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.
Every can you put on the shelves is full of liquid, which accounts for most of its weight and the space it takes up. Freeze dried food takes up a fraction of the space of cans, and less space than dehydrated foods too.
You can see our full list of review criteria below in the What to Look For section, with an explanation for each.
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.
Our oil pump gave out before we had used it more than a few weeks. It was a hassle to get it fixed and three months later it quit freezing and we had to send the whole machine back. And that was MONTHS ago! I lost my summer and fall harvest because they simply couldn’t be bothered to do anything about it.
While there are many places to get a freeze-dryer, you are likely to have some issues with it. If you’re a first-time buyer, you want something reliable. Don’t think that saving a few hundred makes it a good deal. Here's why certain platforms might not be the best choice:
Energy efficiency has become increasingly important in newer freeze dryer models, with improved vacuum pump designs and optimized refrigeration systems that reduce operating costs.
You can get better energy efficiency by getting a larger Shop Now capacity model from Harvest Right or another brand, but you won’t be coming anywhere near this price point. This model is also still relatively small and can fit on a counter or a cart.
Proper trays ensure even distribution of the material being dried and facilitate efficient moisture removal.
Hi, I’m Sean and I’ve been reviewing freeze dryers for several years now. As a manufacturing engineer and as an emergency manager, I have the background to approach the comparison, review, and testing of freeze dryers from a uniquely broad perspective.

Freeze drying is a great idea if you have a garden – Oftentimes, people with vegetable gardens produce a surplus that either goes to waste, or is given away before it goes to waste.
Vacuum pumps and other moving parts in freeze dryers require regular lubrication. Accessory kits containing the appropriate oils and lubricants are essential for maintaining these critical components and preventing wear and tear.
Vacuum pumps are crucial because they create the low-pressure environment necessary for sublimation to occur in freeze-drying. They help remove air and moisture from the chamber, allowing for efficient and effective preservation of materials.
