IQF FREEZERS WITH TRUE FLUIDIZATION

   
   
 

True Fluidization Principle

 

EUROFREEZE IQF Freeze combine the fluidized bed principle with conveyor belts in a two-stage freezer process that offers significant benefits.
The proven advantages of fully fluidized freezing for a very wide range of products are combined in a single freezing tunnel also with the capability to freeze heavy, wet, sticky and otherwise difficult products.

This makes the EUROFREEZE IQF tunnels a flexible and verzatile freezer geared to the needs of the frozen food industry.
   
 

Two-Stage Fluidization System Gives Optimum Freezing Process:

In EUROFREEZE IQF tunnels,the products are handled in 2 zones, the crust freezing zone (belt 2). The success of the freezer is found in the combination of the two zones. Both zones are equipped with stainless steel mesh belts that serve to support heavy products .
The air flow is controlled to perfectly suit each product which gives an even temperature throughout the freezer and uniform high product quality. Thanks to fluidization in the second zone also, the result is a very versatile, efficient and reliable in-line freezer.
The feature that sets the EUROFREEZE IQF tunnels apart from the others style belt freezers is its ability to achieve a true fluization of the product where applicable. With true fluidization the product is exposed to an upward directed and controllrd polar air stream that supports and conveys that product throught the freezer. Fluidization guarantees efficient heat transfer and superior separation of product particles. On its way through the freezer each individual product is suspended separately on a cushion of air. Not only the particles freeze quickly, gently and uviformly but they freeze without damage and clustering and with minimum weight loss. This ensures true individual quick freezing (IQF) and the highest possible product quality.

The key to true fluidization is based on the perforated tray bottoms, specially selected centrifugal energy-efficient fans and pulsating air agitation system. This combination gives optimum condition for balanced and adjustable air distribution with low energy costs. Special version with single product belt to avoid droping heights for extreely sensitive products are also available

   
 

Special Belt Travel Sysem For Minimum Cleaning;

Great care has been taken in designing the belt travel system. The entire is kept within the insulated enclosure.
This means fewer penetration through the insulation and less air leakage, drastically reducing ice build-up from moisture on the belt and support rails.
There is thus no need for belt support heaters, water or any power consumption for drying the belt.

INTERNAL STRUCTURE:

The internal frame work which supports the internal platform, product conveyors, plenum chambers, evaporator, fans, etc. are produced in stainless steel .

THE INTERNAL PLATFORM is made of alumunum checker plate, allowing inspection of the freezing process and slimplifying cleaning and maintenance .
The insulated enclosure panels have a core of high density foamed polyurethane with an internal stainless steel and external painted facing to meet high requirements of gygiene as well as to allow easy, proper cleaning and optimised hygiene .

EVAPORATOR:

The evaporators are placed along the freezing zones to ensure efficient maintenance and sanitation. The coil is arranged for water and/or hot gas defrosting after operation .
The evaporator is equipped with an automatice air defrost system (ADS ) which works parallel to the freezer operation. By this feature the defrost intervals are prolonged and a higher production capacity (around 20%) per day is achieved .
The evaporator coil is made of finned steel tubes,hot dip galvanized after manufactor. The evaporator is designed for pump circulation of the refrigerant and is supplied with suction and liquid headers .

SPIRAL FREEZERS

 

EUROFREEZE

Spiral Freezing Tunnels are specialy desigened with food industy's high demands in mind, for top performance in freezing ready meals, hamburgers, fish, sea food, poultry, pizza and other bakery products.

SIPROBELT

The spiral conveyor belt is fully produced in special stainless steel. Platstic belts are also available depending on products to be processed.
The belt width and the total length of the belt is selected according to the produts and required capacities. The belt moves on special reinforced pladtic glide streips with minimum friction. CIP system, belt washer and air dryer are included in standard delivery.

All parts in contant with the products are made of stainless steel or food grade materials. The durm itself is made in segments and assembled together on site during installing. The belt side guards and support rails are mounted on the internal drum. Service hatches around the drum are also produced in stainless steel.

 

 

INSULATED ENCLOSURE:

The insulated enclosure panels have a core of high density foamed polyurethane with an internal stainless steel and external painted facing to meet high requirements of hygiene as well as to allow easy, proper cleaning and optimised hygiene.
Access to the freeze is provided by insulated doors with electrically heated gaskets. The doors are placed according to the layout of facilitate cleaning.
The well insulated freezer floor is made of fully-welded stainledd steel with sloped water drain channels and upturned edges to facilitate cleaning.
The floor is totally insulated and equipped with heating system to avoid ice build up underneath the freezer cabin.

Insulated walles, ceiling and floor are fully sealed allowing the interior of the freezer to be hosed down entirely with 4nbars water at 60 C thorough cleaning.

DRIVE MECHANISM:

The durm is driven by a adjustable speed drive motor by means of frequency converter. By changing the speed of the drum, the holding of the product can be adjusted.
The speeds of the product conveying belt and the drum are synchronized and thus the system is protected from internal frictions.
All ball bearings used in spiral freezer are specially selected to work under cold extreme conditions. The drum bearings can be oiled from one point by means of a central lubrication system.
 Belt cleaning is done by spraying water through special nozzles(CIP-System) placed on critical points.

The cleaning and drying sequence is controlled from the PLC system.

EVAPORATOR:

Coil design and dimentions are based on type of products and required capacities.
The hot dip galvanised coil is pressure tested and filled with protective gas after manufacture.
The fin spacing are arranged from large to small in the same direction as air circulation in order to minimize frost build up and thus defrost intervals are considerably prolonged.
High air volume fans are placed right under the coil. Air is sucked through the coil and vertically directed onto the products assuring the highest freezing efficiency.
Blowing of the products from the belt is avoided by means of an air balance tunnel with by-pass hatches placed at the outfeed end.
The fans are directly coupled to the electric motors. Air is sucked through aluminimum inlet cones.

Defrosting of the coil is designed both for hot gas and/or water.

INTERNAL STRUCTURE:

The internal frame work which supports the product conveyors, plenum chambers, evaporator, fans, etc are produced AISI 304 Stainless steel to ensure high hygiene as well as easy cleaning and maintenance.

Electrical Equipment:

The electrical equipment includes stainless steel cabinet with extremely operator friendly PLC touch screen control panel, wire-operatod emergency stop system together with lighting located inside the freezer.
