:
- Continuous chemical injection
- Strict ppm logging
- Test strip discipline
Lower utility demand, but higher inspection dependence on staff behavior.

TYPICAL CAPACITY & PERFORMANCE
Designed for 400–2,000+ meals per hour depending on configuration.
WORKFLOW & SYSTEM DESIGN REQUIREMENTS
A conveyor dishwasher is not a single piece of equipment—it is a system. Proper performance requires:
- Tray return conveyors or roller tables
- Scrap troughs, pulpers, or pre-scrape stations
- Dedicated high-pressure pre-rinse
- Continuous rack loading zone
- Clean outfeed conveyors
- Air-dry zones sized for peak output
- Rack carts & clean ware staging
- Separation of dirty vs clean traffic
Improper workflow is the #1 cause of bottlenecks, labor overruns, and inspection failures in conveyor dishrooms.

COMMON INSPECTION FAILURES WITH CONVEYOR DISHWASHERS
- Inconsistent final rinse temperature across zones
- Sanitizer ppm not logged or verified
- No air-drying space for output volume
- Food debris bypassing pre-scrape systems
- Drain backups under load
- Hood ventilation not matched to steam volume
- No daily temperature or ppm logs
- Cross-traffic between dirty and clean sides

PROS & CONS OF CONVEYOR DISHWASHERS
Pros
- Massive throughput
- Consistent wash quality
- Reduced labor per rack vs door-type
- Ideal for tray systems
- Strong inspection reliability (when designed correctly)
- Scales well with institutional growth
Cons
- Highest upfront equipment cost
- Highest utility demand
- Requires professional design & coordination
- Larger footprint
- More complex startup & commissioning
WHEN A CONVEYOR SYSTEM IS REQUIRED (NOT OPTIONAL)
A conveyor dishwasher is required—not optional—when:
- Trays are used for service
- You exceed 400+ meals per hour consistently
- Staff cannot keep up with door-type loading
- Drying racks back up during service
- Inspection logs show recurring temperature/ppm issues
- Meal service is concentrated into short peak windows
MANUFACTURERS COMMONLY USED FOR CONVEYOR DISHWASHERS
Well-known manufacturers in this category include:
- Meiko
- Champion
- Hobart
- Jackson
- Insinger
- CMA Dishmachines
Selection should be based on:
- Institutional service network coverage
