- Typical throughput
- For this class of spiral freezer, throughput can vary significantly based on product type and temperature, but units of this size commonly handle several tonnes per hour.
- Belt width
- Units like the GCP42 typically feature belt widths ranging from 400mm to over 1000mm, influencing product loading and capacity.
- Number of tiers
- Spiral freezers commonly have between 20 and 50 tiers, determining the total belt length and residence time for products.
- Refrigeration capacity
- The required refrigeration capacity for a spiral freezer of this type is typically in the range of 100kW to 300kW, depending on the specific application and product load.
- Power supply
- Industrial spiral freezers commonly require a three-phase electrical supply, typically 400V, 50Hz in the UK, with significant power draw for motors and refrigeration.
- Footprint
- While compact for their capacity, spiral freezers require a substantial floor area and height clearance, typically several metres in both dimensions.
- Operating temperature
- These freezers are designed to operate at very low temperatures, commonly down to -35°C or lower, to achieve rapid freezing.
- Maintenance requirements
- Regular maintenance includes belt cleaning, inspection of refrigeration components, and lubrication of moving parts to ensure efficient operation and hygiene.
