We sold a grainmill also, hyped by a friend who had several. Used it some also. Nothing happened and other things incl food was donated or tossed. Now retired, who has time or money to throw away again? not me.
I honestly think putting a thermometer inside the unit is an excellent idea. I sent the following note off to Harvest Right Support in an effort to gain a little better understanding of the process.
In addition, the casing stayed in a Secure managing temperature during our lab examination, even on the best placing.
Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
There are three things that cause organic material to lose its freshness and begin to degrade – Water, Heat, and Oxygen. Harvest Right has a solution to these problems.
So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is a picture. It worked great today when I flushed the pump to clear out the gunk.
1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.
I did have a vacuum hose fitting leak at the FDer port once. I had similar symptoms to yours. I found that the hose would slightly rotate even when the fitting was snug.
White rice, more commonly known as polished rice is a main food source for over half of the world’s population. Rice is an excellent addition to home food storage because it’s versatile, high caloric value, and long shelf life. Families should store about
Some essentials are needed to cook with the main food staples in long term food storage. These mostly are used to make breads from stored grains. The cooking essentials include salt, baking powder, baking soda, and yeast.
After buying our freeze dryer I was naturally curious as to how it "knew" when something was done, since batch times varied so much depending on what was being processed. Watching the cycle times didn't seem to tell me anything at first -- especially without a thermometer to tell me what was happening inside -- until I finally caught on that applying heat to the frozen food affected the vacuum, which provided the measure of how dry the food had become.
Ask yourself useful issues. Could you very easily approach entire meals in a single cycle? Or is it very best to system different types of foods individually? Does one know how to load the food trays?
Options: consumer choices for this appliance are currently limited. There are few companies making “home” freeze dryers, laboratory freeze dryers are built for scientific sampling so may Know More not work as well for food, and the small commercial “pilot study” freeze dryers tend to be larger than those marketed for home use.
You can also use Facebook Marketplace or specialty groups to find used freeze dryers, but most people will list them in specialized stores because that’s where most people will be looking.
