The complete cycle typically requires 20-36 hours depending on water content and food density, resulting in perfectly preserved items that retain their original shape, color, and nutritional profile.
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.
For those on a budget, the premier oil pump’s upfront cost seems much more reasonable. It’s a significant saving, one that could go towards purchasing more food for preservation and storage equipment such as Mylar bags.
While not absolutely necessary for all operations, temperature monitoring tools can significantly improve the quality and consistency of freeze-dried products.
We did not include those riser racks in our capacity calculations and comparison since they aren’t true tray capacity.
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.
On your Mylar bags, don’t cheap out. You can’t afford cheap for other than items that you intend to be stored for only a short time. Too, though I have an impulse sealer, I find a cheap hair straightener works better.
Freeze drying maintains nearly all of the nutritional value of fresh food. Other methods of preservation, such as canning and dehydrating, use high temperatures that destroy much of the food value.
Freeze dryers need to run a vacuum and get very, very cold in order to preserve the food. It uses a lot of energy to do this and can take a long time to freeze-dry a batch of food.
Buying a freeze dryer for a candy business would be a questionable business decision at this point. The market is now saturated with endcaps in grocery stores covered in freeze-dried treats, and margins have been driving lower. The lower cost of freeze dryers means competitors pop up more often.
Now we adopt the, “if it ain’t broke, don’t fix it” mentality when it comes to updates since we discovered we weren’t Shop Now the only ones to face this issue.
An at-home freeze dryer is a major investment, so you’ll want to be sure to find a model that suits your needs. Here are some important points to consider when shopping around.
