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.
With that said, I’m married to a woman who puts me to shame with her mechanical maintenance abilities, so after a couple of struggles with changing the oil she now has it down to an art.
We’ve bought six so far with two more on the way. But families and individuals considering getting their own can and should as long as they go in with their eyes open.
That also goes for dense foods like mashed potatoes. Liquids or soft foods can be put in silicone molds and frozen. Then pop them out of the molds, put them on the freeze dry trays, and put them in the machine when it’s ready.
seis. Warranties and Support: Look for models that come with warranties and reliable customer support options.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.
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.
The freeze dried food can be used for everyday eating, camping and of course, long term storage. I freeze dry as much as I can while times are good, I won’t plan to freeze dry if I go off-grid or don’t have electricity.
We have a large vegetable garden, and I love that I can pick something and freeze dry it right away. I know where my food comes from and how it was treated. This gives me peace Buy Now of mind in knowing I am feeding Shop Now my family healthy food.
Pre-frozen food takes less time to process since the machine doesn’t have to completely freeze the food. Your climate (humidity and temperature) can also affect the cycle length. My average load takes around 24 hours, but it can be significantly longer.
Thirdly, I like to know what is in my food. When I process my own food, I know what is going in it. Also, I like to grow my own produce so when I freeze dry that, I know exactly where my food came from and how it was grown. Some commercially freeze dried foods contain preservatives.
Run full system test with pelo food in chamber (results, 630 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)
Have an understanding of which kind of food pretreatment is needed to use the device. To ensure the freeze-drying approach is productive, you’ll must understand how to get ready food.
The industry standard machine for drying ice water hash at commercial operations that need serious throughput
