Problems solved by technology

[0007] Judging from these conditions, the thawing machine has only a thawing method that has to accept the reduction of freshness, and there is no ice temperature instant thawing machine that can instantly reproduce the freshness of freezing. Freezing and thawing food again will inevitably reduce the quality of the food. Therefore, it is expected to develop Better thawing technology and fast instant freezer for leftover thawed food

Embodiment Construction

[0051] figure 1 It is a sectional view and a partial front view of the overall device of the freezer and thawer FT1 having an underwater ultrasonic vibrator according to the present invention. Since the object to be thawed is food, the raw material of the freezing and thawing treatment tank 1 of the above-mentioned freezer and thawing machine FT1 is preferably SUS304 or SUS316 stainless steel from small household computers to large computers for business use. In the case where the freeze-thaw treatment tank 1 is made of resin, resin products that are not harmful to health should be used in accordance with laws and regulations.

[0052] Freezing and thawing treatment tanks 1 for household use include types with built-in refrigerators, built-in water tanks, and small desktop portable types. In addition, the freezing and thawing treatment tanks 1 for business use are based on the installation location, the amount of thawing treatment of the object to be thawed, the physical prope...

Abstract

The invention provides a freezing and thawing apparatus and a thawing method for thawed food, the device can instantaneously thaw food and rapidly, instantaneously freeze the thawed food in such a manner of reproducing degree of freshness while freezing in a split second. The freezing and thawing apparatus has a freezing and thawing treatment tank for filling freezing and thawing treated water, a plurality of water ultrasonic vibrators for oscillating ultrasound different in frequency into the freezing and thawing treatment tank, a treated water cooler for cooling the freezing and thawing treated water, and a water ultrasonic vibrator control member for controlling the water ultrasonic vibrators. The invention is characterized in that the freezing and thawing treated water is ethanol added water. With the help of the ethanol added water and the water ultrasonic vibrators, the short-time thawing and rapid, instantaneous freezing can be implemented in such a manner of maintaining the degree of freshness.

Description

technical field [0001] The invention relates to a freezer and thawing machine and a thawing method for thawed objects. Background technique [0002] When thawing food, except for the food processed by the microwave oven or the instantaneous high-temperature heat generated by immersing in boiling water, all frozen processed fresh fish or edible meat can only be thawed by tap water. It takes a long time to defrost by the temperature difference caused by running water, or to defrost naturally by the temperature difference caused by moving from the freezer to the refrigerator. As a result, freshness and taste can be problematic. [0003] Therefore, if you want to shorten the thawing time, you have to increase the thawing temperature. However, if you increase the temperature, there is a risk of poor freshness and multiplication of bacteria. It will cause water evaporation and quality deterioration. In addition, even if electromagnetic waves or ultrasonic waves are emitted in t...
