Important note: I’ve never seen a freeze dryer in stock at any Walmart I’ve been to, and they aren’t always available online.
However, manufacturers usually sell their products online or through resellers, so a manufacturer having a physical store is rare.
Here’s a link to their available Harvest Right freeze dryer trays, just as further proof that they do resell Harvest Right equipment.
Drying things out played a roll as well as the added insulation. We had 3.5 weeks of constant rain here in central NC with humidity over 95% and temps near 95F in the beginning and tapering down to 80F by the end of the rain. The condensation on the front panel around the seal had water running down the front of the Freeze Dryer constantly during the entire cycle, not just the freeze cycle. I initially went into the FDer to simply stop the humdity from reaching the outer chamber shell and freezing.
One thing to understand concerning commercial ranges is that they are manufactured in gas or electric models. Both types have their own benefits and disadvantages.
Isolated pump by capping the stack (pelo meter to measure pressure, but no bubbling after a very short pumpdown - pump sounded normal for a high vacuum situation)

Used freeze dryers can also be worth your while, but it’s imperative to check them before buying and be sure they’re working well. Lastly, always avoid websites that sell off-brand equipment and sketchy manufacturers.
Lately, some people have been advocating some very potentially hazardous food preservation and storage practices on foods meant for room temperature storage.
19.7k Location:Ontario, Canada Posted January 25, 2016 So a couple of months ago (when the weather was still warm) Alleguede has his assistant drop off some raspberries that he wanted me to freeze dry for him. Since they were IQF raspberries I assumed that they would be individual - but apparently when you leave them in the trunk of your car long enough to thaw, then put them back in the freezer - then take a couple of days to get them over to me - they are no longer going to resemble individual raspberries.
