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.
5 Posted October 24, 2015 Hi everyone - new member to the forum, and I was drawn here by this thread. I have been using my HR freeze dryer for a few months now and it's been great. Reading about all your experiences shows that I'm not alone in loving this machine!

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.
The appliances that you buy will need to be specifically determined by your kitchen space, and the types of food that plan to be be serving.
Agree entirely on the fittings! After many emails and phone calls to HR, some advice that didn't pan out, and some parts replacement, the unit is back in business! Turns out it was the wire passthrough for the heater wires.
I'll be looking forward to hearing about the weird and wonderful items you produce. Should be an interesting learning curve.

Commercial exhaust hoods serve a couple of different purposes. They can be used to reduce smoke, steam, and hot air from a kitchen during cooking. They can also be used to filter grease and food particles.
You can decide between electric or gas fryers. Electric fryers take a longer to heat up, but they recover quicker between frying cycles. They are also easier to maintain. Gas fryers are able to go to higher temperatures, and they also heat up faster than electric.
A few packaging methods for your food storage and food that is being preserved. Methods including foil pouches, glass canning, and plastic bottles are discussed.
Plus, if you have a garden and want to preserve your harvest or take advantage of sales on produce when it’s website in season and affordable, this is a smart investment to make for the future of your family. Many of our customers say their freeze dryer paid for itself in less than a year.
The key is to freeze as fast as possible then dry as slow as possible. The freezing stiffens the cells so that when it is dried, it still maintains it's shape and texture.
