[chew@PPLe 0]

Anybody has recommendation on which brand to buy? Those that you boil your food, throw into the pot, no need to run on electricity but food will continue to cook throughout the day?

Want to get one so can make yummy soup

Are u referring to pressure cooker?

I think is not the pressure cooker... The one she was referring is to boil the food, throw into the "special" pot, and the food will continue to cook throughout the day... is the "special" pot she wanted to buy... I ever saw the demo somewhere...

From what i see, it's just a just a pot providing another layer of "seal" to prevent heat from losing too fast. So that the inner pot got time to cook whatever its inside.

If u mean making soup. By the time when u need to drink the soup, probably it has already cool down n u need to reboil.

So why buy such expensive pot when u can just boil ur soup, leave it there, and then reboil it when u wana drink again ?

It looks only to keep the soup warm till you want to drink it. Just heat up, dun be so lazy

it is not to keep the soup hot like thermal flask... it is used to cook the food inside....

Stewing purpose?

cook ?

ask youself this question first,

to cook something, we need energy to provide the heat to cook food

So where is the source of energy for this pot ?

think the term for this pot is the 'thermal pot'

first put the stainless steel inner pot on open fire and bring contents to boil

while boiling, quickly put the inner pot into the vacuum pot and close the lid. the vacuum ensures that heat does not escape into the surrounding. therefore the boiling process will continue for a much longer time compared to leaving the pot outside...

cheapest i have seen is $69 for a 5litre pot

different brands different prices, just like woks

ya, like what i said, u boil your food, and then put inside the pot.

The main function of the pot is to retain the heat, and prevent it from losing too fast. So that the heat can cook whatever inside.

How long can it retain the heat? it depends on the thickness of the pot and the quality of the seal..

Primary school science teaches u Conduction, Convection, Radiation. These are the 3 areas which will casue your inner pot to lose heat over time.

the more branded ones like tiger tout their products to retain heat for six hours

thinking of getting one for my new home too

coz boiling soup takes three to four hours

and must watch over the fire, quite leceh...

Conduction cut off by vacumn in between the two walls of the thermal pot, convention reduced by enclosed area, radiation of heat is redirected back to inner pot (that is boiling) through reflective surface of the interior of the outer pot. I think pri school also teach the applications of understanding how heat dissipates.

My colleague recommends Tiger, he said he tried other cheaper brand but doesn't work as well. The thing is I don't see it in Courts or Best Denki...

[applefreak 1]

maybe you want to try Tangs, Robinsons, Isetan, Taka or OG

all should carry it...

Tiger ah, very expensive leh

think in the range of $150 - $300
