If your facility processes several thousand dishes per day and your dishwashing staff are running three shifts just to keep up — you do not need more staff. You need a conveyor dishwasher.
Unlike ultrasonic or hood-type machines, a conveyor system allows dishes to be placed directly onto the belt without racking. They enter at one end and emerge washed and dried at the other. Throughput: approximately 1,000 pieces per hour. That is equivalent to four full-time dishwashers working an entire shift — accomplished by one machine in approximately 21 hours.
Three qualification criteria:
· Daily covers exceed 500: School canteens, corporate dining facilities, large-scale chain central kitchens.
· Meal service is concentrated within narrow time windows: Several thousand dishware items require processing within a 1-2 hour peak period.
· Hygiene compliance requirements are stringent: Hospital catering, airline meal services, high-speed rail food supply.
If two or more criteria apply to your operation, a conveyor system is the correct specification decision.
Type | Loading Method | Optimal For | Key Advantage | Target Application |
Pass-Through (Tunnel) | Dishes racked → pushed through → exit opposite end | Standard plates, bowls, cups | Dual-station capability doubles throughput (60→120→240 racks/hr) | Large canteens, standard dishware |
Flat-Bed | Dishes placed face-down directly on conveyor belt | Fast-food trays, cafeteria trays, irregular items | Eliminates racking labour; fan-shaped spray nozzles provide 360° coverage | Chain QSR, tray-based operations |
Slant-Rack | Dishes inserted at an angle into dedicated slots | Deep bowls, soup bowls, irregular vessels | Angled positioning prevents water pooling; superior rinse coverage | Noodle restaurants, soup-based cuisine |
Example: corporate canteen serving 3,000 covers per day.
Manual Washing | Conveyor System | |
Dishwashing staff | 4 persons (3 shifts) | 1-2 operators |
Monthly wages (¥3,500/person) | ¥14,000 | ¥3,500-7,000 |
Daily throughput | ~7,000 pieces | ~7,000 pieces (well within capacity) |
Monthly throughput | 210,000 pieces | 210,000 pieces (requires only 21 machine-hours) |
Annual labour cost | ¥168,000 | ¥42,000-84,000 |
Annual savings | — | ¥84,000-126,000 |
Equipment investment recovery period: 6-12 months. This calculation excludes reduced dishware breakage (manual handling causes higher attrition) and utility savings from the waterfall-style water recirculation system.
CHINENG conveyor dishwashers employ a modular architecture — configure wash, rinse, and drying modules to match your exact requirements.
Component | Specification | Function |
Wash Module | 55-65°C recirculated hot water, 4+2 fan-nozzle array | High-pressure spray removes food residue and grease |
Rinse Module | 85°C fresh hot water rinse | Thermal sanitisation; detergent residue removal |
Drying Module (optional) | 100°C+ forced hot air | Dishes exit dry, ready for immediate use |
Conveyor System | Food-grade plastic belt, corrosion-resistant, heat-tolerant | Direct dish placement; zero dishware breakage |
Safety Interlock | Auto-stop on door/panel opening | Operator protection |
Water Recirculation | Cascade-type inter-tank flow; single inlet, single drain | Approximately 30% water savings vs. conventional conveyor systems |
Construction | SUS304 stainless steel throughout; 2.0 mm frame | GB4806.7/9 food-contact compliant |
Daily Covers | Recommended Configuration | Machine Length |
300-500 | 1 wash + 1 rinse | 2.6-3.4 m |
500-1,000 | 2 wash + 1 rinse | 4.2-5.2 m |
1,000-2,000 | 2 wash + 1 rinse + drying | 5.2-5.9 m |
2,000+ | Pre-wash + 2 wash + rinse + dual drying | 5.8-6.2 m |
· Electrical: 380 V three-phase supply. Verify panel capacity.
· Water: Adequate inlet pressure. Hard water areas require a softening system.
· Drainage: Floor drain or trench with sufficient gradient.
· Clearance: Machine length + minimum 1.5 m operational space at both ends.
· Ventilation: Drying-equipped models require consideration of hot air exhaust.
· Daily: Clear conveyor belt of food debris. Inspect spray nozzles for blockages.
· Weekly: Clean filtration screens. Verify detergent and rinse-aid levels.
· Monthly: Inspect pump and heating element operation. Descale if indicated.
Q: What are the utility consumption figures?
CHINENG's cascade water recirculation delivers approximately 30% water savings versus conventional conveyor designs. A standard 5.2 m configuration draws approximately 30-40 kW at full load. At industrial electricity rates, operating cost is approximately ¥20-30 per hour.
Q: Is pre-soaking or pre-scraping required?
Standard post-meal dishware does not require pre-treatment. Scrape off bulk food waste and place directly onto the conveyor. Heavily soiled items with dried-on residue may benefit from brief pre-soaking.
Q: Can irregular-shaped items be washed?
Flat-bed and slant-rack configurations accommodate irregular dishware well. Pass-through configurations require racking and are optimised for standard-dimension items. Select the configuration based on your primary dishware type.
Q: What is the service protocol if the unit requires maintenance?
CHINENG provides a 12-month comprehensive warranty with lifetime maintenance support. The "104" service standard applies: 10-minute response acknowledgement, 4-hour on-site dispatch. The modular design allows individual module repair without affecting other sections.
A conveyor dishwasher represents the largest equipment investment in your kitchen — and the highest-return. Correct specification delivers six-figure annual labour savings. Incorrect specification wastes valuable floor space with inadequate performance.
