Embodiment approach 1

[0043] figure 1 It is a schematic diagram showing the difference between the freezing method of rice and the conventional rice freezing method in particular, in the freezing preservation method of food according to Embodiment 1 of the present invention, figure 2 It is a graph showing the texture of rice frozen by the frozen preservation method of the food, image 3 It is a graph showing the temperature change when water freezes, (a) without overcooling, and (b) with overcooling.

[0044]The cryopreservation method proposed as Embodiment 1 of the present invention is suitable for freezing foods containing starch such as rice in a state of better quality, and is particularly suitable for freezing rice.

[0045] Moreover, even if it is food other than food containing starch like rice, as long as it is a warm food, the effect of improving the frozen quality can be acquired.

[0046] Hereinafter, taking rice as an example, the cryopreservation method and implementation means wil...

Embodiment approach 2

[0136] Figure 12 It is a perspective view showing a conversion box of a freezer-refrigerator implementing the freeze-preservation method according to Embodiment 2 of the present invention, Figure 13 It is a perspective view showing another conversion box of the freezer-refrigerator implementing the freeze storage method.

[0137] In the above-mentioned first embodiment, the freezing control proposed by the present invention can be performed in the entire conversion box 201 accommodated in the conversion chamber 200 , but in this second embodiment, only the conversion box 201 accommodated in the conversion chamber 200 The specific section carries out the freezing control proposed by the present invention.

[0138] The advantage of carrying out the freezing control of the present invention only in a specific section in the conversion box 201 of the conversion chamber 200 is that the position of the food that is put into the temperature can be specified to reduce the chance of...

Abstract

The invention aims to save labor to remove residual heat and to improve quality after refrigeration and thawing by cooling a warm food such as steaming rice in a concentrated manner and having the food go through a supercooled state when being frozen. In a freezing method for food for refrigerating food containing starch such as rice, rapid cooling is conducted at a cooling speed of 0.5 DEG C. / minute or more when the food temperature is high, the rapid cooling is stopped so as to decrease the cooling capacity when a temperature on the food surface falls within a temperature range of 40 to 10DEG C., and when the food temperature reaches the vicinity of a freezing point temperature thereafter, the cooling capacity is raised within a range such that an air temperature around the food does not fall to -15DEG C. or below for rapid cooling, and after rapid cooling is conducted again after a predetermined time has elapsed, regular refrigeration is conducted.

Description

technical field [0001] The present invention relates to a food freeze preservation method and a freezer-refrigerator utilizing freeze preservation technology. Background technique [0002] In recent years, in home-use refrigerators, opportunities to freeze cooked cooked rice at home have increased. Originally, rice tastes the best when it is cooked, but it takes time and effort to cook only the required amount of rice when needed. [0003] Therefore, freezing and storing rice at home has become common as a simple and convenient storage method, similar to keeping warm in a rice cooker. [0004] However, if considering the situation that the extra cooked rice is kept warm in a rice cooker and divided into multiple meals, the kept rice will turn yellow after some time, or dry and harden, or have a strong taste. Equally delicious to eat. [0005] Therefore, as the device that overcomes these problems, in the past, there is the container that comprises accommodated rice, the r...
