AI Technical Summary

Technical Problem

In existing low-temperature ultra-fine airflow pulverization technology, powders are prone to agglomeration during the pulverization process, resulting in poor product uniformity. Furthermore, the agglomerates may be over-pulverized, affecting particle size distribution and production efficiency.

Method used

By setting up a tube between the crushing and grading processes, image recognition technology is used to obtain the particle size and dispersion of the powder. The feed rate and airflow pressure are adjusted to control the rate of repeated crushing and over-crushing. Combined with the use of surface modifiers, the process parameters are optimized to improve the uniformity of the powder.

Benefits of technology

This method improves the uniformity of powder particle size distribution, reduces over-grinding rate, reduces the amount of surface modifier used, lowers production costs, and maintains grinding efficiency.

Abstract

The invention relates to the field of image recognition, and provides a powder uniformity control method based on image recognition and an application of the powder uniformity control method in preparation of small yellow ginger whole powder in order to solve the problem of poor product uniformity caused by powder agglomeration in the crushing process in the prior art. Obtaining the relation among the inner diameter of the pipe body, the particle size of the powder and the dispersion degree of the powder, and obtaining the actual inner diameter of the pipe body; obtaining the relationship among the air inlet pressure, the first feeding speed and the particle size distribution in the pipe body in the crushing process to obtain a first array set with the repeated crushing rate smaller than or equal to a first threshold value; obtaining the relation among the second feeding speed, the repeated crushing rate and the over-crushing rate to obtain a second array set with the over-crushing rate smaller than or equal to a set value; and acquiring actual process parameters according to the first array set and the second array set. After the process parameters are obtained by adopting the control method provided by the invention, not only can the overall crushing efficiency of the process be ensured, but also the over-crushing rate can be reduced, so that the powder uniformity is improved.
