That has lead to me making my own lactose free Greek yogurt and freeze drying it to use for yogurt and sour cream for my son. We also freeze dry lactose free milk for traveling or for any other time we need it. It reconstitutes very well.
In truth, I was also really worried my son would be cross contaminated and end up being sick for a week. The hostess was insistent on making something he could eat and I finally relented. Needless to say, he ended up being very sick from the food.
You can freeze dry things with fat and oils in it. The point isn’t to completely get rid of all the fat, but to reduce it. The reason being is for the storage process.
Then, when I reconstitute, I add back the same amount of water to equal the total amount of milk I originally processed. For example, if I processed 4 cups of milk, I add to the milk powder enough to equal 4 cups. I prefer to use an immersion blender for the best consistency.
April 22, 2025 by Lily James Freeze-drying, also known as lyophilization, is one of the most important processes in the food industry and the pharmacy sector, as it allows for long-term storage of a product without losing its value. Currently, this method is extensively employed for the preservation of active pharmaceutical ingredients, biologics, and food products as moisture is extracted without deteriorating its quality.
It’s super simple, if you aren’t running an Oil Free pump (which we strongly suggest), you should change the vacuum pump’s oil every 20-30 runs (approximately once every month or two with daily use) and ensure the interior chamber as well as your trays are cleaned frequently.
I did wonder though, since this is gravity flow and not pressure driven as on a car, if having the filter mounted horizontally might result in using only "half" the filter, as the oil would tend to travel through the low side of the filter -- although in practice, I suppose, as the filter material gets plugged it would force the fluid level higher.
3) Inside the front panel I installed a plastic shield over the display card and a water deflector just below the hole to route the exterior condensation to an 11x17 pan beneath the FDer.
Tray lids– Though freeze drying is underway, you would possibly end up prepping for the next batch. Tray lids are vital in these conditions, preserving your prepped food from contaminants, odors, or unintended spills with Buy Now your freezer.
We have two freezers in the garage as well. All of these machines generate heat and humidity. Our FDer front regularly sweats up an storm and water drips off the door and from around the entire chamber perimeter down the front of the unit. It got so bad that I taped a plastic shield above the display to route the water around it. You can see the water on the door and on the stainless steel front past the 4 screws on the unit.
Not only does it spread the cost, but it can also increase the amount and variety of the preserved food you store away. Additionally, a group purchase can also lead to purchasing bulk quantities of food to freeze dry.
Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
Freeze drying seasoned squash and zucchini One of my favorite things to freeze dry is vegetables. It’s so easy to put them more info in soups or casseroles. Once onions or garlic are processed, they are great to add to food.
Freeze dried Skittles are a favorite in my family. They end up with a crunchy texture. Other candies have a crunchy exterior and an airy interior.
