LEESOLU dual-station tray denester machine feeds 2 trays per cycle with a single servo. Jam-free, SUS304, modular quick-change tray feeding for cartoning lines.
Looking for a high-speed tray denester that keeps your cartoning line running without jams? The LEESOLU Dual-Station Tray Denester Machine is a new-generation automatic tray feeder engineered as the front-end tray supply station for cartoning systems. A single servo motor drives two synchronized denesting stations — like twins sharing one brain — so every cycle separates, loosens and drops two trays at once, doubling your front-end feeding output.
Built on a brushed SUS304 stainless steel frame with a fully modular structure, this servo tray denester handles fresh meat, supermarket produce, snacks and other tray-packed products with food-grade hygiene and minute-level format changeovers.
✅ Modular quick change — swap modules, not machines, for new tray sizes
✅ Smart protection — PLC control, tray-empty & jam alarms, auto home reset
What Is a Dual-Station Tray Denester?
A tray denester — also called a tray destacker, tray dispenser or automatic tray feeder — separates stacked trays one by one and places them precisely into downstream cartoning, weighing or tray-sealing systems. The LEESOLU dual-station tray denester machine upgrades this concept with a twin-lane architecture: one Siemens servo motor, transmitted through timing belts and 90° bevel gears, powers eight screw-wheel assemblies in two independent denesting chambers that work in perfect sync. The result is a high-speed tray denester with fewer drive components, fewer failure points and roughly double the output of a single-lane design.

The machine suits trays with the same length and width but different heights; other tray formats are covered by swapping the modular denesting unit — making it a flexible tray feeder for cartoning machines across food industries.
5 Costly Packaging Problems This Tray Denester Solves
1. Manual tray handling = contamination risk. Hands touching food trays repeatedly creates cross-contamination risk, especially under hygiene-critical or post-pandemic standards. Solution: fully automatic denesting, feeding and dropping — a true no-touch fresh food tray denester workflow.
2. High labor cost, low efficiency. Manual tray placement is slow, inconsistent and fatigue-prone. Solution: dual stations drop two trays per servo-driven cycle, lifting whole-line capacity while cutting headcount.
3. Tray jams during continuous feeding. Poor separation causes double-tray jams and stoppages. Solution: the servo precisely controls an "feed-in → step-back" conveyor rhythm while variable-torque screw blades cut cleanly into tray gaps — jam-free, cycle after cycle.
4. Complex multi-servo designs. Conventional denesters use 2–4 independent servos: poor synchronization, high maintenance. Solution: one concentrated power source drives both stations — simpler mechanics, fewer failure points, easier service.
5. Slow changeovers, hard cleaning. Format changes and sanitation eat production time. Solution: quick-release couplings + modular denesting units for fast swaps; SUS304 with no hygiene dead corners, air-blow cleaning and quick-release washable conveyor modules.
Key Features of the LEESOLU Servo Tray Denester
1. Single-Servo Dual-Station Drive — Two Trays per Cycle
One Siemens servo motor powers both left and right denesting stations via timing belt and 90° bevel-gear transmission. Eight screw-wheel assemblies rotate in unison to complete dual-tray separation and feeding in a single motion — efficiency doubled versus single-lane machines.
Screw wheels with variable-torque helical curves and knife-edge separator plates cut rapidly into tray gaps for fast pitch-change separation. Meanwhile, micro cam followers riding in hyperboloid cam grooves drive eight layering units through separation, loosening and tray-supporting strokes — reducing denesting pressure and protecting tray integrity.
3. Automatic Tray Buffer & Feeding
Dual conveyors hold 6 tray stacks each — 12 stacks total for continuous supply. A cylinder-driven four-bar tray holder receives and releases stacks smoothly by gravity; the servo-controlled "one stack in, one step back" rhythm guarantees reliable tray-to-tray separation. Tray-empty and jam alarms enable fully unattended operation.
4. Modular Quick-Change Design
The entire denesting module detaches via quick-release couplings for instant power disengagement. Swap modules for new tray specifications, rotate modules 90° for orientation changes, and fine-tune with adjustable guide rods and positioning rods — changeover in minutes, not hours.
5. SUS304 Food-Grade, Easy-Clean Construction
Brushed 304 stainless steel frame with no hygiene dead corners; daily cleaning by air gun alone. Conveyor modules release quickly for deep washing; actuators are waterproof and structural parts use 304 / water-resistant materials. An optional anti-condensation waterproof electrical cabinet makes it a reliable cold-room tray denester for chilled and high-humidity environments.
6. Mobile Design & PLC Smart Control
Lockable casters allow easy relocation for floor cleaning. The PLC orchestrates every motion with adjustable servo rhythms, automatic home-position reset for repeat-accurate starts, and simple pneumatic assist circuits — fewer electrical parts, faster maintenance.
How the High-Speed Tray Denesting Cycle Works (6 Steps)
Manual tray loading
Operators stack trays onto the left and right conveyors (6 stacks each, 12 total), positioned against the long guide plate.
Automatic tray feeding
The servo-driven conveyor advances one stack into the tray holder, then steps back a set distance to guarantee stack separation; the cylinder four-bar mechanism receives and releases trays by gravity for continuous supply.
Screw-wheel denesting
Eight screw-wheel sets (4 per side) rotate in two independent chambers; variable-torque helical curves and knife-edge plates cut into tray gaps for rapid, positive separation.
Cam layer separation
Cam followers travel the hyperboloid cam grooves, driving eight layering units through separation, loosening and supporting strokes so trays release layer by layer, smoothly.
Dual-tray drop
Left and right trays, guided on all four sides by 12 guide rods, drop synchronously into the downstream cartoning system — two trays per cycle.
Empty-tray detection & auto refill
If no tray drop is detected after a cycle, the system auto-releases a new stack and refills the conveyor; if the buffer runs empty, an alarm prompts reloading. Unattended continuous running supported.

FAQ — Dual-Station Tray Denester Machine
Q1: Which cartoning systems can this tray denester connect to?
A: It is designed as the front-end automatic tray supply station for all types of automatic cartoning systems — weigh-pack tray lines, fresh food packing lines, portion-count packing lines and more.
Q2: How many tray stacks can I load at once? Do I need to refill frequently?
A: Six stacks per conveyor, 12 in total. The machine feeds continuously and alarms when the buffer runs low, so no frequent manual refilling is needed in normal production.
Q3: How fast is a format changeover?
A: Trays with the same footprint but different heights only need guide-rod adjustment. Different tray specifications require swapping the modular denesting unit — the quick-release coupling disengages power in seconds, dramatically cutting changeover time.
Q4: Can it work in cold rooms or humid environments?
A: Yes. With the optional waterproof electrical cabinet equipped with an anti-condensation device, moisture and condensate are expelled from the cabinet. The SUS304 body and waterproof actuators handle chilled, washdown and high-humidity conditions.
Q5: Is cleaning easy and food-safety compliant?
A: The brushed SUS304 body has no hygiene dead corners and cleans with an air gun; conveyor modules detach for deep washing. The design meets food packaging hygiene standards.
Q6: How much more efficient is dual-station vs. single-station?
A: One cycle delivers two trays, so theoretical output is roughly double a single-lane denester — while the single-servo layout keeps the structure simpler and more reliable than multi-servo alternatives.
