Liquid Nitrogen Operated
IQF Freezing Tunnel

IQF stands for “individually quick frozen.” IQF foods are notable for the fact that each individual piece of food is frozen separately from all the others.It is the latest technolgy where instead of chilled air blast, Liquid Nitrogen (Boiling point- 196 deg celsius) is sprayed on the products.

Examples of IQF foods are fruits like blueberries, strawberries and peaches, vegetables like asparagus, soyabeans, mushrooms, pumpmkins, corn, peas, marine products like prawn,shrimp, tuna, pomfret, ribbon, sole etc, poultry products like chicken, meat, delicattesan etc. The way foods are frozen in the IQF method involves sending the individual food items on a sort of conveyor belt through a freezer where conveyor is allowed to pass under Liquid Nitrogen sprayer that freezes the item very quickly. Because the food items are separate when they go in, they stay separated after they’ve been frozen.This is the technology whereby virtually all the properties of foodstuff can be preserved. The important feature of this technology is ultra rapid freezing to a very low temparetures of -30 deg to -40 deg celsius to halt the activities of miscrorganisms that cause decay and deterioration. With IQF using Liquid Nitrogen it is now possible to preserve and store fruits, vegetables, meat and poultry products, fish and marine products for almost 2 years without compromising on taste, flavor, nutitional valus and loss of vItamins.
