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||7400 x 4400 x 3100 (4500)|
|Capacity||24 euro pallets (14 400 kg) / process|
-20 °C (-18 °C) … +2 °C,
Optimal thawing process is achieved when the product´s start temperature is -20 °C (-18 °C) for 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
|Cooling||Cooling by means of a cooling agent. A coolant available in the system of the plant, such as NH3, glycol, freezium or similar. The solution is pumped to the heat exchanger delivered by Kometos. The machinery contains 2 cooling blocks. Cooling capacity requirement: 25 kW. Max. temperature of the solution: -15 °C.|
|Delivery limit||The client shall supply and connect a pipeline from their own cooling system to the valves delivered by Kometos. Kometos shall deliver the required valves, heat exchangers, pumps and pipelines from the heat exchanger to the room.|
|Heating||Heating by means of a heating agent. A heated solution available in the system of the plant, such as glycol, freezium or similar. Heating capacity need: 90 kW. Minimum temperature of the solution: +40 °C.|
|Delivery limit||The client shall supply and connect a pipeline from their own cooling / heating system to the valves delivered by Kometos. The client shall provide for a possible supplementary filling of the system, if required.|
|Air circulation||Air circulation with EC-fans|
|Intermediate level / Air guide||Electromechanical spindle motors for lifting and lowering the intermediate level.|
|PLC control||Control PLC KOMETOS. The operating panel is located outside the room 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.|
