Mobile unpowered energy-saving food preservation box and preservation method

Abstract

The invention discloses a mobile unpowered energy-saving food preservation box which comprises a box body, a gas cycle preservation system, a remote data monitoring and global positioning system and a solar power generation electric power storage system; the cooling capacity circulating, nano purification, enzymatic inactivation dormancy preservation technology is adopted, the energy-saving rate is high, the solar energy is used for generating and storing the power, so that the food preservation box has the function of remote movement, unpowered self-survival long-term preservation. The invention further discloses a preservation method of the mobile unpowered energy-saving food preservation box, the method can dynamically monitor, adjust and control the preservation parameter at real time according to the movement longitude and latitude of the food by pre-cooling treatment and cooling capacity nano purification preservation, the food is guaranteed at the best preservation state. The unpowered cold chain preservation of the perishable fresh food for long distance movement can be achieved through the preservation box and the preservation method and the commercial value is great.

Description

technical field [0001] The invention relates to the field of food preservation, in particular to a mobile unpowered energy-saving food preservation box and a preservation method. Background technique [0002] At present, the storage and preservation of daily edible fruits and vegetables, cooked food, fresh meat, fish and other foods, in addition to fixed storage and preservation facilities such as refrigerators, refrigerators, cold storages, and controlled atmosphere storages, there is also a container with refrigeration function. Mainly used in refrigeration and preservation during food transportation. Most of the refrigeration methods of these storage and preservation facilities adopt refrigeration units installed outside the box to drive the refrigeration evaporator installed in the box to circulate and cool the air inside the box to achieve the purpose of adjusting the space temperature in the box and keeping food fresh. [0003] However, the cooling effect of this refr...

Problems solved by technology

[0003] However, the cooling effect of this refrigeration method is greatly affected by factors such as the installation position of the refrigeration evaporator in the cabinet, the size of the evaporation area of ​​the refrigeration evaporator, the power of the air circulation, the smoothness of the air circulation ventilation channel, the volume and geometry of the cabinet, etc. Not only is the space temperature in the box uneven and fluctuating greatly, but also the refrigerating evaporator in the box is severely frosted; in order to improve the cooling effect, this cooling method often adopts a high-power refrigeration unit configuration, a large horse-drawn cart, and further increases the The frosting degree of the refrigeration evaporator has to cause a vicious cycle of "frost-defrost-frost-defrost-----", which consumes energy in vain and seriously affects the quality of food storage and preservation

In particular, due to the long and narrow geometric shape of refrigerated containers, there is often a lack of effective ventilation channels after being filled with goods. The quality of food preservation and energy consumption caused by this refrigeration method are more serious; especially the high-power equipment configuration of large horse-drawn carts, It also hinders the large-scale application of solar power generation technology with low power generation efficiency in refrigerated containers

[0004] At the same time, due to the change of the location of the refrigerated container during transportation, the ambient temperature of the refrigerated container often changes greatly. At present, the temperature inside the traditional refrigerated container mostly lacks the functions of real-time monitoring and real-time adjustment with the change of the ambient temperature. , which in turn will have a great impact on the food storage temperature in the refrigerated container. If it is not adjusted in time, it will also have a major impact on the stored food

[0005] Moreover, traditional refrigerated containers only rely on reducing the temperature of the storage space to keep food fresh, lacking other technical measures such as sterilization and purification, which have a poor effect on fresh food, especially fresh fruits and vegetables.
