压花明胶凝胶覆膜技术与花材干燥技术优化

The Optimization of the Technology of Pressed Flower Gelatin Gel Coating and Drying of Flower Material

摘要: 为了得到明胶凝胶覆膜的压花作品和立体的干燥花材，本文以各种干燥的花材和新鲜带花的迎春枝条为材料，研究明胶凝胶覆膜的具体制法及最佳配方，筛选微波立体干燥法中适合保持带花枝条形态色泽的颗粒物材质和直径。结果表明，将明胶370 g/L + 柠檬酸1.2 g/L + 脱氢乙酸钠1 g/L制成的凝胶覆盖于花材表面并将其粘贴在背景材料上，能够在增加花材韧性的同时，起到固定花材、为花材防腐、护色的作用。微波立体干燥法中以砂石颗粒为包埋介质，干燥效果较好，颗粒物的最佳直径在0.5 mm至1.5 mm之间，干燥后的花材在形态色泽上与鲜花最为接近，最具观赏性。

Abstract: In order to obtain gelatin-coated pressed flower works and three-dimensional dried flower mate-rials, various dried flower materials and fresh winter jasmine branches with flowers were used as materials to study the specific preparation method and the best formula of gelatin-coated films, and to screen the material and diameter of particles suitable for maintaining the shape and color of flower and branch in microwave three-dimensional drying method. The results showed that it could not only increase the toughness of the flower material, but also play a role in fixing the flower material, preventing corrosion and protecting color to cover the gel made of gelatin 370 g/L + citric acid 1.2 g/L + sodium dehydroacetate 1 g/L on the surface of the flower material and paste it on the background material. In the microwave three-dimensional drying method, sand and stone particles are used as embedding medium for better drying effect. The optimal diameter of particles is between 0.5 mm and 1.5 mm. The flower material after drying is the closest to flowers in shape and color, and the most ornamental.
