Abstract

The invention relates to an image analysis method for a spray freezing coating effect based on Image J, which comprises the following steps of: 1) a picture acquiring process, namely shooting a tray filled with inert carrier particles by using a high-definition camera, and storing the picture; shooting the no-load tray, and storing a picture; 2) an image processing process: utilizing Image J software to calculate a quantitative relation between the number of pixel points of the picture and millimeter, and setting the unit length of the picture; cutting out a to-be-processed part in the picture; dividing the colors of the pictures into 256 types, and converting the cut pictures into 8-bit pictures by utilizing Image J software; converting the 8-bit pictures into a binary image by utilizingImage J software; counting an image area ratio occupied by a black region in the binary image to obtain a projection area of spray freezing coating; and 3) a coating effect analysis process; accordingto the present invention, the spray freezing coating picture shot by the high definition camera is processed and analyzed to obtain the inert carrier particle surface coating effect, the result is reliable, accurate and objective, the operation is simple, and the implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of image analysis, in particular to an image analysis method for spray freezing coating effects based on Image J. Background technique [0002] In today's society, people's economic level is improving day by day, and the demand for high-nutrition, high-value-added products is also rising, and spray freeze-drying technology has unique advantages in preparing such products. Spray-Freeze Drying (SFD for short) is a new type of drying technology that atomizes liquid materials through an atomizer and then freeze-dries the atomized droplets to obtain powder products. In the process of preparing powder products with SFD technology, the materials are kept at a lower temperature, which can effectively ensure that the commercial value of some heat-sensitive materials will not be lost, but the heat and mass transfer rate is low under low temperature conditions, making the SFD technology The drying time is longer, whic...
