Looking for superior and quicker food freezing technology for your business? Your search may end with IQF or individual quick freezing! It is a known fact that fresh produce, be it fruits, vegetables, seafood, or meat products, loose freshness over a period of time due to oxidation and microorganism growth/activity. Standard refrigeration systems do not prove efficient here.
Frozen food items have excellent quality and nutritive value. In fact in many cases, especially for green peas and sweet corn, the frozen item may have a superior taste to the fresh produce. IQF frozen fruits and vegetables appeal to businesses because of their sought-after appearance, flavour and nutrition similar to that of fresh produce. Individual quick freezing makes it possible for businesses to offer ‘freshly picked’ produce to today’s busy consumers in convenient packaging throughout the year.
Let us get into details to understand individual quick freezing.
Individual quick freezing is a special freezing method in which each and every product is frozen individually, even if multiple product types are frozen in the same area. For instance, every pea or each corn kennel is individually frozen completely and they do not lump together like a single block of ice. Instead, all products are separate from each other.
IQF is usually performed using blast freezers and is primarily used for products such as berries, peaches, french fries, chicken, shrimps, salmon, peas, corn, fish, etc.
Here are some of the benefits of individual quick freezing.
Here’s what you need to know about the working principle of individual quick freezing.
IQF involves ultra-quick freezing, i.e. the products are frozen quickly at very low temperatures for terminating the microbial activity that can lead to food spoilage. In this technology, each piece is frozen using a fluidization method in which the product is in high-velocity air. This freezes the product within a few minutes instead of three to four hours. Controlled turbulence at the start of the freezing process speeds up heat transfer and ensures fast, gentle crust freezing when the food product is most fragile. Crust freezing locks in product moisture before the final core freezing, as well as preserves product weight, appearance and quality. A unique thumbing system in the pre-cooling section avoids the lumping of pieces being frozen.
