Octofost IQF 6/2 RH

OctoFrost IQF 6/2 LH Tunnel Freezer, practically new, operating on ammonia (NH3). The tunnel has only worked for 100 hours.

IQF stands for Individually Quick Freezing—technology specifically designed for rapid freezing of small food items. This process prevents the formation of large ice crystals within products such as vegetables, berries, cheese, meat, and fish. The freezer is equipped with a loading/unloading station, control panels, evaporators, and a Siemens Simatic control panel. Additionally, we can supply other refrigeration technology, such as compressors and condensers. Please contact us for further details!

Products are loaded onto the infeed conveyor at a height of approximately 1560 mm. They are then transported through the OctoFrost via a vibratory belt, which includes a unique separation section to evenly separate product and remove excess ice. The belt measures approximately 8,100 mm in length and 850 mm in width. Once the required core temperature is reached, the product exits the freezer at a height of 1250 mm. There are three inspection hatches for quality control at the belt.

The OctoFrost is fitted with two NH3 evaporators, which ensure product freezing to a desired core temperature of -18°C. The unit comes with six centrifugal fans, each directly driven by an ABB M3AA 132 MB electric motor (50 Hz, 11 kW, 1450 rpm, 630 mm diameter). These fans force air from below, through the belt perforations, preventing products from sticking to the belt during freezing. For easy cleaning and inspection of evaporators and fans, the side panel slides out.

The system features a dedicated control cabinet, incorporating six ABB frequency converters for conveyors, three Key Technology MFS 268 XL frequency converters for belt vibration control, and a Siemens control panel for overall freezer management.
