WalnutTek Moisture Monitoring Technology

WECO offers a variety of walnut moisture meters. Select the one that best meets your unique needs.

Handheld Moisture Meter. This device, which requires a worker to get a manual reading from each bin, is a practical choice for the smaller processor. 

Automated Moisture Meter. This unit consists of a series of devices that are installed in walnut bins. The moisture in each bin is displayed at a central location via computer.

Automated Moisture Meter with Door Control. In addition to the benefits of the automated moisture meter, this option features control of the air doors, which allows hot air into the bins to dry walnuts to a preset moisture limit. This control is achieved via pneumatic cylinders that are actuated by an air valve.

When all bins (up to 20) in a single row are dried, the system shuts down the burner first and then the fan. This saves energy and fuel, while also preventing over-drying of the walnuts, which decreases weight and revenue.

Automated Moisture Meter with Door Control and Bin Fill. WECO’s most comprehensive offering includes automatic fill gate oversight along with moisture monitoring and control of the air doors. Instead of requiring a worker to watch bins as they fill, this device closes the gate automatically when the fill point is reached.

Additional Systems

Sensors and Devices. WECO offers additional walnut processing devices to improve your facility’s energy efficiency. These items significantly reduce fuel consumption, allowing you to save up to 30% in energy costs. Our plenum humidity monitors and environmental sensors measure the humidity and temperature in your drying plenum as well as inside and outside your building. Data from these sensors and monitors may be used to help you design your facility and automate the air recirculation process.

AgTrack Software. AgTrack is WECO’s information management system. Designed for walnut processing facilities, AgTrack software helps streamline your operation by permitting you to record every step of the process — receiving loads, staging loads, cleaning, drying and releasing.

The software also offers greater control over your information. AgTrack stores operational data in a database that you can use to record drying times and to create trailer tickets, bin tickets, shipping manifests and customer reports.  

Along with an intuitive interface, users have real-time access to the system’s robust reporting features, as well as access to WECO’s extraordinary customer service.

Plus, AgTrack provides:

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