Or another version of the equation is:

Q= M C (delta) T

Where Q is the amount of heat gained or lost in BTUH
M being the Mass of the object (ice cream)
C being the specific heat of the object where water is equal to ONE
and delta T being temp difference

If I were to open up my ASHRAE book, and look for specific heat of various substances under food, there would prob. be a value for milk, but don't know about Ice Cream

Assuming the Ice cream to have a number of 1.5, the mass being one pound of ice cream and the product is at 26 degree and would like it at zero degrees we would need to remove about 39 BTUh per pound/ hour
