ADVASCO SCALES LTD

Want to sell packaged coffee to your own customers or onsell to other cafes and coffee houses?

Advasco Scales can help you with scales for manual packing, for automated packing and with custombuilt equipment for those special coffee projects.

Velvet Coffee Roasters in Henderson worked with a manual system for many years – sitting down with the roasted beans and paper packets, loading the coffee in then checking the weight on a small scale.  But they recently decided to move over to an automated system – so Advasco built them a machine designed specifically for their purposes.  Now, instead of being constrained by roasting times and needing to  deal with those roasted beans within a limited time frame so the next load of beans could be put in for roasting, they can now put the roasted beans into their custombuilt machine, do other work while the machine does the measuring out and then stops  - and best of all, the roasting machine no longer rules the roost!

About 60kg of roasted beans fit in the hopper and slide easily down the chute into paper bags.  The system shuts off automatically when the correct weight is reached.  The custombuilt machine is working like a charm - and Velvet Coffee have outlets all across the North Island - so everyone’s happy, the workers and the coffee drinkers!

Velvet Coffee have as their symbol an elephant and a rhino,

and they support wildlife sanctuaries in Africa,

both travelling across to Africa to do voluntary work in

sanctuaries, and supporting them with donations.

It's great to see a company putting something back into communities.

Probably everyone's heard about the second law of thermodynamics - which states that the entropy of any isolated system always increases.  In common language - chaos - something we're all familar with at some time in our lives....

But on Monday May the 20th 2019 - that was World Metrology Day - we all took a step away from chaos!

Since 1889 the official International Prototype Kilogram (IPK), a 90% platinum/10 % iridium alloy highly polished metallic cylinder with height of 39mm and diameter of 39mm has been housed at the International Bureau of Weights and Measures in France. Unfortunately, material objects lose or even gain tiny bits and pieces over time - that's the nature of physical reality (something else we're probably all familiar with!) There were various official copies here and there in the world. Interestingly, over time, it had been observed that the mass of these copies was moving away from that of the IPK, and nobody knew whether the copies were losing mass or the IPK was gaining mass - talk about chaos!  The problem was in micrograms - not good for precision measurement!

And no matter how much the Official Kilogram weighed - it was always the Official Kilogram - even if it had - or  maybe hadn't - changed a bit.

But - the new definition defines the kilogram in terms of the Planck constant - that's a concept in quantum mechanics and it's about how electrons release energy in discrete steps, called quanta, and it can never change.  The Planck constant is defined by the characteristics of atoms in the element cesium and it's taken years of hard work to figure the Planck constant out - measuring the very smallest thing there is to measure.

If you're interested to read about this, there's a great description here <https://www.vox.com/science-and-health/2018/11/14/18072368/kilogram-kibble-redefine-weight-science>.

And not just the kilogram, but also the ampere, kelvin and mole have been redefined based on the fixed numerical values of the Planck constant (h), the elementary charge (e), the Boltzmann constant (k) and the Avogardo constant (NA), respectively.

So here's the new definition of the kilogram -

The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10^-34 when expressed in the unit J s, which is equal to kg m² s ^-1 , where the meter and the second are defined in terms of c and ∆νCs.
