Straight from the udder to your heart
Gross thing I witnessed on the expressway Monday morning:
A dairy tanker spewing milk onto the road. Okay, maybe spewing is a bit harsh of a word. I guess it was more like spraying at a high speed and medium velocity. Yes, I'm quite sure that's it.
Correct me if I'm wrong, but if milk is coming out the back, that means there's air intake into the tank — and not just air, but highway exhaust. I suppose it'll lend a special flavor to the milk.
This is why I'm glad that I avoid dairy as much as possible. Cheese must be sharp so that the lactose has been consumed by bacteria. And milk must be Lactaid or a milk substitute. Otherwise, I'll be the one spewing up my lunch (err, spraying at a high speed and medium velocity?).Bonus link: Since you've gotten this far, I might as well reward you with a link.

Well...
Me am just glad they do all that they do for milk be so as it am. Me got pretty tired sucking it out of cows.
I was always under the impression that any air added was done at the plant, not on the road, in order to create pressure in the tank to help keep it cold (Boyle's Law and all that).
Boyle's Law?? damn.
I like room temperature raw/unpasteurized milk the best, followed by full-fat milk of the pasteurized kind.
Skim milk actually makes calcium hard to absorb..
Well..theres pros and cons, but do avoid if yer allergic!!
de: bad news for you buddy.
temperature decreases with expansion in volume. increasing the pressure increases the temperature.
even then, boyle's law has nothing to do with temperature. It simply relates pressure to volume where PV = constant, which means that pressure is inversely proportional to volume, which makes sense, as if you squeeze something down, its pressure increases, and volume decreases.
Now, if you want to relate pressure to temperature, you have to use a combined gas law. Charles law states that V\T = a constant. But this isnt what you want. The combined gas law is PV/T = constant, in this case the constant is nR. Basically, you are using the ideal gas law, PV=nRT.
But all that is besides the point. Having air in your milk is not a good thing. Air means oxygen, and oxygen means bacterial growth, and other bad oxidation reactions.
I cant really explain this easily, other than get a straw, fill it with water, then close the top. The water doesnt go anywhere, because of surface tension at the bottom not allowing air into the straw, and a essentially a vacuum at the top. Pull your finger off and the water goes down. This isnt due to gravity, because before, the water didnt go anywhere. The water leavign the straw is due to air getting into the top. The same goes for this milk tanker, there was obviously a leak somewhere above the milk line, and a pretty big one, to let enough air in to get a gushing flow of milk out the bottom.
I can only imagine how wonderful gallons and gallons of milk all over the road will smell in a few days.
it rained last night, no stinky interstate for memphis
When you're right, Anonymous Husband, you're right. I'm not sure why I keep thinking that pressure is inversely proportional to temperature. Maybe it was a good thing I didn't major in chemistry :-)
In all seriousness, thanks for setting me straight on that.
::blinks in wonderment:: dude!!
Well guys..this is gonna sound crazy but i actually like the bacteria with my (unpasteurized)milk..don't try it with the treated version though.
..but to see my point i'd have to go into a VERY long explanation.
In the meantime..ur chemistry skills leave me completely in the dark!
The only way air would have gotten into the tank would be if the driver left the air valve open, although there is NO vacuum on tankers, in which case there is also a large bubble of air inside the tank, due to the fact they are not all top-filled, those that are, are custom. Now the only way it could have leaked out of the bottom would be a line that worked loose enroute or a crack due to harsh road surface. As to how either happened as a driver myself I can tell you the answer: NO PRE-TRIP inspection.
