Walnut Kernel Analyzer

Introduced in 2022, WECO’s Kernel Analyzer leverages our sorting expertise in the huller and in-shell market.

The Kernel Analyzer automates color grading for processors by performing color sample tests in a matter of seconds.  Up to 100 kernels can be analyzed at one time; however, the machine can perform smaller samples by automatically ignoring empty test cups.

Initially developed to evaluate product based on the United States Department of Agriculture’s AMS color chart, the Kernel Analyzer is configurable to any color grading standard.

Additional Systems

Sensors and Devices. WECO offers devices to enhance the overall energy efficiency of your facility, reducing your fuel consumption — and your costs — by as much as 30%. Our plenum humidity monitors and environmental sensors measure the humidity and temperature in your drying plenum as well as inside and outside your building. We use that data to help you design your facility and automate the recirculation process.

AgTrack Software. Our information management system, AgTrack, helps streamline your operation as well. Designed for walnut facilities, this software allows you to record every step of the process — receiving loads, staging loads, cleaning, drying and releasing.

AgTrack also provides you with greater control over your information. Operational data that is stored in a database may be used to create trailer tickets, bin tickets, shipping manifests and customer reports, as well as to record drying times.

Users get real-time system access, robust reporting features and exceptional WECO service, along with an intuitive interface.

Other AgTrack advantage are:

  • Farm-to-processor traceability
  • Increased efficiency
  • The opportunity to differentiate your product
