About Stay Fresh

How it started

Stay Fresh began in 2018 with a gap in the market: commercial freeze dryers were out of reach for families and small businesses, and the home machines on the market left a lot to be desired. Our founder, Dr. Tonghu (Tim) Jiang, holds a PhD in engineering from Johns Hopkins University and previously did research in lithium-ion battery technology. After years of hands-on research and development, including a lot of testing in a home garage, the work led to U.S. Patent 11,287,185, granted in 2022, for our freeze-drying algorithm and automation method.

How we work

We design and engineer the machines in Southern California, and QA-test every one with a full freeze-drying batch before it ships. Every machine runs our patented freeze-drying algorithm. We publish prices and full specifications, and say plainly when a different machine, or a different class of equipment, fits your job better. Owners get free technical support by phone, email and video for as long as they own the machine.

Today we build four chamber sizes, the countertop Small, the Standard, the Large and the Mega, sold direct and through resellers, with 220–240 V versions for customers across Europe and other 50 Hz markets. This site covers the configurations built for business and lab use; the home range lives at stayfreshfreezedry.com.
