FINNCOLD frozen products thawing systems operate along a PLC controlled thawing process, where temperature, air flow and humidity are controlled using temperature- (product surface-, internal temperature- and room temperature-) as well as humidity sensors. Air flow is controlled by a variable frequency drive EC-fans.
The thawing system is also supplied with cooling equipment making it possible to use the chamber for storage (max. 48 hours) when the product´s target temperature has been achieved. Storage temperature = process target temperature until the system is stopped.
The cooling equipment enables scheduled thawing (max. 48 hours). Products can be placed in the cabinet on beforehand while also setting the start time of the thawing process. In this instance the cabinet operates as a cold storage (max -6 °C) until the thawing process starts according to the set schedule.
|Size||8890 x 2800 x 3100|
|Capacity||9 – 15 euro pallets (5400 – 9000 kg) /process|
|Area of activity||
-20 °C (-18 °C) …+2 °C,
Optimal thawing process is achieved when the product´s start temperature is -20 °C (-18 °C) in case of both the scheduled process and the so called direct thawing process.
|Defrosting time||Varies by product / by packaging, indicative times:
-20 °C…- 2 °C 8 - 12 h
-20 °C…+ 2 °C 12 - 18 h
|Structure||The main electrical cabinet, cooling unit as well as water and compressed air connections for the moistening unit are installed in an integrated technical compartment.|
|Frame||Self-supporting metal subframe, 8 pcs support legs.|
|Weight||Total weight appr. 4 500 kg|
|POWER UNIT TECHNOLOGY|
|Cooling||Hermetic refrigeration compressor, refrigerant R404, cooling capacity of 7,2 kW (-8 °C / +32 °C). If the temperature of the surrounding environment exceeds +32 °C, the efficiency of the cooling compressor drops thus the thawing process is prolonged.|
|Heating||Electric resistor heating, power 60 kW|
|Air circulation||Air circulation with EC -fans (3 pcs)|
|Air flow quide||Rising and lowering with a spindle motors|
|PLC control||Control plc KOMETOS. The operating panel is located outside the container next to the door. Thawing equipment can be connected to the client’s Ethernet data network through which Kometos has the opportunity for a secure service connection.|
|Electrical connection||400 V 125 A|
|Water connection||R ½”, 4 bar|
|Compressed air supply||R ½”, 2,8 bar|
|Drain connection||Ø 48 mm|
