ASRS Auto Storage System Low Temp For Food And Frozen Goods Warehouses

Low Temperature ASRS Auto Storage System for Food and Frozen Goods Warehouses

１．Product Overview

This low temperature ASRS auto storage system is designed for food warehouses, frozen goods warehouses, and cold chain logistics projects that require automated pallet conveying, lifting, storage, and retrieval under refrigerated conditions. It is suitable for pallet movement between inbound stations, outbound stations, buffer sections, transfer points, and high-bay storage locations where continuous flow and controlled warehouse management are both required.

Based on the available configuration, the system can be built with chain conveyors, roller conveyors, lift transfer units, rack and pinion lifts, and pallet stacker cranes. The pallet conveying section supports 500 / 1000 / 1200 / 2000 kg load classes and operates in low-temperature environments of -25℃~5℃. For high-bay storage, the pallet stacker crane supports storage heights up to 24 m and rated pallet loads up to 2000 kg. The rack and pinion lift provides ±2 mm positioning accuracy for level transfer and interface docking.

This makes the system suitable for food and frozen goods warehouses where palletized products need automated infeed, outfeed, transfer, and storage within a low-temperature ASRS structure.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between receiving zones, buffer areas, production or transfer interfaces, storage interfaces, and outbound stations. These conveyor modules support conveying speeds of 12 / 14 / 16 m/min and can be configured according to pallet load class, warehouse rhythm, and layout requirements.

Where pallet route change is required, the lift transfer unit is used to redirect pallets between conveyor lines. Where vertical connection between different warehouse levels is needed, the rack and pinion lift provides stable level-to-level pallet transfer with lift loads of 1000 / 2000 kg and positioning accuracy of ±2 mm. For high-bay storage and retrieval, the pallet stacker crane acts as the aisle storage module, supporting automated pallet put-away and outbound retrieval.

At the control level, the system supports Industrial Ethernet communication with WMS. Addressing can be based on laser positioning or barcode positioning according to site requirements and control logic. This allows pallet conveying, transfer, storage, retrieval, and inventory-related warehouse tasks to be connected within one refrigerated ASRS workflow.

３．Specifications

４．Application

This system is suitable for food cold storage warehouses that require pallet infeed, pallet outfeed, buffering, transfer, and high-bay storage under refrigerated conditions.

It is commonly used in frozen goods warehouses, food cold chain logistics centers, refrigerated finished goods warehouses, automated pallet warehouses, and low-temperature ASRS projects where palletized products need continuous handling.

It is also suitable for warehouse layouts where pallet movement between conveyors, transfer sections, lift interfaces, and storage aisles needs to be managed as one connected automated process.

５．Processing

Pallets enter the system from the inbound conveyor line and move through chain conveyors or roller conveyors to buffer sections, transfer points, or storage interfaces.

Where route change is required, the lift transfer unit redirects pallets between conveyor paths. Where level transfer is required, the rack and pinion lift moves pallets vertically with controlled positioning.

For storage operations, the pallet stacker crane receives pallets from the storage interface, stores them in assigned rack locations, and retrieves them when outbound tasks are released. Throughout this process, WMS communicates with the system through Industrial Ethernet to coordinate pallet routing, storage assignment, inventory updates, and outbound sequencing.

６．Advantages

The system supports low-temperature operation from -25℃ to 5℃, which makes it suitable for food and frozen goods warehouses operating under refrigerated conditions.

The pallet conveying section supports 500 / 1000 / 1200 / 2000 kg load classes, allowing the system to match different pallet weights and handling requirements.

Conveying speeds of 12 / 14 / 16 m/min support continuous pallet flow between inbound, outbound, buffer, and transfer sections.

The rack and pinion lift provides ±2 mm positioning accuracy, which is useful for floor transfer, interface docking, and stable pallet handover.

The pallet stacker crane supports storage heights up to 24 m and rated loads up to 2000 kg, making the system suitable for high-bay refrigerated pallet storage.

Industrial Ethernet communication with WMS supports coordinated storage tasks, pallet movement control, and inventory-related warehouse management.

７．How to Choose

Selection should begin with pallet type, pallet size, and actual pallet load. This determines whether 500 kg, 1000 kg, 1200 kg, or 2000 kg conveyor and storage configuration is appropriate.

Warehouse temperature is another key factor. For frozen or chilled storage projects operating at -25℃~5℃, the low-temperature conveyor and transfer configuration should be confirmed together with actual frost condition, moisture level, and operating rhythm.

If the project uses high-bay racks, the required storage height and aisle arrangement should be checked to confirm whether a pallet stacker crane up to 24 m is suitable. If the warehouse includes level transfer or floor connection, the lift load and ±2 mm positioning requirement of the rack and pinion lift should also be reviewed.

Finally, WMS interface requirements, addressing method, inbound and outbound task logic, and throughput target should be confirmed before the final equipment combination is defined.
