通过不同干燥速度的颗粒干燥剂的包埋干燥处理及不同的液相替代处理，研究了鲜花干制过程中的防皱问题。结果表明：适当降低颗粒包埋干燥剂的干燥速度或选择干燥速度慢的干燥剂，能有效降低干花的皱缩程度，提高干花的综合外观品质；食用精盐是本试验条件下经济有效的颗粒干燥剂；用不易挥发的有机液剂替代花材中的水分是防止干花皱缩的理想途径， Ｙ Ｔ Ｓ Ｌ是本试验条件下最理想的水分替代的最终替代物；采用逐步替代的方法并保持替代物与被替代物的交换平衡是液相替代成功的关键。
Through the embedding drying process of granular desiccant with different drying rates and different liquid phase substitution treatments, the problem of wrinkle prevention during fresh flower drying was studied. The results showed that reducing the drying speed of the embedding desiccant or selecting the desiccant with slow drying speed can effectively reduce the degree of shrinking of the dried flowers and improve the comprehensive appearance quality of the dried flowers. The edible salt is the economical and effective particle drying under the test conditions ; Substitution of non-volatile organics for the water in floral material is an ideal way to prevent the shrinkage of dried flowers. YSTL is the ideal replacement for water under the conditions of this test; a step-by-step alternative is adopted and maintained The exchange of substitutes and replacements is the key to the success of liquid-phase substitution.
