Hood-Type Batch Dishwasher with Dual Treatment Zones for Peak Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial batch dishwashers face bottlenecks during peak times due to long cycle times required for heavily soiled washware, leading to reduced capacity and increased manual handling, while resources like energy, water, and chemicals are not optimized for efficiency.
Innovation Solution
A hood-type dishwasher with a treatment chamber divided into two zones, allowing independent treatment of washware based on soiling levels, where the main zone handles lightly soiled items efficiently and an auxiliary zone handles heavily soiled items with extended cycles, optimizing resource use and maintaining overall capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single treatment zone is used in the dishwasher, then the device complexity is reduced, but the productivity decreases during peak times due to bottlenecks with heavily soiled washware
Solution Approach 1:
The treatment chamber is divided into two independent treatment zones (first and second zones), each capable of operating separately to handle different types of washware. This segmentation allows parallel processing of lightly soiled and heavily soiled items, eliminating bottlenecks and increasing overall productivity without requiring a completely separate washing system for each zone.
2Reliability
If extended wash cycles are used for heavily soiled washware, then the cleaning quality improves, but the loss of time increases and reduces overall dishwasher capacity
Solution Approach 1:
By segmenting the treatment chamber into two independent zones, the system can run extended wash cycles for heavily soiled washware in the second treatment zone while simultaneously operating shorter cycles for lightly soiled items in the first treatment zone. This parallel operation eliminates the time loss associated with extended cycles, as the dishwasher maintains high capacity utilization throughout the extended duration.
3Use of energy by moving object
If recirculated wash liquid is used for washing, then the use of energy and resources is reduced, but the manufacturing precision of cleaning decreases for heavily soiled washware
Solution Approach 1:
The system segments the washing approach by using recirculated wash liquid in the first treatment zone for lightly soiled washware (energy-efficient) while using fresh heated water in the second treatment zone for heavily soiled washware (high cleaning effectiveness). This segmented approach maintains both energy efficiency and cleaning precision by matching the washing method to the soiling level of the washware being treated.
4Adaptability or versatility
If a single wash system is used for all washware, then the device complexity is minimized, but the adaptability decreases for handling different soiling levels efficiently
Solution Approach 1:
The wash system is segmented into two independent treatment zones with separate spray systems, allowing each zone to be optimized for different soiling levels. The first zone handles lightly soiled washware with standard parameters, while the second zone handles heavily soiled washware with extended cycles and fresh heated water, providing adaptability without requiring a completely separate system for each washing scenario.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables continuous operation during peak times by efficiently cleaning all washware without delaying lightly soiled items, while ensuring heavily soiled items receive adequate cleaning, thus optimizing resource usage and maintaining dishwasher capacity.
Implementation Method 1
a wash pump, a line system which is connected to the wash pump... The wash liquid contained in the wash tank can be conveyed from the wash pump to the wash nozzles via the line system
Implementation Method 2
sprayed onto the washware to be cleaned through the wash nozzles in the treatment chamber
Implementation Method 3
The treatment chamber generally has arranged beneath it a wash tank in which liquid from the treatment chamber can flow back due to the force of gravity
