Lipsia Spiral Freezer 24 tiers

Lipsia Spiral Freezer 24 tiers

This used 24-tier Lipsia Spiral Freezer is designed to deliver reliable, continuous freezing performance within a compact footprint. Built for demanding industrial environments, it combines efficient airflow, precise control, and hygienic operation to ensure consistent product quality across a wide range of applications.

At the core of the system is a 335 meter spiral conveyor, providing extended dwell time while maintaining a space-efficient layout. The effective belt width of 800 mm allows stable and uniform product positioning, while the system accommodates product heights up to 118 mm—making it well suited for bakery items, prepared meals, and other temperature-sensitive products. The system is configured with an east infeed at a height of 700 mm and a north outfeed at a height of 4680 mm, allowing seamless integration into existing production lines.

The freezer is equipped with a durable Scanbelt S.201 open radius belt, specifically developed for spiral applications. Its open structure allows optimal airflow through the product layer, supporting fast and even freezing. At the same time, the belt’s mechanical strength ensures reliable handling of both delicate and heavier products.

Airflow and temperature consistency are achieved through four Güntner S-GFN 050C/810-E evaporator units, each fitted with multiple fans. Strategically positioned within the insulated enclosure, they create a balanced airflow pattern across all 24 tiers. This results in uniform freezing conditions while minimizing energy loss. The fans are controlled via ABB frequency inverter technology, allowing precise adjustment of air velocity depending on product type and load. Each evaporator is equipped with an electric defrost system, enabling continuous operation of the freezer. This ensures that frost buildup can be managed without interrupting production, supporting consistent performance and maximizing uptime.

Hygiene and cleanability are key features of this installation. The integrated belt washing system, combined with an automated Ecolab Maxxi Foamer Topax unit, enables efficient cleaning cycles with minimal manual intervention. In addition, a UV treatment system is installed at the evaporator section, actively treating the circulating airflow and helping to reduce biological buildup on the coils. This ensures that the air moving through the system remains clean, supporting high food safety standards.

Operation is straightforward and intuitive thanks to a dual-interface control system, including a Siemens SIMATIC touch panel and KOMA monitoring display. This setup provides operators with a clear overview of both the freezing process and product flow, ensuring full control at all times.

The system is powered by reliable drive technology from SEW-Eurodrive frequency inverter, ensuring smooth and stable conveyor movement. All electrical components are centrally managed within modular control cabinets.

Fully enclosed with insulated side and top panels, this spiral freezer functions as a self-contained freezing environment, optimizing thermal efficiency while maintaining strict hygiene conditions.
