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.

An apparatus for disinfecting products is disclosed herein. The apparatus comprises a tank for holding a liquid for receiving microorganisms from the products. The tank comprises a barrier separating the tank to provide two regions of liquid, the two regions of liquid comprising a first region and a second region, wherein the first region is arranged to provide an open channel for the liquid through the tank to enable a product to be carried into, along, and out of a flowpath through the channel; and the second region holds liquid adjacent to at least one ultrasonic transducer for providing ultrasonic energy to the product via the liquid in the second region and through the barrier.

An ultrasonic freezing equipment, which includes a casing, a circulating pump system, an ultrasonic generator, a vortex-tube freezing device and a temperature-measuring device. A vertex tube is configured for refrigeration. A circulating salt solution inside the casing is configured to quickly and uniformly take away a heat of a food to be frozen, so as to efficiently freeze the food. A freezing method using the ultrasonic freezing equipment is also provided.
