A thawing machine includes a metal member supporting a pallet on which frozen objects are placed; an electric power supply which applies an AC voltage to the metal member so that a predetermined low current of 1 A or higher and 1000 mA or lower flows through the frozen objects; and a cover unit covering the frozen objects and having an air permeability and an electric conductivity, wherein the AC voltage is applied to the cover unit in addition to the metal member while the frozen objects are thawed.

An ice processing system may include a plurality of electrodes configured to create a time-varying electromagnetic field in a cavity, and a controller configured to oscillate a density of the electromagnetic field at a frequency which depends on the temperature of an object in the cavity. The frequency is selected based on a temperature of the object to establish and maintain a resonance condition of dipoles in ice crystals present in the object, such that the electromagnetic field tends to selectively heat ice substantially without heating liquid-phase water.

The present application relates to a method for preparing processed food by means of a frozen block and processed food prepared by means of same.

Systems and methods for washing and thawing objects, such as vegetables and fruits, where large amounts of lifting of heavy items is minimized, complex and expensive pumping and manifold systems and structures are not required; and system cost and daily maintenance is reduced. The system includes a structure for holding a volume of fluid, a vertical motion structure driven by an electric motor or the like that raises and lowers a basket carrier between an elevated position and a lowered position. In the lowered position, one or more baskets are positioned on a basket carrier and are repeatedly lowered into and raised from the volume of fluid.

Provided is a high-frequency thawing apparatus that requires no setting of a thawing time and provides high precision in thawing finishing. The high-frequency thawing apparatus includes the following: a heating chamber; upper and lower electrodes with a to-be thawed object interposed therebetween, the upper and lower electrodes being disposed in parallel to each other in the heating chamber a high-frequency power source and matching circuit that applies a high-frequency voltage between the upper and lower electrodes; a power detecting circuit that detects the reflective power of the applied high-frequency voltage; and a controller that determines thawing completion, by estimating the progress status of the to-be thawed object on the basis of how a detected signal detected by the power detecting circuit has changed since thawing was started, the controller controlling the high-frequency power source on the basis of a determination.
