Effectively the freezer has two product zones, the first being known as the fluidised surface freezing zone, and the last section known as the final-freezing zone.

Fluidised Surface Freezing Zone
As the product is loaded into this section it is exposed to an upward stream of cold air, this air fluidisation guarantees efficient heat transfer and superior separation of product particles. The stainless steel conveyor belt supports the heavier products, whilst the fluidisation minimizes contact between the belt and product. The conveyor belt passes over eccentric rollers to tumble the product and prevent it clumping.
This first stage of the freezer quickly crust freezes the individual products and transfers them to the second and final zone.
The belt speed can be adjusted in this zone to vary retention times.

Final Freezing Zone
Once crust frozen the product is transferred to the second zone, which is the ‘final freezing zone’. Here the product can be loaded at a greater depth for increased efficiency. Still maintaining a certain amount of fluidisation in this zone, the belt speed is also adjustable to limit the retention time and controls the depth of the product.

Controlling the speed and depth of the product through the two zones allows a variety of products to be frozen on this versatile inline system.

The evaporators can be designed for extended running between defrosts, with sequential defrost offered as an option. Evaporators can be manufactured from stainless steel, galvanized steel or aluminium.

The conveyor system is designed to enable good access for maintenance and cleaning, and the unit conforms to the exacting standards of today’s health and safety regulations.

The smaller capacity Lomax IQF Freezers can be factory built and tested, this saves time and money on installation costs.
The larger capacity units are site built, however due to their modular design the installation time is kept to a minimum.

Lomax IQF Freezer Terminology

IQF
Abbreviation for Individually Quick Frozen

Fluidised Crust Freezing Zone
First stage of the freezer, product is uniformly loaded onto this first belt to crust freeze the product. This reduces mechanical damage when the product is transferred to the second ‘freeze’ belt.

Finished Freezing Zone
Product is held in a deep bed partially fluidized while the freezing sequence is finished.

Retention Time
This is the time taken for the product to pass through the complete freezer. This time is variable depending on size of products frozen.

Fluidised Bed
Air passing up through the belt suspends the product in the cold air stream, this minimizes contact between products and the belt and eliminates mechanical damage to the product.

Sequential Defrost
A system where a single coil block in a multi coil machine can be defrosted whilst the other coils are still freezing.

CIP
Abbreviation for ‘clean in place’.

Vibrating Rollers
A system of eccentric rollers, which vibrate the belt and prevent the product from sticking to the belt and clumping together.
