Batch Freezer Lid-Mounted Scoop Storage for Hygienic Serving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display batch freezers for ice-creams, sorbets, and slushes pose hygiene issues due to the inability to safely store scoops inside the batch freezing receptacle, leading to bacterial contamination when collecting the product, especially in warm environments.
Innovation Solution
A display batch freezer design featuring a support system with an L-shaped profile and V-notch for securely housing the scoop, where the gripping part is outside and the collecting part is inside the lid, preventing interference with the stirrer and maintaining hygiene by keeping the collecting part in a protected, cold environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scoop is kept outside the batch freezing receptacle, then the scoop does not interfere with the stirrer and the lid can close properly, but the collecting part of the scoop becomes a breeding-ground for bacteria causing hygiene problems
Solution Approach 1:
The scoop is nested within the lid structure, with the collecting part positioned inside the lid cavity and the gripping part extending outside. This nesting arrangement allows the scoop to be stored within the lid without interfering with the batch freezing receptacle or stirrer, while keeping the collecting part in a protected, cold environment to prevent bacterial growth.
Solution Approach 2:
The scoop is positioned in a third dimension by extending it through the lid, with part of the scoop inside the lid and part outside. This dimensional arrangement resolves the conflict between needing the scoop accessible for operation and needing it protected for hygiene, by utilizing the vertical space created by the lid structure.
2Reliability
If the scoop is kept inside the batch freezing receptacle, then hygiene is maintained by keeping the collecting part in a cold environment, but the scoop interferes with the stirrer and prevents proper lid closure
Solution Approach 1:
The scoop is extracted from the batch freezing receptacle and repositioned within the lid structure. This extraction removes the scoop from the operational space of the stirrer and receptacle, eliminating interference with stirring operations and allowing proper lid closure, while the collecting part remains in a protected environment within the lid.
3Ease of operation
If the scoop is placed in a hot environment outside the bench, then the scoop is easily accessible for serving, but bacterial contamination increases and ice-cream texture deteriorates
Solution Approach 1:
The scoop is nested within the lid structure, allowing the gripping part to be accessible outside while the collecting part remains protected inside the cold environment of the lid. This arrangement maintains ease of operation for gripping and serving while protecting the collecting part from bacterial contamination and temperature-related texture 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
Ensures hygienic ice-cream collection by preventing bacterial deposition on the scoop and maintaining the ice-cream's texture, while preventing damage from the stirrer and ensuring proper lid closure for motor activation.
Implementation Method 1
The batch freezer is a machine that allows transforming a liquid mixture in ice-cream by continuous stirring, cooling and the inclusion of air
Implementation Method 2
The batch freezer comprises one or more batch freezing receptacles being properly cooled, arranged horizontally or vertically, inside each of which a stirrer is rotating continuously
