Octofost IQF 6/2 RH

Virtually new Octofrost IQF 6/2 LH tunnel freezer operating with ammonia (NH3), with only 100 working hours. IQF stands for Individually Quick Freezing, a method specifically designed for rapid freezing of small food products. This process effectively prevents the formation of ice crystals within products like vegetables, berries, cheese, meat, and fish. The freezer is equipped with a feeder/discharge conveyor, control panels, evaporators, and a Siemens Simatic control panel. Additionally, we can supply other refrigeration technologies such as compressors and condensers. Please contact us for further information!

Products are placed onto the feeding conveyor at a height of approx. 1560 mm. They are then conveyed through the Octofrost by a vibratory belt. The belt features a separation section for product singulation and excess ice removal. Belt length is approx. 8100 mm with a width of 850 mm. Once frozen to the required core temperature, products exit the freezer at a height of 1250 mm. The freezer includes three inspection openings for in-process quality control.

The OctoFrost is fitted with two NH3 evaporators ensuring the product reaches the desired internal temperature of -18°C. The unit is equipped with 6 centrifugal fans, each directly driven by ABB M3AA 132 MB electric motors (50 Hz – 11 kW – 1450 rpm – 630 mm diameter). These fans deliver air from below, through the belt perforations, preventing the product from freezing onto the belt. The side panel is retractable for convenient inspection and cleaning of evaporators and fans.

Furthermore, the Octofrost comes with a dedicated control cabinet, which includes 6 ABB inverters for the conveyors, 3 Key Technology MFS 268 XL frequency converters for belt vibration control, and a Siemens touch panel for freezer management.
