Abstract

The invention relates to the technical field of food quick freezing, and discloses a permanent magnetic field-assisted freezing-based instant freezer. The instant freezer comprises a quick-freezing house, a permanent magnet generating device, wherein the quick-freezing house is provided with a quick freezing mechanism for quickly freezing food; and the permanent magnet generating device is used for generating a constant or variable permanent magnetic field, and the permanent magnetic field is used for being distributed on the food and is used for being static or moving relative to the food. On the basis of saving energy, the quick-freezing effect on the food is ensured; and the defects that in cognition of food quick-freezing by existing technicians, a magnetic field can only be applied through an electrified coil when the food is about to be subjected to phase change, the radiation range of a permanent magnetic field generated by an existing permanent magnet is relatively small, and the permanent magnetic field is difficult to cover the food well are overcome.

Description

technical field [0001] The invention relates to the technical field of quick-freezing of food, in particular to a quick-freezing machine based on permanent magnetic field assisted freezing. Background technique [0002] Freezing is a commonly used method of food preservation. It lowers the temperature of food to below -18°C, thereby inhibiting various biochemical reactions, preventing food deterioration, and extending shelf life. During the freezing process, the moisture inside the food will change from liquid to solid at around 0°C, which will cause certain damage to the quality of the food. In order to reduce this damage, it is usually by increasing the freezing rate to reduce the size of the ice crystals and reduce the mechanical damage to the internal structure of the food, but this often requires high energy consumption. [0003] With the continuous emergence of new refrigeration technologies, it has become an emerging interdisciplinary field to micro-process food by a...
