3 IQF FROZEN PRODUCT FRESHER THEN FRESH Typical Products Frozen in FLoFREEZE Freezer

4 Milestones 1950 Frigoscandia founded 1958 First IQF freezer FLoFREEZE gives birth to Frigoscandia Equipment 1965 First GYRoFREEZE delivered 1979 Introduction of GYRoCOMPACT freezer 1987 Stein Inc. in US is acquired 1988 Acquisition of DSI Inc First impingement freezer (Flat Product Freezer) delivered Frigoscandia Group put on Swedish stock exchange 1995 Frigoscandia Group acquired by ASG Sweden (transport company) 1996 Frigoscandia Group separated. Frigoscandia Equipment was sold to FMC US 2008 Spin-off from FMC to JBT Welcome to JBT 4 Foodtech

5 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 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 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

9 No Seasons Fresh product all around the year

10 Value added product New possibilities

11 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

12 In the process reduce temperature by cooling water, evaporative cooling etc. Precool product (air cooling) Application: Infeed temperature

13 Application: Remove surface water FLoFREEZE can not IQF freeze Liquid Shaker (one /two levels) Blower Vacuum Fluidization Combination

14 Freezing process

15 Crystallization proces of water

16 Latent zone -crystallization

17 Size of ice crystals at different freezing time

18 Drip loss during thawing

19 Freezing process in two freezing zones

20 Temperature in the product

21 Dehydration during freezing process

22 Temperature at outfeed

23 Every product is unique To get best quality of product during freezing is requested special conditions WE ARE BUILDING FREEZER FOR EVERY NEED 23

24 Fluidization 24

25 Controlled Fluidisation Particles in natural formation Particles in fluidised state 25

26 Fluidisation support 26

27 The Two Zone Freezing Process C +20 Entire freezing process over two product zones Τ1 I-step Τ 2 II-step

28 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

29 Air Pulsation 29

30 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

31 Belt Agitation 31

32 Application: Agitation Product: Long Irregular Juicy Sticky Negative Effect: Corals

33 Optimized Fluidization on First Track 33

34 The FLoFREEZE IQF Track Principle Crust frozen product surface when leaving track Product infeed 2. Track 1 3. Weir 4. Track 2 5. Track Agitation 6. Variable Fluidization 7. Pulsation Air Modulators Divided pressure chambers Increased air flow in first section Better degree of IQF 34

35 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

36 Operating Time -ADF -Snow Handling 36

37 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

38 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

39 LVS(Low Volume System) Saving energy Reducing amount of NH3 ( 1/3) Saving cost of investment in refrigeration system 39

40 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

41 Hygiene 41

42 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

43 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

44 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
