Product type
Blast freezers are specialized refrigeration units designed to rapidly lower the temperature of food products. They work by circulating extremely cold air around the items, allowing for quick freezing while preserving the quality, flavor, and nutritional value of the food. Typically constructed from stainless steel and equipped with advanced cooling technology, blast freezers are essential in the food supply chain for maintaining food safety and extending shelf life.
| Temperature range | -40°C to -18°C |
| Cooling method | Air blast or plate freezing |
| Capacity | 100 kg to 5000 kg per batch |
| Power supply | Single-phase or three-phase |
