Jeanine L. Albert was quick to respond to my inquiry about the delivery of our harvest right freeze dryer. I hope companies will have more “Albert” in their team for the satisfaction of their customers! Thank you so much Trimleaf for helping us purchase this great product! Team Albert here!
Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)
(had to replace the whole galvanized T piece with new wires in it) Seems they are epoxied in there, and in my experience passthroughs are a problem spot, so it's not at all surprizing that there was a slight leak there. In any case, I thanks the folks at HR for sending parts and sticking with me throughout.
Adele Faubert Albert was very helpful in answering questions prior to place the order and then with following up on delivery. The unit arrived on the date scheduled even though the tracking notice was not updated once the unit arrived in Canada. The pre-arrival instructions were very helpful as we were prepared once the unit arrived.
A dehydrator dries food by using heat only, while a freeze dryer uses both cold and heat. Dehydrated food still has moisture in it and works for short term storage only.

Door seal appears good against the plexiglass side, even stripe of contact, nice and wide. Inside gasket groove has been checked for debris and cracks. Looks OK, but the design seems odd to me!
The one "gotcha" I encountered in making this is that a typical car oil filter attaches with a 3/4x16tpi threaded pipe. I could find no such pipe anywhere. My solution was to use instead a 3/4x16tpi bolt, and then drill a hole through it.
With increased need for freeze-dried products, innovation in freeze-drying processes is evolving. One prominent direction is the implementation of AI and automation in which businesses can track and adjust freeze drying times more easily.
12 Posted September 16, 2015 You've given me an idea. I have the parts at the shop to use an actual filter head and a spin on filter. I could have a bracket laser cut and powder-coated that would hold the filter/head assembly horizontal which would allow it to completely drain and the outside of the filter would stay clean.
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.
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 Know More 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.
Both pumps come with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
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!
