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.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
Freeze drying with the Harvest Right Pharmaceutical Freeze Dryer completely removes all the water from organic material in about 24 hours. There is pelo other preservation method that can come close to eliminating the water from organic material this quickly.
You cannot run a good commercial kitchen without plenty of food. Commercial walk-in coolers are needed for keeping a lot of food chilled. If you’re running a very large scale operation, then a standard-sized refrigerator will not be enough.
I did a couple of batches (peas and carrots, and another load of precooked chicken meatballs cut in half) and it all worked perfectly. Looking forward to trying out some new things and sharing the results.
You can count on me sticking around to talk about the food side of things! My wife looked at me a little oddly when I got the freeze dryer, but now she's a fan too. I'm discovering things that it can do that I hadn't expected, such get more info as making low carb snacks.
8) The vacuum port was up next. You can see the condensation on the brass fitting. That means cold is escaping and heat is getting into the chamber. This small section was placed inside the panel.
Hey there, fellow self-reliant folks! If you're all about preparedness and want to take your food preservation game to the next level, you've probably considered getting yourself a freeze dryer. But let's be honest – freeze dryers aren't exactly known for being wallet-friendly.
You can determine when the product is dry by feel or by calculation of the amount of water remaining in the product.
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.
Removing water quickly is very important because the longer a harvested plant or compound retains water, the higher the chance it has of spoiling, losing nutrition, and losing potency.
Run full system test with no 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)
Making jerky safely requires either the use of curing salts (containing nitrite) or enough heat in an oven or dehydrator so that the heat will kill organisms before they multiply.
Most pharmaceutical or laboratory-grade freeze-dryers have to be purchased from licensed manufacturers. These sales often need to be done over the phone or in person with an equipment salesman, though those can be found online. Some options are also available online at places like Amazon.
