Embodiment 1

[0045] Such as figure 1 Shown is the specific arrangement of the magnetic field generating device of the specific embodiment of the present invention.

[0046] The first magnetic field generating unit is arranged on both sides of the cryogenic chamber 100 to form a steady-state magnetic field distributed along a first direction of the cryogenic chamber.

[0047] The second magnetic field generating unit is arranged on the other two sides of the cryogenic chamber to form an alternating magnetic field distributed along the second direction.

[0048] The first direction and the second direction are perpendicular to each other. That is, the directions of the steady-state magnetic field and the alternating magnetic field are perpendicular to each other.

[0049]The N pole 1 of the first magnetic field generating unit and the S pole 2 of the first magnetic field generating unit are installed on both sides of the cryogenic chamber 10 to form a steady-state magnetic field generator ...

Embodiment 2

[0053] Such as figure 2 Shown is the specific arrangement of the magnetic field generating device of another specific embodiment of the present invention.

[0054] The first magnetic field generating unit is disposed on both sides of the cryogenic chamber to form a steady-state magnetic field distributed along a first direction of the cryogenic chamber 100 .

[0055] The second magnetic field generating unit is arranged on the other two sides of the cryogenic chamber to form an alternating magnetic field distributed along the second direction.

[0056] The first direction is parallel to the second direction. That is, the first magnetic field generating unit and the second magnetic field generating unit are collinearly arranged. Certainly, in order to avoid the shielding of the alternating magnetic field by the first magnetic field generating unit, its shell is generally made of magnetically permeable material.

[0057] For example, the N pole 7 of the first magnetic field ...

Embodiment 3

[0060] Such as image 3 Shown is the specific arrangement of the magnetic field generating device in another specific embodiment of the present invention.

[0061] The first magnetic field generating unit is arranged on both sides of the cryogenic chamber 10 to form a steady-state magnetic field distributed along the first direction of the cryogenic chamber 100;

[0062] The second magnetic field generating unit further includes a rotating base 210 (that is, a rotating base formed by the base 10 and the rotating shaft base 17 ) and an alternating magnetic field generating device. The alternating magnetic field generating device is arranged on the rotating base, and is driven by the rotating base to rotate in the plane of the first direction.

[0063] The included angle between the alternating magnetic field and the steady-state magnetic field on the plane of the first direction changes with the rotation of the alternating magnetic field generating device.

[0064] Through th...

Abstract

The invention discloses a low-temperature freezing device based on a magnetic field. The low-temperature freezing device comprises a low-temperature chamber and freezing equipment related to the low-temperature chamber. The low-temperature freezing device further comprises a magnetic field generation device which comprises a first magnetic field generation unit for generating a static magnetic field and a second magnetic field generation unit for generating an alternating magnetic field. The first magnetic field generation unit and the second magnetic field generation unit are correspondingly arranged, so that a preset included angle is formed by the static magnetic field and the alternating magnetic field, and the preset compound space magnetic field is generated in the low-temperature chamber. The alternating magnetic field and the static magnetic field which are staggered by the preset angle are arranged, so that the corresponding compound space magnetic field is generated in the low-temperature chamber, moisture of moisture-containing food is kept in the original distribution state in the freezing process, moisture redistribution and loss are avoided, and the freshness degree of the food before the food is frozen can be well preserved.

Description

technical field [0001] The invention relates to the technical field of food freezing, in particular to a low-temperature freezing device based on a magnetic field and a food freezing method thereof. Background technique [0002] In the development of refrigeration technology, the freezing of hydrated items is one of the very important categories. During the refrigeration process of hydrated items, the change of its moisture content is the core issue in this field of refrigeration. For example, during the freezing process of water-containing foods (including vegetables, fruits, meat, etc.), the loss of water and the redistribution of water in the items will seriously affect the freshness and taste of water-containing foods before and after freezing. [0003] The specific reason for the above problems is that the water in the water-containing food includes bound water in molecules and free water in cells and between cells. On the one hand, bound water and free water will mov...
