About Stay Fresh: Empowering Home Food Preservation

Stay Fresh Technology is proud to be an American company based in Los Angeles, California. Founded by engineer and U.S. patent holder Dr. Tonghu Jiang, our mission is simple: to provide dependable, high-quality freeze-drying solutions that are both affordable and built to last—right here in the USA.

Our Story

Our journey began in 2018 when we recognized a serious gap in the market. Commercial freeze dryers were out of reach for most families and small businesses, while existing home models left much to be desired. We believed there had to be a better option—something more durable, efficient, and affordable. So, we rolled up our sleeves and built one ourselves.

After years of hands-on research and development, we developed a powerful, compact freeze dryer designed for both home and small-business use. This innovation led to the award of U.S. Utility Patent No. 11,287,185 B1 for our proprietary freeze-drying algorithm and automation method.

Innovation You Can Trust

At Stay Fresh, we are committed to delivering products that reflect American innovation, craftsmanship, and integrity. All our freeze dryers are designed, engineered, and tested in our Southern California facility. We prioritize:

• Durability: Built with robust materials to handle serious capacity and long-term use.

• Precision: Our patented smart algorithms automatically manage temperature, pressure, and timing for consistent, professional-grade results.

• User Empowerment: We believe in putting the power of food preservation into your hands, whether you are a homesteader, gardener, small-batch snack maker, or adventurous home cook.

Staying Fresh: A Mindset

“Stay Fresh” is more than just our name; it’s a commitment to freshness in both food and independence. Our machines allow you to hold on to what matters: the taste of a summer tomato, the crispness of garden herbs, and the satisfaction of knowing that your homemade meals will remain delicious and nutrient-rich for years to come.

In a world of mass-produced goods, Stay Fresh reminds us that technology can serve self-sufficiency. We don’t just provide equipment; we provide the tools to build a lifestyle rooted in quality, control, and confidence. Join us in taking food preservation to the next level.
