I bought a freeze dryer so you don't have to

What foods do you typically do in bulk and do you grind them into powder that can be hammered into cakes inside the jars?

Make a video on the subject, and educate us well.

I am glad that he explained it so well.... But when freeze dried food, is stored in an air tight container - like a steel drum, with an inert atmosphere like nitrogen, and all the seals are impervious to vapour etc., the food will last forever.... Here in Bumfuck Nowhere, in the dry desert heat, when a jar of water is left beside the bed, you can see the water level drop about 1cm a day by evaporation - from inside the house. So I quizzed Chat GPT - and it was not real briliant compared to my real world experience, but it gave me the equations, and there were very distinct ratios between temperature and vacuum..... AND this machine pulled very high vacuum, down to the boiling point of water - simply by vacuum... he quoted the figure... BUT IF you use a fairly low but easily achievable partial vacuum of 10Kpa, and a temperature of say 60*C - your drying out rate is VERY fast..... I think the machine went down to 0.05 Kpa.... 101 Kpa / 14.7 PSI is standard atmospheric pressure - so dropping it to 1.4 PSI / 10 Kpa is a high vaccuume, but it's easily achieved.... and you don't need truly sophisticated vacuum pumps to do it.... The idea of freeze drying it to remove virtually all moisture to stop the food from supporting life and causing spoilage... SO the speed and temperatures of the process are important....

or dehydrator...

There are ways to combine drying the air - prechilling it with an evaporative cooler, and then by freezing it, with a refrigerator, and then preheating the air from atmosphere, back to ambient, and then using the hot gas from the compressor, to heat the food with dry air, all while under a fairly hefty vacuum..... similar to this but rolling in pallets of food for drying.... Using combined and staged cycles and heat extraction and heat injection.... Like lowering the circulating gas, from 20*C, down to say 8*C by staged evaporative cooling (very cheap and almost no power), BEFORE running it into the sub dew point (condensing) temperature of the entrained water vapor under high (enough) vacuum. ---- Go Here: https://chatgpt.com/ Ask This: what is the dew point of water in air at 10 Kpa, 8*C and 20% humidity? ------------- Which leads me to conclude that the layout of the condensing stage is better done, AFTER the compression stage...... being a recirculating gas. AND chat GPT began to fuck up badly by this stage.....
