Title: Method and apparatus for reclaiming effluent from a freeze-drying process, and uses for effluent

Abstract: A system for reclaiming effluent from a freeze drying process has at least one condenser apparatus used during a freeze-drying cycle to collect effluent from material being freeze-dried, and a recovery reservoir positioned for collecting material from the condenser apparatus. The system is characterized in that ice crystals formed from the effluent are removed from the condenser after the freeze drying cycle into recovery reservoir to be re-used. Product systems include both freeze-dried material and the effluent collected during freeze drying.
