Abstract
A system for supercooling a product is provided, the system comprising: a chamber containing a supercooling medium; and disruptors that emit sound waves, ultrasound waves, and/or electromagnetic waves in the chamber; wherein during a cooling cycle the chamber reaches a cooling temperature below 0° C. and during a warming cycle the chamber reaches a warming temperature greater than the cooling temperature. The supercooling system may be used to supercool perishable products below freezing to extend shelf life and freshness of the products. Other embodiments of the supercooling system, and methods for its use, are described herein.
Claims22
A method for supercooling a product, the method comprising:
- surrounding a product in a supercooling medium until the product reaches an initial core temperature of from about −20° C. to about 0° C.;
- disrupting the formation of ice crystals within the product while in the supercooling medium using sound waves, ultrasound waves, electromagnetic waves, or combinations thereof while maintaining the initial core temperature;
- and
- warming the product from the initial core temperature to a warming temperature ranging from just below freezing to above freezing.
A system for supercooling a product, the system comprising:
- a cooling chamber containing a supercooling medium;
- a warming chamber;
- and
- disruptors that emit waves, the disruptors located inside the warming chamber and the cooling chamber,
- wherein during a cooling cycle the chamber reaches a cooling temperature of from about −20° C. to about 0° C. and during a warming cycle the chamber reaches a warming temperature greater than the cooling temperature, wherein the cooling cycle is directly followed by the warming cycle.
