Have you ever tossed out spoiled produce or leftovers? How about those cans of food that are nearing their expiration date sitting on the shelf at the back of your food storage?

It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.

Our electricity was very high when we had it in AK because our electric company charged a lot, but in Texas, it’s very cheap to run. I don’t mind that I can’t freeze dry some things, as most of the things that you can’t freeze dry, you can purchase commercially or they shelf stable as is. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:

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.

This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.

Freeze drying lets you say goodbye to food waste by extending the shelf life of your food. Every dollar you save on groceries goes back into your pocket.

It failed to reduce the moisture in the oil... I'm in the process of modifying it to catch and suspend the moisture in the container long enough for desiccant beads to absorb the water. The air flow comes into the inlet, down the central pipe to the bottom of the screen and filters up through the beads and out the top. I know this was like forever ago, but I thought I would respond anyway. I haven't been on much in a while, I only run my freeze dryer in the winter. So I think you'll find it's a lot harder to remove water vapor from a vacuum than just using desiccant, as the vacuum will just pull the water out of the desiccant.

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

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.

Another emerging trend is the production of environmentally friendly and energy saving freeze dryers. Manufacturers are trying to lower the carbon footprint of their machines by introducing more energy efficient and sustainable devices.

- Nutritional Preservation: This method retains about Buy Home Small Pro Freeze Dryer 97% of the original nutrients in food, making it superior to other preservation methods like canning or dehydrating.

If you have a high volume lab, it’s usually a good idea to have more than one to be safe. Freeze drying ice water hash is the #1 way to dry it because it increases your production speed, enhances its color, retains more delicate terpenes, and sharply limits microbial activity.

Both pumps come with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for pelo oil spray at all and it will last much longer.

The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
