Cooling & Drying Tunnels

The COB-DT-001 modular envelope provides the structural and hygienic framework for controlleddrying and conditioning environments. Built from insulated panel systems with sealed joints, it createsa low-leakage, vapor-tight chamber that integrates with overhead mechanical systems such as AHUs,desiccant wheels, and chilled-water coils.

This design ensures stable conditions even under heavy door traffic, with vestibule and airlock optionsavailable to reduce infiltration. Panel construction allows rapid assembly, relocation, or expansion asproduction needs grow, making it an ideal choice for both pilot plants and full-scale manufacturingfacilities.

The COB-DT-500 series rack-in room is designed for batch drying of deposited or formed candiesusing mobile racks. Operators load trays directly into the conditioned chamber, where laminar airflowand stable temperature/RH profiles drive controlled moisture migration. This prevents crusting onthe exterior while allowing the interior to equilibrate, producing a uniform texture and consistentwater activity across every tray. 

System sizing ensures that dehumidifier capacity matches the expected water load per batch (typically50–70 liters over 24 hours for a 500 kg gummy run). Multiple recipes can be staged, withprogrammable setpoints to accommodate gelatin, pectin, starch, or aerated formulations. Datalogging provides traceability for quality audits and process validation.

The COB-DT-1000 series is a high-capacity conditioning wall designed for medium to large-scaleconfectionery production. Each bay functions as a self-contained drying compartment while drawing froma centralized air handling and dehumidification system. By zoning airflow and humidity control, differentproducts or stages of the same recipe can run in parallel without cross-contamination or processinterference. 

Bays are accessed by roll-up or lift doors, allowing operators to load and unload racks efficiently whilemaintaining isolation of neighboring zones. Air distribution is engineered to maintain uniform velocityacross trays, ensuring consistent drying regardless of rack position. This modular approach reducesdowntime, as individual bays can be taken offline for sanitation or maintenance without halting the entiresystem.

The COB-DTX series is a fully integrated production line engineered for continuous manufacturing oftoffee and caramel candies. Beginning with jacketed dissolving tanks and a pre-heating stage, the systemregulates ingredient blending and transfer with automated weighing and feed pumps. A dedicated toffeecooker provides precise temperature control within ±1 °C, ensuring uniform heating that preventsscorching while achieving the ideal concentration and texture.

From cooking, the mass is deposited into silicone moulds via a servo-driven depositor with trackingtransmission, enabling pure or center-filled toffee production. Product then enters a long, zoned coolingtunnel where controlled airflow or water-assisted cooling rapidly stabilizes structure and surface finishbefore demoulding. The system is completed with automated conveying and inline packaging integration,reducing handling and improving hygienic performance.
