Freeze dryers are essential for preserving food, pharmaceuticals, and other sensitive materials by removing moisture while retaining structure and nutrients. Whether for home use, small-scale commercial production, or industrial operations, finding the right freeze dryer is crucial. This guide explores different freeze dryer options, their key features, and trusted brands, including LTPM CHINA, a leading manufacturer offering solutions for lab, pilot, and industrial applications.
What Is a Freeze Dryer?
A freeze dryer, also known as a freeze dry machine, removes moisture through sublimation. This process freezes the product, reduces the surrounding pressure, and applies controlled heat, turning ice directly into vapor. This method is widely used to preserve food, sensitive samples, and pharmaceutical products.
