Mobile Spray Apparatus Segmentation for Baking Release Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional airless systems for applying release agents in the baking industry face issues such as short optimum spraying time, residue accumulation, contamination from compressor air, and the weight and return requirements of kegs, which limit mobility and efficiency.
Innovation Solution
A mobile fluid spray apparatus with a wheeled housing, a pressurized gas tank, a pressure regulator, a removable fluid container with a flexible inner bladder, and a hand-held spray gun, allowing for controlled release of the release agent without compressor air contact and enabling longer spraying times with minimal waste and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a conventional airless system with a pressurised barrel is used, then the release agent can be applied to baking receptacles, but the optimum spraying time is short and the pressure in the barrel falls below a workable level quickly
Solution Approach 1:
The system is divided into two separate containers: a pressurised gas tank and a fluid container. This segmentation allows the gas pressure to be maintained independently while the fluid is dispensed, resolving the contradiction between extended spraying time and maintaining workable pressure levels.
Solution Approach 2:
A pressure regulator device acts as an intermediary between the pressurised gas tank and the fluid container, controlling the transfer of pressure to maintain optimal spraying conditions throughout the extended spraying duration.
2Loss of substance
If a keg-based system is used, then the release agent can be stored and applied, but there is always a residue in the barrel that cannot be dispensed and compressor air contact contaminates the release agent
Solution Approach 1:
The harmful element of compressor air is extracted from the system by using a separate pressurised gas tank that does not require continuous air supply, eliminating the source of contamination and allowing complete dispensing of the release agent without residue.
Solution Approach 2:
The fluid container is designed as a disposable or replaceable component that can be completely emptied, eliminating residue waste. The container is discarded or replaced rather than cleaned and reused, ensuring no contamination from previous contents.
3Quantity of substance
If a keg-based system is used, then the release agent can be delivered and stored, but the weight of the full keg is around 45kg and it must be returned for re-filling
Solution Approach 1:
The system segments the heavy keg into a lightweight container and a separate pressurised gas tank. This allows the release agent to be delivered in a lighter container that can be easily moved and replaced, eliminating the need to return heavy kegs for refilling.
Solution Approach 2:
The system enables self-service refilling by using replaceable fluid containers that can be quickly swapped at the point of use, eliminating the need for heavy keg returns and complex refilling operations.
4Ease of operation
If air-mix systems are used, then the release agent can be sprayed, but the system complexity increases due to the need for compressed air mixing
Solution Approach 1:
The complexity of air mixing is extracted from the spray system by using a separate pressurised gas tank for propulsion, eliminating the need for compressed air mixing components and simplifying the overall system structure while maintaining ease of operation.
