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.
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.
Commercial grills come in all shapes and models, and it’s important to purchase the one that is best suited to anything you are cooking in your restaurant.
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.
One oil free pump. The oil free vacuum pump can be used with Shop Now any size freeze dryer. They are quiet, fast, and easy to use. The Harvest Right oil free vacuum pumps do not require oil changes and do not require regular user maintenance.
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.
I'll be looking forward to hearing about the weird and wonderful items you produce. Should be an interesting learning curve.
You get all the same when you buy a freeze dryer in person, but buying it online takes less effort (and it’s more comfortable since you’re sitting on a couch).
You can determine when the product is dry by feel or by calculation of the amount of water remaining in the product.
Most other methods for extracting water also destroy enzymes and terpenes due to heat being used in the extraction process. Because freeze drying does not use heat during operation, the enzymes and terpenes in freeze dried products are not destroyed.
I didn’t know you had this feature till one day i got an email and that got me to the sitio were i started looking around. This way I can take a couple months instead of hitting my saving and paying for it at once.
Dehydrators take the water off the surface first, then water eqilibrates with the surface, more water is drawn off the surface. You are left with a shrunken item, with some residual water. Makes gorgeous leather.
Options: consumer choices for this appliance are currently limited. There are few companies making “home” freeze dryers, laboratory freeze dryers are built for scientific sampling so may not work as well for food, and the small commercial “pilot study” freeze dryers tend to be larger than those marketed for home use.
adding insulation on the 3 ports on the chamber (One time thing - the drain and vacuum ports are very easy to get to)
