Fast Speed Screw Tray Denester with Adjustable Design is an automatic tray feeding system designed to separate and release empty trays one by one from a stacked magazine onto a packaging conveyor.
It is widely used in food packaging industries, including meat, poultry, seafood, tofu, dairy products, fresh cheese, ready meals, and fresh produce packaging.
The main advantage is its synchronized screw separation mechanism, which enables high-speed tray feeding, stable positioning, and flexible adjustment for different tray dimensions.
Tray Loading: Operators place a stack of empty trays into the vertical tray magazine.
Screw Separation: Synchronized rotating screws engage the tray edges and separate the bottom tray.
Automatic Release: The separated tray drops smoothly onto the conveyor.
Positioning: The conveyor transports the tray to the filling or sealing station.
Continuous Feeding: The screw mechanism repeats the process at a controlled speed.
The adjustable design allows operators to change the denester configuration according to different tray dimensions.
Main adjustment features:
Adjustable distance between screw shafts.
Adjustable screw height for different tray depths.
Replaceable timing screws for different tray shapes.
Adjustable tray magazine guides.
Servo-controlled screw rotation and release timing.
Quick-change format settings to reduce production downtime.
Some commercial universal screw denesters offer tool-free adjustment and changeover in approximately five minutes. Actual changeover depends on the tray design and machine configuration
Feature | Advantage |
|---|---|
High-speed screw mechanism | Continuous tray separation |
Adjustable screw spacing | Different tray widths |
Adjustable height | Different tray depths |
Servo motor control | Accurate tray release |
Stainless steel frame | Hygienic construction |
Automatic tray feeding | Reduced labor |

Depending on the machine design and tray characteristics, commercial screw denesters offer different speeds.
These are indicative equipment ratings, not guaranteed production outputs. Tray shape, flange design, material, and stacking quality all affect actual speed.
