Fruit and vegetable transport case

Abstract

The invention relates to the field of transportation, in particular to a fruit and vegetable transport case. The fruit and vegetable transport case comprises a case body. A refrigerating chamber, a control chamber and a preservation chamber are arranged in the case body. A lockable feeding inlet is formed in the side wall of the refrigerating chamber. An insulation layer is fixed to the side wallof the refrigerating chamber. A lockable charging port is formed in the side wall of the preservation chamber. A piston capable of sliding along the side wall of the control chamber is arranged in thecontrol chamber. A gas outlet check valve communicating with the control chamber is fixed to the side wall of the refrigerating chamber. A gas inlet pipe and a gas inlet check valve which communicates with the control chamber are fixed to the side wall of the preservation chamber. The gas inlet pipe communicates with the gas inlet check valve. An exhaust check valve communicating with the refrigerating chamber is fixed to the side wall of the lower portion of the preservation chamber. A water inlet pipe with the diameter being smaller than that of the gas inlet pipe is arranged in the refrigerating chamber. The end, away from the preservation chamber, of the water inlet pipe penetrates through the refrigerating chamber and is fixed to the gas inlet pipe. A water outlet check valve communicating with the gas inlet pipe is fixed into the water inlet pipe. Fruit and vegetable can be prevented from being frozen.

Description

technical field [0001] The invention relates to the field of transportation, in particular to the field of fruit and vegetable transportation. Background technique [0002] Vegetables and fruits are rich in vitamins and minerals necessary for the human body. They are one of the essential foods in people's daily life. In order to meet the needs of consumers in different regions, fresh fruits and vegetables need to be transported from the place of production to the place of consumption. . Refrigeration is usually used to keep fresh during transportation. Due to cost considerations, during short-distance vegetable transportation, ice cubes are generally used to cool vegetables on transport vehicles. However, vegetables will be frostbitten in contact with ice cubes for a long time, and the water produced by the melting of ice cubes will rot the soaked fruits and vegetables. And along with improving day by day of people's quality of life, also constantly improve to the quality ...
