YOUR BEST PRESERVATION OPTION. Freeze drying is easier than ever. In about a day, your food is freeze-dried, packaged and ready for a shelf-life of up to 25 years.
Patented Smart Control
Freeze drying at home has never been easier with the patented StayFresh automated freeze drying algorithm (U.S. 11,287,185).
For beginners, just prepare the food, press a few buttons, and you're all set. The machine will figure out the rest of the work to freeze dry your food. When it stops, it beeps to let you know your freeze dried food is ready!
For advanced users, there are options for you to run the drying process by trial and error in order to find the optimal solution, which can significantly reduce cost/time and increase yield in production runs.
Food safety is everyone's business.
When an oil vacuum pump is used with the freeze dryer, there is a chance that the oil mist will be drawn to the vacuum chamber. The presence of vacuum pump oil in the food poses health risks regardless of whether the oil is odorless.
The motorized ball valve in StayFresh freeze dryer remains closed when the vacuum pump is off. The vacuum pump itself comes with a check valve; therefore, the prevention of oil contamination is double guaranteed.
Stainless Steel Interior
StayFresh freeze dryer is built to last.
All key components of the freeze dryer are made of stainless steel or aluminum, which are of high strength and excellent corrosion resistance.
The more sensors, the better the outcome. It is a common industrial approach to use a probe to measure the temperature inside the food sample during freeze drying.
Though StayFresh automated freeze drying algorithm can be run without the probe, it provides insight into the status of the food being freeze dried, helps the algorithm navigate through the drying process, and improves the quality of the freeze dried product.
-40F Cold Trap
The chamber interior surface is called the 'cold trap', which captures all the water vapor during the freeze drying process.
In theory, the lower the cold trap temperature is, the better the freeze dryer performs. The cold trap in the StayFresh freeze dryer reaches -40F in a normal condition, which is suitable for most types of foods.
