Vibratory conveyors are effective for transporting a wide range of products; however, handling loose-leaf salads and delicate fresh produce presents its own challenges, such as clumping and uneven flow which can impact line efficiency.
To address these challenges, TNA’s development team designed the tna roflo® VM 3 High Throw vibratory conveyor, specifically engineered to minimise clumping and sticking when conveying produce. The system features an innovative ‘high throw’ action and a dimpled pan design that minimises surface contact which makes it particularly suitable for handling lettuce, spinach, and other leafy greens.
A key innovation of the tna roflo® VM 3 High Throw is its ‘H’ base design. Traditional conveyors often use square hangers to attach the springs responsible for vibratory motion; however, increased movement can cause these hangers to experience excessive stress, leading to frequent breakdowns. The ‘H’ base’s curved shape distributes torsional stress evenly, enhancing durability and ensuring effective vertical lift of the product. This design smooths out lumps in the product feed, maintaining consistent flow and reducing downtime associated with maintenance.
