Conveyor dishwashing machine, and method for operating a conveyor dishwashing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor dishwashing machines face reduced capacity when treatment parameters require longer dwell times for heavily soiled items, leading to lower washing performance during peak times due to slower transport speeds and longer treatment programs.
Innovation Solution
The machine is configured with at least two parallel washing planes within treatment zones, allowing for different treatment parameters, such as exposure time, mechanical washing action, and rinse composition, to be applied independently to each plane, enabling simultaneous treatment of items with varying soiling levels without reducing overall capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transport speed is reduced to increase dwell time for heavily soiled items, then the washing quality for heavily soiled items is improved, but the overall capacity of the dishwashing machine is reduced
Solution Approach 1:
The washing machine is divided into multiple washing planes (first washing plane and second washing plane) that operate independently. Each plane can have different transport speeds and treatment parameters, allowing heavily soiled items to receive extended treatment in one plane while less soiled items move faster through another plane, thus resolving the contradiction between washing quality and capacity
Solution Approach 2:
The invention adds a vertical dimension by stacking multiple washing planes above and below the horizontal midline of the machine. This three-dimensional arrangement allows parallel processing of different item types with different requirements, enabling the system to maintain high capacity while providing intensive treatment for heavily soiled items in specific planes
2Manufacturing precision
If the transport speed is reduced to allow longer treatment programs, then the washing performance for heavily soiled items is improved, but the throughput of the machine is reduced
Solution Approach 1:
Each washing plane can independently adjust its transport speed and treatment parameters dynamically. Heavily soiled items are routed to planes with slower transport speeds and longer dwell times for intensive treatment, while less soiled items are processed in planes with faster transport speeds, thus maintaining high throughput overall while achieving high washing performance for heavily soiled items
Solution Approach 2:
Different washing planes are configured with different local qualities - varying spray patterns, water temperatures, chemical dosing, and transport speeds - to match the specific requirements of different item types. This allows the system to optimize treatment for heavily soiled items in specific planes without compromising the efficiency of processing less soiled items in other planes

AI summary
A conveyor dishwashing machine (1) has at least one washing zone (7), and at least one final rinse zone (8) which is connected downstream (as viewed in the transport direction (T) of the wash items) of the at least one washing zone (7). The conveyor dishwashing machine (1) has a transport apparatus for transporting the wash items through the treatment zones (6, 7) of the conveyor dishwashing machine (1) so that the wash items are situated at least in regions in a washing plane (5) which runs horizontally. The washing plane (5) is configured as a main washing plane, and there is at least one additional washing plane (6) in at least one of the treatment zones (7, 8) of the conveyor dishwashing machine (1), in which additional washing plane (6) wash items can be treated at the same time as wash items in the main washing plane (5).
