How to Choose a Nut Screening Machine: What to Compare
Compare nut screening offers by product sample, target fractions, good-product loss and production-line connections.
Start by defining what needs to be separated
Sizing, removing broken pieces and removing foreign material are different objectives. Describe what should remain in the product and what should leave it. If you need several grades, name each output fraction. This makes the offer about the job to be done, rather than the generic name “screening machine.”
Show the supplier the product and target grades
Where possible, provide a sample from a normal production batch and examples of each desired fraction. Do not choose an opening based only on the product name: size, shape, fragility and variation in the incoming mix can affect the result. If a trial is unavailable, ask what evidence the selection will be based on.
Measure loss of acceptable product as well
Looking only at the rejected material leaves out half the picture. Record how much acceptable product goes to the wrong outlet and how much unwanted material remains in the main product. Agree on quantities and sampling method beforehand. Without these records, broad claims such as “clean separation” do not make competing offers comparable.
Ask about cleaning, changeovers and the actual line
Ask how settings or screens change between products, what areas are reached during cleaning, and how stoppages or blockages are recorded. These details vary by model and should be checked against the current drawing or machine demonstration. Also consider the operating pattern of the roasting step before the screen and packaging after it.
Close the quotation with product-specific acceptance terms
List the tested product and batch, target fractions, acceptable product loss, measurement method, included equipment and plant connections. If several products are planned, do not assume that testing one proves suitability for all. Review Sonsuz Makina’s screen and sorting-belt options, then confirm model suitability with a project-specific technical discussion.
