Tray Handling

Tray Denesters designed and manufactured by Waldrop Company provide an economical method of dispensing a variety of stacked trays onto your production line. In the marketplace for a number of years, our denesters are proven products that can dispense trays at high throughput rates with repeatable accuracy. Whether you are a baked goods supplier packaging cup cakes, or a poultry producer packaging fresh meat products, these items can benefit your operation.

Our tray denesting units are constructed of Grade 304 stainless steel. These units are suitable for placement in harsh wash-down environments. Numerous tray shapes are supported including: rectangular, square, round, oval, and octagon – virtually any shape available in the marketplace. Tray compositions supported include foam, surgical plastic trays, plastic “tubs”, paperboard, etc.

Some of the benefits and features of our denesters include:

  • Full integration into your existing packing line. Our denesters can function as a standalone units incorporated into your existing packing line equipment or purchased as a complete solution with custom conveyors and automated loaders.
  • Increased throughput. The Denester will pace the line – the line will not be driven by the speed of individual packer personnel.
  • Increased cleanliness of trays. Unit eliminates contact between line personnel and tray.
  • No contact to inside of tray. Pre-padded trays do not present a problem as on standard vacuum pick and place denesters.
  • Fully wash down units.

  • Lower operating costs. The unit requires minimal spare parts, which means no costly replacement parts or downtime.
