MQF Spiral Freezer & Cooler

Used for cooling and freezing bulk or packaged products across a wide 200–5,000 kg/h range. The single-drum spiral tunnel is designed strictly around your process and user criteria, tailored to your line flow and product type.

For cooling and freezing bulk or packaged products at medium-to-high capacities (1,000 kg/h and above). The ideal solution for products that need long retention times, delivering efficient results for high-sensitivity products requiring low infeed and low outfeed.

They are utilized for the cooling and freezing of both bulk and packaged products across a wide capacity range of 200 to 10,000 kg/hour, making them suitable for use across all industries. The belt edge and the drum are engaged together like a gearwheel system, meaning the system is mechanically driven directly by the drum. Furthermore, since there is no friction between the belt and the drum, overdrive is completely eliminated, thereby preventing any operational issues caused by belt tension. At the same time, DDS (Direct Drive System) technology ensures more hygienic conditions, reduces washing frequencies, and lowers operational costs. With this technology, higher capacities of products can be transported under lower belt tension. The Direct Drum Drive Spiral Freezing Tunnel is custom-designed with single or double drum configurations, completely taking into account process and user criteria.

These systems are utilized for the cooling and freezing of products with low product heights, such as nuggets, burgers, and packaged ready meals. Specially designed, self-supporting belts that stack on top of each other are used in this configuration. Consequently, the support structures used in traditional spiral systems are not required, allowing for significantly higher freezing and cooling capacities within the same footprint. Thanks to its robust drum structure and Direct Drive operating principle, it is perfectly suited for high-capacity production facilities. Compared to structure-supported spiral systems, it can be cleaned much faster and ensures utility efficiency by consuming significantly less water.

MQF Side Drive technology represents spiral systems that do not require a drum for movement. Instead, sprockets are strategically positioned at optimal locations along the edges of the belt. These sprockets operate like a rack-and-pinion system, converting rotational movement into linear motion. Operating as intermediate drives along the conveyor run, these sprockets make this technology the perfect solution for oval-shaped loops and long, complex conveyor configurations.

This system is utilized in the bakery, ready meals, and confectionery sectors to reduce the core temperature of baked and cooked products. The MQF Spiral Ambient Cooler System is custom-designed strictly in accordance with process requirements and user-defined criteria. As products advance in a spiral path on the belt, they are cooled evenly using ambient air. This prevents product deformation, optimizes moisture retention, and preserves the final product quality, flavor, and shelf life.
