Calculation
To calculate the
capacity of a blender we will have to find two things which are as
follow,
#Volume of
blender
#Bulk Density
of product
The following formula
is used to calculate the blender capacity
The
volume of blender (Litres) × Bulk density of the product
How
to calculate Volume
To calculate
the volume of blender water is added into the blender.
We can add a
measured quantity of water by marking a container.
For example,
take a calibrated measuring beaker of 5 litres and add 10 beakers into a
container and mark it 50 litres.
Then add 50
litres filled container into the double cone blender to make it brimful.
Say we add 6 containers to the brim full of double cone blender.
50×6
= 300 liters
So the
brimful capacity of double cone blender in litres is 300 litres.
The
calibrated flow meter can also be used to note the brimful volume of
double cone blender.
How
to Calculate Bulk Density
To calculate the bulk
density of a product (powders or granules) the following formula is used.
Bulk
density= mass/ volume
For bulk density, we
have to find two things which are as follow,
The mass of
the product (granules or powders)
The volume
of the product (granules or powders)
Weigh some quantity of
product (granules or powders) on a measuring balance say it’s weight is 300
grams.
Add this product in a
measuring cylinder and note the volume occupied by the product( granules or
powders) for example it is 400 ml.
Find bulk density by
applying the above formula.
Bulk density=300gm/400ml
=0.75gm/ml
How
to calculate blender Capacity
As we discussed above,
for blender capacity calculation we use the following formula,
The volume of
blender (Litres) × Bulk density of the product
Put the values of
volume and bulk density which are measured in the above section. As we
know Volume is 300 litres and bulk density is 0.75gm/ml
300×0.75=225
kg
So Brimful capacity of
double cone blender 300 litres in kilograms is 225 kgs, for a product having
bulk density 0.75gm/ml.
Now if we have a
product whose bulk density is 0.8 then the brim-full capacity of 300 litres
double cone blender in kgs will be calculated as follow,
300×0.8=240
kg
As we noticed that
with an increase in bulk density of a product, the capacity of the same
blender(300 litres) is increased in kilograms or kgs.
Maximum
Working Capacity
In the above
example, 225 kgs is the brimful capacity of 300 litres double cone blender
for a product with bulk density 0.75gm/ml.
As a general
rule, some space should be provided for the movement of product in the
blender to ensure uniform mixing.
We can not
add product up to brim-full capacity.
Usually, for
maximum working capacity, we take 70-80% of brim-full capacity.
So if we
take 80% of 225 kgs then,
80/100×225=180
kgs
180
kgs is Maximum working capacity of 300 litres double cone blender for a product
having a bulk density of 0.75gm/ml.
Minimum
Working Capacity
Usually
30-40% is used for minimum working capacity.
Minimum
working capacity can be calculated by validating the results
Conclusion
The
capacity of blenders should always be taken in litres, not in kilograms and the
bulk density of every product is calculated to determine its actual filling
weight in blenders.
