牡丹花护形干制工艺研究

Study on Keeping Shape of Dry Peony Flower

利用干燥剂包埋、液相替代技术及不同化学溶液后处理的方法,研究了牡丹干花制作过程中的护形问题。结果表明:用干燥剂包埋鲜花时干燥速度及干燥剂颗粒的大小是影响护形效果的一个重要因素;食用精盐是比较理想的包埋用干燥剂;不易挥发的有机液剂A是试验中最理想的液相替代法中的最终替代物;采用逐步替代的方法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;用“甘油吸入法”处理干花时选取合适的浓度和液温是达到理想软化效果的关键。

Using drier-packing ways and organic liquid substituting technique and methods of organic liquid to handle dry flowers, problems on how to keep peony shape in the process of drying were studied. The result showed that drying-rate and drier-size had great effects on keeping the shape of flowers in the experiment of packing. Edible salt with high quality was an ideal packing-drier. A was an ideal weak-volatilized organic liquid instead of water in fresh flowers. Using the methods of step-by-step replacing and balancing between substitution and substance was the key in the process of liquid substitution. The key of getting ideal softening effects on dry flowers in the experiment of glycerin-absorbed was to set fit density and temperature of glycerin.
