Homogenous mixing in Industrial Powder Mixers

For Example:

When you open a detergent packet, you can see the white powder mixed with orange and
blue particles uniformly. You can be almost sure that every packet of detergent you open
from that brand has the same ratio of white:orange: blue particles. Hence this detergent
product from the manufacturer is said to be in ‘homogenous mix’.
How does the manufacturer ensure that the thousands of detergent packets that come out
of their packaging line have the exact ratio of white:orange: blue particles? Do they check
every single packet before sealing it? That would be practically impossible. Then how do
they do it?

How do they do it?

All companies which make powder products (powder-powder mix or powder-liquid mix)
including manufacturers of detergents, distemper paints, energy drinks mixes, fruit punch
mixes, cereal, animal-feed, cement powder, cake premix, spice mix etc aim for this
‘homogeneous mix’ in their batches so that every packet of powdered product they sell has
the intended properties and quality. To get this desired ‘homogenous mix’, the
manufacturers run their batches in mixers for extended periods and repeated batches. Only
when quality control officers are convinced that the batch is homogeneously mixed, can it
be sent for packaging.

There are a large range of powder mixers available commercially on B2B websites in the
Indian market. The most common of these are Ribbon blenders and paddle mixers.
While running the batch in commercial mixers does bypass the problem of checking every
packet for uniformity, it does, however, lead to a new set of problems.

1. Not all mixers are designed equal. Conventionally available ones struggle to deliver a
homogeneous mix.
2. Heat generated by the rotary part of the mixer can damage the powder product
(especially in the food industry)
3. Excess Shear stress due to high rpm can damage the particulates
4. Conventional Low rpm mixers will take very long batch times to give a homogeneous
5. Long batch times is a waste of power and slows production line

The Toshniwal Solution:

At Toshniwal, we have been working closely with our clients and our European principals for
more than 2 decades to address these issues and design a working solution for these

The result of these efforts is our range of Twin Shaft and Single Shaft Paddle Mixers which
are designed to create a unique ‘Fluidized Zone’ inside the mixer while running the batch.
The fluidized zone technology enables us to use low RPM paddles which are gentle to the
powder product, but at the same time deliver market-leading batch times for homogeneous

We have a dedicated engineering team which works closely with our clients and our factory
to design and fabricate a custom Paddle Shaft Mixing Unit that is specifically designed for
the characteristics of the client’s powder product. Our mixers are designed to deliver the
following advantages:

1. A homogeneous mix in short batch time.
2. No damage to the powder particles either by heat generation or shear.
3. Efficient working which ensures lower power consumption
