Method and machine to make large clear ice cubes for human consumption without cutting the ice

Smart overview of the Invention

An innovative ice machine has been developed to produce large, clear ice cubes without cutting, specifically for human consumption and legal sale in the United States. This machine can generate hundreds to thousands of 2-inch clear ice cubes daily, using a unique one-directional freezing method that eliminates visible impurities. The technology addresses the need for high-quality ice cubes that command premium pricing due to their clarity and size.

Technological Advancements

The invention introduces a novel method of freezing ice using an undersized liquid refrigeration line combined with agitation and an ultra-low temperature refrigerant. This approach ensures the production of clear ice cubes without dimples, bubbles, or visible cracks. The machine's design allows water to freeze uniformly from the bottom of the cavity upwards, a technique not previously utilized in the industry.

Market Impact

Clear ice cubes are in high demand, particularly in upscale establishments where visual appeal and taste experience are paramount. Traditional ice-making methods often result in imperfections due to air entrapment and impurities. This invention overcomes these challenges, producing flawless ice cubes that enhance the consumer experience and provide a competitive edge in the marketplace.

Comparison to Prior Art

Previous technologies, such as those described in Lawrence's patent, have struggled with maintaining the necessary freezing conditions and preventing visible imperfections. Unlike these earlier methods, the current invention employs ultra-cold refrigerants and precise vibration control to achieve high-quality ice. The system is designed to maintain optimal temperatures and insulation, preventing issues like frost formation on moving parts.

Additional Features

The machine is not only efficient but also emphasizes safety by using food-safe materials throughout its design. It incorporates blades capable of cutting hundreds of ice cubes without causing chips or cracks, even in varying ambient temperatures. This focus on quality and safety ensures that the ice produced is suitable for consumption and meets the highest industry standards.
