Abstract

The invention relates to the technical field of chilled food preservation, and discloses a packaging water retention device for chilled food during long-distance transportation. The device comprises ashell, wherein an air bag cylinder is fixedly installed at the upper portion of the shell, a ferromagnetic block is fixedly connected to the left wall of an inner cavity of the air bag cylinder, an air bag is arranged in the inner cavity of the air bag cylinder and located on the right side of the ferromagnetic block, an electromagnet is arranged in the inner cavity of the air bag cylinder and located on the right side of the air bag, a first spring is fixedly connected between the electromagnet and the right wall of the inner cavity of the air bag cylinder, clamping strips are arranged on the bottoms of the left wall and the right wall of an inner cavity of the shell correspondingly, a drawer is arranged at the bottom of the inner cavity of the shell, and an ice bag is arranged at the upper portion of the drawer. According to the packaging water retention device for the chilled food during the long-distance transportation, magnetic induction lines of a permanent magnet plate are cutby means of a closed coil to supply power, the ferromagnetic block is used for attracting the electrified electromagnet to move to extrude the air bag to inflate and spray water, and therefore the effects of automatic water spraying, electricity saving, water resource saving and alarm reminding are achieved.

Description

technical field [0001] The invention relates to the technical field of fresh food preservation, in particular to a packaging water retention device for long-distance transportation of cold fresh food. Background technique [0002] With the development of economic globalization, people's quality of life and living standards are improving day by day. Cold food e-commerce has become very popular. Some perishable cold food with a short shelf life will be exported to all parts of the country through refrigeration and water retention. Meet the needs of people in different regions. [0003] During the long-distance transportation of cold and fresh food, the general refrigeration and water retention device will isolate these cold and fresh food from the air at low temperature and freeze them to lock the moisture. However, during the long-distance transportation, due to the intrusion of external heat, cold The moisture in the fresh food will be evaporated gradually, and the lack of ...
