The duration of the storage would be long enough to cause some damage. To the experienced tongue, it would unacceptable.
As the temperature goes, keeping temperature all the way down in cryogenic freezer would help, except its not economical...
And yes, they would be sealed individually in an...
I need to preserve frozen food (uncooked) as long as possible.
One of the damages caused by long term storage would be enzymes in the food itself.
If it is a raw product, i can't exactly heat it up to denature the enzymes.
Can i however, use other methods?
I was thinking electricity...
Instead of the usual
B = μ0NI for field inside solenoid...
how should i go about finding the field let say... 10cm away from one end of the solenoid
1. directly at the z-axis
2. not directly at the z-axis
this is assuming the solenoid has finite length, finite number of turns ,finite...
Thank you you gusy for all the helps so far.
The concept of using ice to chill the water is very possible if there is a company that actually manufacture frozen sea water, which i doubt since it ruins their machine, and its harder to freeze salt water. I cannot use normal ice because it affects...
$3000 per 7 tons of LN2 seems to suggest around 50 cents per kg. I did quick search on "how much liquid nitrogen cost" and it suggests around 5-10 cents instead. Can you elaborate on this? Are those super low price only feasible on insanely large quantity? Isnt a few tons daily not large enough...
1. I would need to chill it from 27-30 to around 20 (sea water)
2. I would need to be able to replenish around 20-50 tonnes of chilled water within 15 mins
3. I would be using a large water cooler to keep the temperature down afterward but i could also do nothing since i would need to...
I have this need to be able to rapidly chill (not freeze) water without lowering its O or increasing CO level
I am currently thinking using LN2 due to its lower solubility in water than O and it being somewhat safe
My question is,
1. How safe it is exactly? I really need to chill it...
