I can't get my hands on anything remotely resembling a vacuum pot where I live, not even online.Realistically, how feasible is to weld two containers together and suck the air out of between them so I can cook meals for virtually free?I already use a food thermos to passively cook pasta, rice, noodles, but something like the stanley pot would allow for bigger meals like stews.
>>2969795Realistically you will build a cooking box. Vacuum - or low pressure air really - isn't the only imsulator there is.
>>2969800InterdestingI wonder what material would keep cooking temperatures for at least two hours
>>2969806Insulation. Straw. Anon, this is very, very old tech people have been using for many, many years. All you need to do is take one pot, find another that fits inside it with room and fill in the gap with anything with high insular properties.
>>2969810Like imitation crab meat?(I have to much!)
please elaborate on this, you put your food under a vacuum? and it makes it cook with less heat? even like a big stew?
>>2969812Idea is you get your food going in a pot to boiling, then add it to the cooker where it continues to cook without adding heat because it's insulated. Sort of like how you put your piping hot coffee or tea into a good thermos and it's still piping hot hours later, but with food.
>>2969813Rather than cooking in a pot then transferring it to an insulated pot which is essentially a giant thermos, just make an insulated box. Cook the food in the pot, then put the pot in the insulated box. Much simpler and half the cleanup required.
>>2969820This, plus you're not wasting heat transferring the food to another container and having to heat that container up as well...
>>2969820Agree, but anon was asking about the idea of a cooking pot. You can buy them here in the states in vintage/thrift shops.
>>2969813oooooooooooooh i see, you cook it normally then transfer to thermos. should be very easy to make your own>>2969795>how feasible is to weld two containers together and suck the air out of between themi get you now, yeah, totally. you may find your weld has pin-hole leaks, so it might be better to tack it then use some adhesive, i'm a big fan of pink grip, that's what it's called in the uk anyways, dunno what it is. but it's good stuff, sets hard and adheres to everything.
>>2969795old style pressure cooker.VIOLA! vacuum pot.
>>2969837You don't cook it normally. You just bring it to a boil, then transfer it. It saves energy by no longer having to heat the pot to keep it at boiling.
>think cause cee buble fud saf>no get how anusrobic bakteareeah livenjoy botulism dumbshit
>>2969795You can't cook in those stanley pots, I've tried it. I tried to cook some rice in it, even preheated it twice with boiling water before pouring in the rice, and even after 8 hours it never even cooked. What you want is one of those lunch box electric hot pots.
>>2969865This doesn't work on the large bowls. Maybe the smaller thermos you could get away with it.
>>2969813Cooking is a process of adding heat to material to chemically change it to be more digestible or taste better. How could you keep adding heat to the food to cook it if your plan is to stop adding heat to the food? Your food will just get cold instead of cooking.

>>2970303It's a matter of heating the temperature of something to a specific level. Then it is done. The "problem" with stovetop cooking is most of the heat is not transferred to the food, but lost through the walls and top of the cooking vessel, thus you have to keep adding heat. Moreover, the max level you can heat water to is 212. The idea behind these cooling vessels is that you are able to transfer all the heat to the food and none is lost through the top or sides, making it far more efficient. It does work and that's why it's been used for hundreds of years to cook with.
>>2970327This. If Stanley made something like their crock pot and added electric to it like those electric lunch boxes, it would be lit. The hottest those crock pots get is about 170F and goes down hill from there very quickly. You're not cooking anything in 170F in those big pots.
>>2970327>It's a matter of heating the temperature of something to a specific level. Then it is done.Sure, but the chemical and physical changes that occur in food when we "cook" it are endothermic so getting it to a certain temperature takes a lot more energy than the textbook heat capacity of that material would imply. A bucket of 100C water doesn't have enough energy to cook an appropriately sized input of vegetables.
>>2969813So the vacuum is in the walls of the container, not where the food is, right?
>>2971887>A bucket of 100C water doesn't have enough energy to cook an appropriately sized input of vegetablesIt does, in fact. Remember, anon, that when you raise a food to a boil in water, you are also raising the temperature of the water in the food itself because the food is mostly water. This is a common method for making hard-boiled eggs, for example. You put the eggs in, raise it to a boil, then cover and remove from heat. The eggs will be fully cooked in about 12 minutes with no further heat added. Of course there are limitations. Your food pieces have to be of a uniform size. You can't cook a whole potato this way. This method of cooking is for stews and soups where the pieces are bite-sized.
>>2969795I don’t see why this wouldn’t work so long as the seals are tight. Are you using one of those vacuums sealers? Many come with a port to connect a hose. Install a hose big in the pot and suck out the air. Or if you can’t get it to seal, stick the whole thing in a vacuum bag
There are solar cookers that use this principal… typically you’ll see a parabolic trough with a vacuum tube along the focal point. A tray with food sits inside the tube and food is cooked without fuel very quickly. A durable kit like that puts be great for camping or for the homeless

>>2969806Just use a portable ice chest/coolerI used to pasteurize straw for mushroom growing by filling a beer cooler with straw and hot water then shut the lid. It would still be scalding hot hours laterAlso, pic related
