Area of Science:

  • Agricultural Science
  • Analytical Chemistry
  • Mechanical Engineering

Background:

  • Post-harvest sample preparation, particularly grinding, is a significant bottleneck in agricultural research.
  • Current methods using abrasive grinders like the Foss Cyclotec CT293 require time-consuming cleaning between samples.
  • Achieving uniform particle size (e.g., 1 mm) is crucial for accurate analytical assays.

Purpose of the Study:

  • To develop and evaluate a novel 3D printed adaptor for the Foss Cyclotec CT293 grinder.
  • To reduce the time required for sample preparation in post-harvest analysis.
  • To enhance the efficiency of grinding plant samples for analytical assays.

Main Methods:

  • Designed and 3D printed a custom adaptor cone for the Foss Cyclotec CT293 grinder.
  • Integrated the adaptor to eliminate the need for removing the glass container after each sample.
  • Utilized compressed air venting for automated cleaning of the abrasive ring and adaptor.
  • Conducted time-motion studies with 60 samples to quantify time savings.

Main Results:

  • The 3D printed adaptor significantly reduced sample processing time by 27% compared to the standard procedure.
  • The adaptor facilitated direct grinding of samples into various storage containers.
  • Automated cleaning with compressed air proved effective in removing residual sample material.

Conclusions:

  • The developed 3D printed adaptor is an effective solution for optimizing sample preparation in agricultural research.
  • This innovation streamlines the grinding process, saving valuable time and resources.
  • The improved workflow enhances the overall efficiency of post-harvest analytical procedures.
