History of FLoFREEZE 1959 Flat steel-bed freezer FIRST IQF FREEZER was born 1960 Pilot freezer installed in Helsingborg world s first freezer with fluidisation for IQF 1962 FF-C First fluidisation freezer with continuous defrosting using glycol 1965 FF W Higher capacity with using water for continuous defrosting 1965 FF M First prefabricated freezer small size 1971 FF-MM base on FF-M principal but for higher capacity 1971 FF-S Site build freezer for high capacity French fries 1972 FF-B site build freezer with fluidisation and steal belt for wide range of products. 1975 It was introduce ADF for operation 12-14h /day 1975 FF-MA Production rationalisation and modernization of FF-M and FF-MM 1987 FF-MC for medium and high size capacity freezer with longer operation time Sequential or ADF defrosting 1988 IT WAS INSTALLED 1000 FLoFREEZER S 1992. FFMX Patented prefabricated fluidisation belt freezer for wide range of product and HYGINE DESIGN- IQF TRACK 1999 FF M and S model for replacement of FF-MC and FF-MX for entire product range in single freezer 2003 Patented Control air flow 2009 FFA new version of FFS modular segments 2010 FFM S sequential defrosting system for capacity above 7.5 t/h peas 5

New message to the market
No Seasons Fresh product all around the year
Value added product New possibilities
Application: Constant feeding The FF can not produce more than what is fed into the freezer. Constant capacity every minute Buffer Flow scale belt Counter
In the process reduce temperature by cooling water, evaporative cooling etc. Precool product (air cooling) Application: Infeed temperature
Application: Remove surface water FLoFREEZE can not IQF freeze Liquid Shaker (one /two levels) Blower Vacuum Fluidization Combination
Freezing process
Crystallization proces of water
Latent zone -crystallization
Size of ice crystals at different freezing time
Drip loss during thawing
Freezing process in two freezing zones
Temperature in the product
Dehydration during freezing process
Temperature at outfeed
Every product is unique To get best quality of product during freezing is requested special conditions WE ARE BUILDING FREEZER FOR EVERY NEED 23
Fluidization 24
Controlled Fluidisation Particles in natural formation Particles in fluidised state 25
Fluidisation support 26
The Two Zone Freezing Process C +20 Entire freezing process over two product zones Τ1 I-step Τ 2 II-step 0-18 27
FLoFREEZE IQF Track Conveyor and fluidization restriction in one piece Open hinge design for hygiene and a minimum of dead zones Modular belt for easy maintenance/replacement Optimized hole pattern for perfect fluidization Conical holes for increased hygiene Every two rods are Acetal, every two rods are ss 28
Air Pulsation 29
Air Bypass Pulsator Air flow Pulsator reduces over blow from the bed and increases airflow through the evaporator since airflow through the evaporator is not bypassed Frequency and Amplitude Evaporator Pulsator Fluid Bed Normal (pulsator closed) Time Fan Air by-pass pulsator 30
Belt Agitation 31
Application: Agitation Product: Long Irregular Juicy Sticky Negative Effect: Corals
Optimized Fluidization on First Track 33
The FLoFREEZE IQF Track Principle 1 2 3 Crust frozen product surface when leaving track 1 4 1. Product infeed 2. Track 1 3. Weir 4. Track 2 5. Track Agitation 6. Variable Fluidization 7. Pulsation 6 5 7 Air Modulators Divided pressure chambers Increased air flow in first section Better degree of IQF 34
Air Modulator Product direction It is possible to adjust the fluidization in the different parts of Track 1 by exchanging and/or relocating air modulator sheets. The different air modulator sheets are provided with different open area and thereby letting more or less air through. 35
Operating Time -ADF -Snow Handling 36
Air Defroster, ADF Longer production time, min 22 h, at rated capacity Controlled by plc Saves space of the freezer Saves refrigeration duty requirement Easy to clean Reliable 37
Air Defroster, ADF Defrosting The Air Defrost (ADF) gives greatly prolonged operating time between defrosts. Minimum 22 hour operation between defrost for most applications 38
LVS(Low Volume System) Saving energy Reducing amount of NH3 ( 1/3) Saving cost of investment in refrigeration system 39
Frigoscandia s Low Volume System Dry suction line No liquid in riser means low predictable pressure drop Liquid feed Reduced refrigerant charge in factory - about 50% of pumped system, much less than gravity No feed valves or pumps to adjust flow rates are optimised in design Small pressure drop through coil plus correct flow rate gives optimum performance
Hygiene 41
Hygiene-by-Design Open Design, open profiles All-stainless steel surfaces and easy access everywhere, make cleaning an easy job supporting full Food Safety and ensuring minimum downtime Smooth sloping surfaces, together with strategically placed hatches and drainage holes, make defrosting as easy as cleaning Tracablility on all materials in food contact 42
Hygiene-by-Design Cleaning Smooth, all-stainless steel surfaces and easy access everywhere throughout the freezer, makes cleaning an easy job. This adds up to full food safety and a minimum of downtime. 43
FLoFREEZE A IQF Freezer The FLoFREEZE A IQF Freezer provides true fluidization, thus enabling all products to be individually frozen, which results in superior product quality 44
