Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
Finding used freeze dryers isn't easy. That's because most people who get them consider them a long-term investment. As such, they hold on to them for years. However, a used freeze dryer or two sometimes makes its way onto the market.
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.
For ground meats, it’s a good idea to cook and then drain off as much grease as possible. I like to rinse ground meat before putting it in my machine to get rid of even more fat.
seis. Warranties and Support: Look for models that come with warranties and reliable customer support options.
Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
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, get more info 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.
What I presume was happening was that condensation was building up on the cooling coils between the insulation and the chamber and freezing. When I finally turned the FDer off it took 3 days for the ice buildup to melt and slowly soak through the insulation and drip onto the counter.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
adding insulation on the 3 ports on the chamber (One time thing - the drain and vacuum ports are very easy to get to)
- Complete Meals: Casseroles and soups can also be freeze-dried for convenient meal prep options later on.
This is why so many people are buying their own freeze dryers to use at home. The market is essentially cornered by Harvest Right, which isn’t a bad thing since their quality and customer service are both superb.
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.
Dehydrating simply removes the moisture by using heat to evaporate the moisture to dry it. Freeze drying retains more nutrition than dehydrating in general.
