Concezione di stoccaggio pallet ad alta densità

Stop paying to cool empty air.

In the cold chain and food processing sector, your most expensive operational cost isn’t the inventory—it’s the cubic meter of -25°C air you struggle to maintain. Traditional floor stacking creates “honeycombing,” leaving massive gaps in your freezer while forklifts hemorrhage thermal energy through open dock doors.

Our high-density shuttle designs trade single-pallet selectivity for maximum volumetric efficiency, reducing your energy footprint by eliminating the aisles you don’t need.

The Economics of Frozen Air: Why Density is Destiny

In standard ambient warehousing, density is about saving land. In cold storage, density is about survival. Every square foot of a freezer warehouse that isn’t occupied by product is a liability on your P&L statement. The traditional aisle-heavy layout requires you to refrigerate vast open spaces just so a forklift can turn around.

The Concezione di stoccaggio pallet ad alta densità employed by Starack fundamentally changes this equation. We utilize a Satellite Shuttle system carried by a stacker crane. Instead of the crane reaching into the rack, it deploys a remote-controlled shuttle that travels deep into the racking structure—often 4 to 10 pallets deep.

Hardware Logic: The Starack-Shuttle Advantage

Implementing high density in a sub-zero environment requires more than just tighter racks. It requires metallurgy and engineering designed for thermal contraction.

Structure: We utilize Q355 high-strength steel with a fully bolted structure. We avoid site welding, which is prone to brittle fracture at low temperatures and introduces rust points. The bolted design allows the rack to “breathe” slightly during thermal cycles without compromising rigidity.
Logic: The system supports LIFO (Last-In, First-Out) or batch FIFO (First-In, First-Out). This is ideal for food processors producing large batches of the same SKU (e.g., frozen french fries or ice cream) where individual pallet selectivity is less critical than maximizing tonnage per cubic meter.
Integration: By adopting a Rack Clad Warehouse design, the racking itself supports the insulated roof and wall panels. This eliminates the need for a separate structural steel building, reducing construction time and creating a tighter thermal envelope.

Sanitary Compliance and Throughput

High density cannot come at the cost of hygiene, especially in food and pharma. One of the hidden risks in deep-lane storage is the stagnation of air or the difficulty in cleaning. The Starack design mitigates this through specific “clean-design” profiles.

For pharmaceutical clients or high-grade food producers, our Automated Pallet Storage System integrates directly with WMS to manage expiration dates strictly. Even in a dense, multi-deep channel, the system tracks the batch code of every pallet. When an order comes in, the logic engine ensures the oldest valid stock is retrieved first, preventing the “buried inventory” syndrome common in manual block stacking.

Regenerative Energy: Turning Gravity into Electricity

In a 30-meter tall automated warehouse, lowering a 1,000kg pallet generates significant kinetic energy. In older systems, this energy was dissipated as heat—exactly what you don’t want in a freezer.

Starack systems come standard with Regenerative Braking Units. When the carriage lowers or decelerates, the motor acts as a generator. This energy is fed back into the DC bus to power horizontal travel or returned to the grid. For high-throughput cold storage, this feature alone can reduce overall energy consumption by 20-30%, contributing to Energy efficient warehouse systems that meet modern carbon standards.

From Honeycombing to 99% Utilization

Consider a beverage bottling plant. In a floor-stacking scenario, if you have a lane capable of holding 10 pallets but you only have 3 pallets of “Lot A” left, that lane is effectively blocked. You cannot place “Lot B” on top or in front without burying “Lot A.” This is the “honeycomb effect,” and it often results in warehouses that look full but are actually at 60% capacity.

The Starack Shuttle system solves this. The WMS automatically consolidates partial lanes during off-peak hours (night shifts). The machine grooms the inventory, pushing same-SKU pallets together to free up complete empty lanes for the next production run. This “housekeeping” function is impossible with manual labor but effortless for an automated system.

Domande frequenti

1. How does the shuttle system perform in -25°C environments?
Standard batteries fail in deep freeze. We utilize supercapacitors or low-temperature specific lithium batteries with internal heating elements for the shuttles. The stacker crane itself uses cold-resistant cabling and lubricants formulated to remain viscous at sub-zero temperatures.

2. What happens if a shuttle breaks down deep inside the rack?
The Starack system includes a specialized “Rescue Shuttle.” The stacker crane retrieves the rescue unit, which is deployed into the lane to mechanically latch onto the disabled shuttle and tow it out to the crane for maintenance.

3. Can this design handle different pallet sizes (e.g., Euro vs. Industrial)?
High-density shuttle systems are generally designed for a uniform pallet footprint to maximize safety. However, we can design the “Slave Pallet” or system pallet approach, where your varying load types are placed on a master system pallet for internal handling.

4. Is the rack-clad structure certified for high wind or seismic loads?
Yes. Since the rack is the building, we calculate wind shear and seismic loads as part of the structural engineering. We use Q355 steel and specific bracing patterns to ensure the 40m tall structure meets local building codes (like IBC or Eurocode 3).

5. What is the typical ROI timeline for a cold storage AS/RS?
Due to the high cost of energy and land in cold chain logistics, the ROI is typically faster than ambient warehouses—often between 3 to 4.5 years. This calculation includes energy savings, labor reduction, and the avoidance of land acquisition costs.
