I also love finding clearance deals on produce and other items. My family is no longer surprised when I bring home piles of produce, meat, cheese, or whatever else I find a deal on.
With that said, I’m married to a woman who puts me to shame with her mechanical maintenance abilities, so after a couple of struggles with changing the oil she now has it down to an art.
Looking at the picture you can see the water drops on the insulation and where the water had flowed down the back of the front panel.
I take trips to larger stores to stock up on gluten-free and lactose free staples. Then I can use those to make meals or freeze dry the individual components.
Obviously things like ice cream and marshmallows you would want to let the freeze cycle run longer. When I'm ready to start the drying cycle, I open the door, remove the insulator, and check the temperature of the food on the trays with an infrared thermometer. As long as it's below -10F I start the dry cycle. A side note for TonyC, have you ever thought about attaching a mirror to each side of the tray rack to reflect the radiant heat back in to the trays? I've looked at some mirror finish stainless on ebay, and it looks like you could do it for about $40. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....

Of course the bags were frozen right in to the mass of berries so it was quite a painful struggle to get the mess to the point where I could hack off slices of the berries to put on the trays.
The longevity of freeze dried food depends on the what the food is and how it is stored. When stored in a mylar bag with an oxygen absorber, many foods can last up to 25 years. If stored in a glass mason jar with an oxygen absorber and a vacuum sealed lid, food can last about 5 years.
So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is a picture. It worked great today when I flushed the pump to clear out the gunk.
The evaporator coils Know More that touch the surface of the stainless steel vacuum chamber reach about -42 F. With food in the chamber and because the location of the thermister is on the middle shelf of the four shelves, the temperature it records is going to range from -25 to -30 F in the nove hour default freeze time. This temperature is very adequate for freeze drying the food.
This is the case with meats as well. The trick with meats is to cook out as much fat as possible, then run it under water to remove even more fat. However, you can also freeze dry raw meat as well.
The right drier for the job, regardless if it is for mass industrial use or small batch pharmaceutical ones, can dramatically increase productivity, minimize waste, and save money in the long run. In this article, the process and techniques of freeze drying, the necessary features when picking a freeze dryer, the use of it in pharmaceuticals and food, and the future of the industry are discussed.
5 Posted September 16, 2015 Thanks dsheidt. I was afraid that the AN8 fittings I could find might not be long enough to provide the space needed so that the oil website could flow over the top of the filter, especially given my "disk" method of holding up the can.
Have an understanding of which kind of food pretreatment is needed to use the device. To ensure the freeze-drying approach is productive, you’ll must understand how to get ready food.
I, too, have noticed a significant difference when I defrost mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
