Stevens’ Rubber Grading Screens can be used to range of fresh produce, though it is our Potato Screens that are by far the most popular. Every Screen is made to order and this enables us to tweak our standard templates and make bespoke designs to suit the requirements of our customers. The Potato Screen below is an example of a custom produced design, this Grading Screen was manufactured with the intention of reducing both the downtime and the cost to the customer to repair/replace.

By creating a solid lateral strip pitched evenly along the belt, should the Screen be damaged for any reason, we are able to trim back the Screen to the nearest lateral section and splice-in a smaller section of belt. As well as keeping down time to a minimum and prolonging the life time of the Screen, this can provide a healthy saving to the customer, which is always a bonus. You should be able to notice the lateral sections in the below picture, taken before the joiners were fitted and the final clean undertaken.

About the Potato Screens
The Screen above was produced from two sections of material to create the 2,440mm width (narrower belts are formed from one slab of material), complete with 30mm Square Holes and a wider section at each edge to improve the Screen’s strength. This Rubber Grading Screen was only around four metres in length, with between 5,000 and 6,000 holes, but Screens can often be double this length and on a custom built grader conveyor design, could be up to around twenty metres long!
Interestingly, this particular order was supplied for a customer local to our Soham branch, but Stevens have supplied Potato Screens for customers all over the country and even as far afield as Israel.

Stevens’ Rubber Potato Screens are available in a range of Hole Sizes and shapes and even if it is not a standard size that you require, we may be able to produce a custom mould to suit your requirement (initial set up costs may apply). For any bespoke enquiries email or call us and we would be happy to help.
With the softness of the Rubber proving much less harsh on the product than traditional metal or plastic screens, combined with the lighter weight and easier maneuverability, the Rubber Screens really are a great option for produce grading – and especially for Potato and Onion Grading.
