This multi-frequency sorting machine is specifically designed to remove contaminants and leave you with high quality grapes. 

Dionysos uses NIR (Near InfraRed) technology for Visible Color analysis, Chlorophyll analysis, Translucency analysis and Shape analysis. NIR detects imperfections inside the produce, whilst Visible Color detects colour defects on the outside, such as yellowing, damage, etc.

Chlorophyll analysis provides deep accurate detection in chlorophyll-high produce. Translucency analysis enables detection of stones and contaminants on the belt side of the produce. Shape analysis detects small pieces of fruit or vegetable and removes them.

This means that the following contaminants are removed swiftly:

  • rotten grapes, even if they have the same color of the good ones
  • stalks, leaves and, if requested, green grapes
  • any type of plastic, irrespective of the color
  • any kind of insect
  • dry grapes

Ejection can be a single grading system or, in 3Way mode, Dionysos can differentiate between pure waste and second grade produce.

What our customers say

Since mid-2016, we have implemented the preventative service package. A recent internal review has highlighted that the service costs have nearly been neutralised by the drop-in breakdown repair/parts costs. The impact on the business is that downtime on the machines has become minimal to insignificant.
