Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping equipment, in particular to an electromagnetically coupled ultra-freezing temperature preservation box with an in-situ monitoring system. Background Art

[0002] Ultra-ice temperature storage technology is an ice temperature technology that has emerged in recent years. It has a long preservation time and can maintain the high quality of fresh products. It uses special techniques such as adjusting the cooling speed to maintain the temperature of fresh products in a supercooled state below the freezing point without freezing, thereby maintaining the unique flavor of fresh products. Compared with ice temperature storage, its storage period can be extended by more than 1 times.

[0003] During the ultra-freezing temperature storage process, the storage temperature is required to be between the freezing point and the destruction point of the fresh product. This temperature range is called the ultra-freezing temperature range. The ultra-freezing temperature range of different fresh products is different. Generally, the ultra-freezing temperature range of fruits and vegetables is lower, and the ultra-freezing temperature range of poultry is higher. The ultra-freezing temperature range of conventional fruits, vegetables, poultry, etc. is roughly in a temperature range between -15℃ and 0℃, and the temperature control accuracy is required to be extremely high. Traditional refrigerators generally only have a refrigeration and fresh-keeping area above 0℃ and a freezing area below -18℃.

[0004] The patent with publication number CN118000237A discloses an ultra-freezing temperature preservation device, comprising: a device body, the interior of which is a refrigerated cavity; a magnetic field generator, which is arranged at the central axis position of the refrigerated cavity of the device body, and the magnetic field generator comprises: a rotating shaft, which is connected to a driving device and rotates under the drive of the driving device; a plurality of fan-shaped permanent magnets, which are arranged, and the plurality of fan-shaped permanent magnets are successively and adjacently adsorbed on the rotating shaft in the circumferential direction to form an annular cylinder, and the magnetization directions of two adjacent fan-shaped permanent magnets are opposite, pointing to or away from the center of the rotating shaft; wherein, when the rotating shaft rotates, the direction of the magnetic field in the refrigerated cavity changes periodically, making it difficult for the polar water molecules in the cold fresh meat in the refrigerated cavity to combine into ice, so as to reduce the supercooling point temperature, thereby widening the ultra-freezing temperature zone. The device can widen the ultra-freezing temperature zone and greatly extend the storage period of cold fresh meat. However, the preservation device cannot monitor the stored items inside, and cannot determine the quality of the stored items, which easily leads to the problem that the staff is unaware of the deterioration of the stored items.
