I'll be trying combined foods next. The Small size works here. The pictured instructions are helpful. The reading material gets you off to a good start and you can get Harvest Right App for endless possibilities!
4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
The current and emerging food crisis in the United States has millions of Americans very concerned about the future. From supply chain shenanigans to food processing plants “inexplicably” being compromised to bird flu decimating the poultry industry, it’s pelo wonder there has been a sharp rise in the “prepper” food industry.
the "real" vacuum pumps on those machines, with ultimate vacuum levels a few more demial places over. I've chased many a leak in my time,but it was: A.
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 $40. Not sure if it's worth a try or not. I would think it would let you harvest right 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 longevity of freeze dried food depends on the what the food is and how it is stored. When stored in a mylar bag with an oxygen absorber, many foods can last up to 25 years. If stored in a glass mason jar with an oxygen absorber and a vacuum sealed lid, food can last about 5 years.
The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an ethernet cable.
And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
12 Posted September 16, 2015 You've given me an idea. I have the parts at the shop to use an actual filter head and a spin on filter. I could have a bracket laser cut and powder-coated that would hold the filter/head assembly horizontal which would allow it to completely drain and the outside Know More of the filter would stay clean.
Lean meats work very well. Meats can be freeze dried either raw or cooked. If you are processing beef or pork, be sure to remove as much fat as possible first.
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)
Harvest Right’s lyophilizer/freeze dryer is the perfect addition to any laboratory. The scientific freeze dryer can be completely customized with your preferred processes.
How often should I change the oil? You can filter the oil using the included oil filter to remove impurities, but it’s best to change the oil every 20-25 batches or when it appears cloudy.
