Reliable, Gentle Handling

The SD is a mechanically driven conveyor that utilizes smooth horizontal motion to convey free-flowing materials such as snack foods, poultry, meats and vegetables. The SD’s intelligent drive design eliminates leaf-springs and other moving parts to drastically reduce maintenance costs and simplify the cleaning process. The SD uses slow-advance-quick-return movement – also known as differential motion – to convey product smoothly along its pan without the vertical throw used by most traditional vibratory conveyors—this gentle forward-back motion ensures minimal seasoning loss and makes the conveyor especially suitable for fragile or heavily coated products. With speed rates up to 40mph and at lengths of up to 100 feet, the SD can accomplish extremely long transfers using only a single drive. Add measurable value to your production operation with PPM’s Special Delivery conveyor!

The Special Delivery Line:
Reliable, Flexible and Efficient

PPM’s family of horizontal motion conveying is built on the well-established Special Delivery (SD) drive system. In use for many years across diverse markets, the SD line offers conveyors that are reliable, efficient and simple to maintain. Featuring a variety of drive designs with three optional drive locations for multiple configurations, the SD line covers a broad range of lengths, including short modular units ideal for distribution systems or scale feeding, continuous runs for transferring over long distances, or inline storage units for product accumulation—and with the option to floor-mount or suspend from existing structures, the flexibility is endless.

Gentle handling and ease of sanitation make the SD range suitable for all products, and the units’ variable speed control allows for a wide range of production flow rates.

The Special Delivery conveyor provides a versatile solution for gentle-handling applications. Units feature a variety of options: end or intermediate drives; ceiling or floor mounting; and intermediate, end and proportional gates.

The horizontal-motion drive at the rear of the conveyor is easily accessible, and the design doesn’t use gears or oil.
