Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
Let's do a simple math exercise. Non Frozen food put in freeze dryer at an ambient temp of 70F needs to be at -40F before the dry cycle begins. things go linear, each hour the temps would drop the food by 12.
Freeze dried milk Most dairy products freeze dry quite well. I love freeze drying milk. I measure the milk, pour it on the trays, and process it. Then I package either in a canning jar or a mylar bag, depending on how soon I will be using it.
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.
The pros and cons are easy to understand. In fact, there really is only one pro and it’s a huge one. Those who are willing to spend the time and money to freeze dry their own food should do so as long as they’re going to be committed.
I did a couple of batches (peas and carrots, and another load of precooked chicken meatballs cut in half) and it all worked perfectly. Looking forward to trying out some new things and get more info sharing the results.
•Operation allows for recipe customization (up to 10 Thermal Treatment and 12 Drying steps). Control of the rate of freeze. This means that the rate of freeze can be speeded up or slowed down.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.

Furthermore, the modern freeze dryer systems have vacuum pumps and refrigerators which enhances the drying cycles and saves energy.
In times of crisis or conterraneo disasters, having a stash of freeze-dried meals can be a lifesaver. Your family's safety and well-being are priceless. Not only does a freeze dryer set you up to survive, it lets you control the quality and content of your emergency food supply.
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
Depending on how you want to use freeze dried food, it doesn’t have to be reconstituted. There are some freeze dried foods I like to powder in my blender or food processor and then add to other foods. These powders can be used in smoothies, soups, and baked goods.
It's hardly the most exciting GoPro video for sure, and some may think it's about as interesting as watching a tree grow, but if you really want to see the Harvest Right "in action" in order to understand what's happening (not that there's much to see), this provides a Shop Now "speeded-up" way to do that!
