I can make a very simple interface user in Excel like your template and develop the mathematical model of this process.
In addition to calculating the temperature of the cold surface for a given time, also it can be programmed the reverse calculation, given a cold surface temperature, calculate the cooling time.
I propose the following activities that I can do for this price:
(1) develop the heat transfer mathematical model of this process. This is explained brief in a Word document in 2 pages or less.
(2) automated spreadsheets very simple able to compute the cold surface temperature for a given time. Also the reverse calculation.
(3) include the database of thermal properties (density, heat capacity, thermal conductivity) of several candy materials and included in this Excel template. You can using this data base through simple controls. Websites and books where I seek this information will be provided to you.
