Calibra OVA-B

The OVA-B conveyor is a flow-regulation module designed to enhance grader performance by controlling product feeding before the weighing zone. Its role is to standardize the spacing between products to maintain a consistent interval—an essential condition for stabilizing dynamic weighing and fully utilizing the machine’s throughput. Thanks to its ultra-compact design, the OVA-B integrates easily upstream of a grader, even in constrained line configurations. It is intended for food processing environments, with a design focused on hygiene and cleanability

Operating Principle

The OVA-B acts as an “active buffer” conveyor: it finely adjusts the feed speed to separate products and smooth out flow variations. The module is equipped with a synchronous motor capable of rapid speed changes, allowing real-time correction of flow irregularities. By maintaining controlled spacing, it helps reduce product interactions during weighing (overlapping, mechanical influence), which decreases weighing errors and improves repeatability.
