Embodiment approach 1

[0053] [1-1. Overall structure]

[0054] In this embodiment, a refrigerator will be described as an example of an apparatus for producing dried food. figure 1 It is a sectional view which shows the refrigerator in Embodiment 1.

[0055] Such as figure 1 As shown, the refrigerator main body 1 of the refrigerator 100 is partitioned by the heat insulation partition wall 2 and the heat insulation partition wall 3 in the up-down direction. Refrigerator 100 has refrigerator compartment 4 arranged in the upper part and freezer compartment 5 arranged in the lower part in refrigerator main body 1 . Moreover, refrigerator 100 has dry store room (storage compartment) 6 arranged between refrigerated compartment compartment 4 and freezer compartment 5 . Moreover, the control part 11 which controls the drive of each part and each apparatus of the refrigerator 100 is arrange|positioned in the refrigerator main body 1. As shown in FIG. An operation panel 12 is arranged in the refrigerator...

Embodiment approach 2

[0096] In this embodiment, the drying process of beef is demonstrated taking the case where beef is accommodated in the dry storage room 6 as an example. There are cases where explanations are omitted for content that overlaps with that described in Embodiment 1. FIG.

[0097] [2-1. Drying process]

[0098] First, the sliced ​​beef is placed in the dry storage room 6 by the user. Then, the user operates the switch on the operation panel 12 to select "drying process 2". And the information (for example, weight, etc.) of the beef placed is input through the food information input part 12a. Then, start the drying action.

[0099] In "drying process 2", in the temperature mode (refer to Figure 5 ) for drying and storage.

[0100] Next, use Figure 5 The temperature pattern in the drying process of this embodiment is demonstrated. Figure 5 The temperature pattern at the time of drying in this embodiment is shown. In this embodiment, with Embodiment 1 figure 2 Likewise, ...

Embodiment approach 3

[0133] In this embodiment, the drying process of a kiwi fruit is demonstrated taking the case where a kiwi fruit is accommodated in the dry storage room 6 as an example. There are cases where explanations are omitted for content that overlaps with that described in Embodiment 1 and Embodiment 2. FIG.

[0134] [3-1. Drying process]

[0135] First, the sliced ​​kiwi fruit is placed in the dry storage room 6 . Then, the user operates the switch on the operation panel 12 to select "drying process 3". And the user inputs the information (for example, weight, etc.) of the kiwi fruit arranged through the food information input part 12a. After that, start the drying action.

[0136] In "drying process 3", based on the information of the kiwi fruit input by the user, the temperature mode corresponding to the set water activity value (set water activity value) (refer to Figure 8 ) for drying and storage. Here, the temperature pattern of the drying step is set by the user selecting...

Abstract

A food drying method comprises the steps of: (a) maintaining the internal temperature of a storage zone (6) within a first temperature range ranging from -60 DEG C to -18 DEG C for a first predetermined time; (b) maintaining the internal temperature of the storage zone (6) within a second temperature range ranging from more than -18 DEG C to less than 0 DEG C for a second predetermined time; and (c) maintaining the internal temperature of the storage zone (6) within a third temperature range of 0 DEG C or more for a third predetermined time. This makes it possible to obtain a dried food that is palatable while maintaining nutritional and functional components contained in the food.

Description

technical field [0001] The present invention relates to a food drying method, a refrigerator and a storage for implementing the drying method, and a method for producing dried food. Background technique [0002] Conventionally, as a food drying method, a method of drying by heat such as hot air or microwaves, a method of drying by reducing pressure and at a low temperature, and natural drying are advantageous. [0003] In addition, there is also a drying method based on vacuum freezing in which after freezing the food, it is vacuumed by depressurizing and drying is performed by volatilizing moisture. [0004] In addition, it has been proposed to freeze food at about 0°C to about -20°C for a predetermined time, and then directly blow hot air through a heat pipe through which hot water flows to the food to dry it. According to this method, dried food can be produced inexpensively and in large quantities without impairing the original shape, appearance, and texture of the food...
