Heavy-Duty Commercial Long Dragon Automatic Dishwasher GB-X11H1(Y)

The Changlong dishwasher model GB-X11H1(Y) represents a high-capacity, continuous-feed commercial warewashing line designed specifically for large-scale institutional dining halls, commercial central kitchens, and flight catering operations. Featuring a double main wash, double rinse, and double drying configuration, this industrial flight dishwasher processes 2,000 to 3,000 items per hour (2000-3000H). Driven by an advanced computer board control system, the machine incorporates a front-end linked conveyor residue removal system alongside a high-pressure hot air circulation spray drying module. Built with food-grade stainless steel verified by national testing institutions, the GB-X11H1(Y) minimizes labor costs, reduces detergent and utility consumption, and ensures strict hygiene compliance across high-volume foodservice operations.

Technical Specifications & Certified Parameters

To assist facility planners, mechanical engineers, and procurement teams with layout and utility integration, the official technical parameters for the GB-X11H1(Y) commercial dishwasher are detailed below:

Precision Spray Engineering & Hydraulic Performance

Advanced Melt-Drilling & Hot-Melt Spray Arm Technology

Maintaining stable water pressure and consistent chemical distribution across prolonged operating cycles is essential for commercial warewashing equipment.

• Melt-Drilling and Melt-Tapping Construction: The nozzles on the main wash spray arms are manufactured using specialized melt-drilling and melt-tapping technology. By forming nozzles directly from the metal wall, this process eliminates weak joint seams, solving traditional operational problems such as internal sealing failures, pressure leakage, and nozzle clogging.

• High-Frequency Hot-Melt Joint Assembly: Structural pipe connections utilize high-frequency hot-melt technology. This process prevents water leaks and provides a smooth exterior surface that prevents grease and organic residue accumulation along the spray pipe welding.

• National-Certified Metallurgy: All internal spray arms are built using food-grade stainless steel material that has successfully passed testing by a national-level testing institution, ensuring complete resistance against harsh commercial detergents and thermal stress.

• Quick-Plug and Quick-Release Maintenance: To simplify shift cleanup, the spray arms feature a quick-plug and quick-release design. Kitchen staff can remove, inspect, flush, and reinstall the wash arms in seconds without tools.

Omnidirectional 360 Degree Cross-Spraying Hydraulics

• Up and Down Cross-Spraying Alignment: The internal washing chambers utilize a synchronized up and down cross-spraying arrangement. Fluid dynamic tests determined the optimal water outlet angle for maximum mechanical impact.

• Complete Blind-Spot Elimination: This multi-angle fluid layout provides continuous coverage across all dish surfaces, delivering 360 degreeall-round and no dead-angle washing for flat trays, deep bowls, and food containers.

Front-End Pre-Cleaning & Continuous Conveyance

Linked Conveyor Residue Separation

Manual pre-rinsing increases labor costs and slows down dishwashing throughput. The GB-X11H1(Y) automates initial food residue handling before dishes enter the main wash zone.

• Automated Residue Removal: A linked conveyor system lifts and removes residue from the front-end tableware before entering the cleaning equipment. By capturing solid debris early, the system maintains wash water clarity and reduces overall detergent consumption.

• Synchronized Continuous Feed: The conveyor transfers items smoothly into the double main wash chambers, maintaining line speed while protecting ceramic and metal tableware against chipping or tipping.

Dual-Stage Hot Air Spray Drying & Energy Efficiency

High-Pressure Hot Air Circulation Drying

In high-volume catering and cafeteria environments, fast tableware turnaround is critical to maintaining smooth operational flow.

• High-Pressure Hot Air Circulation Spray Drying System: The unit incorporates a unique high-pressure hot air circulation spray drying system within its double drying zone. Hot air is continuously recirculated over washed items, accelerating moisture evaporation while maintaining low consumption and high efficiency.

• Instant Tableware Reuse: Featuring a built-in drying function, dishes can be reused immediately after washing, eliminating the need to wait for air drying or allocate floor space to drying racks.

Intelligent Automation, System Control & Operator Safety

Automated Computer Board Diagnostics

Operating commercial kitchen equipment should be straightforward for line workers across rotating shifts.

• Computer Board Control System: Managed by an intuitive computer board control system, operators simply press to start the machine. The washer automatically manages water filling, tank balancing, and multi-stage element heating. Water intake and heating are completed with one key, eliminating cumbersome operations.

• 20 Fault Code Logic: The main board constantly monitors component performance. Featuring 20 fault codes, the diagnostic system isolates operational variances quickly, ensuring worry-free after-sales service.

• 19 Functions Diagnostic Display: An external interface panel features a 19 functions and fault code display readout that analyzes the cause of any fault to simplify ongoing control system maintenance.

Resource Management & Safety Systems

• Humanized Utility Efficiency: Incorporating an automated humanized design, the system manages automatic water intake and intelligent temperature control, delivering highly efficient water, electricity, and detergent saving performance during extended operating shifts.

• Damped Lift-Up Access Door: For easy cleaning of the interior, the main washing section uses a lift-up door with a damping structure that can stop at any position. This counterbalanced door stays securely in place during daily maintenance.

• Conveyor End Jam-Proof Safety: To protect tableware from crushing or backing up at the discharge end, a jam-proof system is installed at the end of the conveyor belt. The conveyor belt automatically stops if the dishes are not collected in time by kitchen porters.

Commercial Applications, Customization & Delivery

With a throughput capacity of 2,000 to 3,000 items per hour (2000-3000H) and multi-fuel adaptability (Electric heating, Steam heating, or Gas heating), the GB-X11H1(Y) supports a wide range of commercial operations:
