Hi req-sad,

 

You will have to supply a little context, eg

 

what is the product/size/dimensions/shape of product ?

 

hopefully not surrounded by a thick layer of ice.


Kind Regards,

Hi,

 

My product is frozen pound cake. I used probe thermometer to check the core product temperature.

Actually, I want to know the right method to use the probe thermometer ie. how long should I take the temperature, or should I place the probe thermometer in the cold room while taking the reading.

 

Appreciated you all can discuss here. Thank you.

Hi req-sad,

 

I deduce this is referring to frozen product in cartons stored in a cold room ca -18degC.

 

Assuming stored product is at equilibrium with the environment, the usual, non destructive, method is to measure the temperature between contacting/adjacent cartons. This is a long established procedure in the literature, eg Codex. This is obviously an approximation to core temp. but a convenient one.

You can compare by inserting a narrow, probe into ~center of one of the cakes (i assume this is physically possible), the reaction time of a TC should be rapid.

 

IMEX, many commercial, portable, thermocouple instruments will temporarily cease functioning after a short period in -18degC environment.


Kind Regards,
