Zusammenfassung:	The present invention discloses a quick-freezing and preserving method of daylily. The quick-freezing and preserving method of the daylily comprises four steps of enzyme deactivating, cooling, quick-freezing and packaging. During the enzyme deactivating process, a steam box is heightened to solve a problem of non-uniform curing of the enzyme-deactivating of the daylily and improves enzyme-deactivating efficiency; during the cooling, processes of water cooling, dehydrating, wind cooling and dehydrating are conducted; the water cooling and wind cooling are combined; so that before the daylily enters a quick-freezing device, the daylily reaches a requirement of cooling and dehydrating after the enzyme-deactivating of the daylily; and at the same time, a problem of flower bud loosening and blooming during the cooling process after the enzyme-deactivating of the daylily is solved. 种黄花菜的速冻保鲜方法，经过杀青灭酶、冷却处理、速冻和包装四个步骤，通过将杀青灭酶过程中的蒸汽箱加高，解决了黄花菜杀青灭酶生熟不的问题，提高了杀青效率；冷却处理时采用水冷-脱水-风冷-脱水的流程，将水冷和风冷相结合，使黄花菜进入速冻装置前，即达到了黄花菜杀青灭酶后降温脱
