Long ago. and B. I don't have the test equipment I did then. I guess what I'm saying is don't be afraid to get too technical with me in your answers. What I wouldn't give for a helium leak detector right now...

Furthermore, the development of vacuum drying and the control of temperature rise have increased the efficiency of the freeze-drying systems which leads to reduced cycle times and lower costs. The development of the industry gives a lot of hope for the future of freeze drying in both the pharmaceutical and food industry.

Not only does this save time and money, it saves the headache of trying to throw together a last minute meal if we are in a hurry. And again, it cuts down on food waste.

Over night the FDer warmed up and the next morning we had a massive puddle under it - running off the counter onto the floor. I cleaned up the mess, but the next day the puddle was even bigger. On the 3rd day it was back again just as large even though I left a large towel under the FDer.

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 $quarenta. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....

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 harvest right freeze dryer installed on the FDer.

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 initial cost can be high, they require adequate space and power supply; also, they can be noisy during operation.

Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.

- Cost-Effective: While the initial investment can be high, freeze drying at home can save money in the long run by allowing you to preserve leftovers and bulk purchases.

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.

The current and emerging food crises in the United States have 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 no wonder there has been a sharp rise in the “prepper” food industry.

Both pumps come with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for no oil spray at all and it will last much longer.

This electrical dryer is successful and reliable, and it offers extras you received’t locate in other equipment, like a lengthier guarantee along with a cycle which can minimize lingering pet hair. However, People bonuses come with a steeper cost tag.
