Abstract: The present invention provides a process and apparatus for preserving the potency of a tableted heat sensitive ingredient. The process includes the steps of forming the ingredient into a tablet and cooling the tablet for a sufficient time and at a sufficiently low temperature to decrease the heat degradation of the ingredient. The process may be carried out in any number of tablet cooling apparatus, including a conduit forming a passageway for receiving tablets from the tablet press. A coolant inlet is connected to the conduit for supplying coolant into the passageway and into contact with the tablets.
