An efficient method for the continuous production of a dairy-based confection
prevents protein burning and precipitation during processing. The method comprises
heating an aqueous sugar composition to at least its boiling point in a first heat
exchanger, admixing a dairy component with the boiling, aqueous sugar composition
after it exits the first heat exchanger to form a dairy-based mass, and cooking
the dairy-based mass to a desired final temperature in a second heat exchanger,
without substantial separation or precipitation of the protein within the second
heat exchanger. The first and second heat exchangers are preferably plate and frame
heat exchangers. The solids content of the dairy-based mass is preferably increased
prior to entering the second heat exchanger and again after leaving the second
heat exchanger. The solids content of the cooked, dairy-based mass is increased
to at least about 88% by weight, preferably at least about 90% by weight. An apparatus
for practicing the method of the present invention is also disclosed.
