Frigoscandia - Supercontact IQF Belt Freezer

• Freezing small, individual food items such as berries, peas, and prawns.
• Processing delicate products like sliced vegetables or pasta without clumping.
• Used in large-scale food production for maintaining product quality and separation.
• Suitable for products requiring rapid freezing to preserve texture and nutritional value.

Typical capacity

For this class of equipment, throughput can typically range from 500 kg/hour to several tonnes per hour, depending on product type and belt length.

Power supply

Units of this type commonly require a 3-phase industrial electrical supply, typically 400V, 50Hz, with significant power draw for refrigeration compressors and motors.

Refrigeration system

This unit is specified with an ammonia Sabroe plant, which is a common industrial refrigerant for large-scale freezing applications due to its efficiency.

Belt width

The 1m belt width on this unit is a common size, offering a good balance between footprint and processing capacity for various products.

Freezing method

Utilises a polyethylene film over a refrigerated plate, a method known for achieving quick freezing and preventing product sticking or marking.

Temperature range

IQF freezers typically operate at temperatures down to -35°C to -40°C to ensure rapid product core freezing.

Footprint

Continuous belt freezers, especially with integrated refrigeration, typically require a substantial industrial footprint, often several metres in length and width.

• What are the main benefits of an IQF freezer?

  IQF freezers rapidly freeze individual food items, preventing them from clumping together. This preserves product quality, texture, and allows for easy portioning.

• What kind of products are best suited for an IQF belt freezer?

• Is an ammonia refrigeration plant safe for food processing?

• What maintenance is typically required for an IQF belt freezer?

• Can the belt speed be adjusted for different products?

IQF systems are highly regarded in food processing for their ability to freeze individual products uniformly whilst maintaining quality and texture. Buyers typically value machines with reliable refrigeration components and consistent belt speed control. When purchasing used equipment, inspecting freezing chamber condition, verifying temperature consistency, and checking refrigerant integrity are essential. Industry users appreciate their efficiency in handling delicate items and relatively low maintenance demands compared to alternative freezing methods.
