Defrosting method

Abstract

A defrosting method capable of defrosting a frozen product uniformly, in a short time and from the inside thereof. A defrosting method for defrosting a frozen product by high-frequency heating, comprising the first high-frequency heating step of high-frequency-heating a frozen product to near a melting temperature, the temperature detecting step of measuring the temperature of the frozen product during the first high-frequency heating step and detecting that the measured temperature has reached the above melting temperature, the steam supply step of starting steam supply when the above melting temperature is detected during the above temperature detecting step to form a condensation film on the surface of the frozen product, and the second high-frequency heating step of high-frequency-heating the frozen product after the start of the above steam supply step.

Description

Technical field

[0001] The invention relates to a thawing method for thawing frozen articles by high-frequency heating. Background technique

[0002] Electronic microwave ovens that heat food by high-frequency waves (microwaves) have been widely used. Generally, an existing electronic stove is used to perform cooking by emitting high-frequency waves into the heating chamber according to the food to be heated. This kind of electric stove can be used to defrost already frozen food.

[0003] However, in the case of an ordinary electronic stove, when heating frozen items, because the heating is simply performed by emitting high-frequency waves, there is a problem that the heating temperature is very uneven depending on the size and structure of the food, which means It cannot be thawed uniformly. For example, when the food structure includes a corner, the corner is thawed first, while other parts remain frozen, resulting in part thawing and part remaining frozen. When this happens, a...
