more information about IQF freezing from Wikipedia

Individual Quick Freezing usually abbreviated IQF is a freezing method used in food processing industry. Products commonly IQF with IQF technologies are typically smaller pieces of food products and can range from all types of berries, fruits and vegetables diced or sliced, seafood such as shrimps and small fish, meat, poultry and even pasta, cheese and grains. Products that have been subjected to IQF are referred to as Individually Quick IQF or IQF'd

Benefits

One of the main advantages of this method of preparing IQF food is that the freezing process takes only a few minutes. The exact time depends on the type of IQF freezer and the product. The short freezing prevents formation of large ice crystals in the product’s cells, which destroys the membrane structures at the molecular level. This makes the product keep its shape, colour, smell and taste after defrost, at a far greater extent. Another significant advantage of IQF technology is its ability to separate units of the products during freezing, which produces higher quality product compared to block freezing. This advantage is also important for food sustainability, as the consumer can defrost and use the exact needed quantity. There is a range of IQF technologies, but the main concept is to transport the product into the freezer with the help of a processing line belt or infeed shaker. Inside the freezer, the product travels through the freezing zone and comes out on the other side. Product transportation inside the freezer is by different technologies. Some freezers use transportation belts similar to a conveyor belt. Others use bed plates that hold the product, and an asymmetrical movement makes the plate advance by itself through the freezer.

Methods

There are 2 main IQF technologies: mechanical IQF freezers and cryogenic IQF freezers. Mechanical IQF freezers work on the principle of cold air circulation, which flows from underneath the bed plate or transportation belt with the help of fans. The cold airflow keeps passing through the pieces of product in circular motions while the product is also advancing through the freezer towards the exit end. The design and efficiency of this type of IQF freezers varies among manufacturers who are trying to find the perfect balance of aerodynamics for an optimal freezing result. This technology has seen impressive improvements and developments during the past 20 years, being suited for an increasing range of products. Cryogenic IQF freezers immerse the product in liquid nitrogen at very low temperatures, freezing it very rapidly while continuously moving the product to avoid block or lump formation. Even though this method shows good freezing results, it might lead to higher processing costs per kg of product due to the large amount of higher cost liquid nitrogen required. A growing demand and interest in IQF products is registered at global level due to the higher quality of these products and to the practical benefits of having separately IQF pieces. IQF is also a common pre-treatment for freeze-drying food because both processes preserve the size, taste and cell structure of the food better than methods like traditional block freezing or air drying respectively.
