Nut washing

Profit from our know-how in nut processing and increase your productivity in all processes.

Clean walnuts from dirt residues.

Washing removes the layer of dirt on the walnuts.

In order to be able to dry the walnuts, the nuts must first be cleaned of dirt. This removes the layer of dirt from the nuts.

Small amounts can be cleaned with the help of our wash crate including wash sieve. For this purpose, the walnuts should be separated from the raw shells beforehand. For larger amounts, we offer our washing and calibration machine. This is a multi-functional combination device which washes and calibrates the nuts and separates them from their raw shells.

Wash crate

Clean nuts easily and simply with the washing grid.

Small amounts of walnuts can be cleaned very simply in a wash crate. A washing grid is attached to a fruit crate and the walnuts are layered on top. The sieve-like attachment can then be sprayed with a high-pressure cleaner or a similar item. The nuts should then be briefly drained and tipped into a dry container.


Details on the wash crate


  • cost-effective and efficient
  • easy to transport
  • simple handling
  • little moisture gets into the nuts
  • can also be used for other nuts

Washing and calibration machine

Cleaning, calibrating and separating shells from walnuts.

This washing machine cleans and calibrates the nuts and separates the raw shells from the nuts. In this way, the machine removes up to 95% of raw shells. To clean the nuts, a special washing drum is used (oval design). For the calibration of the nuts, the roller/drum is exchanged and replaced by a round hole sieve.

You can choose between two calibration sizes. The washing and calibration machine is driven by a standard drill. Optional nut feeder or electric motor with 230V.
