Food must be freeze dried following certain standards to be safe to eat. Before using your freeze dryer machine, carefully read the manufacturer’s instructions and follow all safety, sanitation and food-storage recommendations exactly. Never eat food that you suspect might be spoiled or may not have been freeze dried properly.
By removing residual oxygen inside packaging to below 0.01%, oxygen absorbers effectively preserve packaged foods without the need for food additives/preservatives and without the need for vacuum sealing.
Just a few years ago freeze dryers were only available commercially. As of 2025, there are now several brands and models of home freeze-dryers to consider.

Given our experience, the decision to purchase a freeze dryer again if we had a do-over is a no-brainer, we would get it every time.
Here are the key features and components of a triple pass rotary drum dryer: 1. Triple Pass Design: - The material being dried passes through three rotating drums or cylinders, hence the term "triple pass." Each drum serves a specific purpose in the drying process. 2. Material Flow: - The material enters the dryer and first passes through the innermost drum. After the initial drying phase, it moves to the middle drum and then to the outer drum, undergoing additional drying in each pass. 3. Heat Source: - Heat is typically provided by a combustion system, such as a burner or furnace, located at one end of the drum dryer. The hot gases generated by the combustion process flow through the rotating drums, transferring heat to the material. 4. Air Flow: - The dryer is designed to optimize air flow through the drums, ensuring efficient drying. In a triple pass design, the material and hot gases move counter-currently through the three drums, enhancing heat transfer and drying efficiency. 5. Lifting Flights or Lifters: - Lifters are internal components inside the drums designed to lift and cascade the material as it rotates. This movement promotes good heat transfer and uniform drying.
