Overview
The small IQF freezer (Individual Quick Freezing) is a compact industrial rapid-freezing unit designed to freeze food products individually while preserving shape, texture and nutrients. Suitable for dumplings, buns, spring rolls, meat, seafood, vegetables, dairy and prepared meals. Ideal where floor space is limited and consistent frozen quality is required.

Freezing performance
The unit can reduce product core temperature to below -18°C / -45°C / -60°C / -80°C within 30 minutes depending on product size and load. Rapid passage through the 0°C to -5°C ice-crystal formation zone minimizes structural damage and nutrient loss.

Applications

• Frozen dumpling and pastry factories
• Meat and seafood processing plants
• Vegetable and fruit freezing lines
• Dairy and dessert production
• Ready-to-eat and pre-cooked meal manufacturers
• Supermarkets with on-site frozen food production

Why choose a Small IQF Freezer?

• Simple operation and maintenance
• Adapted to limited workshop space
• Short payback for small processing lines
• Consistent product quality and portion separation
• Reduced dehydration and nutrient degradation
