Freeze-drying is an advanced and efficient process for drying various materials. Drying occurs through sublimation and desorption, achieved by establishing low pressure and temperature in the drying chamber. The process consists of three phases: freezing, primary drying, and secondary drying. Lyophilization enables long-term storage of dried products without damaging or deforming the initial structure and composition of the sample. It is used in pharmaceuticals, industry, microbiology, and increasingly in households. Using the Solidworks CAD program, we have modeled the basic design of two different household lyophilizers with external dimensions of 595 mm x 595 mm x 567 mm. In doing so, we focused on simultaneously addressing the requirements of household appliances and the demands of the prolonged lyophilization process, considering easy and efficient control of the freeze-drying process.
