TL;DR
A new two-stage injection jet mixer improves pesticide and water mixing uniformity, offering better efficiency for agriculture.
Contribution
A novel two-stage injection jet mixer is introduced with verified performance and uniformity across various mixing ratios.
Findings
The mixer achieved excellent spatial and temporal distribution uniformity with deviations under 0.1%.
Root mean square error (RMSE) remained low across mixing ratios, indicating good homogeneity.
The mixer performs effectively over a wide range of ratios, supporting accurate pesticide application.
Abstract
With the mixing of water and pesticides being a critical step, which is often performed using mixers. Traditional mixers, however, frequently exhibit issues such as uneven mixing and limited ratios. A dual-stage injection jet online mixer was designed to enhance the uniformity of pesticide and water mixing. This paper presents performance tests and uniformity analysis of this mixer, aiming to assess its effectiveness post-installation and to determine if it meets the required mixing performance and uniformity standards. Image analysis was utilized for qualitative assessment, revealing that the mixer’s two-dimensional curves in both axial and radial directions matched the pattern of pure pesticides. The root mean square error (RMSE) decreased with increasing mixing ratios, ranging from a minimum of 8.57% at a 300:1 ratio to a maximum of 9.94% at 2000:1. These variations were minimal,…
