UNIDEX TZF 4B

• 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.

• 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?

• How important is the belt type?

• What maintenance is typically required for an IQF system?

• Can this unit handle different products without cross-contamination?

• Is ammonia (NH3) refrigeration safe?

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.
