Everyone enjoys a good blend. Apparently, not me
though,
people always want to blend at such uncouth hours.
Then,
they seem keen on blending ice, rocks or church bells.
The
point is, they're uncivilized kitchen appliances.
So, to control the noise, I propose that the blending
vessel
be
a vacuum flask kind of construction. This will have
many benefits. 1. The device will be less noisy. 2. Once
the icy concoction has been blended, it will stay icy for
longer.
Problems: Getting the drive through to the blades might
be
a bit more tricky, nowhere near impossible though...
maybe the very centre of the base doesn't need the
double
wall.... The motor will still be noisy, but if quietness is a
selling point, the manufacturers might deploy some
standard motor quietening strategies.

Won't work; too much accoustic energy will
be transmitted through the structure- the
vacuum will have little or no effect. |
|
| |
You'll have to put an accoustic enclosure over
the entire device. |
|
| |
Move the blender to a different wing. |
|
| |
Or buy a house in the mountains with no neighbors for
three miles in any direction. Nice and quiet up here... |
|
| |
Shirley just placing a second blender would, if spinning in the opposite direction as the first one, emit a sound wave with the same amplitude but with an inverted phase than the original effectively cancelling any and all sound. |

In space nobody can hear ice cream. |
|
| |
The Blendtec Q-Series ICB7 has a plastic cover with a rubber seal around the bottom that significantly reduces noise. |

SOooo [marked-for-tagline]. |
|

A + for any method...in my local coffee shop, all
conversation stops when the blender starts. The
safety nannies at the factory would require ear
protection for the user (not to mention safety glasses,
gloves and hard hat). |
|
| |
Double eye protection for any order including nuts, candy,
or cookie chunks... |

it costs more and has more horsepower than my first
car.. |
|
| |
How is the suction applied? |
|
| |
at the factory, it's a double-walled vacuum flask, with
whizzy blades inside. |
|
| |
Church bells? Blended? Maybe shaken, but surely not stirred. |
|
| |
You're making this too simple. |
|
| |
1) Open outer sphere.
2) Open inner sphere.
3) Place ingredients in inner sphere.
4) Remove battery powered blender motor from charger and insert in inner sphere.
5) Close inner sphere.
6) Close outer sphere.
8) Engage vacuum pump to evacuate air betwen inner and outer sphere.
7) Engage maglev unit which interacts with magnets in mixing motor to levitate inner sphere in relation to outer.
9) Blend!!! |

Oops, now I need to find a way to quiet that vacuum pump down a bit... |
|
| |
From the title I had expected a new method of blending, i.e. via explosive decompression. |
|
| |
Surely the best blender would simply be one of those forging steam hammers, just chuck the ingredients onto the anvil and in one swish movement a thin layer of smooth liquid covers every available surface. Mark II could feature a collection funnel. |
|
| |
maybe if it were double-walled AND we evacuated
the air out of the main chamber? We could probably
make up some spurious nonsense about the absence
of oxygen preserving the vitamin c or something.... |

//Getting the drive through to the blades might be a bit more tricky// It wouldn't be if you put the drive in the lid, like a milkshake mixer. |

|
| |
Use a diffusion pump backed by a cryo-sorbtion pump - they're completely silent in operation. |
|
| |
About two or three years ago, I wanted to try to build a
vacuum blender. The benefit I wanted, though, was easier
mixing-in of powders (e.g. protein powder) because the air
would not get between the powder particles and the liquid. |
