The invention belongs to the technical field of agricultural product transportation, and particularly relates to an agricultural product refrigerated transport carriage based on a vacuum technology, wherein the carriage comprises a refrigeration component, a vacuum pump and a circulation component. Air in a carriage body is pumped outwards through the vacuum pump, so that the concentration of air around agricultural products is reduced, a refrigerating unit works, the temperature of a circulating pipeline is reduced, and the temperature of the air around the circulating pipeline is reduced; meanwhile, air flowing is promoted under the action of the circulating component, the temperature of the air in the carriage body is reduced, then the temperature of the agricultural products is reduced, vacuum refrigeration of the agricultural products is achieved, the agricultural products are kept fresh in the long-time transportation process, and the quality of the agricultural products is improved; and by arrangement of the circulating component, air flowing is increased, the heat convection speed of the air is increased, the vacuum cooling speed is increased, meanwhile, continuous low temperature is kept in the carriage body, the storage effect of the agricultural products is improved, and the quality of the agricultural products is improved.

    本发明属于农产品运输技术领域,具体的说是一种基于真空技术的农产品冷藏运输车厢,包括制冷部件、真空泵和循环部件;本发明通过真空泵将车厢本体内的空气向外抽离,进而降低农产品周围空气的浓度,制冷机组工作,进而降低循环管道的温度,进而降低循环管道周围的空气温度,同时在循环部件的作用下促进空气的流动,进而降低车厢本体内空气的温度,进而降低农产品的温度,进而实现农产品的真空冷藏,进而使农产品在长时间的运输过程中保持新鲜,进而提高农产品的质量;通过设置循环部件,进而增加空气的流动,进而增加空气的热对流速度,进而提高真空的降温速度,同时使车厢本体内保持持续低温,进而提高农产品的保存效果,进而提高农产品的质量。
