Blueberries, due to the effect of protecting eyesight and strengthening resistance, are very popular and are known as the "Queen of Fruits". But blueberry particles are small, time-consuming and laborious sorting. For this reason, the FstSort blueberry sorting machine has been improved several times to better fit the characteristics of blueberries which are easily damaged in the separating process.

In the past, First Industry will suggest you to choose the normal roller grader when customers contact us for a chestnut sorting machine, similar as the cherry tomato sorting machine. But now, we prefer to suggest a new kind of drum grader, which is designed for the irregular agricultural food.

FstSort crayfish grading machine is a new attempt of the factory is to apply the machine to seafood. Recently, a customer asked about the crayfish grading machine. It grades according to the diameter of the product. Considering the uncontrollable size of the crayfish itself, we changed the machine to a traditional fixed roller. The bar grader was adjusted to an adjustable roller bar grader. This grader can expand the grading range of each grade to 15-75 mm, which greatly meets the needs of customers.

Recently, potato grader has attracted more and more attention from warehouses and farmers.The device can quickly and accurately classify potatoes into different grades according to their diameter, improving potato production and quality and reducing labor costs.Just last month, we received a request for a custom potato classifier from an Iranian customer.
