How does freeze-drying compare to other preservation methods? Freeze-drying retains up to 97% of the food's original nutritional content, which is superior to most other preservation methods. It also better preserves the food's original taste and texture.

Trimleaf offers a comprehensive selection of Harvest Right freeze dryers to meet every need. These include home freeze dryers and pharmaceutical freeze dryers. There are also different sizes available for each application. On top of that, Trimleaf also offers the latest innovation, the HRC100. 

But, if the lack of maintenance appeals to you more than the extra cash in your pocket, the investment in the oil-free option might seem justifiable.

Em excesso Trays: Trays usually vary by brand and model size, but if you get a whole set of extras you can prep and freeze while the freeze dryer is running for a more efficient process.

Regarding vacuum pumps, the Premier (oil) pump is much quieter than the oil free pumps. I have to listen closely to know my Premier is running. And I can buy two oil type pumps for the cost of one oil free pump.

Harvest Right replaced it, and we switched to the premier oil pump, even though we had to cover the postage.

The larger higher-capacity freeze dryers cost significantly more with the only large benefit being that they process more food at once.

Noise: The freeze dryer isn’t whisper-quiet. If you have a baby that’s a light sleeper, or if you are, putting it in a separate room might be wise.

How much food you will be freeze drying – If you plan on freeze drying small amounts of food for your future personal use, then a small freeze dryer should serve you well.

But, freeze dryers can handle a wide range of food and retain nutritional value (and flavor!) much better than dehydrators. They also give the food a massively long shelf life, extending some perishable foods to over 25 years!

The delivery experience was smooth. The freeze dryer arrived on a sturdy wooden pallet with pelo damage to the boxes, the machine, or any accessories.

Recent events have got a lot of people re-thinking their notions about preparedness. Those who never gave it much of a thought are beginning to think there might be something to the idea of having an emergency stash of food on hand.

Once frozen, the food is then exposed to a vacuum, which pulls nearly all of the moisture from it by way of sublimation (2), which transforms the ice directly into vapor, bypassing the liquid stage. By removing all but a tiny percentage of the water in a food item its lifespan is transformed from a few days to two or even three decades.
