What is IQF freezing?

IQF (Individual Quick Freezing) is a method that freezes individual pieces of food separately, preventing them from clumping together. This preserves the product's quality, texture, and appearance.

What products are suitable for an IQF freezer?

IQF freezers are ideal for a wide range of products including fruits, vegetables, seafood, poultry, and small bakery items. The key is that the product can be separated into individual pieces before freezing.

How important is the belt type?

The belt type is crucial for product handling and hygiene. GORC belts, often 2.5 mm thick and made from stainless steel, are commonly used for their durability and suitability for food contact.

What maintenance is typically required for an IQF system?

Regular maintenance includes cleaning of belts and internal components, checking refrigeration system integrity, and inspecting electrical connections. Automated belt washing systems can reduce manual effort.

Can this unit handle different products without cross-contamination?

Units with independent belt washing systems, such as in-line or periodic washing for one belt and washing during defrosting for another, are designed to minimise cross-contamination when processing different products.

Is ammonia (NH3) refrigeration safe?

Ammonia is an efficient refrigerant commonly used in industrial applications. When properly managed within a closed system and maintained according to safety standards, it is a safe and effective choice for large-scale freezing.

Typical context for this category of equipment. Always confirm specifics with the seller.

Freezing of individual fruit pieces such as strawberries, currants, raspberries, and plums.
Processing of vegetables like peas, corn, and diced carrots to maintain individual integrity.
Quick freezing of seafood products, including shrimp and scallops.
Preservation of bakery items such as pastries and dough balls.
Applications in the dairy industry for products like cheese shreds or ice cream inclusions.

Typical throughput: For this class of equipment, throughput can range significantly based on product, commonly from 2,800 kg/h for delicate items like raspberries up to 4,400 kg/h for currants, with freezing times from 7 to 35 minutes.
Cooling capacity: Units of this type typically feature a substantial cooling capacity, often around 700 kW, utilising NH3 recirculation.
Power requirements: Commonly, these systems require a 3 x 380 V, 50 Hz supply, with a maximum electrical consumption for this class of equipment often around 127 kW, including multiple fan motors.
Defrosting method: Hot NH3 steam and water spray defrosting is commonly employed, with defrosting times typically between 20-30 minutes.
Belt configuration: Units often feature multiple belts, with continuous speed control and independent washing capabilities for each belt.
Construction materials: Components in contact with product, such as belts and electrical boxes, are typically made from stainless steel to meet hygiene standards.
Footprint: For this type of industrial IQF freezer, a total length of approximately 14.2 m, a width of 5.1 m, and a height of 4.5 m is common.

IQF (Individual Quick Freezing) is a method that freezes individual pieces of food separately, preventing them from clumping together. This preserves the product's quality, texture, and appearance.

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.
