Rack Conveyor Dishwashers

Rack Conveyor Dishwashers

Commercial rack conveyor dishwashers provide high-capacity warewashing for large kitchens, hotels, canteens, hospitals, schools, catering operations and other high-volume foodservice environments. Designed to process racks of crockery continuously through a washing tunnel, these machines can provide substantially greater throughput than conventional undercounter and passthrough dishwashers where large quantities of plates, cutlery and suitable catering equipment need to be cleaned during busy service periods.

Our range of rack conveyor dishwashers includes commercial machines with different rack capacities, configurations and levels of automation to suit demanding professional operations. Depending on the model, features can include pre-wash sections, multiple washing and rinsing stages, drying systems, heat recovery and water treatment options. The correct machine will depend on the volume of warewashing required, available installation space and the workflow of your kitchen.

Choosing a Commercial Rack Conveyor Dishwasher

Rack conveyor dishwashers are designed for businesses with significantly higher washing requirements than can usually be handled efficiently by an undercounter or passthrough dishwasher. Instead of loading and unloading individual wash cycles, racks are fed through the machine continuously, allowing large quantities of crockery and other suitable items to be processed during busy periods.

When choosing a rack conveyor dishwasher, consider the number of racks you need to process during peak service, the available floor space and the overall configuration of the washing area. Rack capacity, conveyor speed, number of washing stages, electrical requirements and water consumption can all vary considerably between models and should be compared alongside the expected workload.

Rack Conveyor Dishwasher Capacity and Throughput

The throughput of a rack conveyor dishwasher is normally expressed in racks per hour, although manufacturers may also provide an estimated number of plates or other items that can be processed. This provides a useful way to compare machines, but actual throughput will depend on the type of items being washed, how racks are loaded and the operating conditions of the machine.

For a high-volume kitchen, selecting sufficient capacity for the busiest periods is important. A machine that is too small can create a bottleneck during service, while choosing substantially more capacity than the business requires can result in unnecessary installation and operating costs. Consider both current requirements and likely future demand when comparing rack conveyor dishwashers.

Continuous Rack Conveyor Washing

The conveyor system allows loaded racks to move progressively through the different stages of the washing process. Depending on the machine, this can include pre-washing, main washing, rinsing and drying, with each section designed to perform a specific part of the cleaning process.

This continuous arrangement can help separate the loading and unloading sides of the warewashing operation, making it easier to establish a consistent flow of dirty and clean crockery. The overall layout should allow sufficient space for loading tables, unloading areas, racks and staff movement around the machine.

Pre-Wash, Rinse and Drying Systems

Rack conveyor dishwashers are available with different combinations of washing and rinsing stages. Some higher-capacity machines include dedicated pre-wash sections to help remove heavier food residues before the main washing process, while additional rinsing stages can form part of the machine's overall cleaning system.

Drying systems are also available on some rack conveyor models and can help reduce the amount of manual handling required after washing. Heat recovery and other energy-related features may also be available depending on the machine. Always check the manufacturer's specifications to confirm the exact configuration and performance of an individual model.

Water Treatment and Commercial Installation

Water quality is an important consideration when installing high-capacity commercial warewashing equipment. Depending on the hardness of the local water supply and the requirements of the machine, a water softener or other water treatment system may be recommended to help manage limescale and maintain washing performance.

Rack conveyor dishwashers can also have substantial electrical, water and drainage requirements. The installation area must provide suitable connections and sufficient space for the complete machine and associated equipment. Professional installation should follow the manufacturer's requirements, including any requirements relating to drainage, ventilation, extraction or steam management.

Planning a Rack Conveyor Dishwasher System

A rack conveyor dishwasher is normally installed as part of a wider commercial warewashing area rather than as a standalone appliance. Loading tables, sorting areas, roller conveyors, corner sections, drying units and unloading tables can be used with suitable machines to create a continuous workflow through the washing area.

The layout should allow dirty items to enter the washing process from one direction while clean items leave through the appropriate unloading area. Careful planning of the available space and movement of staff can help prevent clean and dirty crockery from crossing paths unnecessarily during busy kitchen operations.

Rack Conveyor vs Passthrough Dishwashers

Passthrough dishwashers provide a high-capacity solution for busy professional kitchens using a hood-type design and individual racks. Rack conveyor dishwashers take this concept further by continuously moving racks through a dedicated washing tunnel, making them more appropriate for operations with substantially higher and more consistent washing volumes.

If your business does not require continuous high-volume rack processing, a Passthrough Dishwasher may provide a more compact and appropriate solution. For smaller kitchens and businesses with lower washing requirements, our Undercounter Dishwashers provide a more space-efficient alternative.

Finding the Right Rack Conveyor Dishwasher

Before choosing a commercial rack conveyor dishwasher, consider the maximum number of racks your kitchen needs to process during busy periods and compare this with the capacity of the machines available. The overall dimensions are equally important, as larger conveyor systems can require considerable floor space and additional room for loading, unloading and associated equipment.

Check the rack dimensions, conveyor capacity, electrical supply, water consumption, drainage requirements and any water treatment or extraction requirements before purchase. It is also worth considering the likely future workload of the business, as replacing a high-capacity warewashing system can be a significant investment.
