Using the "experimental" version from the main website, i ran into a food dehydrator.
A deer ran into my current house/base and i managed to kill it, providing several chunk of meats.
Testing the device, i noticed it took 2 chunk of meat to provide 1 dehydrated meat (and sadly as that's a new character, he wasted a few chunks)
So i'm currently the proud owner of a dehydrated meat.
First the bad part.
Eating a dehydrated meat provide 18 nutritions (and make you thirsty with -3 quench), the 2 chunks of meat required for it would have provided 40 nutritions, and if both cooked would have given 100 nutritions (+ 16 enjoyability).
That already sounds like a really bad trade.
Looking on the crafting menu, making a rehydrated meat (to avoid the thirst hit) require 2 dehydrated meat + clean water.
But the result will still provide only 18 nutritions (and give 2 enjoyability)
So basically to generate a rehydrated meat and get 18 nutrition+2 enjoyability you would have used 4 chunks of meats (80 nutritions total) that you could have cooked and get 200 nutritions (and provide 32 enjoyability), and wasted 1 clean water in the process.
The nutrition side is simply a complete waste with the current numbers.
The main interest would be on the big games hunting and spiders attack, when you usually end with much more chunks than you can eat in 1 day, and the 2nd day they would all be rotten making it annoying to waste so many potential food.
With a dehydrator, you can then at least save those chunks for when you'll stop wanting to hunt or loot food and do whatever else for several days.
But looking at the description, "remain edible for an incredibly long time" does not tell you really how long you can stockpile them.
But still, 18 nutritions for all the meat component required, that really sounds weak.
