I honestly think putting a thermometer inside the unit is an excellent idea. I sent the following note off to Harvest Right Support in an effort to gain a little better understanding of the process.
4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
3. Power Supply: Most freeze dryers require a standard electrical outlet but check if your home can accommodate the power needs of larger models.
I would prefer those fittings to have internal Este rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the O ring and you're back in business.
Unlike canning or dehydrating, freeze drying retains 97 percent of the food’s nutrients. Freeze dried food also tastes more like fresh food than canned or dehydrated foods.
3. Poor Quality of Dried Food: Ensure that your food is prepared correctly; avoid using overly ripe or damaged produce as they may not yield good results after drying.
Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?
The easiest way more info to reconstitute food is with water or broth. I like to weigh my trays before processing them. Then I write the weight and the name of the food on a piece of masking tape and put it on the front of the tray.
Tray lids– Though freeze drying is underway, you would possibly end up prepping for the next batch. Tray lids are vital in these conditions, preserving your prepped food from contaminants, odors, or unintended spills with your freezer.
Freeze drying preserves fresh fruits and vegetables Freeze drying is a great way to preserve food for short term or long term storage, up to 25 years.
The only downside is that the interior is now so cold that defrost time has doubled! I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
Another best practice is to set up a station. This will take space. Having a freeze dryer, freezer, prep table, and processing area all together has been a good decision. It can all be done in a large kitchen, but the machines are noisy and a freeze-drying project can take up a lot of space.
In these tough financial times, you need a company you can trust with stewardship of your life’s savings. We recommend self-directed IRAs backed by physical precious metals provided by Genesis, a faith-driven gold and silver company.
It's hardly the most exciting GoPro video for sure, and some may think it's about as interesting as watching a tree grow, but if you really want to see the Harvest Right "in action" in order to understand what's happening (not that there's much to see), this provides a "speeded-up" way to do that!
