Whipping Device Insulating Insert Prevents Ice Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional whipping devices for ice creams and similar cold products suffer from the formation of ice due to condensed vapor on the inner walls of the cylindrical containers, leading to contamination and quality deterioration during production and storage.
Innovation Solution
An annular thermally insulating insert made of plastic material is placed inside the container to cover the upper portion of the cooled walls above the scraping blade, preventing or reducing ice formation by condensation of vapor, and a dome-shaped lid with a scoop support system is used to maintain hygiene and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cylindrical container walls are cooled to produce ice cream, then the ice cream can be whipped and stored, but ice forms on the inner walls due to vapor condensation causing contamination
Solution Approach 1:
A transparent insulating insert is introduced as an intermediary layer between the cooled container wall and the ice cream mixture. This insert prevents direct thermal contact while maintaining the cooling function, and simultaneously blocks water vapor from condensing on the cold wall surface, eliminating ice ring formation without compromising ice cream quality
Solution Approach 2:
The transparent insulating insert acts as a thin film barrier that is thermally insulating yet visually transparent. It covers the inner surface of the cooled wall, preventing vapor condensation while allowing consumers to view the ice cream production process, thus solving both the ice formation problem and maintaining product display functionality
2Productivity
If the container walls are cooled to freeze the ice cream mixture, then the ice cream can be produced, but the cooling efficiency is reduced due to ice formation on the walls
Solution Approach 1:
The transparent insulating insert serves as a thermal barrier that prevents ice formation on the container wall, maintaining consistent thermal contact between the cooling system and the ice cream mixture. By eliminating the insulating effect of ice rings, the cooling system operates more efficiently with reduced energy consumption
Solution Approach 2:
The insert changes the thermal parameters at the wall interface by providing controlled thermal insulation that prevents uncontrolled ice formation. This maintains a more stable and efficient heat transfer regime, improving overall cooling efficiency and productivity
3Illumination intensity
If a transparent lid is used to allow consumer viewing, then product visibility is improved, but hygiene and contamination prevention are compromised
Solution Approach 1:
The transparent insulating insert acts as an intermediary barrier that allows optical transmission (viewing) while providing thermal and hygienic protection. It enables consumers to view the ice cream production through the transparent material while simultaneously preventing contamination and maintaining hygiene standards
4Reliability
If the ice ring forms and dissolves during storage, then the ice cream quality deteriorates due to water flow
Solution Approach 1:
The transparent insulating insert prevents ice formation at the wall surface in the first place by blocking vapor condensation. This preliminary prevention eliminates the subsequent problem of ice dissolution and water flow, maintaining consistent ice cream quality throughout storage without contamination or quality deterioration
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
Significantly reduces the risk of ice contamination, preserving the quality of ice cream and enhancing operational efficiency and hygiene during production and storage, while being structurally simple and cost-effective for mass production.
Implementation Method 1
An annular thermally insulating insert made of plastic material is placed inside the container to cover the upper portion of the cooled walls above the scraping blade, preventing or reducing ice formation by condensation of vapor
Implementation Method 2
a ring of ice forms on the inner side of the cooled walls of the cylindrical containers of the whipping devices, above the area on which the scraping blade acts, said ring of ice being due to the condensation of water vapour on said walls
