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.
Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)
1. Inadequate Drying Time: If your food is not completely dry after a cycle, it may require additional time. Always check moisture levels before sealing.
What type of oil does the vacuum pump use? Harvest Right freeze dryers use food-grade vacuum pump oil, which is available for purchase. One gallon typically lasts several months with proper filtering and maintenance.
Obviously things like ice cream and marshmallows you would want to let the freeze cycle run longer. When I'm ready to start the drying cycle, I open the door, remove the insulator, and check the temperature of the food on the trays with an infrared thermometer. As long as it's below -10F I start the dry cycle. A side note for TonyC, have you ever thought about attaching a mirror to each side of the tray rack to reflect the radiant heat back in to the trays? I've looked at some mirror finish stainless on ebay, and it looks like you could do it for about $quarenta. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....

Of course the bags were frozen right in to the mass of berries so it was quite a painful struggle to get the mess to the point where I could hack off slices of the berries to put on the trays.
The Celiac diagnosis was the real catalyst that made up my mind to purchase a freeze dryer. I can now freeze dry my son’s favorite homemade gluten-free foods as well as a few pre-made gluten-free foods that are safe.
The process involves freezing the food and then reducing the surrounding pressure to allow the frozen water in the food to sublimate directly into vapor. This method is particularly effective for fruits, vegetables, meats, and even complete meals.
My teenage son has Celiac Disease, which means his body cannot process gluten. Unlike with many food allergies, if a person with Celiac Disease consumes gluten, it will do permanent damage and can lead to cancer. Once we received my son’s diagnosis, I started researching to learn what he can and cannot eat.
Reinstalled the vacuum hose and capped far end of hose to do a hose test. (same results as pump alone)
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
Recently we took a trip to website Hawaii. After doing some research, I found a few restaurants that I was fairly confident would be safe for my son. website However, I also knew how expensive even regular groceries are in Hawaii, let alone gluten-free food.
Monitoring the FDer internal temps and once I see -40F I start the dry cycle, except for high sugar content food which I give an Em excesso hour. I'm still experimenting with Ice cream and a few fruits to determine optimal freeze time to get the best results. The cooling cycle ends up much shorter.
And they are so much more flavorful than what you buy at the store. Again, I like to powder vegetables and use them to thicken soups. My family doesn’t even recognize when I add powdered zucchini to spaghetti sauce!
