(1) Color protection treatment before drying
The specific implementation method is as follows: using the solutions which could change the PH value in the cytosolic fluid of the flower, or killing the bacteria by using high temperature. These process can be used to increase the stability of the pigment, and the enzymatic activity in the material can be killed or passivated for color protection treatment. The main methods include high-temperature steam, microwave fixing, and blanching machines.
Load the roses into material carts in layers. The 6P drying and dehumidification integrated host is equipped with a 25 cubic drying room as a standard model, and about 900kg of the rose could be loaded into the drying room for once. The whole drying room can be loaded with 8 material trucks, each material truck is divided into 12-14 layers, and the layer spacing is about 8-12 cm. The material truck must use 304 stainless steel screen to avoid production pollution to the material.
