Commercial description The First Cold Chain FSL500 is an industrial spiral freezer designed for food-processing plants requiring rapid and continuous freezing with a nominal capacity of up to 500kg/h. This capacity was calculated by the manufacturer using a stuffed pastry containing 100g of ground beef per unit and measuring Ø14cm as the reference product, so actual throughput can be adapted according to the type, format and thermal characteristics of the food being processed. Its spiral conveyor system incorporates 12 levels and 140m of total belt length, enabling continuous product flow within a compact footprint while providing an adjustable residence time of 10–50 minutes. Variable-frequency speed control allows the freezing process to be adapted to different products and production requirements. The commercial configuration includes a refrigeration unit equipped with a 125HP Bitzer HSN8571-125Y screw compressor, sized to operate with the freezer and reduce product temperature from approximately +15°C to –18°C while maintaining an internal freezer operating temperature of –35°C. The system can be integrated into industrial lines handling a broad range of foods, including meat products, burger patties, sausages, breaded products, bakery products, dough and filled pastry products, prepared meals, processed foods, fish and seafood, fruits and vegetables, provided their dimensions and process requirements are compatible with the conveyor and maximum product height. It is also suitable for manufacturers seeking to automate the freezing stage between food preparation and packaging operations. Key advantages include its 500kg/h nominal capacity, 140m conveyor arranged across 12 spiral levels, continuously adjustable freezing time, SUS304 internal construction, 150mm insulated enclosure and included Bitzer refrigeration unit. Emergency stops at inlet and outlet, IP55 electrical protection and water defrosting complement the system for continuous industrial operation.
