花卉是一种活性植物组织 ,采收后仍在不断发育变化。影响花卉采收后衰老、腐败的因素很多 ,其中温度是最主要的因素之一。花卉采收后由于呼吸加快 ,产生大量的附加热 ,即所谓田间热 ,田间热对花卉的贮藏和运输十分有害 ,必须迅速除去 ,使之达到规定要求的温度 ,即预冷。真空预冷是最有效的方法。花卉的品种繁多 ,各生理特性不同 ,生长环境各异 ,所以花卉的真空预冷保鲜技术十分复杂 ,本文详细介绍花卉的真空预冷保鲜的工艺和真空预冷保鲜设备
Flower is a kind of active plant tissue, which is still evolving after harvesting. Affect the flower harvesting aging, corruption, many factors, including temperature is one of the most important factor. Due to the rapid respiration of flowers after harvest, a large amount of additional heat is generated, the so-called field heat. Field heat is very harmful to the storage and transport of flowers and must be promptly removed to the required temperature, precooled. Vacuum cooling is the most effective method. Flowers of a wide variety, different physiological characteristics, different growth environments, so the flower of the vacuum pre-cooling technology is very complex, this paper details the flowers of the vacuum pre-cooling preservation process and vacuum pre-cooling preservation equipment
