Special Delivery (SD) Horizontal Motion Conveyor

The Special Delivery (SD) is a mechanically driven conveyor that moves free-flowing products such as snacks, poultry, meat and vegetables with a smooth horizontal motion. The drive has no leaf springs or similar moving parts, which lowers maintenance cost and simplifies cleaning. It uses a slow-advance, quick-return (differential) motion that slides product along the pan without the vertical throw of traditional vibratory conveyors. This gentle back-and-forth movement keeps seasoning loss to a minimum and suits fragile or heavily coated products. With lengths of up to 100 ft, the SD can make very long transfers on a single drive.

The Special Delivery line

PPM's horizontal motion conveyors are built on the Special Delivery (SD) drive. The SD line offers several drive designs with three possible drive locations, and covers short modular units for distribution or scale feeding, continuous runs for long transfers, and inline storage units for accumulation. Units can be floor-mounted or suspended from existing structures. Gentle handling and easy sanitation make the line suitable for fragile and heavily coated products, and variable speed control covers a wide range of flow rates.
