When you need to preserve product integrity during drying, freeze dryers provide an ideal solution. For more than 47 years, IPP has been a trusted supplier of used and surplus process equipment. With 20 complete plant sites and a massive inventory of 15,000+ pieces of process equipment, IPP offers freeze dryers ready to ship, helping companies avoid costly lead times.
Freeze dryers, also known as lyophilizers, are essential for removing moisture from heat-sensitive materials without damaging their structure. This is achieved by freezing the material and then placing it under vacuum, allowing moisture to sublimate directly from ice to vapor without passing through a liquid phase. The gentle nature of freeze drying makes it indispensable in pharmaceuticals, biotechnology, specialty chemicals, and food processing.
Freeze dryers are particularly well-suited for:
