Precision Ice Block Cutting for Uniform Clear Ice Cubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice making machines produce ice cubes with trapped bubbles and lack uniformity, leading to suboptimal quality and consistency.
Innovation Solution
A method involving the use of high-purity ice blocks, precision cutting in a controlled freezer environment using a band saw with polymer blade cleaners and food-grade white oil to produce uniformly sized ice cubes, followed by snow removal and packaging in a refrigerator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional ice making machines are used, then ice production is simple and quick, but the ice contains trapped bubbles and lacks uniformity
Solution Approach 1:
The ice block is divided into multiple sub-blocks, which are then further segmented into sheets, loins, and final ice objects through sequential cutting operations. This multi-stage segmentation approach enables precise dimensional control and uniformity while maintaining a manageable manufacturing process
Solution Approach 2:
The ice block undergoes preliminary trimming of all sides to ensure smooth, straight cuts before being cut into sheets and loins. This preliminary action establishes a uniform base geometry that ensures consistent final dimensions and appearance across all ice objects
2Manufacturing precision
If conventional ice making machines are used, then the process is fast, but the ice quality lacks transparency and clarity
Solution Approach 1:
Snow is removed from the ice objects after cutting to eliminate surface imperfections and trapped bubbles. This extraction of harmful elements (snow and bubbles) from the ice structure enhances transparency and clarity while maintaining production efficiency through a dedicated post-processing step
3Manufacturing precision
If precision cutting is performed on ice blocks, then uniform ice objects are produced, but multiple cutting steps increase processing time
Solution Approach 1:
The cutting process continues uninterrupted from trimming sub-blocks through cutting sheets, loins, and final ice objects without removing the ice from the freezer. This continuous operation within the controlled freezer environment maintains ice integrity and dimensional precision while minimizing total processing time

AI summary
A method of manufacturing uniform ice objects includes placing an ice block in a freezer; cutting the ice block into sub-blocks, in the freezer; trimming all sides of each sub-block to ensure smooth, straight cuts on all sides thereof, in the freezer; cutting each trimmed sub-block into sheets, in the freezer, to define a final height of ice objects; cutting each sheet into loins, in the freezer, to define a width of the ice objects; cutting each loin into the ice objects, in the freezer; loading the ice objects in tubs, in the freezer; relocating the tubs of ice objects from the freezer to a refrigerator; removing snow from the ice objects and packaging the ice objects, in the refrigerator; and returning the packaged ice objects to the freezer.
