Single grain seed weight analyser and seed weight sorter.

The elmor SWS opens new possibilities for breeding and quality control of grain, corn, oilseeds, legumes and vegetables. Moreover a variety of applications arise in environmental monitoring. Weight distributions of selected samples (kernels of individual ears, selected generations of breeding programs etc.) are determined in statistically relevant quantities, automatically and unattended. In addition, due to the possibility of sorting, a targeted selection according to the individual kernel weight (seed weight selection / seed mass selection) can be realized.

The Seed Weight Sorter (SWS) can be used as seed weight analyser for large amounts of individual kernels. It can run unattended and with high accuracy. In addition, the tested parts can be sorted. As sorting criterion, a weight limit (above / below the limit) or a window value (inside / outside the window) can be selected.

The seed weight sorter consists of an C1 counting device that runs in single grain dosing mode. The weight of each individual grain is measured using a high speed high accuracy weigh module for industrial environmental conditions from METTLER TOLEDO. This precision balance has a readability of 10 Milligram, 1 Milligram or 100 Micrograms. The rugged industry scale is largely insensitive to dust, making it suitable for tough continuous operation even in harsh environment. A pneumatic sorting cell transfers the weighted parts according to the measured weight value into one of two bins. The entire process and the storage of all weight values are controlled by a Windows-based PC. The file with all weight data can be exported via XML protocol for further processing with relevant software.

Technical data

  • For parts ranging from 2 mm to 10 mm diameter
  • Available resolutions of the scale: 10 mg, 1 mg, 0.1 mg

Modes of operation:

  • Serial weight protocolling without sorting
  • Sorting with one predetermined weight limit
  • Sorting according to the moving average
  • Sorting with two limits: inside or outside of a defined range

Obtained data when parts are sorted with one limit:

  • Number of weighted particles
  • Weight total
  • Average weight, all particles
  • Particles in the right bin
  • Weight right
  • Average right
  • Percentage right
  • Particles left
  • Weight left
  • Average weight left
  • % left
  • 1000 Grain Weight total
  • 1000 Grain Weight right

Time consumption per operation:

  • typically 2 to 4 seconds, depending on the resolution of the scale

Operational autonomy

The sorter can run unspervised for many hours. It stops when one of the following conditions is true:

  • when a preselected number of parts is weighted
  • when a preselected number is sorted into the right bin
  • when a preselected total weight is processed
  • when a preselected weight is sorted into the right bin
  • when one of the sorting bins is full.

System requirements for the control PC:

  • Operating system Windows XP, 7 or 8
  • .NET Framework 4.5 or higher
  • 2 RS232 or USB Ports

Dimensions / weight

  • W x D x H: 390 x 470 x 460mm, 25kg

Media

  • Power supply: 230 V,  50 Hz or 120 V, 60 Hz.  Other voltages / frequencies on request
  • Pressurised air: dry and clean air, 0.6 MPa (6 bar)
