Freeze dried food retains its nutritional value – One of the most remarkable things about a freeze dryer and the freeze drying process is that it does not harm the nutritional value of the food.
Most freeze dryers have a powder-coated steel exterior with a food-grade stainless steel vacuum chamber. A few brands or options have aluminum and stainless exteriors.
Freeze dried food is often confused with dehydrated food. But the two are actually very different, both in how they are produced, and the quality and shelf life of the finished product. Freeze dried food typically lasts much longer and retains more of the food’s nutrient profile and taste.
The capacity of the freeze dryer isn’t necessarily how much you can fit inside, but also includes how long it takes to freeze-dry a batch. The vacuum pump, condenser, and compressor strength can all make a difference since they reduce process time rather than increase vacuum chamber size.
Precise temperature control is critical in freeze-drying. Accessories such as thermocouples and digital temperature gauges allow users to monitor and adjust the process for optimal results across different types of materials.
Rotary drum dryers are highly efficient machines used extensively in the processing of wood chips, sawdust, and biomass. They operate by utilizing a rotating drum that heats and dries the materials as they are transported through the cylinder.
As you can see, the capacity more or less doubles with each model but the cost does not. The larger models use more energy to process the larger batches of food as well, so don’t neglect energy costs when you compare these as that impacts efficiency as we discussed earlier.

Freeze drying reduces food waste – The average American wastes nearly a pound of food every single day (7). That includes unfinished meals tossed down the garbage disposal, food left to go bad in the refrigerator, and uneaten food we leave behind in restaurants.
Removing the moisture from your food is only one step in assuring it will more info be there for you months, years or even decades down the line.
It is wonderful to freeze dry food that we have prepared. Drying the food ourselves is significantly less expensive than what we would have to pay to buy such food elsewhere. We are in control of the ingredients and are able to prepare long-term food storage that meets our needs.
Other brands, like Harvest Right, want you to contact them to make sure you get the correct parts and know how to install them. There are pros and cons for both service approaches. Maintenance parts are available at most manufacturer’s websites.
All of our experience and the testing we do to determine the best freeze dryer is useless without listing our research sources and references. We leaned on these for the book knowledge that we paired with our hands-on testing and practical prepping experience:
