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.

Places like Craigslist are great for buying more or less anything, but there are more specialized online stores for used electronics, such as EquipNet.utilizando; you can also find used freeze dryers on eBay and Amazon.

It’s always best to buy directly from the manufacturer, and many companies list their products online to view, although not all list prices online.

The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.

Reinstalled the vacuum hose and capped far end of hose to do a hose test. (same results as pump alone)

They come out as dry and hard as lumber. So, if you try to freeze dry a steak or roast, expect to break a tooth eating it.

Freezing is a simple, quick way to preserve foods. Fruits freeze well and retain their distinct fruit flavor. Texture is usually softened somewhat by freezing, but serving partially frozen fruit with ice crystals will compensate for texture changes.

What tastes best? Some foods may taste better to you using traditional preservation methods, others may taste better to you preserved by freeze-drying.

In any case, a working appliance – particularly a refrigerator – will save you a great deal of cash. The following will go over exactly how you can save money by being proactive, rather than avoiding a broken appliance entirely.

It is fun to experiment with innovative preservation methods, but carefully consider the consumer purchasing points above: Know before you go.

Now that I've filled you in on why the most affordable freeze dryer is the small Harvest Right, let's talk about how you can score one without breaking the bank.

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)

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 get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....
